30 dowel trigger wheel fitted

I removed the nearside driveshaft again last night, and slid the 20 dowel printed trigger wheel off, and replaced it with the latest 30 dowel version. The ECU then had the new CAL loaded, and I set the wheel speed sensor up for 30 teeth. This will allow 12° rotation of the wheel per pulse, which coupled with the 20 dowel trigger wheel on the front axle, should make a further improvement to the launch and traction control. With the wheel fitted, I can spin the axle around by hand, and the ECU displayed some very smooth data from the sensor, which is currently adjusted approx 2mm from the dowels. I will need to keep an eye on the dowels, which only weigh 0.5 grammes, they shouldnt move, but we'll find out at Blyton.



A question that came up on facebook recently was whether the steel dowels would come out when the car was being driven. So I've just done a quick calculation, and at 150mph, with the rear wheel rotating at 2227 rpm, the dowels have an effective mass of 133.6 grammes per dowel. Which sounds a lot, but, to push the dowels in to the plastic ring, requires over 10kg of force. That is, if I place the ring on to my kitchen scales, and push the dowel in to the ring, the scales are overloaded before the dowel is forced into the ring. And as the scales have a max reading of 10kg, I take that as more than 10kg of force to insert each dowel. Thats the theory, lets see what happens at Blyton.


The entry list for the Blyton sprint is now out. Only 75 entries though from 120. Not a great turn out.

Fifth injector update

The 3rd version of the fifth injector assembly turned up from 3D People at the weekend, and everything fits together properly now. The orb fitting on the injector rail works perfectly with the AN6 fitting I bought from torques. And the O-rings on the Pico injector seat properly in the fuel rail and the main body. So I guess its time to get one made from aluminium now and see if we can get it working with the ECU.



I also have the front and rear trigger disks back from 3D People, and I've populated two of the rings with 4mm dowels. The steel dowels weigh just 0.5g each, so even when fully populated the plastic rings arent that heavy.

Corner weight check

I took a trip over to TripleM motor sport today for a corner weight check and to have the new Avon wets fitted to the rims. Alan and Nick placed the car on the scales, and to my delight the car was just a couple of kg's off front left to right rear, which was easily adjusted by altering the length of the right rear pushrod. They also checked the toe and camber and nothing needed adjusting. Alan then clamped the brake pedal closed, and they turned the front wheels to see how much torque was needed to turn the wheels against the brakes, and both wheels required the same amount of torque. So the reason the front left keeps locking under hard braking maybe down to the pad materials in the new pads. If the front left locks again at Blyton, I'm to swap the pads over left to right, and see if the issue goes away.

I drove past the show ground at Lincoln on the way back, and there were huge queues of lorries and tractor units, for exhibitors for the truck show at the weekend. I was glad I wasnt caught up in that traffic.

RSR Escort front and rear trigger disks designed

Just getting prices for laser cutting these speed trigger disks for an RSR Escort. The front features 24 teeth and the rear, 12, and both are 4mm thick.


I should be getting the printed parts back next week. I've had a delivery of another 200 4mm dowels, ready for inserting in to the printed parts which I will be testing on my car at Blyton on the 19th.

22Apr

Printed gearbox trigger disk

The 20 tooth 3D printed trigger wheel is now fitted to the output cup on the Hewland box, and in testing in the garage, the GT101 sensor sees the steel dowels as they pass; so I've edited the CAL to set it to 20 teeth, and will test the ring out at Blyton in just over 3 weeks time. I've also sent to print 24, 26, 28 and 30 dowel versions, which I'll also test. The 20 tooth ring gives me 18 degree's of rotation per pulse, which will again help improve the launch and traction control. The GT101 will switch up to 25KHz which is way beyond the number of pulses it'll see at 160mph.

20Apr

Fifth injector v3

The modified cad drawings for the third revision to the fifth injector parts are away for printing. I've changed the fuel rail to use an ORB-6 boss which will give a better seal for the AN6 fuel adaptor when its fitted. This took some headscratching to achieve; I used a 1859N107 adaptor from the McMaster library, and redrew the fuel rail around it. I think it looks great, and cant wait for the parts to come back.


For the past 3 weeks I've been helping a student at Leicester Uni, develop code to display BMS data on their Dash4Pro. It started off with them discovering they didnt have the CAN license, which was easily sorted. And after that I've been helping them understand the format of the data as it comes across the bus, and how to align the frames with the numeric controls on the display. Its all working now, and I look forward to seeing the finished product when they've completed their project.

After designing RLM their wheel speed trigger disks and sensor bracket for their race winning Cup car, I'm getting busier now with requests from other people. I've just sent off some other components to print for another client, and I've supplied some additional NPN speed sensors to another customer in Scotland. If you need any parts designing or supplying, please get in touch.

I have also sent off to print a range of front wheel trigger disks, with 22, 24, 26 and 28 dowels in them, which I will be testing on the Mygale. Parts should be back at the start of May.

If you want evidence of how the higher number of pulses per revolution improves launch and traction control, this video shows me launching at Anglesey, with 0-60 in just 3.1 seconds. I had the quickest launch of any single seater all weekend. As the car launches, the ECU automatically shifts 1st to 2nd then 2nd to 3rd, so I just have to hold on tight and enjoy the ride. There's also some clever stuff going on with boost and throttle position during the launch stage, but I cant say what that is, you'll just have to work it out for yourself.

CAN BUS simulator - completed

Today I created a CSV file which contains the CAN data which would normally be generated and sent by the ECU during a run. I then wrote a short Python program, that transmits the data to the Dashboard over CAN, via the Raspberry Pi 4 Model B. It reads the CSV file, and sends six frames at a time, 20 times a second, and the dashboard displays the frame data as it would in the car. That now allows me to test the Shift lights or the numeric controls, without having to run the engine or drive the car :D

I started by exporting the logged data from the ECU, from a run from Castle Combe last year. This is exported from LifeVIEW to CSV (@ 20Hz). Then using Excel, I imported the CSV and converted the data in to HEX and then in to CAN frame format, based on the DBC file I'm using. This ensures that each frame sent by the Python program, contains the data that the dashboard is expecting, to allow it to display the data as a numeric control etc. The CAN frame data is then saved back to CSV, and copied to the Raspberry Pi where the Python reads the file, and line by line, writes the data to the CAN BUS.


The source code is available at the following Github repository.

Here is a short video showing the process.

CAN BUS simulator

I've interfaced the Dash4Pro to a Raspberry Pi 4 Model B, which allows me to send test data to the Dash over CAN, to make sure that any changes to the display design, can be tested, prior to driving the car. At Cadwell in March I arrived at the track to find that the engine oil pressure wasnt being displayed, due to an orphaned control. I can now modify and test the display, at home, without having to run the engine :D The project page is now live

11Apr

3D parts arrived

The Mk2 version of the fifth fuel injector parts came today, and although I've now found the right profile for the IW048 injector to push in to the main body which sits above the throttle body, I hadn't transferred those dimensions across to the fuel rail, so frustratingly the o-ring on the Pico injector wouldnt push in to the rail. It was the chamfer that was wrong which I've now resolved, so off to print we go again. If the Mk3 version fits together, then I'll go straight to manufacturing.


The 30 dowell trigger disk also arrived, and after fitting the 30 steel dowels, I am just left with fitting it to the front wheel for testing.

The Dash4pro worked perfectly over the weekend, after I'd remedied the issues with orphaned frames. What I'm writing at the moment is a piece of Python to emulate the CAN Data stream sent from the Life ECU. I am using an Inno-CAN board, from Windows, which is running python inside IDLE. I am just waiting for a second 9-way D-type breakout to arrive, and then I can connect the CAN Hi and Lo's together and provide 12V for the D4P, and I should then be able to transmit data to the D4P which it will then recieve and display. This will allow me to fully test the Dashboard on the desk, rather than having to run the engine to ensure all the frames from the ECU are being intercepted and displayed.

10Apr

1.1G launch

I'm positive the 20 dowel printed reluctance ring is helping with the launch and traction control. The car did a 2.2s 64ft launch on Sunday, and recorded over 1.1G. I've got some 30 dowel plastic rings on order, which I'll fit to the same left front wheel, to further increase the resolution. And I'll fit the 20 dowel printed rear ring for Blyton, so see if that also further reduces the 64ft time.

9Apr

Missing flags

After a lengthy conversation yesterday with the CofC and the Stewards, where I asked what the contents of the Motor Sport UK Stewards report for the meeting would contain, an explanation was given, for the missing red flags, and after some further dialogue, the situation has been resolved to my satisfaction.

8Apr

A weekend to forget

The less said about Anglesey the better. I cant get away with writing that though; a hell of a lot happened, and it was chaos with Storm Kathleen blowing gale/storm force winds all weekend. Needless to say, it was a battle to get through both days unscathed.

Saturday

Saturday was frequent showers, and a damp/drying or wet track, and I was on slicks most of the day, including the first run off when a quick shower fell just before the Run Off, we had the wet track, which then dried for the following drivers, and their times improved accordingly. I also ran the wets on one dry run, just to avoid the damp patches on a couple of the corners, and they took a battering when it was drier, but the times showed they worked in the dry, I was joint FTD at one point using them, the other driver on Slicks! The National circuit worked well, but the Hairpin was exceptionally difficult to slow down for, with the tailwind. And the exit of the hairpin was wet all weekend with a stream running across the track. I didnt score well, but was happy just to survive. No faults on the car, and the driver certainly enjoyed the banter and challenging circuit.

Sunday

Sunday was awful. We had heavy rain at 4am which woke most of the paddock. My van was buffeted from side to side, and it wasnt a good place to be. The winds weren't reducing in strength, but at least when we ventured out and unlocked the garages, the track was drying out, and the skies were blue.

We did P1 and T1, and by 11am were waiting, prepared, refuelled etc to do the first run off in ever improving conditions. But the organisers decided we'd have an enforced early lunch, starting when the T1 batch had finished. And the forecast was rain for 1pm. We stopped for lunch at 12 Noon, and at 12:45, with darkening skies, we were all called to the line. I lined up with my best slicks on, and set off around 1pm, and monstered the car around. It was a fantastic run, even with rain appearing on the visor at Rocket. When I finished the run, the timing screen at the finish showed Pete's time, and it was a very slow time, and I knew straight away there was a problem. In the pits I checked the phone to see the live times, and myself, Pete and Stephen Miles were all given times of over 100 seconds, but the splits showed I was easily the fastest of the three of us. But then the rain started to come down, and we were told we all had to take re-runs.

I quickly fitted the wets on the car, and jumped back in to have a re-run, otherwise I'd only score 13 points for not having a time. Pete and Steve did the same thing, and we were soon being glared at by the competitors still waiting to take their runs on slicks. Why wouldnt you fit tyres appropriate to the conditions?

I didnt queue jump, I waited my turn and when I set off my glasses steamed up and I had no idea where I was going, Pete had the same issue; and none of us really had a good run. When I returned to the pits and parked up, John Graham complained about the changing of tyres, said it wasnt allowed, but there is nothing in the rules about it. And I have seen dual driven cars change tyres between driver changes, so the precedent has been set.

Consequently, the Run Off 1 run was scrubbed, due to the weather and timing equipment fault. We were told that, while queuing for the 3rd timed run, and that the 3rd timed run was now the first Run Off! Which wasnt ideal. After that run we were then given another 5 minutes to prepare for the 3rd timed run, and that went as well as expected.

But was the 3rd timed run also going to be the final run, and therefore the 2nd run off, or would we get another one?

About 30 minutes later we were told we had a fourth and final run, and so we prepared. The track was drying, but I opted to stay on wets, and some of the corners were still quite damp and I didnt fancy a spin.

So for the final run, the 2nd run off, I set off after Goulding, and was surprised to catch him at the finish line. Had he had a problem? I asked Pete what had happened and he said he had spun ahead of me.

Nothing much else happened; we busied ourselves with packing up, and Smiles celebrated a run off win with his music. I left at 4pm to make the journey home.

After I arrived home, I was told about a red flag and re-run for Smiles. Apparently I had ignored the red flags and continued at race speed. I immediately felt guilty for not seeing the red flags. I honestly didnt see them. The CofC decided not to punish me for ignoring the red flags, and my time was allowed to stand. Again, what red flags?

On Monday morning, Smiley shared a pair of screen shots of the onboard from his Run Off 2 video, following me around the track, and he did have static red flags shown to him. What? How could I not have seen them? So after I unloaded the car on Monday morning, I took the SD card out the camera and checked the footage, and low and behold, there were no flags shown on my Run Off 2 run.

Make of that what you will. Why was Smiles shown the red flag for Petes spin and I wasn't? He was affored a re-run as he'd slowed down. But no red flag for me is a major failure; If Pete hadnt cleared the track ahead of me, I'd have had zero warning, and could potentially have driven in to him, or taken avoiding action and left the track!

It was a crap result in the end; Smiley went on to take FTD on his re-run, on warm tyres, a good ten minutes after his first run, and he capitalised on the opportunity to take the both run off wins, and the overall championship lead.

All in all, I'm not impressed. The lost run off win from the aborted Run Off 1, and then the subsequent red flag farce in Run Off 2, isnt the standard we expect, and at this level, isn't acceptable. To be accused of missing red flags, when they werent even shown, isnt acceptable either.

On the bright side, I completed seven runs on Sunday, with no issues, and didnt take a spanner to the car all weekend. That's how it should be. The next round is at Blyton Park in 6 weeks time.

Anglesey prep

The entry list is out for the Anglesey weekend (6th & 7th April) and its not a bad turnout with 15 drivers battling for the top 12 point scoring positions. I'm hoping for better luck than when I last went in October 2023, when the core plug burst. Travelling home on Sunday with some wins under my belt will be the best outcome. The forecast is pretty poor, with heavy rain and strong winds forecast for most of the weekend. I've no changes on the car other than replacing the pair of 3D printed plastic turning vanes that sit ahead of the rear wheels. The replacements are printed thicker, to make them both tougher, and hopefully less prone to stone damage. The dash4pro has been reprogrammed, to try and resolve an issue I'd created, by giving some of the frames 'friendly' names. Fingers crossed it doesnt have any more ophaned numeric controls.

Printed trigger disk a successs

The 3D printed front wheel trigger disk with 20 dowels was a total success at Mallory. Never missed a beat. The traces on the ECU are so smooth. I will have to get another pair printed with 30 dowels and see how well that works.

Runoff winning video

Gerards needs a lot more commitment, can be taken significantly faster, and not in 4th gear. When we go back in June I'm hoping to have more grip, so we'll see if the times can be improved further.

Saturday

Cadwell was freezing cold, dry, but very very windy, and I just couldnt get my car to turn in. It was 5s quicker when I put the Pirellis on for the first run off, and I finished 2nd. But I just had no confidence, and on the final run off I was 4th. I couldnt work out what was wrong, it was great at Mallory on Thursday. Very odd. Anyway, I won BARC Members FTD, which was collected for me by a friend, and I went home, for some hot food, a shower, and centrally heated house to thaw out. The car required no work, so I left it all in the trailer for Sundays trip to Mallory Park. Over the five runs, the car used 7.8 litres of fuel (approx £54 worth)

Sunday

On sunday morning I left Leicester at 6:30am and was at the Mallory paddock for 10 to 7, found a spot in the paddock and unloaded the car. The day was forecast cold, and sunny but dry, and rather than risk the Avons I ran the 2 year old Pirellis all day. To rectify the understeer from Cadwell, I removed both the Gurney strips from the front wing elements, and it transformed the grip. So clearly they weren't necessary, and thankyou to Graham Porrett for the suggestion, he said they didnt work on the Lola. A useful tidbit of experience handed down.

First practice went well, the car was handling properly now, and I was second fastest to Pete Goulding, and my wife arrived just as I was starting the lap. She stayed with me all day, and it was great to have some company, and someone to clean the grit from the tyres.

The first timed run was taken before lunch, and I improved, as did Pete, and we then had a 1hr lunch break. The first run off was after dinner, and I shot round 3s quicker to record a 64.01s lap. But Pete pipped me with a 63.95 to take first. I new what I had to do for the final run, take Gerards with some more speed, however, I downshifted from 6th to 5th, and it didnt down shift, so I downshifted again and it then went 5th then 4th when I lifted off, due to the stack shift system which queues up downshifts, which I completely forgot about. That cost me half a second, and I was slower with a 44.75. But so was Pete, and I finished a quarter of a second ahead to take my first Run Off win of the year.

My best run wasnt recorded on the camera (technical fault), but the second run off win was, so I will overlay the data today and get the video up. My best lap, using the Edwina's chicane layout, was a 45.3s, measuring the full lap from the same point on the track (the Edwina's chicane). My highest speed was 155mph (GPS speed) on the approach to Gerards.

Aside from removing the pair of gurney strips, I didnt take a spanner to the car all day, and only removed the engine cover once to show a friend the engine. A perfect day. During the four runs, the car used 6.600 litres of fuel (approx £42 worth)

Next up, Anglesey in two weeks, and I am 2nd in the championship, with no work required on the car. The new floor skirts worked perfectly, as did all the other aero mods. Very happy.

21Mar

Testing success

No issues at Mallory today, the car is extremely fast now, the aero mods were making a very big difference allowing me to run the front and rear wings at shallower angles than I've ever run, and the grip from the Avons was outstanding. I now have engine coolant pressure data to work through, and the gear system pressure sensor also captured the air bottle pressure during changes, with no issues. The plastic printed front wheel trigger disk worked perfectly, so I will look to fit the opposite front at some point. Now I need to give the Avons a quick clean and load up for the trip to Cadwell tomorrow.

20Mar

Tyres cleaned

I took the heat gun to the Pirellis, which were new in August 2022, and I'm hoping I can get another season out of them. If not, I'll fall back to the Avon HC3's.



The 3D printed extraboost fifth injector port has turned up, and it looks great. I'm still waiting for the pico injector to arrive, and then I can do a test fit on the plenum with the spare throttle body.

19Mar

Trailer washed!

The best tool for getting 12 months of dirt off a clamshell, is the Karcher T-Racer surface cleaner/rotary patio cleaner. It makes very short work of getting all the muck and stains off. A quick wash with some soapy water and a rinse afterwards, and it came up great.

18Mar

Trailer rewired

Over the weekend I've fitted a much larger battery to the trailer and rewired the remote winch and the motor mover to connect both to the battery through an isolator switch. It's another Bosch battery, so comes with, a four year guarantee. A no brainer based on the warranty swap I've just made on the battery from the van. The next job is to connect the battery to the 13pin trailer connector, so it is trickle charged when the engine is running on the van. Actually the next job is to pressure wash the clamshell. Five months parked in a field, isnt the best way to keep a trailer clean.

The finals are out for both Cadwell and Mallory Park, and its going to be a full on weekend making both events back to back. There is no paddock plan for Mallory, 'park at your discretion', so who knows where we'll all end up. I do hope there is a someone coordinating the paddock, as it'll be hard to get everyone out in the correct order otherwise.

On Friday I finished off all the jobs on the car, I just need to fill the fuel tank, reset the fuel consumption on the ECU, refill the dive tank so I can replenish the air in the paint ball bottle. Oh and fit the mirrors for Thursday.


15Mar

Brake pads changed

I fitted the fresh front brake pads last night, which is only a 30 second job as they're held in with spring clips. The pads they replaced are a few years old, and had half the pad material of the fresh ones.

I also removed the 3rd spring assembly to check that the grease inside the sliding mechanism was still allowing it to slide easily, and it was fine. I then sprayed some fresh black paint on it, and reassembled it once it had dried.

The final job was to stick the pair of turning vanes that I'd printed, to the floor, just ahead of the rear wheels, and I did that with Sikaflex. I'll see what difference they make at Mallory.




14Mar

Reluctance rings

I've just finished designing a front and rear wheel speed sensor setup for a well known competition car builder in the UK, and they are hopefully getting them manufactured and installed for an event in just over a weeks time. The brief was to have 20 teeth for the front and rear reluctance rings, and design a bracket to support the speed sensor on the front hub. I went for a folded steel bracket to keep the costs down, and the reluctance rings can be water jet cut from mild steeel.

I also provided a design for a 3D printed ring for the rear axle, with 30 holes for 30 steel dowels, to test. The printed ring would give 50% more pulses than the steel ring, and its just a question of robustness when used on a car designed for a full race series.

13Mar

Nosecone fitted

I've added the pair of fasteners to the nose cone, so it can now be attached securely to the car. I weighed it last night and its almost 800grammes lighter than the one it replaces. And I've replaced several of the cap head bolts on the front wing brackets with 10.9 button heads, to smooth out the air flow under the nose. And the last of the four gurney strips is now fixed in place, just the pair of turning vanes to fit ahead of the rear tyres.

Pleased to see John Graham has registered for the championship again; John won in 2019, and is still driving the red Gould which he won the championship in. Not sure which dates he'll be out, the entry list for Cadwell should be out in the next day or so, so we'll soon see.


11Mar

Nosecone replaced

This weekend I fastened the gurney strips to the rear diffuser, using epoxy resin, and stuck the first of the two strips to the front wing. I then fitted the wing, and tried the new nose cone for size, and it fitted straight on, requiring no modifications to clear the redesigned front wing drop plates. So I stuck the race number to it, and I now need to drill a couple of holes in the rear of the cone to rivet the fasteners to it, so it can be bolted securely in place. One more gurney strip to go, and the aero modifications are complete.

The entries opened this morning for Anglesey and Blyton, at 7:14am the email arrived from Longton, and luckily I had my phone on whilst I was eating breakfast otherwise I would have missed it. I have entered both events; Anglesey is in less than 4 weeks time, and Blyton is in May.

Good news on the van battery front. The one I just replaced was just under four years old, and had totally failed, so I sent it back and claimed on the four year warranty provided by Bosch, and I've just been refunded the full cost of the new battery I bought. Thank you Tayna Batteries and thank you Bosch.

7Mar

Exhaust refitted

Zircotec returned the exhaust pipe yesterday, it had to go back for a tiny bit of rework, and it looks fantastic bolted back on to the turbo. I hope it retains the matt black look after I've blown exhaust gas down it at 750°C.

I then replaced the three very short pieces of 6mm nylon pipe used by the pneumatic system, after I spotted an air leak via the pressure sensor readings from the ECU. You couldnt hear air escaping, but the pressure kept dropping, so I'll see now if the pressure is retained.

In my spare time I'm designing a few parts in Fusion, one of which is a fifth injector plate for the EcoBoost. You can find very few people selling these; there are a few in the US, but they come as a complete kit with electronics and a black box; whereas we just wanted the ability to run an additonal injector. So, with a small bit of help from Jenvey with the Pico injector inlet and outlet port sizes, I drew this. Its ready for 3D printing, to test the fitment, and then I'll get one made for testing. Prices with the Pico injector should be in the £300 range. It has a groove for an O-Ring on the underside, where it meets the throttle body.

Front wing drop plates upgraded

The pair of redesigned front wing drop plates arrived today, so I fitted them to the car and they are smaller and lighter than the Playskool ones, and I now have a pair of spares in case anything unfortunate happends to them. Very pleased with how they turned out. I designed them in Fusion to have scallops both sides :D

The spare turbo hoses arrived and I've replaced the 135° hose which had some tiny splits in it where the jubilee clip had been holding it on to the turbo outlet.

4Mar

Printed aero sections fitted

I've bonded on the pair of aero profile sections to the leading edge of the floor. They're held on with sikaflex, and wont fall off. The final two pieces of printed parts to fit are the turning vanes that will sit ahead of the rear tyres. I'll have a go at fitting those tomorrow. I' waiting for some more carbon angle to turn up, which will be used a gurney flaps on the front wing and for the rear diffuser. Delivery is due on Wednesday.


3Mar

More jobs completed

I'm now turning my attention to the electronics changes that I needed to make. I've updated the CAN Datastream from the Life ECU, to include ECP and GSP pressures, and after updating the DBC file in Kvaser, I've reprogrammed the Dash4Pro to display an alert when various channels are outside of normal ranges. eg EOT is above 120C; It's the first time I've actually set alarms on the Dash4Pro, and I'm quite impressed how well they work. You do need to change the variable names in CAN on the D4P, so it displays something meaningful in the warning screen, rather than the frame and slot number and some obscure shorthand for the message.

To test GSP (the air pressure in the pneumatic gear system) low pressure alarm, I simply operated the paddle switch with the clutch switch closed, and selected first then neutral, and the 95psi air pressure quickly dropped below the warning threshold set, triggering the LOW warning to be displayed on the dashboard together with flashing red LED's. When I then opened the paint ball bottle valve to repressurise the system, the pressure went back up to 95psi, and the alarms stopped. So yes, very pleased with how easy it was to set everything up. When the warning messages appear, I can either clear by pushing a button on the Display, or wait 5 seconds and the message will clear automatically.

I found an issue with the 45° hose that exits the turbo and directs the compressed air towards the intercooler. Where its been clamped to the turbo with the jubilee clip over the years, there were a few tiny splits appearing in the silicon, so not taking any chances, I ordered a spare, and that will be fitted this week. Thank you to Viper Performance for having them in stock :D

Mallory Park is go

Great news, the organisers have stated that even with just 80 entries, they are 100% going ahead with the Mallory Park sprint, which means my test session a few days before should be fruitful.

1Mar

It's Spring

Yep, just 21 days to go to the first event. I have finished the floor upgrades, with the addition of another piece of angle carbon, kindly supplied by Easy Composites. I bonded the aero covers for the diffuser support brackets, using sikaflex. So they shouldn't fall off. I rewired the fp1 3 pin plug, having done a rush job in October when I was diagnosing the fuel pressure issue. It's now properly covered with adhesive heatshrink. I then spent a while tie wrapping cables out of harms way, in the area behind the seat, which were all again done in a rush when I refitted the engine last year, and it's all far tidyer and hopefully, wont cause me any issues.
