Jaguar XJ40-R Race Car Project
Discussion
Well that was an epic weekend.
The sun stayed out and some family came down which was nice. I never got time to test the car so here's how the weekend went:
Saturday - Qualifying, realised the gearbox mount is so shagged the box and prop were hitting the underside of the tunnel whilst spinning making a horrendous noise. I crapped it not knowing what it was and came in after 3 laps. Further investigation (frustration) showed it wasn't doing much damage but sounded worse than it was. I used a mini ratchet strap to try and limit the movement but it came back during the race.
Saturday Race - I qualified dead last obviously but off the line I made 4 places, which would be the finishing result for me as I couldn't get passed the red X300 of Roger in front of me, still putting up with a dreadful noise and getting to know the car. Epic fun though
Sunday race - Very eventful. We start that race in the same positions the cars finish on the Saturday, so I was up the field a bit. But another good start ment I made another few places. I then had to avoid a big crash on paddock hill and managed to sneak by another 4-5 cars. I then pushed on harder than in Saturdays race and managed to stay in position until a bit of underside trim fell off. This sounded very bad, so I pulled in only to find out it's just a bit of underside trim. I didn't go back out, which I regret.
30 cars started 20 finished, several incidents that are being looked in to, thankfully none of which I am involved in.
For Castle Coomb, she's going on a diet which I'll add progress pictures of, and we are sorting the horrendous gearbox mount.
I'll try and edit some of the go pro footage and get it up here
Cheers

So Castle Coombe was last weekend. What a brilliant time I had, such a nice venue. Quietly crapped myself when at 10pm I realise I forgot my race suit, gloves and boots so had to do 280miles round trip, getting back to the paddock for 2.30am 
But the racing was great, first time on the track and the car performed well. Still need 888 tyres and suspension setup and I'm down on power, but it was great. I managed to take the guy in the purple XJS but he simply had more power than me so took the position back on the straights.
Finished where I started on both races. Car didn't overheat but brakes went off slightly. Going to try and get the 888s for the next race and also perhaps some power modifications, next stop Anglesey

Thanks guys. It weighs 1640 with me in it, so the heaviest car in the whole series right now. To get a bit more power I'm fitting an advancing bracket that a local chap makes to give me a few more degrees on the timing, new exhaust and then get it set up on a rolling road. Obviously it's class A so my options are limited. I already have the sport manifold, but some guys change the cams as well.
Off to my unit this afternoon to cut the inside of the doors out and strip the window mechanisms and start getting chop happy with the wiring loom
Cheers

As an up date, the seasons over now
It was great fun, won drive of the day award @ Donnington which is an epic track and loads of fun. Oulton park was great as well, we qualifying allowed me to get 7th on the grid, but a dry race saw me fall well back dwarfed by more powerful and more modified cars. Lots planned for winter. Will up date soon with full list of work undertaken in preparation to become more competitive next season

It does look like fun! And excellent pictures too.
Is there a power advantage to routing the air filter through the headlight?
I only ask, because the Sovereign spec 'Fishtank' headlights are so much lighter than the quad headlights, yet no one races a car with them.
I did notice slightly more mid range punch, but I really can't say whether it brought much of an advantage. I'll be taking out the other main beam light before next year on my constant quest to lose 100kg all over the car.Is there a power advantage to routing the air filter through the headlight?

Awesome stuff that looks like great fun. I would love to start club racing but sure looks like an expensive hobby
It depends how you go about it but If you run on too tight a budget it zaps a bit of enjoyment as you worry about the car more etc but I'd confidently say if you budget £15000 a year for a car, prep, trailer (poss tow vehicle) race entry that should see you through a year.AceOfHearts said:
