Hello Guys n Gals

Some of you may have seen my old thread on the XJ40-R Race Car. Well that car did me proud in the Toyo Tyres Jec Saloon and GT Championship and I took home 1st in Class A this year, and the car has become a great friend, gonna miss the old girl. She's now for sale!





So now that class is done n dusted, a new project is beginning. We are going to build a full on Class D supercharged X300 XJR in Class D. This will include perspex, fibreglass body work, lots of weight loss, sorted suspension, big brakes and a well sorted (400bhpish) 4.0 AJ16. Watch this space for more updates, 6 months to complete



Cheers

Are you keeping the auto of going manual? Sounds like a cracking build.

Cheers gents
Manual donor car is currently being stripped so she will be fully manual
Will get her on the dyno next week so I can see what power it makes as it sits

With the caveat that I know nowt about Jags, why not do everything you plan to the existing one which is already very capable?

I believe it's extremely complicated to get a supercharged AJ16 to work in an XJ40.

Hello all

Well the XJ40 is now sold, new owner intends to race the car next season which is great. Bit sad seeing it go, but onwards and upwards

With regards to why I didn't use the XJ40 and fit the R engine, it was merely because I've been told that the getting the engine in, and running would be a bit of a pig. Also the XJR already has bigger brakes etc, so out the box it's more capable. I also fancied a change after 3 years if I'm honest

Dyno day tomorrow, and the Gearbox goes in! Exciting

Mega stuff gents! Hopefully you won't need any spares

So she's partially stripped, and jsut got back from the dyno. Very strong power was made (300hp and 400nm) but afte two runs, 35hp was lost as a result of high charge intake temps, which is a common issue on these. So this will need to be addressed. Gearbox goes in next week, then it's off to Emerald for stand alone management.

That looks tremendous. Definitely the best colour for the X300 and X308 shape. Good luck with the build.
