Are those intakes or exhaust peeking through the hood?

In reply to 914Driver: pretty sure thoes are intakes seeing as youd have no backpressure or suction out the hoot like that

go with a t5! much nicer transmission plus youll never be able to actually get into 6th gear, and itll take off like a freight train. and used t5s are dirt cheap (espcially if you dont care as to if they are lasting)

Nope the Turbo 400 transmission in later Jags has a Jaguar bolt pattern not at all like the Chevy, Buick, Olds, Pontiac, GMC, etc.. bolt pattern.. Plus it's not like the passenger car turbo 400 it's the extreme heavy duty one they used for heavy duty trucks. That V12 puts out awesome torque.. (especially considering it's only 326 cubic inches) By the way keep the oil clean and don't overheat it (there are simple no-cost tricks to do that) and expect 300,000+ miles out of it.. Then you can rebuild it and bring it completely back to stock without pulling the engine.. (the cylinder sleeves are removable) The crankshaft is forged and hardened.

Mguar where can I go to learn all these jag v12 tips and tricks?

Back to the brake problem: AngryCorvair is teh brakemaster here. I'd suggest getting him involved, he should be able to point you in the right direction to fix things up.

Merely disconnecting the ABS will leave the pump in the circuit and it now becomes a restriction, that's where the 'no stop' problem comes from. So if you disconnect the pump you need to run hard lines to bypass it (easy to find at the local PepVanceZone). Once that's done you should find that you now have brakes again.

Shocks: crap, leave the stockers in place and piggyback some junkyard Monroes or ??? That's just fabrication. Don't give up the XJ-S ship!

speedbiu, what type of brake problem are you having? Or did you get all that worked out?

mguar, I haven't looked under the front of an XJS in a loooong time. Is there any reason the upper and lower spring mounts couldn't be modified to work with the usual, say, Ford E150 etc coils, making a whole world of stiff boneyard springs suddenly available? Or even put a smaller diameter spring inside the main spring? IIRC on the rear it should be pretty simple to adapt 2 1/2" race springs, those are available pretty cheap used and eBay coilover sleeves should work. I know I'm talking boneyard solutions but that's probably going to be necessary to keep things within a Challenge budget.

In reply to mguar:

NASCAR likely doesn't run ABS because of its fear of anything electronic on their cars.

Formula 1, ALMS and Grand-Am all use it or have used it successfully.

Formula 1 doesn't allow ABS, the teams don't have a choice. Nascar doesn't allow it either for whatever reason. Many of the rules changes in both series' are meant to reduce the performance of the car, not increase it.

From Formula1.com: "Indeed as ABS anti-skid systems have been banned from Formula One racing...Formula One previously allowed anti-skid braking systems (which would reduce the brake pressure to allow the wheel to turn again and then continue to slow it at the maximum possible rate) but these were banned in the 1990s. Braking therefore remains one of the sternest tests of a Formula One driver's skill."

It's possible they banned ABS in an attempt to get rid of traction control, but race teams found a way around that too.

I'd imagine that Formula 1 teams would love to have ABS, especially with races in the rain.

In reply to mguar:

As has been stated before, F1 did use it once. ALMS does in some classes, etc. Most factory ABS systems are not well suited to racing, but that doesn't mean they can't or won't work in this situation.

Yes NASCAR uses an "electronic" rev limiter, but its just an MSD box and is mandated by the rules. Currently, they are not allowed any other electronics in the cars (aside from the radio and Camera systems) Going to EFI is just one step closer to moving to alternative fuels (which is somewhat inevitable from a marketing standpoint, think of the corn growers wetting themselves over the possibility of sponsoring a NASCAR team)

In a straight line stop, my Mom could beat an early ABS system. ABS is not about stopping shorter, it is about maintaining control to avoid the impact. In a panic stop, the rate at which you decelerate is determined by the mass of the vehicle, the amount of friction between tires and pavement.

With that said, lets let it drop. The fact is the Jag needed a cheaper/easier to manage braking system and eliminating the ABS won't hurt it much in the Challenge as any deficit can be overcome with wider and wider tires and flared fenders.

Does anyone remember draguar? from one of the original GRM message boards? Dude talked about building a Jag to compete in the Challenge and then set about afterward getting folks riled up a bit talking about supposed cheaters, etc. Wonder what happened to that guy?

I'm glad you decided not to give up. This sounds like the type of project where you gain lots by simplifying. At least in my experience, those are the most enjoyable builds anyway.
