cant power brake?

Sport mode on (red led lit),
push the trac off button
and let'r rip!
You can't power brake these cars, but you can burn some rubber from a stop with the above mentioned.
Another possibility is that there's something wrong with your car. Secondary fuel pump is dead, dirty MAF sensor, etc, etc... Does it run strong when you get on it hard??
I reread your post. The S button will actually be in the up position to be on. It's reverse psychology if you ask me. Maybe the little red led is burned out??

when the intercooler pumps fail you get restricted performance, cause well, the intercooler and intake air becomes too hot and causes detonation which will damage a engine. Hense restricted perf.

There is a pump on the pass side between radiator and engine that pumps the intercooler's coolant loop, that would be the first thing to check. I think it should be running anytime the car is on, so you can turn key on without starting and feel the pump to see if it's on.
anyone know the part number for the bosch pump

Forget Power Braking.
Dude, This is a jag, remember?
If your posting on this forum, that means your car is over 15 years old.
Power braking and old jaguars are a bad combination unless you've modified the whole power train.
With the TRAC control off, I can light up the tires as long as I want from a standing start.
Power braking will only destroy the transmission sooner.

I power brake my car frequently, before and after LSD install. Usually to warm tires when i'm at the strip, sometimes when I have a passenger/spectator looking for thrills or lots of smoke.
With that being said, you should be able to drop the hammer anytime with no brakes applied and do a nice long "one tire fire" burnout with ease. So yes, something is lacking. I still can do a decent burnout from a standstill with no power braking and both of my rear tires gripping. The ultimate reason I installed LSD was to stop all of the wheel spin from starts.
Another short disclaimer.....I beat the hell out of my cars and wouldn't advise others to treat their cars as I do unless you feel like keeping up with the maintenance bills/repairs

Have you looked over/drained/flushed the cooling system at all? it's possible, especially if all that coolant has been sitting for a while without being circulated, that something's gummed up in the intercoolers or radiator. There's a procedure for filling and bleeding the intercoolers, I don't remember the order of operations but it involves opening up that 19mm plug on the "v8 plate" and filling through there, then cycling the car on/off so the blower IC pump runs and circulates coolant the IC loop.
Black soot in the IC pump doesn't sound promising either.
I don't remember the exact thermodynamics with heat-soak and performance, I think it's got to do with the reduced efficiency of the supercharger when compressing hot air as opposed to cold air.
