Let's be sure we're both talking about exactly the same thing:
BHP= HP at the crank, right? That's what it says here:
http://en.wikipedia.org/wiki/Horsepo...ake_horsepower

Through a 6spd, drive line loss is about 15%. So 500bhp=425rwhp.

Now, with a US-spec Mkiv Supra, 425rwhp is pretty tough, even at 'full bpu'. If you had a brand-new (zero miles) Mkiv Supra Turbo, it'd be different, but I assume we're talking about one of these with a few miles on the odo, right?

Just guessing, I'd say it's possible with a very low mileage JDM Mkiv Supra Turbo to hit 425rwhp, with BPU++++, race fuel, and very high boost. However...among other things...it'd be pretty darn hard on those smaller, ceramic turbos. Realistically, I'd say don't even try. You might get close, but hitting it would take a lot of reasources - resources that could be better spent on going to a single turbo kit for a more cost-effective horsepower/$ increase.
Alternatively, nitrous+bpu could get you there without any trouble (assuming the nitrous is installed, controlled and tuned properly).

Again, to give it a shot, you'll need to push the BPU++++ spec as hard as you can. Read up more about it here:

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
