Ok here'* my tid bit. I have a 1993 SSEI and I've been running the ZEX DRY system for about 5months and used about as many bottles. I've had no problems what so ever other than needing to tune it. This was bolted up to a near stock engine too and right now I have the entire engine torn apart with no sign of damage, even to the rings. I have heard the wet system injected into the TB is a BAD idea with a supercharger. You have to remember every 1psi of pressure raises ambient temperatures about 10deg. So 10lbs of boost = 100deg + Initial temp which would put it about 180deg in the summer, pretty warm. Plus the teflon thing, plus the puddles (which can happen), just not worth it in my opinion. The zex system is pretty safe because it has a control box that will cut it off if the mixture becomes lean. Something to remember, I contacted Holley and Zex and they both said that a dry system on a supercharged application will give you about 10-15hp over what its rated at. So a 55hp shot into a supercharger will yield about 65-70hp in gains. A standard V-6 can handle about 75-100hp safely but you have to retard your timing if you go above 65hp. Thats what I know on the dry systems for the ssei. Now of course the wet system placed under your injector would be the best way to go because its easier to tune and your not blowing all that nitrous over your MAF sensor (unless you use a TB plate with your dry shot). You can also be a little more certain that your getting the right amount of fuel. The dry system management unit will cut the nitrous off if you don't have enough fuel but you lose that power for the rest of your run so it'll cost you 1/4 times. Is it worth the extra $$$? I guess that all depends on your budget.

Wherever you got that information at is WRONG. 1psi of pressure is definately more than 10 degrees. An Intercooler will lower temps 100 degrees or more, it has been proven many times with temps taken after the blower before the Intercooler and after the intercooler. If the intercooler lowers temps 100 degrees and 1psi=10 degrees then I can run an extra 10psi, but unfortunately that is not the case, if it was the case then our GTP would run low 12'*. In the GTP we run about an extra 4-5psi more than what we did before the IC, any more than that and we see KR. So your number, wherever you got it from, is at most 1/2 of the real temperature. Calculated my way I would say that 10psi + 80 degrees would be at least 280 degrees, and that is a guess based on my observation, I have no proof to back it up other than Autotap logs.

mmm that was on the light side of it and admittedly a bad estimate of the supercharger, this really ranges 10-20deg but I just said 10. The fact is true though:

1 psi boost increases supercharger air discharge temperature 10-20, depending on supercharger type

Thats from www.Kennebell.net
