"The car is a 1990 GT 5 spd. All stock everywhere, including exhaust.
283 HP at RW before (325 HP at the crank) is now 405 HP RW (465 HP at crank)
275 FtLbs at RW before (316 FtLbs at crank) is now 386 FtLbs (444 FtLbs at crank)
...an increase of 140 HP and 128 Ft Lbs of torque.
Air/Fuel ratio was constant at 11.5:1 Idle 750 RPM steady.
Boost gauge showed about 7 psi at 6,000 RPM."
Z,
It appears that the 90GT was running fine before the SC was installed from the quote above.
Also, please explain the mechanical problems this car has so that everyone will know to look for them. I am sure the average person installing a system would overlook them if you and Carl didn't notice them.
Thanks,
Andy K

If you're going to supercharge your car, make sure everything is mechanically sound before you do it. Remember the discussion about the roughness of the dyno curve of that GT when it was posted? Well, there were a couple of issues with the car that weren't known when the dyno session was done, including the full throttle switch not working. The owner of the car is planning to have some service done on the car, probably in spring. Hopefully he'll do some dyno runs after that's completed.
Along the the throttle switch, it appears that this car was making about 6psi on the dyno based on the numbers. I talked to the owner after it was dyno'd and he said he was seeing about 5 psi on the gauge, so I know the belt was slipping even more as it was breaking in. As I mentioned in the past, I have updated the design of the tensioner to incorporate a self adjusting spring which eliminates the belt tension issue therefore eliminating belt slip. This car should see 8psi with the current configuration.

If the GT were to make the same percentage gain as Don T's car then it would need to make 33rwhp more hp at 7 psi and 56rwhp more at the kit rated 8psi. And for Lags statements to be correct then the GT will need to make even more than that. So the owner should see a minimum of 60-70 rwhp gain if everything Lag, and Z are saying is correct.
So this means that if everything goes correctly with Jim R's system (if he runs 8psi) then he will get a minum of 470-480rwhp. AWSOME.

whats the difference between a 248c and the usual 248e that we all run with out here?
even still, im sure the differences are only 10-15hp max.
