I have a 1991 Trans Am 305 TPI 5 Speed w/ 10# ProCharger.

Here are my mods:

SLP headers and 3" exhaust
Crane Cam
SLP intake runners
SLP air foil
SLP High Performance chip
Crane roller rockers
Crane Valve Springs
TPIS big mouth intake
Accel 23# injectors
Racetronix high flow/pressure fuel pump and wiring harness
All new ignition items (wires, cap, rotor, etc)

The car is tuned and runs excellent.

I feel that I can push a little more HP out of the stock bottom end and am trying to decide whether to go with a 50 HP nitrous shot or a smaller pulley.

I feel that the Nitrous shot will help to cool the intake and make for an all around better system.

I am specifically looking at the NX set up which gives jets from 35 HP to 150 HP.

But since I have a twin intercooled ProCharger system I may be able to get the same gains by just changing the pulley.

Also I am concerned about how much HP the engine can actually take. I used a computer program to figure my current HP and it looks like I am at 320 RWHP.

Any GOOD advise would be appreciated.

Thanks.

 

just pulley up, all youre gonna do is break junk when you have to tune two power adders.


just my opinion, dont care if you like it.

I like it!!

In fact I been thinking how difficult it was to tune what I have now that trying to tune the Nitrous with the ProCharger might get me back to day one.

But I still wanted to see if anyone had some actual experience with the combo set up.

Not too much info out there except from a few vendors.

 

exactly, its dangerous if you dont know what youre doing tuning one power adder.

its just dumb to do it with two.


just pulley up, its more fun anyway.
