I have a 1990 formula 350 TPI w/35k miles....w/ the following mods.....1 3/4 long tubes, hypertech chip, 4.10's , automatic, bbk pulleys, TB air foil and bypass, KN filter.... any ideas what that would run ......then i have a 150hp shot of nitrous express....guesses on motor and on bottle?!?!

 

First of all you're on the wrong board, this should go on one of the racing boards.

Secondly, you better change your torque converter and get a chip made by someone that knows what their doing or forget changing proms.

If you manage to hook up somehow and your car is in decent shape you should be able to break into the 13s n/a, mid-high 12s on the bottle.

I realize you're just into bolt ons right now, but that really isn't where the most performance is made.
