sorry to ask, but i'm in a major hurry...

What should i expect to run in the 1/4 with an 87-89 TII with a 3" exhaust, intake, and pushing about 12 lbs. of boost? what kind of power rating would that bring?

 

depends on whether its 87-88 or 89... but i'd say low 13's, high 12's if you hook up...

 

thanks alot for the speedy input, any ideas on the power anyone? what about at 10 psi?

 

id say high to mid 13's............ w/ no fuel mods..... fcd (which im sure you have since your boosting 12 lbs.).. but for us to give you a good estimate, you have to give us all your mods.. not a few of them!

 

also.... s4 or s5???? big difference

 

s4... this is for future refference. i'm thinking about buying one... I'd put a 3" turbo back exhaust, intake, and up the boost to 10-12 psi. And i'd do any fuel mods nesscesary to safley and efficiently run that much boost. If you'd like to list those mods and their approximate cost, that would be great.

 

you'll need a fuel cut defenser (about $100)... boost controller ($75-500), walbro 255 fuel pump ($100)....... port wastegate ($20 parts)...... aside from the intake and exhaust....you should be good for 230-250 hp...... and low 13's to high 12's...... with the right driver

 

that's exactly what i wanted to know... thanks alot. (i'm guessing that's at 12psi) what about 10? and that's at the rear wheels, right?
