hello all just a question i just installed a vortech SQ blower on my 2001 GT, the GT put out 270 with all my modes, mid tube headers, dragon plenum and 75mm dragon throttle body, 3.73 gears, steeda cat back system with off road X pipe, with the blower installed i got 376.4 HP and 362.05 Torque just installed a boost gauge and at idel pulling 30 inch of vacuum and when i punch it it boost at about 6 PSI or so is that possable with the stock 3'60 pully or am i doing the test all wrong, the car pulls awesome should the HP be higher with that pully? or is that about right BTW i also have the steeda boost pipe installed any input would help thanks.

that sounds like the power that that kit is puttin out. Those numbers are almost identical to about 2-3 others on this forum with the same vortech setup.

I say its good numbers for only 6psi

you can get a boost pipe (powerpipe) to replace the inlet tube. They run like $200 and are supposed to give you another 1-2psi. You can obviously swap out the pulley too, but don't get to crazy as the stock gt blocks are only good to around 400rwhp.

He already has a Steeda boost pipe.

Numbers sound good, great for 6psi - headers and exhaust are probably helping you alot. Peak boost should be between 6-8psi with 3.6" pulley and Steeda boost pipe (it's not as efficient as MPH or AFM boost pipes as its about 1" smaller in diameter, I saw 9psi with 3.6" pulley and MPH 4" boost pipe, now I see 11.5psi with 3.3" pulley).

Yes, you can change the pulley to gain more power - but you have to make sure your tune is safe or else you may end up popping the motor. Adding an intercooler will allow you to "safely" run more boost and more timing to make MORE power, also.

30 In of vacuum, is that right? Mine only does 17 in. Hg. at idle. And I hit 9 1/2-10 lbs of boost with my setup. 413/413 hp/tq.
