estimate hp

about how much horse power do you think ill have after doing the following on my 96 4.6 sohc

U/D pullies
TB and Upper intake manifold (C&L, accufab, what do you recommend?)
PI head swap<-- expects most of the power to come from there
exhaust- im thinking true duals or 2.25's to a 3" then split to 2.5's
SCT chip

my goal is high 13's, and i thnk that w/ a J-moded Aod-e, torque converter, and a coupple of other drive train mods, i can get there.

im hoping that i can get 250 rwhp from the mods i listed....

what do you think

BTW, i drive a cougar, it weights about 2 tons w/ driver:eek7:

Ttt

Your exhaust is going to hurt you. A 96 V8 already has a true duel exhaust in 2.25" diameter. If anything I would increase it to no more then 2.5" in diameter, and not mismatch sizes.

i have a cougar- no dual exhaust. i was thinking 2.25 into one slighly more restrictive 3" pipe, for simplisity, then 2.5" for sound...

The 95 V8 has dual to single to dual again.

It is single only through the resonator.

I'll look under mine tomorrow and tell for sure.

Even so, I would not go with different size pipes like that all in the same flow path.

I agree with you Highflow!

so you saying 2.25 for the dual to single?
