Power after these mods?

I couldnt estimate the hp since im not a 4.6 guy but im sure it will fly!

 

Are the heads on the PI motor stock, or have they been ported or polished?

 

i would take a stab in the dark and say you will be putting close to 250 at the wheels with that, but im not sure, you could easily be higher

 

the PI motors usually do around 225-230 with a manual trans STOCK, so with the mods you have listed you should be well over 250. Probally in the neighborhood of 270rwhp I would say

 

I say about 165, similar to what droptop said.

 

165? What ???

 

Shit, I mean 265 :slap:

aaagh

 

PI swap with dyno tune I'll say 240 at the wheels. I did this swap had everything P&P with every single bolt on you can think of. Check out my signature for for info. I haven't even tuned mine yet.

 

you had me lost there for a minute :hammer:

 

The hp is hard to guess but some where in that range will be where you are, closer to the 270 mark I think. With those 4:10 gears some sticky tires and the hp you should have, low 13's will be nothing for this combo. I would be looking to crack a 12.99 if I were you

 

With good cams, P&P and a GOOD tune, I've seen 320 to the wheels on the headswap.

I did mine, Auot trans, Denver elevation, average tune and got 285 to the wheels.

 

I ran 13.2 @ 109 with my setup and some DR's. After I tune it and the ATI gets on my car. I will be looking to crack 11.99. IF I dont then i'll just need MORE BOOST.

 

My buddies 02 gt made 284 at the wheels with:

American Thunder catback
Mac off road X
BBK 70 mm tb
C and L upper intake
diablo tune

so I would guess somewhere around there or a little more with your shorties

 

i'm going to say 265

 

Im going home this weekend, so if he still has the sheet, Ill be glad to get it and scan it to prove it to you
