How much HP can stock TB support?

[jaymac]

At what power level will the stocker become a serious bottleneck.
My next mods are listed below; GT40P's, ported, polished, and milled .030, along w/ Explorer upper and lower.

How much am I hurting my potential w/ the stock TB?
Thanks,

J

i think you could probably benefit mid-top end from the tb swap. generally you lose a little lowend though.

im not real good at predicting numbers and that, but i think they become good supporting mods around the 300ish hp range.

i think i read somewhere it flow's 580cfm.
should be good down into the 11's n/a.

depends on your plans for the car on a stock engine a really large t-body like a 75mm would be over kill and crush your lowend and throttle response, I think the best bet is to match it to the opening on the intake you plan to use to avoid a bottle neck.

well, the GT40P's are going on soon w/ Explorer intake , which uses a 65 mm, and after porting and milling, I'm hoping to near the 300 mark.
