Expected H.P.?

RedHotFox · May 11, 2011

Hi guys, I have a 1990 Mustang GT Convertible with a 5 speed. It currently has a stock engine and tranny with about 30K miles on them. The mods include FRPP 3.73 gears, BBK Cold Air, Mac Shorties, O/R H-pipe, Flowmaster Catback, MSD 6AL Ignition. Screamin Demon Coil, Comp Cams Powerbox Upper Manifold, and Underdrive Pullies. I am about to purchase GT40P heads and an Anderson N41 Cam. I am wondering what kind of power I am looking to get with that setup with a proper tune, injectors, maf, etc. You can post here or email me @ caleb_b_2008@yahoo.com

Thanks guys

That's what I'm hoping. I expect around there, but I just figured I'd get some experienced input. Thanks man.

Maybe 270, 280rwhp, if you are lucky!

260's or less
I wouldn't expect anything too good with that intake, especially if it uses the stock lower intake and not the gt40.
Realistically it's not the right upper for a low hp engine.

I have gt 40 ps I have 275 at the wheels.. Similar supporting mods.and tuned

I guess 240 at the tire. If the dyno says 300, id say its a really optimistic machine

Use the explorer intake. It's much better than the stock unit. That's what I am running.
