What gains might I see?

[jhein2580]

So I was wondering as most of us do what should I expect for HP gains if I was to add some AFR 165 or 185 heads to my current set up.

1993 Cobra
Long tube headers
H-pipe
2 chamber mufflers
3.73 gear
underdrive pulleys
flex fan
Crower cam. 15915(Mild cam) .443 Intake .452 exhaust 112deg lobe center

Last dyno she made 275 RWHP and 300lb/ft

What do you think new heads would make?

Thanks

I am trying to figure out how you hit 275 rwhp with the your current combo. Your car must be a freak.

Anyways, my car picked up 40rwhp at the wheels when I swapped out my iron GT-40's for a set of AFR 165's

I can try to attach the dyno sheet if you would like? It was a DynoJet so from what I hear the Dynojet does read somewhat high if compared to a Mustang dyno? If she is a freak then I guess I am just lucky to have her.

Not doubting your word, you just have a great combo there.

I'm not sure I'd touch a thing on that car.

Just get them Jason, you know that they will make good power! Of course you need new tires, and what about your suspension plans? All it takes is money!

Oh yeah BTW, He needs heads so he can beat me again. :-D

Right now we are door to door with my 05 Legacy GT (Stage 2), until 5th and then I say bye bye..
