I have a 1995 Gt 5 speed and I am in the process of putting in my new h/c/i combo and was wondering what kind of rwhp I will be at. The h/c/i combo is Holley aluminum heads ported and pollished, stage 2 cam, and trick flow street heat intake. The car currently has bissani equal length headers, mac off road H, and cold air intake. I was thinking somewhere between 300-315 rwhp but I have no clue so i would like to know what you guys think.

It'll be around there with around 325rwtq. The most important thing is that with a set of stickies and a good driver it's good for a high 12 second pass.

i'm thinking the range you're guessing is gonna be the higher side of the spectrum. Remember though it's better to have higher average power instead of high peak power.

Are you planning on getting a dyno-tune after the HCI install is done? I noticed a great difference in drivability after my tune,
and my A/F ratio was WAY off before the tune. Also you didn't specify if you had aftermarket rear gears in the car, if not, THAT
should be your next mod after the HCI. Go at least 3.73, and never look back.

I think your a little high on your estimate hp but it also depends on which dyno you go to some read higher than others.

After the HCI install, if your A/F ratio isn't pretty close/a little rich, you could be running lean all the time and eventually
lead to possible engine damage/ head gasket failure (ask me how i know). IMO, you should budget for the tune along with the HCI,
that way you know the car is good to go, and you won't have to worry about it.
