Power question

[19fobra95]

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.

Probably around there..

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 have a set of nitto drag radials. and high 12's are ok for now since im only 17. lol

Dyno it and find out. E-dynos aren't very accurate.

i am guessing around 285 and 315

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.

ok thanks guys. what would you suggest underdrive pulleys or a short throw shifter as my next mod

 

[BlkoutGT]

Shifter!!!!!!!!!!!!! the stock one just plain sucks.

thats what I was thinking but i cant decide between a mgw or a pro 5.0

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.

 

[sbr420a]

agreed

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.

eventually yes i am going to get it dyno-tuned and I do not have gears yet. Next spring im putting in some 3.73's

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.

what is the short block info and what kind of ring seal does it have?

Its just the factory 302

I am putting ported and polished aluminum made by holley (not sure the specs). is it worth it to port my trickflow street heat intake.
