257/298 justa wild shot

 

[zeevann]

my goal is to get 260 outa her, im hoping i have a stronger than usual engine

If you got a 3" Catback system that's wayy to big. Or just 3" tips?

 

[zeevann]

just 3 " tips

Yeah you didnt mention.....PI heads? I sure hope so and do you have a converter in there yet or not?

 

[cobra2798]

I have almost the same set up( minus TB/Plenum and mines a 5spd) so im interested to see what you put down, please post the results ASAP.

if its still npi heads i will say 243rwhp 272rwtq. hope im wrong but just being realistic

Since it's an auto, I'd guess right now about 235/265.

Let us know what we win!

 

[mazen189]

220hp/270 tq

 

[02nightmaregt]

Seems as though ive overshot Didn't notice the npi heads

 

[Silverstang02GT]

What dyno is it? If it's a mustang Dyno I'll say about 215 - 225rwhp

 

[98COBRA281]

my stock npi with very simalar bolt ons put down 225rwhp, 270rwtq with a 5 speed..............

 

[Crzyhrse]

Seeing as a '97GT was 215HP stock, and then you have an Auto to boot, your lucky to be putting down 175RWHP stock. I doubt your mods are worth 85RWHP. I'd have to side with the people saying in the 225RWHP range.

i just saw a stock 01gt (with a cat back and cold air) pull 230 when i had my 97 gt with a cat back pullies and a cai barley pull 210 thoes non pi 4.6s are the black sheep of the mod motors im just giving you an idea i think youll probally pull 220 outa it (dynos are dissapointment machines)
