what will i need

[pimpdout98gt]

to get my npi headed stang past the 400 rwhp range? without porting my existing npi heads or purchasing and installing pi heads. i need all the info, tips, suggestions, basically any info you guys can offer me. oh yeah and without adding nitrous or opening my motor whatsoever such as boring and stroking my block. if you need a detailed list of my mods let me know. thanx

The only thing you can probably do is get a supercharger but I don't think your gonna get 400 rwhp. Your better off doing a PI swap with some nice ported heads and nice cams with a tune. But your not looking to do that. Honestly there isn't much you can do.

 

[Marvin97]

So you want to get 400rwhp without any headwork, and without a poweradder? Motor swap is about the only way then. You gotta be realistic man, these cars stock don't make half of that to the wheels, and most of them you wee with ported heads and cams do good to make it to 300rwhp. A poweradder will get you to four, but not with npi heads. They just don't flow good enough. Why don't you want pi heads?

 

[pimpdout98gt]

well i do have a supercharger and raised compression. i just want some input on how i can exceed 400 rwhp without porting my npi heads or installing pi heads. i have every bolt on imaginable on my mustang. i just want to know what i need to do without messing with my heads, nitrous or cracking my engine open. thanx

Its good to dream

 

[rick focks]

a full pi swap with a low mileage engine and maybe 12psi should make you happy

He doesn't want to open the engine. And without opening the engine, it's not going to happen.

 

[rick focks]

no no, i mean a full swap out, should be a lot less complicated than a npi to pi swap... i dunno? that sounds like a tall order to get an npi to 400, boost the mess out of it?

 

[pimpdout98gt]

how much boost do you think i would need to make to reach my goal? i have exhaust and intake mods along with cams.

 

[rick focks]

i couldn't wager a guess??? neone???

what kinda of cams do you have?

 

[EastBayStang98]

Its good to dream

LOL.... no doubt

 

[justinschmidt1]

hmm..you would probably only need like 18 psi to reach 400 rwhp with your setup....

you would throw a rod through your hood the first time you got on it but it would be cool

The amount of folk who only care about numbers and not actually using them is pretty large. i think he'd be alright lol
