I'm asking this on behalf of a buddy of mine, I have my guess but who better to ask then the guys who do this everyday. He owns an auto '96 mustang GT which at this moment has SLP x-pipe, lightweight driveshaft, catback and 3.73s. His engine was rebuilt right before he bought it 2 years ago and the tranny way rebuilt sometime after that. He's about to put some PI heads from a '00 GT and also add intake, throttle body, plenum, throttle body spacer and pullies. Now he thinks he will put down about 290-300whp and around 310-320wtq. What do you guys think? Any guesses?

Short and sweet:

'96 auto GT+3.73s+cai+throttle body+plenum+spacer+PI heads+X-pipe+catback+droveshaft+pullies=???whp and ???wtq.

^good keep it coming guys. My guess which I forgot to put in was 245whp and 285wtq. Also this in south florida where its always hot and humid, no nice 40-50* weather here.

mrtstang

240-250 rwhp and about 280-290 rwtq

have the heads been ported and polished? is he using stock cams? does he have longtubes? from what you listed, id say he'll make 340rwhp, but aboslutely not anymore than 350rwhp w/o longtubes

So is he getting the PI intake manifold or no??

I'm going to say 235 rwhp and 270rwtq

I like to make my numbers low

You mean 240 and 250, right?

Gears add nothing.
CAI maybe 5
pullies 5
TB&P 10
driveshaft adds nothing (okay, less rotating mass may help rev quicker but I dont think it will add any HP at least nothing noticable)
With the PI swap I'm gonnna give a wild guess at 240 at wheels plus other mods I'll be the very optimistic one at 255 to 260 max.
I hope he gets a dyno sheet.
The horsepower is right is always a fun game show.

230-250whp being generous
