mods in sig, but mainly the TR224/224-112 cam, ls6 intake, hooker LT/ORY/catback, on 12 bolt w/4.10s(i know it eats a little HP...)

does 34x (i think 346) sound low? just got off phone with them, they said it runs great/etc, but at idle its a little messed up, but then straitens out...


o yea, its a mustang dyno also... he said hes guessing it would be 370ish on a dyno jet... maybe its right, but most ppl use dynojet?

thanks

Dude, that does seem low. I know the mustang dyno brings it down but, I would figure at least 400hp with your mods.

 

yea thats low for sure. I'd agree that you should be around 400rwhp...

 

No way 400 RWHP, If you had heads also then yes but not with just a small cam. Check my sig for comparison.

 

I think that sounds about right. You might have another 5hp hiding somewhere, but I wouldn't expect to see any more than that. You have to remember it's a Mustang dyno (assuming it was loaded during the pull) and you're spinning that 12-bolt. Through a stock 10-bolt on a Dynojet, that cam (with supporting bolt-ons) will usually be about ~380ish. The only time I see those cams in the 400's is with a set of heads.

 

Rule #1
You can't compare one dyno's numbers to another.

Rule #2
Dyno numbers are for bragging rights. How does it run?

Mustang Dyno's show lower numbers. 370ish whp from a Dynojet with a 224 cam only is right in the ball park. 400whp (cam only) requires a larger cam in excess of 230 duration. BTW, that 12 bolt will eat some hp on a dyno, but w/4.10s it'll more than make up for it where it counts.

 

kk thx all!

 

That's really close to my setup and I only made 367rwhp, 372rwtq. That's with a lid, pacesetter LTs, TSP true duals, small cam, and tune. Cam is a Bullet custom grind 224/228, .578/.578.

 

Mustang dyno shows about 8% less hp than a dynojet.

My combo only shows 400 with the converter locked on a Mustang dyno. but I run 120mph in the 1/4 @ 3450 # raceweight. And that's what counts.
