500hp?????? dont think so maybe at the cranck but thats it! Also on ur charger you said u run 8lbs 10lbs go in for a dyno run and change it to 12lbs and ull get that 500 but i wouldnt keep it that way untill atleast i got a after or inner cooler. Or keep it at 10lbs and give it a good 50shot and ull get those number!!

I'd say 450 rwhp, I'd look into a set of AFR Heads, but since you've already had everything port matched, your kinda set up for the irons [&:]. You'd have to do a full intake/heads combo swap, I also agree with bumping your boost to 12 psi, as long as boost timing is retarded and A/F is in check. A methanol injection kit, or cooler box, should add a few horse as well. A dyno will be the best way to find out, andyou should have it fully tuned anyhow,whatair/fuel monitoring system areyou using?

Well I have not got it "dynod" because it's a guy who is selling his. I am about 85% sure I will buy his mustang. He said it dynod at 475AWHP so I was just checking to see what you all though.. It seems most say it's real close..

7upedition

what is AWHP? do you mean Rear Wheel Horse Power, or FlyWheel/Crank Horsepower, or is it All Wheel Horse Power?

luckythirteen13

he defenitely didnt make 475 at the wheels with that setup and id be surprised if it made 475 at the crank

It took us almost 20 psi to make 520 rwhp in the R/S car. That was with a stock cam and Trickflow heads and intake. I think your losing alot by using GT40 heads.

500HPCobra

No not AWHP read wheel sorry. If I buy it I will lose the GT40 heads, I just want to make sure this engine is at 400HP or more...

I have large *** valves in my gt's and about 40 hrs in porting..plus cut back valves and just push over 500

500HPCobra

so it's either 500 or very close. Am I reading this right?
