who here is making 475+ whp on pump gas. Not e85, strictly 93octane. Specifically what turbo are you running, whats done to the head, and last if anyone is making 500whp on the stock sleeves and pump gas....

 

bump

 

i would also like to know

 

I made 468whp on pump gas on 18.5psi with a 84.5mm bore ls/vtec. Head ported by me, gsr cams, hp racing intake, stock tb, and my custom ramhorn. Turbo was the blowzilla .63ar hotside. I'm sure with better cams/tb it wouldve made 500 on pump. Not to mention I didnt do that great of a job on the head, whoops. But this year i got a top mount, made by me of coarse, gt4202, professionally ported head, maxworx cams, and 85mm bore. It will DEF make over 500whp on pump...stay tuned

 

Stock sleeves and 500 WHP on pump gas? Not safe unless you're spraying meth, IMHO.

It's a ******* waste anyways. 425 WHP will burn the tires off just the same as 500 WHP.

 

last weekend my car made 478whp on 20lbs (mustang dyno) on 93 octane from UDF.... stock sleeve b18c1,cp pistons, crower rods,ctr cams, valvetrain, sc6176e, AFI ramhorn, 3" open dp, etc....

 

500whp wont roast mt et streets in 4th gear IMO... and those are the tires i run...
