Default New mods!

I'm getting my headers soon and ported TB. My mods on my car are GMMG, FTRA, Lid, and ones going on are, ported TB, MAF, pulley, LS6 manifold, LT's, and a catted Y + tune. How much RWHP do you guys think I'll put down? My goal is to be in the 12's and i wanted to know if this would do it.

You want a cookie?

Anyway, probably in the neighborhood of 330-340rwhp.
A good driver can drag an LS1 into the 12's right off the lot.

"rated" is the key word in that sentence. I believe that it is more of crank horsepower instead of ground horsepower.

He meant 330-340 REAR WHEEL. Which would be in the neighborhood of 30-40hp gain. That's not bad IMO.

That number, along with 305hp for z-28's, means nothing. They have an almost *identical* motor to the LS1 vette, which is rated at 350. Starting to see a problem here?

They all make about 350-370 at the crank from the factory, give or take a few.

350 hp was a marketing tool used by GM to promote the Vettes.
