That is pretty much the same conclusion I have reached in my years of experience modifying the GLHS; low 13's or high 12's is cheap and easy with bolt on mod's.

When you port a head and the manifolds, then add 3" exhaust you drastically change how much air is going through. Without +20s my car really ran rough even on a stock injector cal. The stage 5 FWD cal can have more fuel too with the same injector. The MP cal has less fuel for a hotter running engine, so a custom cal with +20s is going to just use more of the injector. A GLHS is an easy car to make fast, starting in the mid 14s stock 13s are real easy. Anything faster than 12s and the money starts getting dumped on them. The difference between the 11s and the 12s is amazing money wise. Since +20s work with a stock cal and porting, I am going to try +40s on a +20 cal made for a near stock engine after I bolt on the bad 655 head =) Rob > > Date: Wed, 21 Mar 2007 08:26:13 -0400 > From: "Bigness, William" <[EMAIL PROTECTED]> > Subject: RE: SD> +20's in GLHS - What else is needed? > > Pretty much the same way I've got mine set up, except I run a mopar > stage II computer with a zener diode installed, which by luck idles fine > with the +20% injectors.
