500rwhp L99 brought to you by Lethal Racing!!!

We get a lot of calls about guys wanting that all mighty 500rwhp Naturally Aspirated. I tell them all that it takes some work to get there. Then when they come in and ask if it can be done on a L99 my answer is that it would be hard to do and maintain drivability.

This board member wanted 500 or as close to it as possible. So we happily went to work on a setup that would make the power and still maintain drivability in his L99.

Here is what we cam up with:
Lethal Racing L99 to LS3 Conversion
Lethal Racing Enforcer Cam
PRC LS3 255 Heads Milled to LR Spec
Prototype 2012 Vararam Cold Air Intake
25% Underdrive Pulley/ 160stat
AR 1 7/8 Headers
Yank 3600 stall
Lethal Racing Street and Dyno Tune

I assume thats a unlocked converter since its a Yank? If so that tells me those heads were probably worth alot more extra power. Really stout #'s. Congrats.

Looks like its a locked converter since they were able to start the pull so low.

I think that he would benefit from a FAST 102/ 102 also IMHO.

Hell I'd send him mine for testing, all he'd need is a 102 TB!

Whats the difference between the Enforcer cam vs Night Fury? Im looking into the PRC 255s with the Night Fury on an LS3. I havent seen that combo yet so Im wondering what the number would look like.
