500rwhp L99 brought to you by Lethal Racing!!! - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Lethal Racing · 04-30-2013, 03:34 PM

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

VADER SS L99 · 04-30-2013, 04:34 PM

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.

Jason 98 TA · 04-30-2013, 05:23 PM

Great job guys! Its results like this that shows the PRC aftermarket castings are making some power!!

Glad your happy with it!!

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.

litle88 · 04-30-2013, 07:56 PM

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.
