Its the knowledge of knowing how to make changes to vvt throughout the powerband. We attend many siminars giving by GM tuning experts.

Not sure how you calculated 533tq. I would guess that The motor tq is below 500. Either way, the time slips show that the power is there!

Does L99 drivetrain loose 20% or not? Even if it didnt 427RWTQ is alot to comprehend from a bolt on car. Your night fury cam barely produces more than that. Is it this way because of the type of converter locked or not? Trap speed looks fine for RWHP, not questioning that.

The night fury in an auto produces about 460rwtq. Pretty big differance. Not really sure what you are wanting me to explain. The combination works and the car flies!

I can see this on a locked converter. I tweaked the vvt on my setup on the dyno with just bolt ons and saw some gains, I put down a max of about 395-398 rwtq unlocked.

Two Questions

Quote from Lethal Racing

This is a customers 2012 L99 that we were happy to see him run awesome times with. He brought it to LS fest and went 12.0 with these mods and last night at our local track he went 11.94 with these mods only....

Lethal Racing dyno tune- with the knowledge of vvt tuning!
3200 stall
Pipeline cai
Ported tb and intake
Full exhaust.
Front skinnies and 18" drag radials on vette rims.
That's it!


What is knowledge of VVT Tuning? Does the automatic L99 Camaro have VVT.

Also, no offense to OP, but his times considering his mods seem slow.

I mean, I thought these cars ran high 12's stock.

I am new at this so please forgive seemingly stupid questions.

Really depends on track prep and DA, just look at the fastest bolt on only L99 11.52

Yea that was over a year ago. That same car had knocked of a few tenths more. Very few l99 can get these times with the named mods. In 2012 it was one of the first to do so.

for the hand full that have run in the 11.'s there are tons more that have not. This is great performance for bolt on cars!

No problem. Most stock L99's run mid to low 13's bone stock. Driver mod is a big part of getting good time

A lot of full Bolt-on's car could run in the 11's in the right conditions and with someone with racing experience at the wheel!!

What do LS3's run stock, with a good driver?

Also the Variable Valve timing, do the L99's or LS3's have that.
