My tuner carries Kooks, but not their stepped headers. He was very surprised with the numbers he was able to get from my mods (as I was also). You can view my build by going to my garage.

Thanks, those are good numbers.

New numbers on the same dyno I did 389/387 on before are 426 RWHP and 418 RWTQ. I'm very happy with the gains from the headers...I was seeing between 0.5 and 1 degree of spark retard at 12.8:1 and stock spark, and the car was losing a TREMENDOUS amount of torque when that happened...so I fattened it up to 12.5 which it really likes...no KR, extremely clean dyno pull. I'm very happy with the car, it's really running great now.

I added AI porting to the heads along with a custom grind fairly mild cam, a FAST 102 and matching throttle body...499/463 now.

2013 ls3, manual trans, rotofab intake, Livernois motorsports dyno tune. 39hp and 44 torque gain with NO OTHER MODS.
Livernois Motorsports is the shit!!!

Oh, lol, yea bud, talking about him

[thahemp]

I guess it's the power wedge then? Is there a cam on the list that i'm missing?

my baseline from last june (06/18/2012):
381HP/380TQ

stock w/ ARK exhaust & tune (06/20/12) temp: 95* baro: 29.8 hum: 75% :
388.9HP/380TQ

Roto Fab CAI, Vararam PW, LG Motorsports LT's & HF Cats, ARK 2.75" N-II exhaust, 3.91 gears & updated tune (01/04/2013) temp: 46* baro: 30.14 hum: 42% :
441HP/423TQ

no, i don't use ricer math as it isn't all additive from one mod to the next. that being said, there was a noticeable increase with the addition of the CAI, even more so once i added the LT's. LG's headers have been proven in the vette community, and also came with a high recommendation from my tune shop...they produce impressive torque.

the dyno tune included the correction factor, so these numbers are not inflated. believe it or not, these are my numbers showing the progression with the addition of my mods.

out of curiosity, what numbers have you seen with your car?
and who are you comparing me against? if you look back at the previous page you'll see 2 others with numbers similar to mine without a cam.
and remember, not all dyno's read the same and are nothing more than a tuning tool.

I'm comparing you to 99% of all the other posted charts in this thread with LTs, intake, exhaust, and tune. I agree they're just a tool, but you should be between ~395 - 420 HP with your mods. Start on the first page and you'll see example after example of where I'm coming from here.

I haven't put my car on a dyno.

[hapisok]

395 being the low end with all my bolt ons? thats just CRAZY! a good CAI and TUNE is good for over 400 easy. even High Flow cats with stock headers and CAI is a major improvement and should leave you sitting around 415-420. i think i made the right decision when it came to choosing LG headers. as for the Vararam Power Wedge, im not saying it makes a HUGE difference, but its all about fluid dynamics, efficiency, and equal distribution of air to all cylinders...it does help.

http://www.camaro5.com/forums/showth...114824&page=14 posts 343 & 347 just as an example

your more than welcome to dispute the accuracy of the sheet with my shop/tuner...but his reputation speaks for itself. they don't give inflated results to make customers happy, they prove their worth at the track, where it counts.

[thahemp]

I saw those. Notice the "optimistic" comment.

You guys are anomalies. That can mean 1 of 2 things. The numbers aren't quite right, or you got an extreme factory freak.

There is a post in the first few pages from a guy that went to the same tuner as you with a cam making 10 or so more than you.

[thahemp]

Post 129. Even less than 10.
