05 ls2 on the dyno
So I put the vette on the dyno after cam and header install and wanted to see what you guys think of the numbers it put down. The vette is a a4 with 3.15 gear custom grind cam and kooks and the numbers are SAE corrected
stock
335 hp
322 ft lbs
after cam and kooks
414 hp
392 ft lbs

OP: Congrats on your new found power, for your next mod look at a Ported Fast 102 Intake Manifold, they are great for the LS2 - http://forums.corvetteforum.com/c6-t...st-intake.html

stock numbers where very disappointing.... I've done a g/s body to the car so every time I took it to the track I had a ton of people asking what was wrong with the car for it only to run 12.9 all I could do is laugh and say its a 05 with a 6.0l. I'm gonna take it to the track tonight and see what she can run now buts it 100 outside with 95% humidity so we shall see

Those figures are nearly exactly what I obtained out of my LS2.
Here's where I went from there and the path I took.

Decided yesterday to overlay all my mods since I've self tuned and dyno'ed each time I did major mods.
I found it interesting and thought I'd share.
See below. Each line represents progressive mods:
1. stock;
2. headers & tune (3.90 gears at same time);
3. G5x3 cam & .040 gaskets (11.4 compression);
4. FAST, and
5. used AFR 205 heads.
What strikes me is how dramatic the gains from headers and a tune were. Combined with the gears, it felt like a different car, and I got a full second + 10 mph in the 1/4 from those mods, from 12.9@108 to 11.8@118. The car was dead nuts reliable at this level.
The second take away is how all the remaining mods really only mattered from 4500 on. Thus I very seldom notice them on the street, only on the track. Not counting the cool sound of the cam.
Mods 3-5 did take off another second and added 10 mph - to 10.8@128. But it cost a lot more and I broke a diff and two transmissions on my way.
This graph shows what I've been saying for while; headers, tune and gears give you by far the best bang for the buck from idle to redline, the remaining mods only matter from 4500 on. Most street driving is below 3000 rpm...you do feel gears and headers even at that level.
Hope someone finds this useful as they decide upon mods.
If you are drag racing, you can expect .1 to .15 from putting skinny tires up front (saving 50 lbs+ of rotating weight) and taking out your passenger seat (53 lbs).
