3 inch x pipe that necks down to 2.5 right before the connection to the stock titanium exhaust.

Very nice. I have an '03 z06 with similar results and a very different way of getting there. I was working around California emissions. I think this is a pretty cool comparison! This graph is on 91 octane. I was able to pick up about 12 ft lb in the low range on e85.

What really surprised me is how down on torque I am compared to you at lower rpm. Damn long tubes and no cats are working well! I feel like the dual 3" is taking away some low end power from me for sure, but the convenience of a nearly bolt-in x-pipe won me over. It's a nice 304 stainless x-pipe from Corsa too and the car sounds amaaaaaaaazing compared to stock.

AFR 205 heads w/ 62cc chambers
SLP 1.85 rockers (600 lift with stock cam)
Smith Bros 7.45 and 7.50 pushrods
Ls7 exhaust manifolds and cats
Corsa 3" x-pipe mated to OEM titanium axle back
K&N intake
Ported throttle body
160 thermostat and a good tune

Amazing how the little LS6 camshaft does so well.

AI emailed me this morning... should be getting my heads within a week. Anxious to get her back up and running and see where I'll be at. Once I get the tune sorted out (I do my tunes over email) I'll be heading back to the dyno!

Yep, been 10.0 and 135 in a bolt on (SI) ls6 in a c5Z.

I saw you said you wanted around 450 with heads and cam so I thought I'd share my results. I achieved the below with stock heads, intake, throttle body and tstat. I know aftermarket heads set the next level for future upgrades, but I got close with the stock 243's.

447 rwhp / 406 rwtq.

Mods: Tick Performance SNS Torquemax Stage 3 cam, Brian Tooley .660" lift springs and titanium retainers, SLP 25% under drive crank pulley, Airaid cold air intake, Fast 36lb injectors, Kooks 1 7'8" Long tube headers, 3" X pipe no cats connected to the stock titanium mufflers.

Going to get the car tuned here in a week or two and then hit up the dyno again to see where I'm at. Had to make a quick idle and rev video.

Car is almost tuned up. WOT stuff is spot on. Going to hit up the dyno again next week once I'm back in town.

aaronc7

New results are in. We'll call it 435hp/400tq. Here are some graphs I made showing before vs after.

New stuff:

AI 226cc cnc ported 243 heads, milled ~0.030", stock valves with PSI 1511 springs.
PatG specced EPS cam: 226/230 .604/.604" 113 +3
Remote tuned by PatG via Autocal

How does she with the new heads?

2003 Z06, LG headers and catless X pipe, Vararam intake, stock over the axle and street tune. A/F was set at 12.8 for track duty. This is SAE(corrected), uncorrected it made almost 400rwhp.

Nice man. You run out at NOLA? I have my first event in 2 weeks.

FASTFATBOY

iTrader: (23)

Yes I do, look up some of my Vids on Youtube to learn the track.

I may go to the PCA event on the 28-29th.

aaronc7

Pretty sure I have seen yours before and took another look again last night.

You planning on doing anything else to the vette?

I would like to hit up the PCA event as well, but work conflicts . I'm a good 4 hours away.

I made 391/378 in my 04 CTS-V LS6 with full bolt ons. LS7 clutch, headers, udp, fast 92. More drivetrain loss i know but close.

This torque curve in that car shocks some people, i bet. Nice!
