LS3 C6 makes 527 rwhp! A copy from my thread on corvetteforum: After months of research I finally pulled the trigger on doing a cam swap. Plans for the car were an occasional drap strip visit, but mostly street driven/DD so I didn't want a car that would barely run. I contacted MANY vendors(most if not all on this forum) as to what they would suggest. I turned to Vengeance Racing for there 'stage 3' cam package that really interested me. The package included everything you needed to do the job properly. I went ahead and installed new lifters (LS9) as I had the resources to remove the heads while I was in there anyways. A coworker who has been in the porting business for many years took my heads on as a challenge. He noticed right away that the runner didn't need much work, if any. The rough casting would be smoothed, but no excess material required removal. I also spoke with Cajun @ Bare Essentials Racing for a ported TB, and intake manifold. Mod list is as follows: VR Katoik camshaft - 235/243 620/623 113 LSA VR Dual Springs Hardened Pushrods - 7.400 MELLING High Volume Oil Pump KATECH C5R Chain COMP Trunion Kit ARP Cam Bolts LS7 Timing Gear LS9 Lifters LS9 Spark Plugs Ported Heads OBX 1 7/8" headers Catless Mids Corsa Sports BER Ported TB BER Ported Intake Manifold Dyno Tune by Walls Rod & Custom. Redline set to 7000. The graph printed wasn't the car's best run, but was very close ~ 2 hp. Our best run, the car made 527 rwhp and 436 rwtq. I never got the final AFR ratio, but later I added a AEM wideband and afrs are around 12:1. Nonetheless, hat an animal! Big thanks to Kevin and Ryan at Vengeance Racing for all their help! As well as Cajun at BER for his assistance as well. Top notch vendors. http://i302.photobucket.com/albums/n...ide_mb/IMG.jpg http://i302.photobucket.com/albums/n...b/IMG_0001.jpg Idle clip(car was cold and literally was running on fumes so I just did a quick light rev): http://i302.photobucket.com/albums/n...h_IMG_0884.jpg |

Damn, that's stout on a Mustang. That's about the high end of expected on a Dynojet. Am I missing something? |
Wow...that thing is making some good power! |

Having 350 ft lbs at 3k rpm should be pretty nice right? I would guess (cause I'm no expert) that this car would rip pretty well! Especially with it's relatively low weight. |
I hate when they format the graphs like that! Not too shabby on power though, peak torque is a lot higher in the RPM than usual. |
What would SAE Dynojet numbers be? |
Very impressive #s!!! Thanx for posting |
Very impressive numbers on a mustang dyne!! Dynojet SAE would be around 540whp! |
Now I know what my next car will be |
damn thats good power. |
That's what I'm talking about. |
Nice numbers.

Thanks for the comments guys! Car ran 12.2 @ 123 on stock size street tires. Looking for a low 11 next year with drs |
527rwhp and only 123mph??? What was the DA? Auto or Manual? |
Putting the power down with street tires is near impossible. With DRs I'd expect you to pick up at least 5mph or more. |
