Close to the same exact setup....
How do you get 30 more ft/lbs at 3,500 RPM's?

I'm not trying to crack on anyone, Vengenance obviously knows what they are doing and have way more experience than I'll ever have, I'm just trying to understand how this car is making that much power. I went with a 228/232 in my LS2 GTO just to get this kind of a torque curve and gave up some topend to do so. This just looks like the best of both worlds and I don't understand how they got it.

Exactly! Similar yes, but not the same (unlike a Mustang vs. Dyno Jet dyno). Just like you wouldn't see the same numbers from two of the same model dynos on the same day. Dyno numbers are inertia, I use the load cell for dialing in VE & A/F, final numbers are inertia.

Congrats man very strong numbers. Its funny how when its done at vengeance the numbers are too high and when its done by some other guy in a shop 5 states away the numbers are still too high. Nothing counts unless you run a number at the track that someone else says is the right one either.

Cecil Country in MD. I believe it is sea level. I will post them after my hangover on Sunday, for a whole new round of fun!
I will also post a idle video tomorrow. Sounds wicked.

Congrats on some truly impressive dyno numbers. Ron told me about your car when I called him from the track today. Hit the track and post the results. They're going to certainly be impressive. Good luck.

This car has 400 ft/lbs from 3.5K to 5.5K approx. with a very flat TQ curve
The other Z06 only makes 400 ft/lbs from 4.5K to 5.5K with approx the same peak TQ and HP figures but the curve looks more bell shaped.
It's just that extra TQ down low between 3.5K to 4.5K that I don't get

Should be a good time on saturday. I am the other car he is running. 03 Cobra (CAI, Magnaflow catback, 2.76 pulley, predator with mile hi dyno tune.... We had a little chance to run on saturday when he picked up the car and it seems that it will be a VERY close race. Cars with my mods have trapped in the 120-123 mph range i believe.

Damn, I think I may have found a good cam to look into. Do you DD your car, have you gotten any good mpg estimates yet, or is it still too new for you to keep your foot out of the happy pedal? Anyways, good numbers, will be watching for updates on times/speeds at the track.

I have not had a chance to tripometer a tank of gas, but you know how you have that period of time when the tank is full before the needle starts to move? Well, it seems to take just as long as before. Hope that helps.

Yeah seriously if everyone could hear that cam in person people wouldn't doubt the number it puts out. It makes my tsp 233 cry and run into the corner...

That cam definitely sounds mean'r Hell. I've got that same cam and love it. When I cranked it up at the track yesterday it turned heads. It's a good feeling. Wait til you go to the track. You'll get the respect you deserve.

LMFAO... We have made 440rwhp 4 times at our shop cam only.... Now this guy hundreds of miles away does it and its not real 
I guess SmokinStorm that made the fake 450rwhp unlocked and is now running 10.70s@126mph with the same camshaft in an A4 is lying also... Along with Brad02Z06 who made over 500rwhp with heads/FAST/Our Vindicator camshaft/ Or how bout Dre01Z06 that made 440rwhp with an LS6 intake/stock heads.... The list goes on and on... but so do the haters

I know better than to weld iron-to-steel- I'm an engineer. I'm on my 2nd generation design. My first was better than yours and still broke. I'm not trying to be rude, just being frank. Also, I started my 8.8" long before you posted any kind of pictures about yours, and I can assure you I did not take any ideas from you.
Anyway, that's besides the point, GREAT job cam-only!

Even dynojet type numbers, 440 Id be expecting 122 at 3600 or a bit more lbs
