New dyno numbers at 15.5 psi / T-76 / 347ci Well I finally put the car back on the rollers on saturday to just do a quick pull and see what would happen on my medium boost setting. I left it really rich for the time being on 15.5 psi with a mix of 91 oct and sunoco 104. I will lean it out later when I get more time, oh well it's just dyno numbers anyways. 
My car was freaking out the dynojet weather station so it was giving me high unrealistic SAE correction factors so these are just uncorrected numbers. In AZ your SAE corrected factors are pretty much always over a 1.0 because our air sucks here even in the winter time but I would bet it's really close to 1.0 when I ran the dyno. At first it came back and told me I made 910 rwhp which I knew was both theoretically and mathematically impossible for this engine at 15.5 psi so I turned off the correction factors. Love the power curve on this setup, so much goodness between 3800 and 6500 rpm. For more details on the setup visit my webpage.

Thanks guys.
Mecham, I only turn on the water pump when I am racing as well otherwise it would get on my nerves. That video directory has some pretty old school videos in it, I just looked through it and laughed at a few of them.
a05c, yea you could say it was a bit on the rich side. Snuffs the numbers a bit.

i bet its a blast to drive, when i get my LS1 car here eventually.. i plan on going turbo with it. the people around here use nitrous and i personally dont like the idea of using nitrous as a primary powera adder (personal preference).

Pretty much all the information about my car is listed on my website. I am running a textralia twin disc clutch for now. The motor has just a stock LS6 intake manifold, Ed Curtis custom reverse split, AFR 225 heads, stock AFR dual springs, 15 deg of timing up top.

great numbers nick. i saw your post on azfba but didnt have a chance to post up.
Looks like your 15 psi and my new 101 oct setting tune should be a good match... you prob got 600 lbs less on me but ill prob be about 50-100more hp so it should be good
