Had a great day. AJ rode over to the dyno shop with me and Curtis met us over there. Got her up on the dyno and made my first run. I had the jetting perfect. He was very experienced in drag racing and tuning and said don't touch the jets. I then added timing a few times, bumped the rev chip, and removed the air cleaner. It really liked the timing. I ended up with 41 total and just couldn't go any farther on pump gas. It wasn't detonating but it's loud! I wanted to

He said the air here sucks and I'd see 20 hp and ftlbs in Cali. My favorite part is 497 ftlbs at 3800 rpm!!!! 491 horse doesn't suck either. Very happy with the performance. I'm sure it will be asked.

Man that dyno vid sounds awesome!! Nice numbers too... so with a 15% estimated drivetrain loss for a manual, you are at 587 crank hp. Is that what you figure?

Also, what octane pump gas you have there? 91 or 93?

It was fun man. The engine dynoed at 593hp at 6000 and 587 ftlbs at 3700. 91 octane Chassis dyno definitely backs that up. It calculates to 17% drivetrain loss on HP and 15% on torque. With our really dry crappy air he said it was right on the money and it was a great motor.

Thats BAD ASS Todd I heard the guy in backround say 491 497 I would have had a smile on my face that you couldn't take off with a chisel

Wish we would have had a little 100 Octane to throw in it...bet we could have broken 500hp easy!
