408 L92-L76 results..
As mentioned previously... Iron 408, stock casting L92 heads, REV valves, L76 intake, 36lb. inj, NW90, 11to1, Kooks 1 3/4 LT's w/cats, 3.73, Textralia, LSK 231-235 110+0 in my CTSV.
First pull the pilot bearing decided to shear itself in half vibrating the bleeder shaft loose and pissing all my clutch fluid out. I had a extra clutch with me, pulled the car off the dyno and started the teardown to see what happened. 2:00 a.m. the car put down... 480rwhp / 472 rwt. It's very smooth, has TQ everywhere and pulls very nice up top. Peak power is @ 5,900 rpm, dyno pulls started @ 2,500 rpm and come up at 420 rwt, 440 by 3k, 450 by 4k, peaks around 4.4k at 472. Excellant package for a inexpensive L92 build up and a heavy car like my V. I think this car is making excellant power for the small cam and inexpensive head/intake package. The heads will be portd down the road along with the intake to see what's left.
Charlie: THANKS for hanging out!!!!!!!!!! Andy, thanks for the lift!!!!!!

But I'm betting you would have made more with your old set of AFR's

Wow, looks kinda like the Captain Torquemaster dyno. A little hard to compare because your's is a dynojet and the CTM dyno was on a Mustang. Regardless, you're on to a new trend. Thanks for sharing, especially after the clutch carnage. Great job Chris.
