Default 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!!!!!!

I'll try and get the graph up today, I have not gone out to the car yet to see what I printed, my wife is always thrilled when I stroll in at 4:30 a.m.

SAE and SD, thanks for the typo, corrected.

VERY nice build, love it - look stock, sound mild, go fast, be reliable. NICE NICE NICE. I too would like to see how much acreage under the curve you have. Good job!

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.

They dont, but i guess they can make custom ones, that would cost more money than the others. i dunno.

I just got my stock ones from SDPC today. they look pretty good.
