Default Dyno, 481rwhp

Just back from synergy Motorsports to get my car tuned. I was very impressed with the job Rick did. Thought you might like to see the graph. I also thought many of you might like to see the comparison graph for my much lamented 69 L88 clone. I loved the power of the L88 but I also love a/c, power steering, stereo, etc. I now believe I have almost got my L88 back, at least in spirit.

The Z has an SLP 402 with AFR 225 high compression heads. I am running a 228/230 @ .591 lift on 114 centers, LG long tubes with high flow cats, stock air cleaner assembly and intake.

The L88 was a factory crate motor with all factory internals. i.e L88 cam, forged 12:1 pistons, alum factory heads 2.19/1.88 valves, factory stamped L88 intake and replacement Holley 4 barrel, Hooker side pipes.


Chuck





p.s. I believe I know have as much or more rwhp as the marvelous new ZO6

Very nice numbers especially considering the cam size.

Nice! I have a similar setup. SLP 402 with AFR 225 heads. The difference is that I am running a F.A.S.T. 90mm intake, 90mm TPIS tb, a bigger cam, Kooks 1 7/8" headers, X-pipe, no cats and B&B bullets. Air intake is a massive Haltech.

I am making 517rwhp and 490rwtq. Can't wait to try it out at the strip.

Congrats on the great numbers Chuck! Having had the privilege of riding in both your cars I can say you have a real monster on your hands that compares very favorably with the performance of the 69. I am predicting long black strips of burned rubber in our culdesac and some fun surprises for the unsuspecting C6 Z06s in the area!

I will be available to bail you out any time you need me!

Very nice numbers Chuck. Did Rick do the 402 swap as well?

Pio,
Fidenza alum flywheel with LS7 clutch & pressure plate.

Lewishou,
I would have taken the car to Rick for the engine swap; but because it was on a day that Synergy was closed when I discovered my factory engine basically toasted due to a broken valve spring, I took it to Valaya Racing which was about 20 miles closer. Without raising the rath of others on this forum, can I say that he specializes in Vipers? There were 16 there one day. Even so, he is a great guy and I was very pleased with his work overall, even if there were a few things he wasn't as up on as Rick would have been.

How do you find that clutch? I am running a Spec III and get a bit of chatter so was contemplating this swap.
