My customer wanted big N/A power without cam surge. We suggested a set of WCCH All Pro Heads and a small cam. The results speak for themselves.

We have found the limit of the stock LS7 Intake as Manifold Pressure would drop as low as 93KPA above 6200 RPMs. I also have a set of 2" Kooks on order that we will test next week.
And for your viewing pleasure a couple of dyno pulls!
* Was the 93 KPA observed on the stock intake or the ported intake? Is there a CAI and ported TB on the car?
* Why was a big split selected for use on a car with headers? After porting the heads, is the exhaust that far behind to need such help? Especailly with the 2" headers going in could some exhaust duration be traded for intake and gain more power while keeping the docile nature?

Intake is ported. Stock TB with a Vararam.
All Ls7/Ls3 style heads require a bigger than normal split. Due to the huge intake ports and small exhaust ports.

Nice build! The numbers look nice!
And your absolutely correct about the LS7 intake, they leak air like a sieve. The new LSXr intake manifold will be a great product for this car once its available.
