Frightening. Not for viewing by women and children.

Did you lose power with a cam with overlap like that? I want to make mine lope but my understanding is due to the overlap you lose boost pressure.

Everything Lingenfelter sells for it but with a bigger cam. Ragin Racin ZfoRce1 cam, LPE 14% balancer/2.38 upper pulley, Katech heat exchanger, LPE cnc LS9 heads, LPE snout, LPE air intake, American Racing headers(no cats) and some extra port work to the blower base.

No dyno #'s yet, working on idle and startup tuning first.

We will be switching to a 102mm throttle body once we get the numbers using the stock one.

Keep us posted on the 102 TB.

It look like it's more of a headache then anything for now.

Sounds great. Cam may soung big, but it only has an overlap of "7". Many cams out there are much bigger than that. It's on the edge of sounding great, without bleeding off too much boost. Well done.

Wouldn't positive overlap period bleed off boost. I was calculating the stock one yesterday and it's at -24.5

Very true, any overlap will bleed boost, but 7 degrees is minor. The stock cam has everything built into it; mileage, emissions, power/torque and driveability. We are only concerned with power/torque and a bit of driveability.

We are dynoing today, so hopefully have some preliminary numbers soon.

Why is everyone picking on my POS? We cheated remember I had the exhaust off of it...lol. If we are the bullseye, can I get some royalties for every shop that has a ZR1 come in for some mods?

By the way, love the new avatar.
