I Just got my car tuned today and we managed to safely squeeze 516 RWHP out of my C5. I was Very happy with the results...especially for an automatic!

Mods:
Procharger D1SC 6lbs
Kooks 1 7/8 in Headers and ORX
214/230 600/575 118 Camshaft W/ Springs and Pushrods

I think its doin Pretty well...Yella Terras, Fuel Pump, and a Fast 90 are next...We will see what happens!!!

Put some boost to it...You arent going to notice much out of the yella terras...No real need for a Fast since it is Forced induction...Not worth the money spent in my opinion...Good luck

Dont waste your money on the fast setup and sell the YT rockers. That right there will put you within reach of a built bottom end. Then turn up the wick.

Congrats buddy & it's time to have forged Bottom End to feed her with more boost

There is a couple of guys from G-force with stock bottom ends with a D1 making 650 to the tire very safely....Marc Johnson is one he is tough on stuff too...Just a thought...

i don't know of any way possible to "very safely" harness 650rwhp on a stock bottom... in my opinion thats just asking for it

Sweet! Chuck and the HPE squad are indeed cool peeps!

Chase SS if you have plenty fuel and no detonation you would be suprised how they will last. When you buy those parts have someone tune it and see what happens...

I got it a month ago or so...

UPDATE! UPDATE! Yesterday we did a fast 90/90 and 65lbs injectors and we got 546RWHP through the auto! Im happy with it. Its ectremely driveable and it flies! Makes power all the way to 7100 RPM's!!

Yella Terras go on Friday and some more tuning to see what we can do! Chucks the man and LS1's are the Shiznit!

Congrats!!! I dont have a CLUE where people get the idea that stepping up to a FAST 90/90 combo will not be a good investment with any type of forced induction . I've had friends who sprayed and supercharged with LS6 intakes and then stepped to a FAST 90 and had the same results as you and sometimes more. I have yet to spray my 90mm FAST but I'm expecting, huge gains over the LS6 intake. Waste of money?

Amen To That!!!

A FAST intake will always benefit forced induction (unless the boost breaks it open). If it's worth 20 rwhp gain on an NA motor, then it will be worth 40 rwhp gain at 1 bar boost. Those who say just turn up the boost don't understand forced induction well enough. Boost is a measure of restriction. A FAST intake will increase the AIRFLOW into the motor (more cfm). More airflow means more hp with less boost. Less chance of heat buildup and less chance of detonation.

FWIW, Rick from AFR has a C5 automatic that makes over 650 rwhp with a D1-SC. That's a lot for an automatic with a stock bottom end running 91 octane. His secret? Airflow. 72cc AFR 225 heads and a ported FAST intake. Those who say ported heads and ported FAST intakes are worthless mods for forced induction need to go back to school. Airflow is airflow. More is better.
