Any updated results and personel recommendation on supercharging

[Tricky]

Hello Gents
I have been looking through the threads here for a couple of days and I can't seem to find anyone who has supercharged there ZO6 and has had a great experience and would recommend this. All I seem to find is nightmare stories or constant problems. The C5 zo6 everyone had dialed in, I realize that is a whole differnt animal but I would have though someone would have made a sure fire product for us ZO6 lovers, Please guide me in the right direction.
I currently have a 2007 Ron Fellow addition ZO6 and I have done the heads and cam, headers, exhaust and so on. But I am reallt looking to do some forced induction. Would this also be a good idea after the work ive done. With have 1 of a total of 400 made I want totake every precaution and build it right. Valaya Racing here is San Jose CA has done all of my work but they are not really doing anything with forced induction on the C6 zs.

Is there anyone that has done this and is extremely happy with the results and would recommend this? If so could you pass along the info and possably pictures.

Thanks Guys it will be greatly appreciated.

I get my R Fellows #191 back this week after the dyno I will post some picture and results

Since you are in Hawaii I'd suggest keeping your search on the west coast. Andy from A&A Corvettes in Oxnard, CA is a supporting vendor here and has an excellent reputation. I believe he has done several FI iterations on the LS7 motor so he should be able to give you guidance considering your current modifications.

MCRacing here in KC installed the first new Procharger kit for the C6 Z.
With only 4 lbs of boost the the Z was able to get into the mid 10's on it's first time to the track.

To my knowledge, Shaun (owner of the Z) has had no issues whatsoever with this setup and since he is running such low boost, no other modifications have been necessary (running much higher boost with an 11.5 CR is a bit dicey on a C6Z).

the LS7's stock pistons and valves are not exactly boost friendly if you want to boost it you're going to need to tear into the engine. I know chris from ecs threw rear mount sts twins on his C6Z and it was featured in one of the vette rags this past winter/spring. car made 563/525 or so. My 03 Z with the same rear mounts made 553/490......there just isn't a hell of alot to be gained with boost on a stock LS7 as there is on a LS1/LS6 etc.

your best bet is probably a bottle...but that might be pushing it as well without going into the motor.

The Procharger at only 4.5 lbs boost (+tune) will net out about 570 to 590rwhp very safely. Agree that higher boost than that will probably require pistons and lower CR to be safe..... but 570-590rwhp (safely) ain't too shabby!

Ktech has pistons to run 12lbs

Sorry, I don't care how good the pistons are, I wouldn't run a 11.5 CR engine at 12 pounds of boost. Not if I wanted any engine longevity....

5.5 psi ProCharger D1SC and headers making 670 rwhp. 10.8 AFR and no KR. Very Safe Tune. That is the key. Keep those LS7 pistons happy! Car is nuts. 6 months running strong!

For the kind of HP... I would change the cam and refinish the heads and intake... make close to 600rwhp N/A

Most Prochargers I see make 630 to 650 rwhp. Most NA cars I see make 525 to 570, with MOST being around 540 rwhp.

The difference in acceleration and power is not even close. I've been in cars with many different setups and the blower wins hands down.

Here's the main issue regarding the stock LS7..

The stock valve-train, even with upgraded Springs, retainers etc, remains the WEAK LINK when doing a cam swap or forced induction upgrade. The stock LS7 head has intake valve "buttons", AKA Valve lash caps, that tend to pop off and travel through the engine causing damage even on a fully stock car with a missed shift etc.

Blown motor customer Z06's are at the factory now that have this issue. GM now has "forensic" type software to determine if a LS7's ECM have been altered thus voiding the warranty, welcome to the real world...

Well maybe ECS should have put a Procharger on their LS7 becuase i know 5 people who have procharges that are making well over 600 to the wheel on a very moderate boost level and have ZERO issues. Saying their isn't alot to be gained on a stock LS7 with boost is a bunch of baloney. I saw one Procharged C6 Z06 with 5.5 psi trap at 140 mph in the 1/4 on a 70 degree day.
