compression and supercharging
I need a little advise on deciding to supercharge. The C6 has a compression ratio of around 11:1. Procharger states that this is not a problem, however everything I read states a maximum of 9:1 for supercharging. I understand that under normal driving the supercharging won't put that much boost into the engine, but under hard acceleration, the boost will be 1/2 atmosphere 6lbs.
My fear is blowing a head gasket or blow by the rings. Am I correct in my fear of supercharging my C6. My C6 only has 5100 miles. Also, will supercharging blow the warranty? Thanks for the help.
By the way, I just contacted ATI Procharger and priced their kit for the C6. The kit for manual trans is 7k and comes with new injectors, intercooler, procharger, and a tuning certificate where you can send in your computer and get it programmed.

Supercharging will reduce the engine's life. The more boost you run, the less life it'll see before you blow something and have to tear it down.
At 6 lbs. of boost, you should be okay. But I wouldn't go over that and expect any reliability on the stock compression.

you start playing with blowers and you need a budget for upgrades that naturally follow.... tranny, clutch, rear end etc. Course this applies to any major engine upgrades..
The $$ for blowers can be redirected to cam and heads and headers and get great improvement as well. 6 psi is about all the engine will handle with the compression so the the 100 hp gain you are limited to can be easily exceeded for probably less $$ IMO.
I love the sound of a blower and the raw power but you have to weigh the cost/benefit and how much time and effort you are willing to put into it. Have you priced a blower package installed? Probably > $6k. Thats a lot of "other mods"

supercharging
I had a vette supercharged by GREG CARROLL of CARROLL SUPERCHARGING.He told me he adjusted the comp.ratio to accomodate(sp?)the chargers needs.I'm sure with a knowledgable tuner,you won't have any issues.I don't have a c6,but i'm bordering on getting one now.I love them!I have had some experience,good and bad,with supercharging.Done right,it's a blast!No real side effects either,if you're running normally and not into it every ten seconds!good luck.oh,and get intercooled!

That is correct it is definitely more than 100hp, more like 200. What I am going to do is run a 5psi pulley with headers and a small blower cam (reduces back pressure) and run the torco race fuel additive, you can buy a 5 gallon bucket that will last you a year for $180, it brings your octane up to about 99 if you use 93 gas. That will reduce any detonation issues.

Does Procharger give you a 3/36 warranty on the motor with the $7,000 purchase + $$$? installation?

But really that doesn't have much effect on how much hp. the bottom end can handle, it more depends simply on how well the bottom end is built. I have seen stock c5's pushing over 600 on a stock block, I personally would not go beyond that. The key is to keep your boost down (5psi) Get a GOOD conservative tune, and headers. I believe that the engine will hold up as long as you are smart, don't push it in the heat, don't dog it, over rev it. Run a high octane and you'll be fine.
A stock block @ 600HP has a short, expensive life.
