i am VERY interested in getting a procharger for my 82 firebird with a carburated 350 swap in it and a currently have 10:1 compression and need to know it it is too high and if it is then what are some ways i can lower the comression thanx

 

most of the carb kits run around 6 PSI, have you considered a roots kit (way cheaper)? what cam do you have? you may be able to run the 10:1

 

You can run a procharger/ carbed system @ 10:1 cr, but the amount of boost you can use will be directly related to the octane of the fuel u use.
You can add water injection and run some more boost.
It acts like a octane booster, suppressing detonation
by slowing the burn rate and controling combustion temps.

You can run more boost for a said octane of fuel by lowering the compression ratio.
7.5 to 8.5:1 works well with street gas and no intercooler.

You can lower the compression ratio of your motor by swapping
heads with larger combistion chambers or swapping pistons
with a dish design.

If you now have low performance 64cc heads you can kill two birs wit5h one stone by switching to a large chamber
aftermarket high performance head.
Allowing more boost and free'er breathering = lots of HP.

 

procharger also tells you on their web page:

http://www.procharger.com/bebs.shtml

Or, to make it easier:

For pump gas (91-93 octane) applications, a compression ratio of 8.5:1 to 9:1 is recommended for boost levels of 8-10 psi. Higher octane fuel will allow you to run higher boost levels, approximately 1 psi for every 2 points of octane.

But, you should check out that page anyway, cause it has a lot of useful info on it.
