can u put a BOV on the supercharger on the colbalt? a friend of mine said u can...maybe sumone would know more than him or I? thanks for the help

 

Alot of the high compression supercharged cars have blow off valves to prevent an intake explosion...not sure about the cobalt.

 

is there anyway I can find out? mabye contact my dealer or summin?

 

Or try contacting a vendor that is going to make aftermarket parts for the Cobalt.

 

My personal favorite.. I put this one on my buddy's 240sx with the SR20 swap...

Mmmmmmmmmm... Loud.

 

yea,like I said it maybe a dumb question...I relooked thru sum older threads and the specs were out...from wut I read on the posts and thru reasarching roots type superchargers can't not have a aftermarket BOV it already has a internal BOV that is currently in use....oh well...that's cool tho

 

Well by internal BOV they mean a wastegate. I don't believe supercharged cars have an area for mounting a BOV per se. All forced induction has a wastegate in some kind (and turbos can mount BOV's over the wastegate basically to release pressure faster, and make a cool sound) It doesnt improve performance but it does help either the s/c or t/c cool down faster, the release of pressure (usually at a shift point) helps alleviate the s/c or turbo so its not CONSTANTLY heated (constantly blowing that is). It just forces excess air outwards to release pressure, the basic jist. Plus it makes a cool sound! I want to get a BOV if I decide on getting PSI-FI's twincharging kit.

 

I know RSMRACING has BOVs for superchargers but i dont think they are using a roots type supercharger.

I looked on their site a while back (rsmracing.com) and saw tonnes of BOV

but again, not sure about the M62

 

ummmmmmmmm.... A wastegate is an exhaust bypass in a turbo system to limit the pressure produced. Since a S/C is belt driven, there is no way of doing this (for the most part). A BOV is used to prevent a spike in pressure when the throttle is snapped shut. If one is not used, AND the pressure device (turbo OR S/C) is BEFORE the throttle blades, snapping the throttle closed will cause a pressure surge that can damage the pressure device. A BOV is used to release that pressure spike...

 

blown cars have a blow off valve, but it vents back into the intake.. something about drivabilty or something..

 

Thats called a diverter valve and is used instead of a BOV

 

Very good! It is used on engines with MAF sensors, so that the computer doesn't think the air went in, when it actually didn't...
