BOV on Supercharged GTO.
BOV on Supercharged GTO.
I know it cant be done on the Cobalt. But here are some pics of my GTO with a BOV. I will have a vid posted of it this weekend. You can also see the meth nozzles in the pic's

How is that ricey?? A BOV can sound great on a supercharged car, because the S/C has to spin down with the engine, it can't just stop from compressor surge like a turbo can. Heard one on a procharger 5.0 mustang that sounded great.
It's cool guys. I talk to him all the time he lives close to me. He is actually a really nice guy lol.
On a serious note. The car builds boost a lot quicker now with the BOV. I actually hit 1.5psi just revving it in place.

Casey is dyno proven to give you 2 more PSI

u NEED THAT bov..we have internal bov and centrifical supercharges and turbos have external bov. the difference is u can actually damage the turbo(exhaust) or the centrifical superghatger with the excess intake charge. just releases extra boost or intake charge. U cant here ours cuz its internal. meaning it releases the extra intake charge back threw our intake and doesnt damage the root charger.Its not rice u.... need the **** use it.

Ok, minor comments. it IS possible to put a BOV on a roots style supercharger (what you ss/sc guys have....ive done it for a customer. Personaly, not my cup of tea). But on a centrifugal supercharger such as a procharger, its great, and has so many advantages over a BOV on a turboed car.
The fact that a turbocharged vehicle doesnt provide boost until 3500ish rpm (exhaust driven), and when that throttle body closes, the presure goes up and out. which is BAD for the car simply because the MAF sensor already measured the air, and its not nearly as beneficial as a recirculating bypass valve.
vs
The fact that a procharged vehicle is belt driven, it creates boost instantly and has little to no vacuum. When the throttle body closes, and theres nowhere for the pressure to go, it loses velocity dramaticly, and can in some cases create backpressure on the procharged settup. granted it will bog for a split second when you hit the gas its minor, but the change is measurable. The BOV allows for the air to go up and out, sound cool the whole nine yards. Granted the MAF has already measured the air, it doesnt really matter. Instant boost eleminates that variable.
So is it rice? No.
Do I think some of you people are rice for saying its rice? **** yes.

Along with the BOV and Meth the car is a different animal now. The car revs so much quicker and Redline (6900 rpm) comes up fast lol. Waiting on my smaller pulley which is a 3.5 from a 3.8 now. Then a retune and hopefully the magic 600 rwhp comes up. I am @ 7.02psi @ redline right now so going with more boost is not a problem on a 10.9.1 motor as long as the tune is right and you use plenty of Meth to help it out. Over on ls2gto.com There is a guy with a d-1sc ( MINE IS A P-1SC-1 SMALLER) is running 14psi @ redline but has 4 #15 jets in his Meth kit and bolt ons and is putting down 700+rwhp on a stock LS2.
some people do say that an atmospheric bov is rice. they just say recycle it, run a bypass back to the intake side of the charger. but good placement on it. tial bov, nice. ive got a hks ssqv for my saturn project
Yeah my friend who owns joeblowracing.com sells them with his kits. He told me he would give me one if I put it on the GTO so I said what the hell BTW it sounds just like a turboed car when you let off lol. You just got to spend some time on finding the right spring pressure for a SC setup. Here is a pic of what was on it.

hmm thats cool I was literally just wondering yesterday if I could use a BOV when I get my procharger considering it uses the same basic principles as a turbo, I have a 2.4 ion... time to call kevin about this
