adding a blow off valve?

I hear allot of volvos with them, or at least thats what it sounds like as they race threw the TS at 50mph....

I've never had any issues with my GN Buick, or any of the several other friends I have that own them. Most of us have pretty large aftermarket turbos and intercoolers along with other mods. I push 435hp with 29-31 lbs of boost and have yet to see a need for one. I don't know of any factory turbo cars that came with a BOV...Buicks didn't,not even the famed GNX, but a foreign turbo car may have. Other than all out non-street race machines they're not needed.

 

dude, 20-anything isnt necessary.

be in a hurry to take your time on the pedal, cause you cant rush these things.

roll onto the pedal, once rpm are around 1500-1600 roll off, and as your rolling off slot the next gear and repeat..

its not hard, but all about timing .

 

they dont come with BOV's because they have Wastegates instead....

um no.

Wastegates prevent overspeeding the turbo. They vent excess drive pressure around the turbine wheel.

Blow off valves prevent compressor surge due to a rapid descent in drive pressure. (I.E. Jumping off the throttle while under load rapidly.

 

you may need a few more rpms to avoid lugging after the change, but thats a good starting point.

use the minimal amount of rpm to get the job done = better mpgs.
