[QUOTE="IUP99snake, post: 480769, member: 7060"] you can do that... you just have to have a blow-thru MAF setup to vent the bypass valve to the atmosphere. see, the reason your blowoff valve vents to the intake pipe is because all the air has gone through the MAF, and has already been metered, therefore for the car to run right, the air must remain in the "system" prochargers come with a blow-thru MAF setup. They also come with a lil "flapper valve" BOV that vents to the intake pipe. But, i have mine vent to the atmosphere, and it's "hide your children" loud. you can run a blow-thru setup on your car, too. Just get it programmed into the chip. and make sure that your blowoff valve is BEFORE the MAF, so its venting unmetered air. The reason why most turbo guys have their bypass valves venting to the atmosphere, is because most import EFI systems are a "speed-density" system that has no MAF. Honestly, there is no performance advantage, or functionality of venting the bypass valve to the atmosphere vs. the intake pipe. -Homer [/QUOTE]
