You'll have to create the provisions. I don't know what type of BOV you have, or are going to get, but your charge air plumbing should be the same material as the weld flange for the valve. We offer mild steel, stainless steel, and aluminum weld flanges for our (the best) bypass valves.

I work for TiAL, not RPM, just to avoid any confusion.

They are normally mounted in the up pipe which is the pipe that runs up past the turbo and connects to the throttlebody.

the pressure feeds back into the turbo and out the exhaust. It does slow down the turbo and when you get back on the gas it has to spool up again. In autos while WOT you dont let off the gas. The spool-up and down is where a bov could help in the life of the turbo.

A blow off valves sole purpose in life is to vent boost to the atmosphere when the throttle blades close. IT DOES NOT AND WILL NOT CONTROL BOOST. The stock turbo spins at 130,000 to 140,000 RPM's at full boost. That is 2166 to 2333 RPM's a second. Now imagine all that pressure going into your motor you get off the gas closing the throttle blades. Where is all that pressure going to go? It "backwashes" right back where it came from, the turbo. There are MANY high mileage trucks out there that have never had a problem due to this so the choice run one or not is strictly up to you.

Never had a blow off on the stock turbo, worked dandy. With the PTE 67 however I will be fitting a BOV soon. It moves some serious air and its a beatch to keep intercooler pipes from popping off when I close the throttle abruptly. Anyone got a good used one for sale?

Re: Where are the BOVS typically located on these trucks?
well, i think even on an automatic it will help turbo life, if you let off of the throttle, the pressure between the turbo and throttle will give you the turbo flutter cause the turbo starts to spin in the wrong direction.
that causes play on the shaft (axial play) which is a problem on turbo's

stock turbo lasted 95k miles. When I removed it it had very little shaft play. If I can get 1/2 that out of my new turbo I will be happy. But a BOV wont hurt anything and the sound is better then the horse sound our stock trucks have now IMO. I plan on adding one just to scare people.

Re: Where are the BOVS typically located on these trucks?
Also, I don't know how much it would effect the exhaust pressure, because as soon as you let off the throttle, your turbo would still have some momentum which would be drawing exhaust from the engine. It kind of makes sense, that if you are forcing air out through your compressor, slowing down the wheel abruptly, that you're also creating a restriction for the exhaust. Depending on your cam timing, you're possibly creating an exhaust gas reversion situation.
Also, there is no way that excess charge air pressure would be fed back to the turbo, and out through the exhaust. There are no channels making that possible. Its either into the engine, out through the inlet, or out through other means like popping a hose, or bypass valve.

Its also nice to hustle dorks in Civics and what not and pretend you are shifting when youre really just letting off to stazy even with them so when you catch your next light you give them a launch that leaves them dumbfounded. Ofcourse I dont do this often but when I do its usually a pretty good laugh.
