Just a question if you have a 4l60e and put a manual valve body on it? Do you need a blow off valve? I dont really know much about turbos and thought that automatics didnt need them but was wondering if u need them with a masnual valve body.

to my knowledge all turbo set ups have a BOV, but correct me if I am wrong

auto cars use the wastegate to release pressure, manual cars use a blow off valve.

i dont see why you couldnt run a blow off valve on an auto its just you dont need to.

You need a wastegate for the "hot" side to maintain and control boost and predictability and a BOV for the charge side to save your wheel, couplers, throttle blades... ect...

Regardless of trans, of course.

It's one of those personal opinion type things. I don't run them on either of my auto cars. Some people are dead set against them, some people say you only need them for small shaft turbo's, some people say you must run them on anything that's turbo'd.

If you ever slam the throttle blade shut, you should have one. I'd use one on an A4 as insurance. The pressure will backflow through your turbo and will cause damage over time.

I use one on my auto. If I am in full boost and loose traction & let off the throttle mometarily how is that different than a 6 speed? (this happens often) I think it would be hard on components without the BOV

They make blowoff valve's for a reason. Use one. It is the correct thing to do!

why do they ask when you purchase a turbo kit if its manual or auto and then send you auto kit without a BOV ????
just looking for a good answer

They just forgot to send you one. I don't know of anyone that has a forced induction setup of any kind that dosn't use one. It come's in Procharger's kit standard,but I guess they don't know anything either!The wastegate is also necessary for turbo's,because that is what regulate's the boost.
