Thread: maf and blow off valve location

Loc -

Where in the 505 are you?

Albuquerque, I mean the brass or copper pipe that comes out the gtir intake manifold. It is where the stock recirculating bov is plumbed. Here is the diagram. http://sr20-forum.com/showthread.php?t=1126

oh, idk, i have a stock DE motor.

I have had issues with my big turbo and maf fluctuations on my setup. I have a 4" intake pipe and when the engine blows off, the maf readings go all over the place which tells me that there seems to be laminar air flow issues, or the air in the intake pipe is stalling. This was causing the car to die if I pulled and let off the gas with the clutch in. Revs would fall and the engine would die. The problem has been mostly solved by using the z32 maf instead of the lightning maf.

But it is still there. So I am going blow through. The car doesn't die anymore, but when I shift quickly the car has a slight hesitation before rocketing off again.

did you have the blow off valve before or after the maf?
