Supra Turbo BOV

[noremacsupra]

Hello,
Is this normal?when i rev on the my engine the air from the 3000 pipe goes to through BOV then back to the turbo accordain hose?The red arrow is the pattern where the air goes after i rev on the engine.

yeah, thats normal. its supposed to be this way. (im pretty sure but if im not someone correct me)

That's exactly how it's suppost to work . And when you switch to an actual Blow Off Valve (the stock is a bypass valve of sorts) it vents the air directly into the atmospher, causing the engine to load up on fuel because it thinks it's getting that extra bypassed air put back into the engine, this causes it to backfire and even stall on some 7M's .

Isn't that why many people keep the stock BOV in addition to the aftermarket BOV?

No, Thats because they are lazy.

 

[starscream5000]

^ true, but it still does it to a certain degree that way.

you forgot cheap too! the stock bov is only good till around 10 psi or less and with worn out parts and however many miles its probibly blown already

 

[mattgo]

how could you be using 2 Blow off vavles at the same time? pics?

does this than have an adverse affect on gas mileage?

Yes.

I run 2

I run 2

Running 2 BOV's seems a little pointless....... I think..... the stocker if it is weak will open before you hit your desired boost level (as mine does:icon_evil ) then by the time the other one kicks open, there is nothing more to vent, as the stocker already bled it off.. am i wrong??? BTW where is a good place to get a cheap BOV

 

[Brady]

Yes.

its cause it fools the AFM into makin u run rich or something right?

isnt there something you can do the BOV itself to prevent that?

cause i like good mpg almost as much as the quickness

Bosch BOV is probably the best route to go to keep the stock configuration: http://www.supramania.com/forums/showthread.php?t=236

When running high boost one BOV might not have the capacity to vent the air and will cause compressor surge. That is why IJ has two.

TiAL BOV and stock BOV

Does that Tial function properly with no vacuum source? Seems like it would leak boost.

 

[whudafux]

Actually it doesn't leak. It sounds great on the car. I've capped it off better since then. That was just a picture from the first test drive. Now it holds 8 psi all the way til redline. It held 10 psi the first test drive until my 3000 to TB coupler exploded. Then I put it back to stock boost.
