I started talking to my mechanic about installing a greddy tt system, but i want to add a blow off valve. He was curious if it could be welded directly into the intake piping from the intercooler right before the throttlebody, or if it would have to be cut and add have the bov welded to a seperate pipe and have it inserted. I am ignorant about this so any helo would be greatly appreciated

 

I'm not too sure but I think putting it anywhere near the MAF is a bad idea...

 

that is a good question but i believe that you can add it after the intercooler on the pipe from the intercooler to the TB

 

The blowoff valve should be inserted into the system before the MAF sensor. If you place the BOV after the MAV in the intake tract, the air that has been metered by the MAF will be released into the atmosphere without the knowledge of the ECM. This means that the ECM will still inject the amount of fuel needed for the combustion of expelled air, causing an overly rich condition. So if you want to introduce a BOV, put it in before the MAF so that the ECM will know exactly how much fuel to inject.

 

If you could put it before the intercooler, that would be ideal. That way you are venting heated air and not intercooled air. Since the Greddy has two pipes going in and one going out, the only way to do something like that would be weld in an H-Pipe.

So, I'd say your best bet is just to add it right after the intercooler. What R34racer said is very important. It doesn't really matter where you put it as long as it's before the MAF.

 

I went out and looked at my car because I want a replacement surge valve.

After the MAF and pre TB (minus the two hose clamps) there is only 3-4 inches of rubber hose before the MAF.

I don't even see this as as option and should not even be considered, besides it would never fit (just glancing at my Intake.)

Pre MAF blow off valve?

Where?

 

do they make BOV's with 3 inch I.D. venturis?.......i didn't think it was possible to put a BOV after the MAF .......but thats just me

 

.

 

well in theory it may work I guess someon research this, I want one.

BTW, WTF is all this crap here?

 

I am talking post MAF pre TB where the 2 hose clamps are, I just don't understand why that is even being considered? Why not just put one where out tin foil 2 dollar stock one from ATI is?
That is my plan. K.I.S.S. Don't introduce more alterations.

 

pay no attention to that, its just for looks

 

LOL,

And noise right? a 4800 rpm Concord Jet?

Peas be unto you my hard working good and faithful servant of ATI, Don't make me Fanta Shataka this thread

 

i like it cause its shiny

 

It's possible, but not very good for your car and will make it run like azz when you release the throttle. That's why we were saying it doesn't really matter where it goes as long as it's before the MAF.
