I was just thinking, and wouldnt mounting a bov like greddys on the flat panel of the intercooler by drilling holes be a way to save money and be as functional as any other place? just a thought

 

damnit, i didnt mean to post it in this forum, it does have a little relevance though

 

already been done.Full-Race offers their I/Cs with BOV flanges.i have one on my car.


just get an aluminum flange and weld it on

They are called backdoor intercoolers, I don't see how it would save you money though, either way you need a charge pipe.

 

I dont think u guys are understanding his question...hes talking about not using a flange.. thats why hes talking about the flat surface and using a BOV that uses bolts..

I dont think most endtank walls are thick enough for adding a decent amount of threads.. at least I wouldnt trust it.. and I wouldnt like the idea of having nuts or bolts on the inside.

Yeah, bolts would be kinda hard. And there is usually somebody that would chime in and say you could just jb weld it to the intercooler..... But i wouldn't do that. But what good would a thread like this be without a reference to jb weld??

 

O I see what he meens now, sorry, but still, for ease of access and what not it is worth getting a flange welded on, won't cost much and you wont need to worry about it.

 

alright and thanks for clearing up what i meant

 

could always use rivnuts. takes care of that nut and bolt problem. Still, welding a flange is cheap enough.

 

Heres how i did my junkyard kit awhile ago, threaded the hole and used silicone as a gasket, ghetto but it worked and didnt leak.

 

^ killer.

 

As long as the end tanks have enough material it is no problem. Just drill and tap the holes and add a drop of Loctite for good luck.

 

Ideally, the BOV should be as close to the throttle body as possible.

Well in my case my upper chrage piping was aliminum where the bov flange was not. mounting the bov there ment no welding so it was done and worked fine. Full-race runs theres on the IC and havent had problems.

why is that?? it purpose is to also prevent the charge from coming back out of the turbo

sounds like bs to me, i agree with the other guy, the turbo is the important part not the intake

So what your saying is that it's easier to blow through a drinking straw rather than taking your mouth off of it?

Wrong.

The blow off valve is used to release the pressure that causes compressor surge.

But doesnt compressor surge start at the throttle body? If you think about it, the throttle plate slams shut and the intake air is trapped. The surge then starts at the blockage, which is the throttle plate.

i'm with this guy, the pressure wave starts at the throttle body and travels back towards the turbo. this is why the bov should be as close to the throttle body as possible...

but wouldn't that wave loose pressure as its traveling through the charge pipes back towards the turbo?..the less pressure in the "wave", the less that will get pass the BOV and into the turbo.. so further seems better IMO..

 

why 80% TURBOed cars have their BOV close by their TB?

thus making more sence to have the b.o.v. closer to the compressor...

probably cause most people like seeing it..and there is usually more room to mount it under the hood
