Hey i was wondering if anyone else on here has run a bypass valve on there cars with aftermarket intercooler piping, i do not want my car to back fire after every shift it gets annoying haha

Yep just use a forge copy like I did.

They are heaps easy to fit all you need is 2x1" weld on hosetails some 1" hose and a couple of clamps.
And someone who can alloy weld for you.

I do on all my cars, either greddy style bov will work, just recirculate it back into the turbo inlet.

alright i lied i have one more question for stock turbo for now would it work good with 2.25 inch piping or 2.5 the intercooler i have is 2.5 i think i got a kit n i was thinking about buying the bov with it cxracing.com: 2.25" Universal Aluminum Piping Kit, Mandrel Bent, Polished, 2.0mm Thickness Tube, 18" Length

Funny I'm actualy in the same boat..

Either 2.0, 2.25, or 2.5

This tiny turbo has to fill up alot of room..so anything over 2.25 will be a strain on the turbo..and shorten the life span.

I'm prolly going with 2.25..and that's with out a turbo killing fmic.

Bov too, just for spite. And cause I miss my old one.

**randys626turbo** · 6-21-11, 19:14

i think a 2.25 inch setup will work best for me because the intercooler i have is pretty big, but i will upgrade and put a bigger turbo on after i get suspention and wheels n tires

**randys626turbo** · 6-21-11, 19:15

and im definatly putting a hose at the end of the bov to recirculate the air, i dont like backfires

**Leev** · 6-21-11, 20:56

Yeah a lot of people seem to not like that side affect.

I only got a small pop 40% of the time...and a quiet pop at that.

I think it also depends on a lot of other small things that some don't recognize.

**randys626turbo** · 6-21-11, 21:12

well considering my exhaust too i hate it, i want it to sound as stock as i can basically is what im going for...people look at you really funny as you fly past there v8 mustangs haha

Sleeper is always fun.

Wait..mazda what? Mx what? Rx 7 huh..

Man, people have no idea what these cars are, what they can do...

I actualy had one person say, they had turbos back then?

I didn't know what to say...

Nvm the water injected forced induction WWII airplanes....

haha i had some kid ride with me that i work with he was like so intertained it was funny he was like ive never been in such a fun car, and the only way you will be able to tell its turbo charged is if u look at the front which is what im going for

**Zach** · 6-29-11, 1:43

Funny...with or without venting to atmosphere I after-fired the same frequency.

**randys626turbo** · 6-30-11, 22:00

my car will rich pop as it is i just dont want to make it worse really...

**Leev** · 6-30-11, 22:06

look what I just installed.

im not calling anyone a liar, not try to start anything, i just want to say this, cause i think its funny..

i had more back fires with the factory bpv, than im having with this bov.

know how many ive had? 0 , none. just funny to me. and thats with GT injectors on n/a ecu... vaf screw is leaned a good amount though.
