I was going to make a little intake elbow with a bung for the PCV. I also want to clean up my charge pipes , and mount my BOV closer to the turbo. I might give it a try. It would only take a little 5" straight pipe on my setup.

I'm not entirely sold on the idea that the recirculated charge is going to help the turbo spin faster. Boost takes the path of least resistance to atmospheric pressure. It's easier to go out thru the air filter, than to spin the turbine, hey? I think the only thing that would make that charged air go thru the turbine, would be the suction of it already spinning from exhaust pressure and heat.

I'm not trying to be a jerk. Just asking . You've skills with the bender and welder.

I'm having trouble getting over the fact that dsms and wrxs come stock with recirculating BOVs, but hooked up 11-12 second cars always have them vented to atmosphere. I see it like air box resonators...not for performance, but for silence.

Awesome Setup man, I just noticed that your Charge piping is really close to your Manifold and exhaust piping, That would honestly be the only thing I see wrong in that picture, but once again, awesome setup.

wow that was a lot of hatting? for a second i thought i WAS on HT. this is HMT fokes come one now. his setups isn't ghetto and so many ppl are bashing it?

as noted above he's changing his fuel management around which is good but atleast he wasn't starting off with an fmu.

setup looks pretty good man congrats. D-series for LIFE!!

I have the bov pipe angled toward the compressor wheel and only .5" away from it, I dont think the air is going to try and revert 1 foot the oposite dirrection. Also have you ever noticed on full blown pro cars, how you never hear a bov. Most of the time this is from a full throttle shift so the throttle body never closes but alot of the time they do have the rerouted. Im not saying my ways is best because when you vent bov to atmosphere it will actually make a vacume inside of the tube causing the compressor to keep spinning but I am just saying there was a nice noticable differnce with it going to atmosphere compared to re venting.

Yes it does come kinda close (4") but when trying to keep the factory radiator to keep the customer happy you have to sometimes. Also that is what a intercooler is for anyways lol

I heard something like if it's further than 6-12" from the TB that it creates some kind backpressure and can spin the turbine wheel backwards or something. could someone tell me which one is true? and recirculating the BOV gases doesn't make you lose boost when you shift I've never heard that before. I'm not saying your lying but that's new to me.

sgoertz

when I say that about putting the bov 3 feet away from the turbo that is for recirculating.
also the idea of placing the turbo within 6-12" is a common myth, there are many of setups that have the turbo aprox 5 feet away from the TB and they work perfectly fine.

he is talking about the bov close to the throttle body i think?

sgoertz

I know he was talking about the bov close to the throttle body. I was just saying
for doing re route you want it close to the turbo and for normal (to atmosphere) that 6-12" is a common myth and it really doesnt matter where you put it.

Well last time i check. One of the best placese to mount a BOV was right off the intercooler. But i also heard the rule of it being no more than 6 inches from the TB. That's what i have always been going by.

I think if was because whent he butterfly/flapper shuts to the IM that air forced air coming in needs a quick escape so the pressure doesn't make it back to the turbo, creating backsping/ compressor surge. (correct me if wrong)
