Thread: does this look good for blowthrough?

the turbo I have is a used setup and has a custom outlet welded on that has a nipple for the wastegate already. Can I use the port for BOV?

edit: forget it the BOV needs to be connected to one of the TB lines doesn't it, so it pulls vacuum. I will put the pipe with the 90* bend and no ports between the maf and BOV, and maybe see if I can incorporate the 90* bend with the 2 ports to the pre turbo intake piping, and cap off the one port and use the other for breather assist. T off the FPR line from TB for the BOV and use the port on the compressor outlet for the WG

I just played around with all my piping a little more, looks like I'm gonna have to go with draw through. Not enough straight pipe to blow through properly.

Don't rush it! Buy yourself some more piping if you need to.

maf is to close to the tb imho. blow off valve should be on the hot side.

reason being, the blow off valve lets of excess compressed air once the tb is closed. its better to let of hot unmeasured air rather measured cooled off air. but thats just my opinion.

if you search for a pic of my engine bay it will show exactly what im talking about. i feel its a very efficient simple way to go about blow threw.

I'm gonna put the BOV as close to the turbo as possible, and just run draw through for now. I'm out of funding for the vehicle currently and with all thats going on it might be a while till I have some cash to play around with.

I agree with the BOV being on the hotside piping, but this is the problem I have with that method: When you run a lot, you're superheating the BOV because it's on the hotside piping. If you don't have a body like an SSQV, or you're not running a piston type BOV, you run the risk of damaging the diaphram from heat.

i run a ssqv or you saying im ok and will not destroy my diaphram. i have had any problems thus far.

my ssqv bov is about 2 feet from the neck of the hot side of the turbo.

SSQV's have heatsink fins on the body. They're designed like that for a reason. Other BOV's that don't have heatsink bodied designs (due to age, or cheapness), don't have anything to help dissipate the heat, which leads to wear down/failure of the diaphram.

Rob, I have some left over 2.5" aluminum pipping...let me know if you're interested
