Installing 2 Blow Off Valve

[LT1986]

lol...if the sound is what you want...then got for the complete cop-out-kit and just install an air compressor...they do nothing...but at least your engine bay wont look like a school band recital...

Hi
Thanks for the advice. I think I'd rather not go with this idea. It's not worth putting it.

hahahaha ^. a serious reply

Indonesia ftw!

[whatthe?]

^^ kinda looks like the shear force of that ghey vinyl nearly blew the guard off

Fixed .

Yep....completely true...but your mod isnt worth doing anyway

hi mate the problem with multiple BOV is that you wont be able to get them to open all at once, especially if they are so far apart (relatively) along the intake line.

for instance one will open first and release all the pressure that will in turn affect how the rest open (if at all) and sound.

a much better solution is to try this device i think u can get it from autobahn or something:














but make sure you bring heaps of rubber johnnies and a huge stick because of all the hot sluts you will have to fight off as they chase you down the street.

A serious answer to your question, your best bet is to leave it as a single BOV. Best thing to do would be to replace it with a louder one. There are some ridiculously loud BOV's out there. I'm sure one of them will meet your demands.

Go for one of these..

I would like to ask if I would like to install 2 BOV on my Celica GT4 engine, 1 is on the throttle piping , and the other one is on the turbo piping.

Will that reduce the power of the boost ? Or will it have negative outcome to my car's performance ?

Kindly reply please. Thanks a lot.

A second BOV will not reduce boost or do any thing neg if you do it right!! A very colorful & masculine looking BOV, despite its apparent vaginal opening, can be mounted anywhere that is prominent without actually being connected to anything remotely functional.

In my opinion yes it would work and should work simultaneously as they both would be connected to a vacuum line/manifold pressure, possibly the same line with t-piece to go to both BOVs, hence venting off at the same time. As the intercooler pipes would be filled with pressure when on boost all the way through from turbo to TB, the escaping air would just flow through the easiest path and closest bov.

I would say by doing this it may take a fraction of a second longer to spool up again as all the pressure would have been lost all the way through the piping. If you did want to go 2 BOVs you be better off putting them close to each other, at equal distance from the turbo on opposing sides of the pipe. Or as previously said you could just go with one larger/louder BOV.

[PlacentaJuan]

yea i dunno if you read my post but i had 2 bov for a while on the 2jz and its impossible to configure them to vent at the same pressure.

it doesnt work.

i have tried it.

it just sounds like a normal bov and then a really quiet flutterz as the second one finally opens with not much pressure behind it.

the only way would be to use 2 brand new adjustable BOV if the same brand and measure the spring tenstion and make it equal then mount them right next to each other.

but thats a shit load of trouble to go to just to make your car sound gay

[Z2TT]

Blitz BOV's are very loud, get one of them and if you like modify the trumpet or make a larger trumpet, also mount it somewhere where it will sound the loudest.

[manny]

If you're dead keen on runnig two BOVs, try a cheap factory Nissan GTR setup which runs a pair

[LT1986]

....heres a thought....

2 bov's will actually be quiter than one

because you are venting the same amount of pressure through 2 valves designed to flow as much air in as small time as possible, you are effectively cutting the volume passing though each. cutting the audiable noise....

....this might be the reason nissan made a double for the gtr...because its quiter??
