Can You Put Blow Off Valve On The Turbo Side

[MAD R33]

hey guys is it ok to have the blow off valve on the Fmic pipe on the turbo side

as i have greddy plenum on my motor... and i dont want to run a long pipe to plump it back to the intake pipe

will having the bov on the turbo side make your turbo have short life time ect ect ?

any info will be good thanks

that is perfectly fine there will be no problem with you doing that.

The throttle response going on and off boost may be negatively affected.

hey mate what you mean by that thanks

nissan put the stock bov where it is for a reason. when the bov opens the air keeps travelling in the direction it was before the throttle closed. moving the bov closer to the turbo means that all the air between the bov and the turbo will be moving in the opposite direction to the normal direction of flow. you will also end up with a loss of pressure between the bov and the throttle, so the nearest amount of airflow will be further away from the throttle. when the bov is near the throttle, the pressure will be reduced but the air will still be flowing in the right direction so you will have better response when the throttle opens again.

doesn't affect toyota's or any of the other cars that run them on the hotside intercooler pipes

don't get me wrong, it doesn't suddenly make the car a slug to drive on gear changes, etc. nissan had it down near the cooler on the s13, etc.

The thing with BOV's (f**k a I hate that word...such a shit word...BOV...)

is that even the 50mm race ones arent going to expel 40+lbs/min of air in 1/2 a sec

will reduce the pressure, but not completely

just dont run a bov. ive deleted them from my last 2 turbo cars.. (wrx & r33 gtst)

not good for the turbo if you have no BOV

[mad082]

the general public think not running a bov is worse for the turbo than it actually is. sure it isn't the best for the turbo, but it isn't going to kill it in a few weeks like some people think.
