where should i weld my bov

[franciscoescn]

I just got a new bov from SYNAPSE its the synchronic bov. My question is where should i weld it on the cold pipe or the hot pipe because i heard that its better on the cold pipe. I have my old cheapass greddy rs bov on the hot pipe.

coldpipe
minimum of 20 inches from the throttle body

Whats better about the cold pipe beside it been cooler

 

[neox.286]

honestly, I wouldn't know the answer to how they would differ in sound

Personally I would think you would want it on the hot pipe becuase idealy you wouldn't want to loose the air thats already cooled by the IC.

P.S. I don't know to be honest as I dont know much about the entire turbo gig. It just makes more sence to me logicaly.

 

[neox.286]

to tell you the truth I honestly dont think it would really matter which pipe you ran it off of....neither really have advantages or disadvantages

as long as the valve does its job is all that really matters haha

 

[SeR_Cyclops]

they put it on the cold side so when your under boost and you let off the gas it vents the pressure that would have been forced back through the turbo known as compresser surge.

 

[neox.286]

yea, but it would do the same thing on the hot pipe too

If recirculated, the cold-pipe is the best choice due to its close proximity to the intake piping.

 

[neox.286]

good point!

 

[turbolife]

Also, the cold pipe is better for performance as well.

The shorter the vac line going to the BOV/BPV, the faster the response (it should also be a dedicated vac line). Generally, on our car, somewhere on the cold-pipe will be closer to a suitable vac source than the hot-pipe.

ok guys i ended up welding it on the hot pipe because thats where i had my old one and turnd the car on and it stalled. Do I have to adjust it or what because i also got a check engine light on.

Personaly I would put it on the "hot" pipe as close to the turbo as possible because the main reason we use a BOV is to save the turbo. BOV saves turbo, Wastgate save motor. But this is just my two cents.

best over all setup is the dual set up you want a 50/50 set up faster spool plus gas get released im going to do the dual set up next

Please explain how recirc will get faster spool?

 

[neox.286]

no, it doesnt...

all that 50/50 does it help reduce the turkey noise from compressor surge

 

[bstdtimsp]

Please explain how recirc will get faster spool?

gases from the recirc valve get forced back into the intake adding more volume to the air in the intake during shift so there is more pressure in the intake chamber

double post

 

[neox.286]

yes recirc is better, which doesnt matter which pipe you are on, but you werent saying recirc....you were saying dual bov setup, which will not affect spooling at all

recirc also wont change your spooling that much at all to tell you the truth, people can argue that point, but the truth is it doesnt make any of a difference because when you blow off by the time that turbo even begins to start spooling again that air has already gone through that turbo and is on its way to the throttle body...

it would if the filter pipe was a pressure pipe, but its not

what about for stalling purposes/moving the maf? then should bov be placed on cold pipe with maf behind it(in between bov and throttle body?)
