turbo/forced induction guys... quick question for intercooler setup and BOV placement

[Yaj Yak]

which way is better from my awesomely done paint drawing...

the distance to the throttlebody the longest, or the shorter?

also, where is the best place for bov, closest to the TB or farther or where?

I would say short from the intercooler to TB......Less time for the air to cool down before it goes into the the TB

And the BOV closest as possiable to TB to get rid of the air before it hits the blades of the TB.....

wouldnt you want the air to cool...?

 

[Riski]

The air would cool through the IC.....thus coming from the Turbo to the IC would be longer thus be a cooler charge then coming out the IC to the TB would be a shorter run of pipe thus being a cooler air charge going inside your motor and have less time under the hood....

Turbo---------------------------IC-------TB
This would be longer piping thus being a cooler air charge

vs

Turbo------IC------------------------TB

thats what i thought you meant... sooo im gonna edit what you said... hhaha to how i understand what you are saying...

I would say short from the intercooler to TB......Less time for the air to "warm back up" before it goes into the the TB

Hard to explain, easier to draw it out....

Wow. Joe really can be productive in a thread? Whodathunkit?

On top of that, I agree. Shortest run should be the cold side of the IC to the TB for the exact reason Joe stated. Less distance for that cooler intake charge to travel, thus less time under the hood to heat up.

 

[Yaj Yak]

i just read this as far as bov placement goes.... but bov placement doesnt seem as crucial to me as pipe routing.

The vast majority of people will tell you that you are supposed to place your blow off valve within a couple feet of your throttle body. I am here to tell you that this is not the best location for your blow off valve.

The best location for your blow off valve is going to be in between your turbo and intercooler, on the hot side.

Think about it. If you put the blow off valve on the cold side (after the intercooler), you are pushing hot air through your intercooler for nothing. This increases the speed at which your intercooler and motor become heat soaked.

By putting the blow off valve before, or even on the intercooler itself - you allow all of the hot compressed air to escape to atmosphere prior to passing through the intercooler. A blow off valve does the same thing no matter where you place it on the charge piping. Knowing this - it's only logical to put it in a place where it relieves hot air rather than cold air.

But the flip side to having it on after the IC would be when the bllades open up to the TB will be straight cold air and the BOV after the turbo is fine as well but I would thing it would take a millisecond long to pass through the IC than straight tubing, and you are dumping COLD air on your motor......

I have to atleast do one thing nice on this forum once a month, and the month is almost over

im gonna you right in the head.

i was going to say that i dont have a choice with mine, but luckily the BOV will be on the hotside, i dont really have a choice unless I wanted to put it like where my batter is at the mouth of my TB on the passenger side

 

[Yaj Yak]

why the sneaky eyes. are you relocating your battery to the trunk for the passenger side piping dealio or what?

fbody intake, he wants a race-car setup, i choose to kevy's response

:smile:

 

[Handsome Jesus]

I think we are going to have to relocate the battery. prolly put the BOV where the battery used to be. then figure out some other cool toy to fill up the rest of the space from where the battery was...

[Turbocharged400sbc]

need to put a fuel injector and spark plug at his BOV to add to the flame effect

My bov is on my I/C. I would think between the Turbo and ic so youre dumping hot air out of the pipe before heating up the ic for no reason.

Venting to atmosphere is ok with a turbo gp and a maf?

wtf? doesnt this go completely against the info kj just posted?

yep. think bout it homie. maf is after everything. blow thru setup.

 

[Bob Kazamakis]

Edit: I get it now. The below comment makes sense for mine only cause my maf is pre turbo.





Yea but you're letting metered air out before it reaches the O2 sensor. It's probably such a small difference....

 

[Bob Kazamakis]

I want a blow-through setup now.
