Custom Cold Side for Tial is built

[Edkiefer]

IDK, I am a fan of routing it back to turbo, IMO that is wasted boost going into the atmosphere ,at least on street car .
I also rather have it quiet ,but that is just me .

Actually their are two schools of thought on this, the hotside argument seems to be the winner for cars running centrifugal type blowers, however on a turbo car when the throttle plate closes the most pressure is immediately right there, so the coldside is favored. In the grand scheme of things I think it is probably negligible. One things for certain, it will be much easier to fit a Tial 50mm on the coldside of the Ecoboost.....

Weather its turbo or supercharged makes no difference as both vehicles have positive manifold pressure, and a TB, and I am involved with both applications.

Vehicles equipped with intercoolers always have higher pressure on the "hot side".
On the Ecoboost if you check the before and after IC pressures, you will be quite surprised at the difference.
The closer you mount a BPV or BOV to the turbo, the quicker the response will be and optimal control of surge. Due to this, smaller valves can also be run.
This is why most every OEM valve is on the "hot side" ;-)
The EFR turbo is a beautiful example of this. They are able to run the smallest of valves at very high pressures while maintaining very good control of surge.

The "wasted boost" does not go back into the turbo, it vents into the intake pipe, this is done on production cars to keep them quiet, I don't care about that, I'd much rather hear the sweet sweet sound of a Tail 50mm, which is the last BOV I'll ever need since they can handle well in excess of what I plan to make. Some will make an argument that the extra air dumped into the intake keeps the turbo spooling, but let's get real, it's already spinning in excess of 100,000 rpms.....

Touching on the other point, these cars are MAP not MAF so venting to atmosphere is fine. MAF systems require recirc due to the metering setup.

Correct. I mean, no way Marty you wrong dude... way wrong... hahah.

OP - The DIY is strong in you, and I like it. Good work. If it works it works!

If done right, it aids in turbo spin up , its going straight into turbo intake .
You want to keep it spinning , I can tell ya it does make a difference .

If you like sound great both ways can be very effective , I just gave IMO .
I have done it both ways, on many vehicles .

All my DSM's had the BOV right by the throttle body [emoji3]

In addition to some of the other comments, having the BOV as close to the compressor outlet(hot side) keeps the turbo spinning against less resistance during shifts it also allows the charge air to stall in the intercooler during shifts allowing extra cooling to occur.

Either way good DIY to the original poster

all this talk about response between shifts

A6 FTW!

you like rowing that MT-82 all the way back to China where it was slapped together?

:lol:I keed I keed

sorta....

Decided to polish the most visable part at the throttle body, the rest will be thermo tec wrapped.

im new to all of this stuff :shrug:

 

[mmorningstar]

Starting hotside....

And yep.....workbench is a mess....lol

 

[mmorningstar]

Hotside complete, needs polished

When will u have these installed?? If only I could weld
