Tubing nipples that is...

I'm routing the lines for the external wastegate and boost controller (Blitz SBC-iD 3).

I have two nipples that I had welded onto the tubing that comes from the turbo to the IC.

Blitz directions show to use a pressure line from the turbo housing and one from the IC tubing before the throttle body.

The line from the turbo housing goes to the side port of the Tial wastegate. The line from the IC tubing before the throttle body goes to the Blitz controller which then goes to the top port of the Tial.

I'm wondering if I can use the two nipple that are on the IC tubing right after the exit of the turbo for the two pressure lines to plumb up the Tial? They would be seeing the same pressure so I don't know if that would be an issue and that's the reason why Blitz shows different locations for the pressure sources.

 

that's fine the way you plan it. blitz's instructions just allow for slightly quicker wg reaction, but your way is still ok. also you might be boosting slight less than what the pressure the intake ports are seeing since your boost reference is pre-ic. there's a pressure drop across the ic which your boost controller won't be able to recognize.

 

Here's a diagram of what I was thinking:

 

Well I don't really want any delay in wastegate functionality.

Also, there are some that are using post IC AND post throttle body source for the pressure to the in port. Is that an issue?

 

boost reference from the intake manifold is fine.

 

Hey atilla are those the OMP lines running to the intake?? Im a little confused there.

 

Yes a nipple on the intake tubing. Those lines are supposed to see vacuum all the time. Same as with the stock setup. Some people leave the lines off completely.
