What's going on here is I have a CRX with Full-Race Top Mount turbo manifold. I'm running the Borg Warner T-67 Turbo and the outlaw intercool big o thing. I'm using a one piece front end and in order for the intercooler to clear the hood I had to relocate the wastegates down and one to the side. Now my concern is this is taking away from the design and not sure if this is going to cause any boost control issues. What do you guys think?

 

i'm no fluid dynamics engineer, but i don't think 6" of pipe will cause trouble

 

Ive extended wg tubes longer than that with no issues.

 

I like what I hear anyone else have input?

 

Had to do the same thing on my street car unfortunately I don't have any results yet. I have that same intercooler stuffed into a 4th gen prelude, and the same manifold....

If I had to speculate, I would say any issue would be marginal/un-noticeable. You still have the volume/flow of two wastegates, so I don't think you'll see any control issues.

 

on a side note... wow.

I want to see this running.

 

Yea you and me both.

 

you might have some heat issues with the gate top because it's so close to the runners

I’m actually going to be relocation them again for this exact reason but before I do them again I wanted to make sure there were no issues with relocation. So other than heat you see no issues?

 

if it controlled the boost you want before, nope no other issues

 

TIAL I have not ran the car yet this is the first install and have no clue on how it will act. Some people say it will be hard to control boost and even more so at low boost.

 

You still have good waste gate priority off of the collector and your piping is short, smooth and the same diameter so you should have 0 issues, but as TiAL stated, that left waste gate will have diaphragm issues that close to the runner...

Given the close quarters of your setup, even though the manifold is ceramic costed, I would run water lines to both waste gates as added insurance and to try and keep the diaphragms as cool as possible

 

Thanks wantboost.

I woulld ike to get the opinion from Full-Race and The Shodan where you guys at.

 

Good luck getting full race in here... they're really busy.

I talk to theshodan enough that I know he would say basically the same thing lol

 

I tend to agree with this. You're ok, but I'd still run water to the gates to keep the housings within good temperatures.

 

I win :p

 

Thanks guys I feel better know. And wantboost yea you win brother.
