See them on DSMs all the time, anyone try it on a 1.8t? Just wondering.

Tell you what, you dont want to use this on a street driven car since it becomes very loud while the wastegate is open and there is no back pressure to keep it from back firing.

and for onece, I agree with mike.

I've heard they're pretty loud. I'm putting an external wastegate on my car this weekend, and might try it out for a little while, but more than likely it will be plumbed back into the exhaust.

1" or did you go larger?

We picked up 5 10ths in the 1/4 with an open dump on a 4G63.
And thats from an internal gate.

Did you notice a difference with the dump. We picked up alot time with an open dump vs recirculated.

the farther away, the better.

You got like 3 main choices

1.just running it straight out of the wastegate(very loud)
2. Build a tube about a foot long off the wastegate will help quiet it down to a fun and loud level. Nothing like hearing the wastegate bust open when it hits the desired boost and take off like a rocketship.
3. Plumb it back into exhaust tract, you will barily hear it.

I say you do #2 and then you could just build it strategically and if you dont like it dumping in the atmosphere plumb it back in. My car is sooo loud right now I may plumb it back in, it helps to hear the engine just to make sure its not pinging. I say you start with #2.

#1 isn't an option because I don't want exhaust soot everywhere.

I'll probably just run it down to the ground to start.

I'm curious if I should put a flex joint in there if I plumb it back into the DP.
