Yeah, my 4.1 is pretty damn short (probably the same). it dumps straight into the compressor inlet plenum. This makes that Bosch valve pretty dadgum loud though.

But I like the way you did yours, and the diamond plate heat shield is oddly attractive. Congrats on getting it running.

Yeah my BOV (recirc) is loud like this too, much louder than the turbo itself. I am going to try swapping around the inlet/outlet like i had it before (with BOV, no recirc). It works either way and it is quieter in the other direction.

I want dynos too! Dyno test results are coming as soon as I can get some dyno/tuner time scheduled with BEGI.

Sounds like a plan! I wish I was that close to BEGI... :(

Yeah it is cool. They are nice folks to hang out with, and there is usually something interesting (or several things interesting) in the shop to check out.

It broadens the efficiency islands a bit at the low end, and helps prevent surging.

Scroll about 1/2 way down.

If you are into the turboz sound, it makes a hella kewl whistle when it spoolz.
