Look my engine picture ("Paint drawed LOL) Crazy idea/project

[demoG40]

I was thinking a lot-
Another time, when I did the boost return mod, feel little less power, I think, the recirculation air, help to the G to run, but with the boost return mod, that air, doesn´t help the G.
If we do this?? With the T conection, maybe the "wosshhh" sound it and the G run very good.

What do you think?

I did this on my old G40. When you come off boost there is a pulse of high pressure air that goes towards the breather pipe. I put the small filter in the breather hose near where it joins the boost return. The idea was that some of the excess pressure could exit from the filter and reduce the air pressure going back in the block. I'm not sure it actually helped that much as I still got slight oil loss from the dipstick when coming off boost (even with a new one way valve and clean breather system). When on boost the small filter acts as a second inlet. It makes a weak dump valve noise when coming off boost. I cut the boost return breather hose and used a T piece section of plumbing copper pipe.

And your G sound like a blow off??

Anyone have some idea?

fit a turbo if you want a dump noise.

The noise is a very weak dump valve noise (a bit like someone sneezing) and is only noticeable when closing the throttle from maximum boost (15psi in my old car).  You certainly don't get a loud dump valve noise every gear change like a turbo car.
