- I'm not here to discuss rice factor, you wanna do that start your own thread.
Testing out his venting mod. Needs several zip ties hehe. So far, the car is running rich under immediate decel (as expected). Also when cruising and letting off the throttle with clutch disengauged the RPMs tend to linger down slowly sometimes, Definitley an effect of f*cking with the vacuum.
One fear is of my valves vibrating into new positions.
Also my other major concern (also the same concern with my Brady valve mod) is the efficiency of this. I fear the valve may not be opening fully or quickly enough, potentially causing compressor surge (turbo backspin, just ask sick6 what this can do).
I think this version may be better than mine in the fact that you don't have to worry about a Brady valve getting shot off. But not as good as it tampers with sensitive vacuum that could potentially cause bad MPG or Turbo destruction.
I'm carefully listening for compressor surge after every blow off.
I'll give it a few more weeks of testing, etc.
But, as with my version of this ghetto mod, it will probably end up scrapped back to stock setup, and if you're truly in love with the "whoosh" and desire less side effects and worries, I suggest buying an aftermarket valve.
