GTM Stage 1 Super Charger Install--Kentmo

Yeah, the flutter and just the blowing sound is ridiculous! There has to be a way to quiet it down. I've seen plenty of supercharged cars that don't sound the way ours do. Of course they're not GTM made kits, but there has to be some kind of work around for it.

I ordered the WHITE spring, just put it in yesterday. Will let you know as I drive it more. I'm wondering why we can't use a regular
Bov rather than a blowback?

Drove about 20 miles on the new spring. Helps a little but really not the solution.
Other than you and me, I have not heard anyone else with this issue. I expect the blow off whoosh, that does not bother me.
I read another companies description of their plumb back valve( can't remember their name) but they wrote that Nissan's tend to have the issue that we're experiencing....
