hey does it bring a flang and what conditions is it on, i will give you more than 100 if it comes with a flange

Sirex

i have the box, instructions... but guess what.. i Learned how to use the ****** and got no fluttering.. i removed a spring.. set it to soft then tight with my hand then the bolt... car pulls like a ----- now... very good.. and i have that ricey sound from the eclipse on fast and furious.. the valve cost me 190 shipped with the flanges and stuff.. sorry for the post.. i was just pissed that im a goon and didnt spend 30 minutes to learn how to work the ******...

The technical term on "flutter" would be compressor surge, I hate that noise more than anything!

Damm right. it was really bad... finnally set it up right.. runs great sounds great.. no surges...

is that fluttering bad?

When you start reaching serious boost levels, yes, compressor surge can be a problem... low boost levels I really wouldnt worry about it.

I could write a nice paragraph too.. but we will use this steves from twinturbo.net.

"An Explanation of Compressor Surge:

The turbine in a turbocharger in its ideal mode is spinning at a very high rate and therefore generating lots of pressurized air that is fed into the OPEN (wide open throttle) intake manifold which translates into more power, but what happens when you take your foot off the gas when shifting between gears? The turbine in the turbo is still spinning at a high rate but now you've taken your foot off the gas and the intake manifold is CLOSED. Now the turbine spinning at a high rate and is trying to push out all this compressed air but since the manifold is closed, that compressed air has nowhere to go. What happens next is that the turbine slows down because of this pressure build-up between the compressor and the intake manifold. Since the pressurized air can't go forward into the engine it heads the wrong way back towards the turbo where it slows the turbine down (compressor surge). After you shift gears and you step on the gas again you want to have the turbine spinning fast so that its producing boost but since you took your foot off the gas and caused compressor surge, it slowed down, so you have to wait for the turbine to "spool up" (spin fast) again. This delay waiting for turbines to spool up is what causes some of the performance degradation that were trying to avoid."
