mine certainly feels that way, not sure if its actually thorugh the driveline, or just vibration from the flutter itself... my flutter is pretty badDr.Outback wrote:Can you descibe the sound? I get a small pulsation through the driveline when I'm in fourth realatively low rpms. I'm wondering if what I'm feeling is what your hearing.

I didn't elaborate very much.Project_Legacy wrote:how low in RPMs are u talking about? if its too low i think u jus needa downshift. the sound i hear is like.... i mean i can tell its the turbo cuz its pretty loud. but i dont get any pulsation thru the driveline...
I usually feel it when I'm at about 2100-2400 rpms in 4th, and the turbo is just beginning to spool up climbing a hill. The engine isn't laboring, I know that. I also feel it in 5th on the highway, or going up a hill, accelerating from cruising speed with light throttle application. It's just a small pulsation, power doesn't seem to be affected that much.
seems like there are a lot of different degrees of it. i get it in every gear and RPM with anything above 0psi its a loud clicking noise and pulsation, boost bounces between 9.5 and 10psi. i assume because i have a crappy bellmouth downpipe that boost creeps alot and its the boost control trying to counteract it.
