Turbo Flutter

[factoryblack181]

hey guys. i was driving around today and i was on the highway and decided to step on it, went from about 65 to 80 (somewhat) and when i hit the higher rpms it sounded like the wastegate wanted to release but all it sounded like it was doing was "fluttering" like it was half open and closed. i just had the pyro installed the other day and i was wondering if maybe the hole that was drilled is leaking and not causing enough pressure? just a guess. help me out guys! thanks!

sounds like turbo surge to me.... its normal on a stock turbo... their are a couple of ways to clear it...

ATS housing or a upgraded turbo... some say that a WW will cure it but im not convinced....

alright so its normal? at high rpms? it doesn't happen in the first gears. just when im about 70 mph. and when this sound happens should i let off?

well its sort of normal... but its not good for your turbo....

i had the same problem and the wicked wheel worked for me. it was not as expensive as a ported housing and was easy to install if you are familiar with that stuff. i plan to add a ported housing though so that i have a true 4" in and a 4" out on both sides of the turbo. it will also make the turbo whistle a little louder

ok. so to compensate for not wanting to spend money at the moment, how would i avoid the turbo surge? just let off or what? especially if i need to go that fast

if you are worried about the dollars, i would recommend the whicked wheel. i cant remember what i paid for it at the moment but it was im sure around 75 bucks. it took care of the surge problem for me. and i do a lot of towing, for camping and my farm.

well im really really tight on the money right now. paying for school sucks as you probably know. would just letting off solve it temporarily for now untill i can get a WW?

letting off for now would prob be fine. from what ive been told only long term surge can eventually damage yur stuff. you can find that wicked wheel though at www.dieselsite.com and they run 79 bucks my bad! i was close. before i change mine it would only get bad on the hills pulling kinda hard.
