Hey I just got a new tune on my truck and im getting some turbo bark when im letting off the throttle. I was just wondering what i can do to help prevent it. Is a BOV possible? or would that even do anything?
Turbo bark is horrible for your turbo.Is a bark bad? I think it sounds awesome!
Wide open when i let off quickly its pretty loud. But its a tune from HP Tuner, around 200horse tunewhat kind of tune? how bad of a bark under WOT? and left off?
Sounds like the first, but really only when my foots through the floor and i let off quickdoes it sound like this
YouTube - Tommys Turbo Bark
or like this?
YouTube - Duramax turbo bark
if it sounds like the first video it is VERY BAD!!!!!!!!!!!!!
it will ruin your turbo fast
Don't let off fast you need to ease off the throttle. even a 50hp tune you can bark the turbo if you go from WOT to nothing.Wide open when i let off quickly its pretty loud. But its a tune from HP Tuner, around 200horse tune
hope you set aside money for a tranny runnig that tuneWide open when i let off quickly its pretty loud. But its a tune from HP Tuner, around 200horse tune
No i dont actually. Its not gonna stay on it, i didnt have time to get a safer tune set up. But i mean ill be getting a safe tune on it this weekendhope you set aside money for a tranny runnig that tune
I see that as an opportunity to upgrade Jesse. :drinkIn the mean time, just let out of the throttle SLOWLY. Otherwise you'll have 25+psi of boost spinning your turbo in the opposite direction when you let off the throttle. Won't take too much of that abuse to break the turbo shaft, then you're really screwed.
Well its harder to bark a VVT turbo.lol i herd a duramax make the bark like the first video and it crack his compressor housing..sounds like trouble..also sounds cool in a way. but i am running around 185 and i can go from wot to nothing and it doesnt bark at all it will only bark if i hold the break like a boosted launch and not take off but left off the throttle fast.. i didnt know it was bad until DGKPOWR sent me a pic of his "bark mark"
You have a VVT turbo. The LB7 turbo is the only one in the duramax line that has a wastegate on the turbo. Every Duramax after that has been a VVT.why is that? and idk if it was vvt or not.
