"turbo fart"

[stump0331]

i posted this in the tech files but wanted to see if anybody had anything to add


ive seen several post asking what the chugging sound that come from under the hood after letting out of a heavy throttle, this is backed up turbo pressure that is release back through the intake, it is completely normal and this doesnt mean any thing is wrong it is also more prominnent with trucks that have after marker "more open" intakes but stock intake can still do this. herea video i did of my truck in which i did the "turbo fart" 3 times in 4 attempts you can hear the rpm's increase and as i let out of it you hear the chug-chug-chug sound

and i know i know my winshields cracked

i dont think i have had mine do that going down the road, but most of the time i have the radio up

the first time i heard it i freaked out i thought something was loose, i even made an extra bracket for my heat sheild around the intake, but then i found this place and learned better

i have heard mine do it if i stage it up and let off the throttle, i was like what was that, me and my buddies all looked at eachother, so i rolled the windows down and tried it again and realized it was air

Yeah....at first I thought I had a BOV somewhere that I couldn't find. I do it on purpose when everyonce in a while. It's fun!

Ok, Somebody Educate Me A Little. I've Been Told That Is Hard On The Turbo. Is That Right Or Wrong? I Know When I Worked At The Dodge Dealer We Had Several Customers With Those Inline Motors That Would Do This Under Load And Was Told By A Couple Of The "old" Guys That It Was Bad And Would Trash The Turbo.

ive had several techs tell me its harmless

Turbo Surge is hard on the motor...(You'll hear it while your underload.) The BOV "WHOOSH" is heard when you let off of the throttle while the turbo is spooled and making about 15+ psi...this is basically harmless...it's just excess pressurized air. Surge is the force of the pressurized air trying to get OUT of the turbo through the intake side WHILE your still under load.
