Chatter or tsssssss
« on: 11:53, Fri 14 December 2007 »
What do you guys think is better? the turbo 'chatter' or a dump valve?

also how do you make a turbo chatter? is it just by removing the dump valve?

thanks

I prefer DV sound. But from time to time i block my DV to hear chatter.

Chatter is sound of turbo flaps when stop turning. You get that sound by fitting mushroom air filter instead of air filter box (DV also needs to be blocked).

Yeah, they are not good fit for GTT if you place them any near the turbo. Best thing is to switch position of the header tank and air filter box. Than you have better cooling and cool sound 8)

I have a HKS mushroom filter  :wink:
Mine sits where the standard intercooler was & sucks in nothing but fresh cold air  :lol:  8)

Nice one. Gonna fit mine on same place as soon as i mount FMIC. Think that there is no better position for the air filter than that, only problem is that you need to get bigger IC and place it in the bumper :D

if you are pushing high boost its a bad thing to do away with dv as you could smash fins from back pressure :?
turbo whine is mighty fine

Been told this is bolloc*s & i have to agree, i've had my car with no d/v running 1.5 bar for nearly a year with no probs ;)
If it's the ceramic turbo's that some skylines run , yes it can be a problem.
It's just a gimmick from tuners to sell d/v 's ;)

have to disagree pal owned gt turbo,s for 12 years plus, and never had a turbo blow up or shatter a impellor blade BUT they do wear a lot faster than if you were running a dump valve . chatter is the compressed air being force fed the wrong way through blades thus causing it to stall hence the chatter (chopped up air exiting wrong way from turbo)
do you not think this will cause excessive load and also significant wear on the shaft ????? :shock:  :shock:  :shock:  :roll:

i also run a stage 3 cossy @31 psi on a t34 with no dump valve (blanked off) as i prefer the chatter to a dump valve
and have already had two turbo,s in last 9months due to this (both times sloppy shaft)
car is maintained a1 no expense spared so is not an issue

also lost count on how many turbo,s have gone through on my gtt (t3) as i run no dump valve on that runs @26psi

you may just be lucky but i disagree on your statement mate
oh i also build turbo,s for a living before im shot down in flames lol  :wink:
