Hi,

 

I have heard what i think they call wastegate chatter on some cars when chaging gear and to me i think it sounds better than ya standard whooosh noise from your dumpvalve.

 

Does anyone know is it possible to achieve this sound on a 91 UK 300zx TT, would you just need to upgrade the Wastegate or does it involve more than this? The car in question is completely standard.

 

Tnx,

 

Dan :cool:

that noise is turbo stall, nothing to do with wastegates, remove the recirc valves and you'll hear it, turbos wont last 5 minutes though.

Sounds to me like he is on about external wastgates,if you are then yes you can achieve it!

the noise like this car makes you mean?

Lots of cars don't have DV as std, they are not necessary.

i always thought that "chirping" was a type of re-circ - it's very notcable if you watch the Rally

The rover turbos do come with a recirc valve as standard so i doubt that sound is turbo stall.

I know the sound, I used to get it on my R5GT Turbo before I fitted a dump valve.

Sounds a bit like Hannibal fa fa fa fa fa ;)

thats a honda VTEC thats been turbo'd mate, notice the tacho going off the end of the clock :p

if it's the noise from wastegates that u like u'll need 2 wastegates and two manifolds

Yea i must say i thought it seemed to rev much better than my old rover turbo, but i don't normally have the balls to try go past redline anyway!

2 wastegates and 2 manifolds? Cant keep the existing manifolds then? When you say wastegates you mean uprated wastegates? if so how much are looking at?

 

That is the sound i was after though yeah, reminds me of the supra in the fast and the furious, that has the same sound.

Well if it is, they've installed it into a Rover - look at the steering wheel and controls!

 

If the noise is from external wastegates then surely you will need new turbos, manifolds, downpipes and wastegates £$£$£$ :shock:

 

 

I love the noise but not that much!

nah jesus in that case think i would stick with the dump valves!

yes its a rover, one of the ones which came with the VTEC motor in, then he turbo'd it to make it more mental, top job imo :D

3.4K I think the wastgates are about £800.

Jesus....well be worth it mate, all your need then are some NOS blow-off valves! :-P

 

Try and post me a sound file of it when you get it all done.
