right want do do this mod...
as missing the sound from the filter....
but who has done this,and is it better with a fmic
or is it ok with a tmic.....
car is a v4 type-r if anyone has done it to one of these..
all advice welcome..
cheers chris

 

I have no DV with fmic and sounds awesome.... turbo noise, actuator and filter, whistles, sucks, flutters etc

 

The smaller the turbo, the more often you'll run into compressor surge on lift offs, compressor surge hammers the thrust bearings and can lead to premature failure (If using a Garret, everyone says you MUST use a 360 thrust if running into surge) that said the TD's seem fairly robust, the IHI VF's aless so though (not sure what you have) when I blanked mine I couldn't drive it without running into surge, but then I have 0.8bar of boost by 1800rpm.

I have no dump valve on my car, fmic and 20G, all good.

 

i have a vf24.
and running standard 1.1bar of boost..
just love the sound of the filter flutter...
so still dont know as a new turbo aint cheap,......
or i could just get it built to hybrid spec,ie:360 bearings and all the rest....
how willi know if it hits a stall,will it just shut down?????
cheers chris

 

I would only run no dump valve on a good condition TD series mate, pretty sure most of the bearing VF series wont last long.

 

did this on mine (vf35), got all the flutter noises not as loud as i thought but my god it was laggey when it did eventualy spool up the skin still stayed on the rice pudding so standard dump valve back on now come to the fact vf's dont like it

 

In all honesty it's not worth it unless FMIC/induction, could hardly hear it on my TMIC/Panel before FMIC route.

 

i have a blitz sus...on there so got the i/k
but mind says dont do it,think of your turbo.....
but heart says "go for it baby"...
but my misses says dont you dare...........
i like being dared as you just have to do it..
still in two minds..

 

You could always record some WRC engine clips onto a CD and play them on your car stereo. All the noise you want and no risk to your turbo (or your relationship).

 

As mentioned TD series allegedly tough enough to go DVless.

VF's up to VF29 = need DV
VF30 > on = DVless okay

Courtesy of JGM's wisdom.

 

My VF35 performs a lot better without the DV, especially on fast full bore up changes, chatter not that loud either..

My VF35 is heavily ported/throat-ed, so maybe that's why it doesn't surge, still noisy though (whistles) if I just plant my foot off boost. Can't complain at 1bar by 2700rpm and 1.6bar from 3000-6000rpm (1.3-7k)..

 

That's just bootiful.
