question, whats that short sharp hiss sound when he changes gear? the turbo?

 

Thats a twin VR6 mate. One in the front and one in the back

The the little his is the wastegate/dump valve

 

ah, i did think it was fairly loud!

 

i always thought twin turbo ment it just had 2 turbos??? Or do you know this car from elsewhere lol

 

NAh man.
2 VR6 lumps...
2 turbos, 1 on each engine.

One engine in the front, one engine in the back...

 

from (winey gti) pics at this years gti international at bruntingthorpe:

Still an amazing car! Been around for a long time now...

 

that will be B16 DUB (big dub)

I've got pics from inters couple years back, with it there

nice to see it was still drawing in the crowds, you see how many people ran to the strip everytime it came up the line 0-60 in 3 seconds was it??

 

it's class!

must be sooo loud and hot inside though!

And surely complicated to get it working?? Timing? changing gear etc??

 

Thats the blow-off valve making that "chirping" noise. Its a release valve to prevent excess spooling/boost pressure to escape between shifts. Without it, the turbos would practically blow themselves up. Twin turbo setups can have 2 turbos on 1 engine. Eg. Nissan 300zx tt(twin turbo) has one on each side of the v-6, hense, exhast driven turbines.

 

You can hear a very obvious "boost" release as he crosses the finish line and starts slowing down.
