not 5 as I first suspected!

Was that because of the drawing Jamz?

just off on a tangent about a turbo bike. has anyone ever seen a bike fitted with a dump valve that would be extra cool wouldnt it.

I'd love to say it was... but that drawing is probably better than I could do...

The one with the intercoolers added is even better!

Yeah a supercharger can be fitted with an intercooler or a charge cooler.
And hasn’t the ghost rider's yellow 499 BHP busa got a dump valve

GR busa has a turbo, cant say ive ever heard a dump valve blowing off in the films tho.

our chipped integrale 16v had a dump valve .. mmm ,,, i know its sad, but the noise it made just encouraged you to nail it through the gears at any given opportunity..

silly car ..

loved it.

love driving my mum's fiat coupe 2lt 20v turbo, very much under rated car's can pick them up for about 1k now

then again insurance group 19 makes them abit expensive

I used to have a daily tussle with one on my morning commute!

First time I met the bugger I was doing 120 and he came absolutely flying past me!

We made it a bit of a game after that to see who'd keep it nailed for the longest down that bit of dual carriageway!

Very quick cars - a great match for a ZXR400!

Eee, I miss him!

[deviant]

whether the original idea that jamz posted was a joke or a genuine (wrong) idea, it's certainly spawned some entertaining pseudo-science in response.

however I haven't got time to point out why in any detail. rover220 is right in almost all of what he's said though.

you can use either a intercooler or charge-cooler with a turbo too.

[BANJO]

Just to be boring turbos need a dump valve, all the factory ones are re-circulting no noise and for the emissions, the dump valve stops excesive pressure in the inlet/turbo when the throttle is shut, as you can imagine things would soon go bang

another incorrect statement.

not ALL turbos NEED a dumpvalve. for instance, a nissan 200sx s13 comes without one as standard and that uses a garrett t25 turbo. they are many others too.

i ran without a dumpvalve for over a year on my t25 and later on my t28.

[stu71]

my mistake thought petrol tubo cars did soz or some kind of bypass system not just the waste gate

[superman]

a dump valve wont make your car or bike go bang ainyway. they make the performance better and to have the turbo you need to make critical changes to certain things dont you?

OH that busa sounds awsome i would love to ride that for a day imagine how cool it would be burnin someone off then just to rub it in you hear the dump kick in
