Dump Valves

Let's get one thing straight, RST's don't need dump valves. They don't do anything for them. No anti lag, no extra turbo life, nowt. On an MFi set up your more likely to have problems than sound like a bus, which is what most people buy them for! Because the KE Jetronic system has the airflow meter before the turbo, the dump valve can draw in air resulting in idle/leaning off problems. Do yourself a BIG favour and don't bother buying one unless noise is all you are interested in. Even on a Cosworth it's only really needed when using a T4 turbo or bigger. It's a big con! Use your money elsewhere.

others will say different when running 1bar or more on RST

 

Spot on.

A dump valve on an ERST is a waste of time and usually causes problems. I speak from experience. I lobbed my dump valve into my spares box a while ago and have never looked back

Even with 25psi of boost the bugger won't be going back on the car

 

I took mine off my cab. The car was gay enough without it. With it, all I needed was a hairband and some sizzors

 

thats all correct when talking about 99% of ERSTs out there...

seriously mate, all they do is make a noise... the car will drive better without it

 

a DV is good for the bearings of the turbo when they are running enough boost.
it could take of the strain from the bearings.

 

The guy who writes on that site chats so much shit it's untrue........................

 

 

 

here we go

 

Gott alove these new smilies

 

Isn't a DV supposed to be good for the turbo's life? So why yes on one car and not on another?
