Can you get a standard 2ltr turbo to chatter?? Sold my escos and got a standard uk wrx classic p.reg my escos used to chatter its nads off and i loved the noise,can you get a scoob to chatter also??? It had a dump valve on it at the moment but i just hate the noise of them and want it gone.

 

Blank off the dump valve pipe work bring on the debate of if it damages the engine or not - its been covered loads try the search should bring all the posts up hth jon

 

Will do cheers

 

Fitted a Forge re-circ valve to my type r and it chattered like a good un afterwards, not to mention run a million times better than with a vta.

 

If you are getting compressor stall after changing your dumpvalve, the reason for this is because the valve is not opening - presumably due to too strong a spring for the amount of manifold vacuum your engine creates.

The net effect is the same as running no DV at all. So if you're getting a lot of this, and you're not running a turbo that is known to be tolerant to it, it might be worth looking at the spring tension - or whether a weaker one is available.

Oh, try this thread Picky, probably answers most of your questions: https://www.scoobynet.com/general-te...ve-delete.html

 

Which model scoob do you have Picky? The VF series turbos don't seem to like running without a dump valve because they aren't as strong as the TD turbos. I have a Sapphire Cosworth and I run no dump valve and my sister doesn't run one on her 95 WRX but they don't make the same noise The noise with no dump valve on a Cosworth is much nicer than the WRX.

 

Ive got a uk spec wagon classic,my escos sounded lovely without the valve so just wanted the same type of sound .

 

Cheers for the heads up, but not my problem anymore, sold the car and the new owner has drastically changed the spec

 

Trade it for another Cosworth then

 

Very tempted mate i really am

 

my escos had same noise and my mates saff.love and miss that sound
