wastegate chatter??
 

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 :norty:

Trade it for another Cosworth then :norty: :lol1::lol1::lol1::lol1:

Very tempted mate i really am :lol1:

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