external wastegate on a DDP?
- Thread starter ml43

theres no point of doing that...if you want that route then get an aftermarket manifold with an external wastegate
It might have a hard time building boost, the length of the runner might cause issues...
Not to mention this is another "Why?" mod where there would be zero gain except for lightening your wallet and being "different."

mmm good point about the runner length
arent external wastegates better, because you can choose the size that best matches your turbo/tune, and is far more consistent? no?
and it wont waste the ddp design if you atmosphere dump the external gate
nm,
seems like evo X guys are already doing this

The turbo they use has a different flange, theres nothing to leak there because its two separate holes in the flange on both the turbine housing and the downpipe.
Seems like a little much for stock turbo and all that. I dont think it would be worth it. The stock internal gate regulates boost without issue.

The only thing I can see running an external gate for is to run more boost than the internal gate would allow. On our cars you're blowing nothing but hot air before that point...
