Just wondering if anybody is running any setup like this, or know of any companies looking into doin this. Just tryin to free up some xtra HP The srt-4 guys have been doin this for a while with nice gains. Thanx in advance-Gary

 

Yea. I don't think anybody with a K04+ like we have, have done this upgrade... Because our wastegates are internal. But I may be wrong... Roll around the Solstice forums they have been around longer, and probably have messed around with stuff like this. Let us know if you find anything!

 

We set one up like this for testing. It's sitting here if you want to purchase it.

 

what kinda gains did you see with this set up?

 

Also curious.

 

Shoot me a PM with the info. Very interested

 

but how? running internal wategate and external wastegate

 

I would imagine the internal gate is welded shut and they made a hole in the turbine housing and welded a flange for an external gate. Still don't see the point of this on a stock turbo, if you want to hold more boost you can always get higher pressure actuators and modify them to fit easily.

 

Is this like "clipping" the turbo?? What is gating

 

Very little change if any in spool time, max boost, or HP when running a 3" exhaust. If you have a more restrictive exhaust, you can benefit from the open gate dump. You also can't use ECM boost control anymore unless you have access to the boost control duty cycle tables.

 

I think its pretty pointless in the end, to be honest. The internal gate works quite well for the amount of flow the stock turbo can produce. Might be good for looks, or to say you have it, but not so much for performance gains, as the money spent could be used elsewhere for bigger gains.

 

Yup, which is why we didn't take it to production.
