Ok will a forge waste-gate hold 30 psi or will a fp waste-gate hold 30psi?
or should I buy a MAP Comp-Gate40 External Wastegate O2 Housing (Mitsubishi Evo 8/9
their claim....In yet another installment of our never ending quest for the perfect Evo O2 Housing we have utilized the new, ultra-compact CompGate40 from Turbosmart. If you're having issues with boost control and/or exhaust back pressure is overpowering the spring in your wastegate actuator preventing you from running higher boost levels this product is the answer! We recommend running this external wastegate in conjunction with your factory internal wastegate for the best of both worlds in regards to spool characteristics, boost control and boost capabilities. Simply run a vacuum line to the external wastegate from your boost controller as normal combined with an additional vacuum line directly from a boost source to the internal wastegate actuator and you're all set, no additional modification necessary!

 

bump for your thoughts....

 

Correct me if I'm wrong but, I looked through your sig and noticed you didnt have a turbo upgrade, so if thats true I don't think there is anyway you're going to hold 30lbs till redline.

 

So what are you asking?? will these wastegates hold the boost? sure just put the right spring in it......if you're asking will your turbo be able to hold that boost all the way through the RPM band?? who knows...what type of Turbo are you running?

 

Currently running a 25g ported and polished with 11.5 hot side
I'm currently hitting 28-29psi
In 2nd & 3rd but the tuner is says its the wastegate that is the issue.
Too get a different one if I want to hit north of 29psi.
Then ill exceed 500 whp
So I've already upgraded ft he turbo just need wastegate advise.
Thanks for the replys
Are either one of the wg better then the ither?
