Advantages of external wastegate


Recommended Posts

External gives better, and more consistant boost control.



Also gives the screamer pipe, which is probably why most people choose this route!



If the noise of a screamer isn't to your taste, it can be recirculated into the exhaust and will sound no different to an internally gated setup.

I'm internal but going external waste gate for the benifit of no boost creep as that is no1 fucking annoying and no2 can shaft ur engine if running td04 and it creeps to high

TD04 probably wont creep, as the problem with a CT9 is the size of the wastegate

thats what causes creep

Yeah main reason most people run them on CT9s is too prevent boost creeping issues. And also for the noise.



Ive been externally gated for about a year now and i wouldnt go back to internal gate anytime soon.
