Crashed the Evo Last Night so... everything is on a halt.

What is your opinion on Wastegates? I dont hear a lot of talk about them.

 

What about them. For a stock turbo the stock internal wastegate is fine, as is the stock wastegate actuator.

 

Cool, well it sounds like a Megan might be the way to go...

 

so upgrading the wg isnt a big mod for the evo? I Just remember on the srt4's it was night vs day with different wg

 

Not really a mod that most people do on a stock turbo.

 

very nice list.... lots of information!

 

i seen someone that had a thread going testing to see if it worthwhile to go external wg on a stock turbo. i can't find it though

 

I have seen this done. But with the wastegate dumps now available. Modifying the wastegate from internal to external is more obsolete/PITA. I have had great gains from the O2 dump.

 

what about noise level? aren't o2 dumps usually very loud at wot?

Loud...in a good way

 

Yes, they are very loud at WOT since you have a lot of exhaust dumping right underneath your engine bay. I had one on a DSM which was cool at first but then it just got really annoying after a while so I'll never be getting one for the Evo.

 

yeah i'm trying to make my car as quiet as possible

 

Your choice of downpipes, Megan resonated testpipe, and a Perrin catback.

 

Am I just missing it? How do the crank case vents actually work? Do you remove the PCV? Do they vent to air or back into the Intake? If somebody could help me out. Also has any one actually dynoed them like how Buschur did with the catch can?

 

No dyno results that I've seen, but they're essentially high grade check valves. You can ven thtem to air or back to intake, depends on your setup.
