I do have to say it's crazy how quickly my turbo spools I don't feel any lag at all. My DD is a 2010 WRX and it has 10X more lag.

Unfortunatley I'm uber paraniod about the wastegate noise and want to be able to get on my car more without worrying about letting the world know that I'm comming. I'm going to search for deadzero's thread thanks!

 

hey what happened? I thought open dump was the way to go

 

wholy bench racing batman.

 

BENCHINOMICS 101 FTW

 

I would say 15-20 more hp.

 

Re-circ dump FTW. If done correctly you won't notice the power difference. I would guess you will gain 20 ish hp after the exhaust upgrade. Obviously you may need a few tuning tweaks.

 

yea I'm going to have evans retune it. I really wish I could just keep my mugen restrictive exhaust and still recriculate it to stay super quiet but I guess it will be good to actually hear a the engine a bit over the woosh pssss of the trubo and blow off

great article: http://articles.evans-tuning.com/category/turbos/

 

What's your boost now?

 

7 wastegate spring low boost
15 highboost

In looking at all the dyno's from Evans of FR kits with the GT30 it seems the guys who riun 18 ar hitting the 500 mark. I may go that route. I am tracking this car hence the low 7lb wastegate spring.

 

why the dip in power from 5k-6.5k?
