will there be boost creep issues with the .64ar running 2.5" all the way back, no cats?

SPOHN · 10-07-2013, 05:37 PM

External are awesome but the 3" downpipe is not going to mate up to your exhaust. Will need some modification.

megalapagas · 10-07-2013, 05:46 PM

Yes mike mentioned that and just the thoight of cutting my exhaust and welding a 3" flange to mate is just Pure Suffering and Agony to my soul :/ but is it possible and what would go for external or just replace exhaust?

Welding a 3'' flange is nothing. Not sure I understand your last comment?

megalapagas · 10-07-2013, 05:46 PM

BTW I'm 7AT just to clear things though....

megalapagas · 10-07-2013, 06:14 PM

Yea my bad am typing through android at work lmao, which would uou go for though replace exhaust or go for external and weld a 3" flange?

SPOHN · 10-07-2013, 06:22 PM

Weld a flange. Easy, simple, and not costly

megalapagas · 10-07-2013, 07:56 PM

Awesome then ill hit up mike AGAIN lol to change the setup

Mega are you doing your install yourself? You need to let me know if your ever coming into central Texas for a show or something (San Antonio) so we can meet up.

No I'm not I'm gonna have a local shop here in mcallen called KMP do it for me I actually did wanted to do it myself but its my first Boosted car and I seriously don't want to be the one to blame that I messed it up lmao xD and Ive never been to a car show/meet in san antonio though I don't have alot of info on that :/

megalapagas · 10-08-2013, 05:19 PM

Yesss!! Everyday you learn something and I finally got it right lmao so then I'm fine with my Exhaust setup that I have in my Signature its all Non-Resd with the .84 internal no need to change to external or would there be a liability on boost creep still? Reason I ask is I rather have room for safety than having trouble down the road

Boost creeping is fun! More boost!

Go with external wastegate. my boost gauge was reading 8.8 PSI while the internal wastegate spring was 7 PSI.

1.8 PSI of boost creep is a lot if you ask me. Im not so sure if going with .86 housing will eliminate the boost creep or will just minimize it (which is still not good)

So just to be in safe side. go with external wastegate. you will have better boost response, better flow, more power, and last but not least, it will extend the life of turbo.

Yes you heard me right it will extend the life of turbo and will give better power and more power.

Please watch this video to learn more about external and internal

Yep. Other than cost, external is always better.
