PDXTUning has done all of the tuneing and motor build. i am not a professinal engine builder, so i will not take the risk with my own car. but i have donne a lot of work to my car.

as for the heads, i am unshure at this point. but i am considering it. all depends on $$$

 

I don't understand why you are jumping to the head gasket as the cause of the problem? Did your car over heat? Check the turbo for shaft play, when they go, it is obvious. Based on a a sudden plume of smoke, the fact that you found your catch can full etc, it would seem to me that you should drain the catch can and fire your car up. Basically, process of elimination, easiest stuff first. Hope you are not getting taken for a bunch of unnessesary labor

 

nahh man.

by process of imlimination we found it was the turbo. so the 35r will be on soon.

 

Nice. Good thing you dont have to pull the motor.

 

Yeah. Really poor design IMO. They did it so that it would get a LEV rating. One of the requirments is that the cats have to be operating (read HOT) within a few seconds of starting the car. With the turbo in the way, post turbo cats don't heat up fast enough.

I actually have an catless uppipe sitting in my garage waiting to go in my wife's WRX this weekend. I have ~60k miles and I'm getting nervous that it'll break up soon...

 

Deffinatly. i have replaced a lot of turbos in wrx`s and people really dont seem to figure it out. a cat is BAD befor the turbo. who knew?

well hopefully i will have a mild tune befor the 4th of aug. that way i can do the hill climb that cause the turbo to go, lol. i must go back. very awesome roads out there.

 

well just got the word. car should be put back together by this afternoon. seems the turbo went due to the fact that the BOV could not vent enough air fast enough, thus creating compressor surge. Dustin has yet to exzamine the turbo to see exzactly what went wrong with it. but i am sure i'll find out soon.

 

well picked up the car tonight..

470whp on 92* w/~~50/50~~water/meth

i will post the graph tomorow, thought i would let you all know.

it is damn fast

 

nice **** dave cant wait till i get back hopefully i can have a run or two with you at the track

 

What boost levels? i saw your meth set up last weekend as i was cruizing around behind enemy lines looks good.

 

Why 50/50 mix?

 

50/50 mix because i would rather not have to worry about the seals on the pump. and the power gains from a 50/50 VS a 100% meth tune are not huge, there is a differance. but for me i would rather not have to worry.

boost was @ 23.5psi

 

That's a bunch of crap. I run ~30psi with only 1-1.5 counts of knock on straight meth. 7 psi is a huge difference

 

Straight meth is the way to go IMO. Im not sure why you would worry about the seals on a meth pump....

 

I am pretty sure he is using the Aquamist system. Aquamist recommends no more then 50% mixture of alcohol with their pumps. They do make a seal kit that will allow an increase up to 75% mixture of alcohol. They do have a new pump in the works that will allow 100% alcohol use.
