Thats damn impressive. What are you using for a boost control? Can you adjust easily or are you changing springs around?

thank you,  :) i was happy with it, especially with only 34 psi screaming through there.  38psi is where we made 648whp on the dyno.  im sure the hill didnt help my cause much either. 

for boost control we have a three port solenoid.  and all you do is mess with the duty cycle to control the boost.  spring on the wastegate is 17 or 18psi, but the wastegate flow isnt exactly optimal off of the manifold, so theres a bit of creep even on wastegate pressure. 

shoot me a pm on vortex about how many 044s you were looking for.

do you have a dyno plot? i have the same turbo curious where it spools

Any chance you have pictures of your boost control solenoid and hose configuration? could you post up a log of your dyno or anyother run you may have?

I'm trying to see what i've done wrong with my project.

the boost control solenoid is just a three port solenoid that i got from kevin black.  hose comes out of the compressor housing, to the bottom port of the waste gate (where there is a T fitting) and from the bottom port of the wg to port 1 on the solenoid.  top of wastegate to port 2 on the valve, port three on the valve is open to the atmosphere.

the RPM pickup on the dyno was a few 100 rpm off, that fast drop in power up top is actually the rev limiter, lol.  but ya, that was just a hour on the dyno, turned the boost up.  tuned fuel, actually turned the timing down from where it was on lower boost.  and that was that.   

this is a t4 .81 hotside, i think i may go to a .96 over the winter, we will see.

brought the car to the track for its first four passes the other day.  drove it back on the trailer, had fun.

ran best of 11.1@133, best mph i had was 136.8

street tires i want 10's.  with a bit more practice i think i can muster it.

Spring 2012




And finally, fall of 2012 and we have a completed, driving car again.










plans for 2012 season are a bit more power, not that its needed but 700 was the goal when the project began...and why ****ing not right? 

zerb

so, 2012 was a good season, car finally went 10s on street tires.  only casualty was my 1-2 shift collar...hopefully....should be back next season in the spring to give it hell with a fresh transmission and 38+psi cranking into the motor!
