Blkwdoss @ Ground Kontrol Dyno Day - YouTube

2006 Cobalt SS/SC (Turbo Swapped) - Dyno Pull 2 - YouTube

these are before the quick spool valve so spool is a bit slower than it is now
The turbo isnt even done spooling in these videos when you hit the rev limiter.

1)Type of turbo, Previous 5827, current 6262

2)Power you are trying to make, an easy 550 at around 25 psi


3)Power you are currently at (if known) Car has made 526whp on zzp's dyno (5857 turbo at 30 psi)

4)Your redline, 8000

5)Are you built or not, yes

6)Anything else you would like to add about the setup, current 1/4 mile record holder for the lnf, maybe selling to go twin turbo vette soon

7) Hpt or trifecta, hp tuned by Matt at ZZP

1)PWerks K04+ (aka Precision Big Wheel upgrade)

2)350whp

3)When tuned by Trifecta 349whp 397wtq, I plan on getting dyno'd with Terminator2 tune.

4)7000

5)Stock clutch, stock internals

6)Eventually go VW GTI, Dodge Dart SRT4, Cruze SS, or Focus ST. Basically I'm pretty much done. I'll replace things if they go out, but I hit my power goal and I'm done.

7)At the time of this post, I am currently HPTuned via Terminator2 and have yet to be dyno'd. During the video posted below, I was Trifecta.

Keep in mind I'm 5800ft above sea level and tuned on 91 octane

a little low on the torque, but nice set-up and numbers...looks like you need to feather the clutch and get some better tires to lower that 60ft...thats a low 11 car on slicks all day

I love the valve, it should cut your spool time in half, makes a big turbo spool like a small one.
