Neither of those is suitable comparison for the -8.

One is a dual scroll turbine, the other is a ball-bearing unit, each with different characteristics than our beloved GM-X series.

Cannot imagine why TDG did not clarify that...............

For ours, some shops 'shave' the turbine snail and wheel, claiming improvement, but actual measured numbers have yet to be posted as proof for verification.

Cant sleep so I thought I would share this with you.......


That map or diagram is chinese to me.

But I can get 22psi out of my current setup with my turbo master cranked to about 1-1 1/2".
I can hold it at will too, I'm not talking about a spike at that psi, I can actually hold it. When I had the vacuum setup, It would spike about 20ish before dropping, But now I can hold the 22psi at will. I bet if I cranked it some more I might get a little more, but I didnt try. I dont know if this is significant or not...I just thought I would share since I could'nt sleep.
And to be honest...it really wasnt that spectacular...It was funner...but definatly no corvette.

BTW, I leave it set at 14 psi max, and I usually try to keep it under 10psi while driving because of the friggin fuel prices. The 22psi thing was just playing one day, so no one trip out on me. Rambling done...good night.
