That appears to be a significantly expanded turbo map. Perhaps
Garret invested in some high buck 3D simulations software.

Which trim do you recommend Chrissi?

LOL, I'm just a newbee dummy at this; I was throwing it out there to ask you
guys.
Based on Cliff Manzke's calcs he comes up with a corrected airflow of 31.7
lb/min at a pressure ratio of 2.0.
Looking at the GT35 76mm, 52 trim, 0.50 A/R (red graph) that puts it right in
the middle of the sweet spot, yes?
Are Cliff's numbers generally accepted as good?

Looks good to me Chrissi. You guys are being very conservative
as the GT35 is rated at 260 HP to 510 HP. Looks like Garret
adopted ball bearings with a vengeance. I wonder if they are
the silicon nitride variety. 10 times more durable is quite
a claim.

The new catalog looks great. Greatly simplifies choosing a turbo.
What does the GT35 cost and who are you buying it from?
Any idea what the turbine wheel is made from or are they
all Inconel now?


The GT35 matches the specs of Greg's as close as I could find in that book without going to a
hybrid (extra cost)
I will try to find out the materials used and things like inconel turbine wheels soon.
Before I commit to that one I need to have the shop's "experts" look at the matchup on tuesday.
This is from a performance shop in Australia. As it is in the catalog it would be $1250 US
including shipping but how much a hit would it take on import duty?
