Turbo news 9/15
Just another turbo update for the community and some info we collected. The (01) wheel and GT40 wheel were tested and put head to head a few weeks ago. We didn't want to post anything till we had something other then SOTP. Keep in mind these wheels are not made by us.

Anyhow both units were tested with NO wastegate. So what it blows is max for what the compressor wheel can make. The margin other then peak #'s was still on average 30rwhp/70rwtq.

The test unit is a custom unit we built for a 03 5.9 Cummins diesel. All we changed are compressor wheels. GT40 wheel came straight from GT703457-2 and both wheels are same basic size on inducer and exducer.

498rwhp/1088rwtq@31psi- GT40 wheel

570rwhp/1280rwtq @57psi - (01) wheel

BTW, the (02) wheel is next up on swapping in. I fully expect to see 600+/1350rwtq broken by a single turbo. Keep in mind this is on a diesel which requires a much higher volume of air and is the ultimate test for a turbo. EGT's were reaching ~1750
 
What is an (01) wheel? Who makes it? and the (02)

That much flow from only a 63mm or so wheel? :eek:
 
I am trying to find out more.
Sounds nice for a twin set up!!! :eek:
 
You think i want to run 57 PSI on my cummins and have it last 10 years?

Hell no, i dont want to oring my setup, i want to keep this longblock as long as possible.

I show you a trick or two :biggrin:
BW ;)
