who makes the fastest spooling turbos?
What makes these units claimed to be the fastest spooling different in design?
Sounds like the old "Voted worlds best tasting Cup of Coffee" syndrome.
Just need some links to some technical detail if you have them.

How does this compare to the new S91, is the S91 ready yet? Where do the S Series fit in as far as fastest spooling goes?

It is a little odd to me that variable-vane turbos haven't reached the performance industry yet. At least not that I have seen. They have been out for a couple years now on the Duramax's and seem like a great idea to try and get more of the "best of both worlds" in a turbo. Super fast spool and high flow in one package? I guess maybe the production costs are too high on them? No one making them thinks there is a big enough market?

also on a gas engine where you have more heat in the exhaust gasses. these can cause inconsistant oil presures causing the vnt to be evem harder to set up.
but it will come in. ball bearings have, so it juts takes time!
orange 88, well as longranger is using a T88 rear mounted on his 408, this new one would be even more driveable/build more boost on the line!
thanks Chris.

We get to rebuild quite a few VNT's from the Powerstrokes. They are pure junk. ALOT of them fail, cause the vanes with time tend to stick due to carbon. Only way to fix that is to remove the turbo and clean the back half. You can't expect customers to do that like a regular maintence item. Way to difficult and time consuming.

Did anyone ask you anything?? You like to hear yourself talk WAY too much ProStock

is there anyway to make them more reliable/easier to maintain?? do you think the Porsche units will suffer the same? do you have mayny from deisel cars, if any??
thanks CHris.
