Default There's quite a bit of talk lately of variable vane turbine turbos. Has any one heard of any....

that may be used in our application? They're pretty cool. No wastegates, & a very broad usable range; from sensitive, low rpm operation, to very efficient & powerful high rpm operation. I have't been around much, lately, so sorry if this has already been discussed.

Default i really want someone smarter than me to figure out some groundwork on these for the 2.7t

i just dont have the time, money to figure out the first few hurdles. like what ones would be properly sized, where to get them,obtain some for sizing ect.??? if the actuators should move progressivly across the rpm range or move all at once at a certain RPM, if the motronic could deal with the obvious challenge of interpreting flow changes. hell i can fab stuff. i just dont do the whole compressor map flow data stuff. hurts my head

Default I would guess more info would be found on a p-car site

Maybe a start would be to find out how much the p-car replacement turbo is. I read something about a lot of metallurgical research to find an alloy that could handle the temps in a gas engine vrs the lower temps in a diesel application. What engine management is used in the diesel applications? Any with motronic? I don't have any answers but maybe some of these questions could get us started. I for one would like to hear more tech talk on the forum.

Default i heard somewhere in the 2K/ea range......

but i'm not sure if they're even available directly from BW yet. It may be a dealer only item still.
