Mike Kuttschrutter was running a compound setup up until a while ago.

Mike beat me to it! As Salomon said, all these use two turbos but all are very different and have there own advantages and disadvantages.

Ya, the compounds are for early power and a near linear torque curve. IMO a better way to go for that earlier spool and still big topend is a Holset VGT turbo and this controller: http://www.youtube.com/watch?v=7EDCKvkQoaEI kinda wish I went this route, but we will see how the compound setup does first.

After speaking with one of Ford's lead Powertrain Engineers this past year about variable vane technology, it seems that it is only now starting to become viable for gas engines, as the temperatures of the exhaust gases are significantly higher than diesel applications and have caused significant reliability problems. They (the industry) has been working on coming up with many new materials/alloys that are supposed to be able to withstand the heat reliably for the life of a vehicle.

the only reason I knew about VFT's is because the 1st gen Acura RDX (2007-2012) comes with one. It's a 2.3L 4 cylinder that produces 240hp and 260trq. you can hear it spooling at 1000rpm under maybe 10-15% throttle. neat stuff IIRC, it runs 14psi up to 4500rpm then tapers off to 9psi. I wonder if an MBC would correct that tapering "issue" I know Hondata makes a chip and for roughly $300 (sending them your ECU), you can get an extra 60hp bringing the RDX to 300hp, prob 320-330trq. edit: and this is a GAS engine, so it looks like this may be the way of the future...?

Like I said, it has only recently become a viable option for gasoline-engined vehicles. Reliability was always the main concern, so I guess they've come up with a good solution. That being said, I would NOT suggest someone try fitting a diesel VFT/VGT on their gas-powered car as it would not end well. To use a turbo with this technology you need to use one developed specifically for gasoline applications, of which there are few and they are really goddamn expensive.

Back from the dead! Had the compounds whistling away on sunday night around town. Only sporting 15ish psi at the moment. But I am confident this little setup will be seeing 20+psi of boost by 3000rpm. The feeling is quite amazing. The small turbo hits the 15psi mark no problem, but as the larger turbo begins to take over and screaming like a jet, it feels as if you are continually boosting, even though it holds at 15 the entire time . I will post my logs, and results as my tuner and I start digging into this further and getting that boost turned up.

Damn Mike! I didn't know you put the compound setup back on! Very cool!
