I work at GM Powertrain HQ. You should see some of the stuff we're working on! -

Re: GM Developing Twin Turbo V6 Eco-Boost Fighter
If GM obtains about the same horsepower-per-liter as the EcoTec turbo/DI 2.0 (~130 hp/l), the GM 3.0 will produce around 390 h.p.
Of course Ford's initial EcoBoost engine is tuned more for quick response and a flat torque curve than maximum h.p. And reportedly FoMoCo is working on "Project Bobcat" (supplemental direct ethanol injection), which would easily crest 130 hp/l. Former FoMoCo exec Dr. Neil Ressler is involved in Ethanol Boosting Systems, L.L.C., the holder of key patents on the EBS process. http://www.ethanolboost.com/
It's unlikely that the current regime at Ford is going to get beat in a horsepower war. For example, a recent chassis dyno test of the Coyote-Powered 2011 Mustang GT yielded the following:
But the overwhelming concern is probably future compliance with CAFE standards. These turbo V6s are clearly aimed at V8 territory. And some experts predict that even V6s aren't going to be very common by 2016. http://www.autonews.com/apps/pbcs.dl...303229994/1186 & http://www.autonews.com/apps/pbcs.dl...303229992/1186Inside Line's tester reliably belted out 395 horsepower at 6,600 RPM and 365 pound-feet of torque at 4,350 rpm. That's at the wheel, natch, and since IL estimates the 'Stang sees only an 11% to 13% driveline loss thanks to its stick axle, the car is likely making somewhere between 438 and 446 horsepower at the crank ? far more than the advertised 412.
This should come as no surprise to anyone, especially Inside Line. After all, last year they did the same thing with a 2010 GT500 only to learn that - surprise! - it was underrated. (Their tester put down 511 horsepower at the wheel. The guys figured the number at the crank to be around 570 horses, not the 540 advertised).Comment

Re: GM Developing Twin Turbo V6 Eco-Boost Fighter
I'm admittedly not a big turbo fan in production cars, but my bias is founded in personal experiences that are admittedly now somewhat dated. There was a time when it seemed like you either "got a good one" or you spent a lot more quality time than you cared to getting to know your local Service Manager on a first name basis, and reading the fine print on your powertrain warranty.
Ford has apparently committed the EcoBoost motor to Police service in the Taurus, and those will hit the streets for real soon. That's about the biggest trial by fire you can imagine. No one does a better job than cops do at finding and exploiting weaknesses in vehicles. My gut says two turbos, even de-tuned, won't survive 100k of Police duty in acceptable numbers. At the same time, this will be the best opportunity in the world for Ford to gain valuable feedback on a new design and implement any fixes that are needed.
As far as GM tossing hair dryers on the VVT motor, I guess it was inevitable. At 300ish horse NA, the boosted results could be astounding. I've driven two cars with that V-6 in it, and found it to be likely nothing else. Cam phasing changes so much.
So, are CAFE standards based upon what you actually build, or on what you make available?Comment

Hopefully for use in a RWD chassis!? Maybe that motor in a new RWD Buick model ? Maybe retro styled like an 80's mid size coupe? O ; One can only hope.Originally posted by farmingtonComment

540 hp and still can't get out the 12s
bloatComment

Re: GM Developing Twin Turbo V6 Eco-Boost Fighter
1. A Chevy guy shouldn't be talking about "bloat," considering all of the Earth-crushing weight of 201x Camaros!
2. Hooking up the 570 h.p. is the real problem. Plenty of prepped GT500s are in the 10s. At least one or two are in the 8s on factory long blocks.
3. 2011 GT500 will be 130 lbs. lighter (aluminum block).
4. Buy 'em while you can get 'em, because by 2016, any new car with a V8 (not to mention a SUPERCHARGED V8) is likely going to be in very limited production and carry an exotic-car sized price tag.Comment

Re: GM Developing Twin Turbo V6 Eco-Boost Fighter
A Z06 weighs less than a Focus? Interesting, because MSN Autos says a Z06 weighs 3175 pounds and a Focus weighs 2642 pounds. You must be using politician math.Originally posted by SpiderGearsManComment
