EPA ratings don't mean crap. Friend's 760 is getting about 11mpg combined. As for 30 more hp per liter, easy, cams, TB, exhaust, headers. The vette motors are highly detuned stock. As for YOUR argument about the LS3 not making any power per liter, who cares?? It's making more power at no expense of anything else. I would tend to question why audi (with the exception of the TDIs) or BMW can't make a car that gets 30mpg cruising and still be able to romp everybody on the track.
BTW, reading about the concepts is one thing, experiencing is another. Why do you think I rarely hire college grads straight out of school? cuz they DON'T have experience. have you even taken apart and rebuild a motor or a tranny??? I highly suggest you go out and drive a Z06 vette or a Ford GT. Great cars STREET AND TRACK cars.

Stock LS3 is not even 70hp per liter..I'd to see where you're able to get another 30hp/L just from tuning.. 760li has a combined epa rating of 18mpg..that ain't bad for a V12 pulling around something that weighs that much. And quit the lame arguement of me not being able to afford what im talkin about..makes no sense and has nothing to do with what we're talkin about. 
..All a transmission is, is a torque multiplier, so this arguement of tq down low doesn't hold at all..wide powerband and good gearing are where it's at. |
