Good info. Anything on production dates???
we were told "Summer"
weight/price?
Nothing formally mentioned, but it was implied it would be similar to '06 car in both cases.
They spent a lot of time going over the specific changes in the engine
(for all practical purposes an all new engine and controller), and drive train. Tranny is a huge improvement, boy does it shift smooth (they had a car at the tech center we could sat in, sorry we did not drive it). Clutch effort is much lower, and the dif has a much better limited slip mechanism. All this leads to the ability to "stick" to the road and put that HP down W/O wasting it
Engine controller is capable of controlling the variable cam in 1 millisecond loops.... a very powerful controller.... The CNC combustion chambers and ports of the heads are done in a process that rotates the heads in conjunction with the machining. Pretty wild video was shown, hoping to get permission to post it. They said for all practical purposes, if similar CNC heads were done in the after market, it would be a $5000 machining job.
They really pulled out all the stops on the engine, bigger valves (intake valves are hollow to reduce mass) changed the valve angles and even offset the rockers to allow better flow, CNC heads, custom casting to allow CNC'ed throat and valve guides matching to smoother ports, valves are siamesed with keyed seats, dual electronically controlled throttles (now 74 mm) using DC stepper motors, dual mass flow air sensors, two piece plenum, coils for each plug, revised air cleaner that flows more, swing-arm oil pickup with baffled oil pan, high volume/capacity oil pump (needed to "power" the variable cam actuation), Pistons are out of the 6.1 Hemi and more.
Result? 23% more flow on the intake side, and 12% more flow on the exhaust side over the Gen III engine.
The engine sure sounded awesome on the Dyno and when "blipped" over 6000 RPM some saw a flash of 618 HP
