Looking forward to seeing this car. Unfortunately I think it is going to be priced too high for me to become a 7th Gen Z06 customer. My current Z06 will most likely have to hold me over, although that's not all that bad. I love this 08 Z06.

Supercharges = heat = reduced timing on road courses! What are they going to do about that?

While they may not make it a forged motor compared to the LS9 I cannot imagine LT4 would make less than a ZL1 LS8 motor that is still considerably more than your 550 speculation.
Having to overcome an already considerable problem with the weight of the C7, without a drastic and expensive diet, the C7Z will have to make 700 HP just to keep the power to weight numbers on par with the C6 ZR1.
Something the C7Z model MUST keep up with if they hope to sell it to ZR1 owners.
(The ZR1 top gun model was considerably heftier than the lightweight ZO6 with 133 less HP)

With GM claiming it to be "the most track capable Corvette ever, designed to deliver levels of performance through unique power train, chassis and aerodynamic features" I suspect that if it is supercharged it will have a really efficient intercooler system. Maybe an air-to-water interooler? Would definitely add complexity and weight, though.

IMO... 405 --> 505 --> somewhere between 605 and 640 only because of the ZR1. I don't think it will out power the ZR1 by all that much if at all.
Doubt it will be below 600.. That would be disappointing.

F1 is going to small displacement/forced induction as part of the push to make this form of motorsports "more relevant" to the push for higher efficiency. Whether or not lap times will be quicker solely because of the new engine spec is yet to be seen. On-going tire development and aero development will kinda make it hard to determine just how much the new engine formula, by itself, contributes to the lap times.

The point is, there are plenty of FI racing engines in several different series, so my point is that one can not simply dismiss the idea of an FI engine not being race proven.

Agree. Like I said in the other thread, I believe the "official" number will be 605HP which sequentially makes the most sense. I also don't think GM wants to irk the current ZR1 owners with a car that drastically hurts their car's value....but I could be wrong if the C7 Z06 turns out to be the top of the C7 line.

Well, they are going BACK to FI, and from everything I've read there isn't anyone that doesn't think times will not be reduced.

But the reason to move to the smaller displacement/turbo formula was engine supplier driven (i.e.: all the manufacturers who put all the bucks into the engine programs, and see F1 as both a marketing and technical exercise), and for perceived fuel efficiency reasons.
In any event, changing the formula should be fun viewing for the first half of the season while all the engine suppliers figure out how far they can go with their designs before blowing up engines. We'll start the fun on January 28th.
Back to LT4 relevancy . . . whether any of us like it or not, smaller displacement forced induction is the way that the industry is going to move to, with the higher efficiency legislation. But innovation will never end, and superior packaging, better cooling, better throttle response (for turbos) will continue to evolve. I love my 7.0 liter/427 cu in LS7 in my C6 Z06, but I'm also looking forward to trying the LT4.

Odd we have no real news / pics at this point?
Seems odd to me that 3 weeks away from reveal we really don't know much and other than the front lower fender / wheel pic, no spy shots, etc.

it would seem that all that is required is an enhanced heat dissipation system, to more efficiently remove the ambient heat generated from the obviously higher operating temps. i say "all", and realize that this may not be so easy, given other factors e.g., space constraints [i use the word du jour "constraints" intentionally here]. and, clearly if they had one, it would already be in use. but, time and innovation march on.
Seems like the word du jour, is du jour.

Agreed. It seems we got that teaser lower fender and LT4 engine pics back at the very beginning of December, and nothing at all since. Strange...

Your reasoning makes sense & may turn out to be 100% correct. My thought was that the (C6/Z06/ZR1) formula worked for GM last time & that they would do the same again with the C7 to keep interest alive throughout the entire production run.
Since I guessed 550 hp I'm going to stick with this figure to avoid accusations of being irresolute. Like I said above, if the horsepower ends up being quite a bit more (i.e. 600+) then I'll be pleasantly surprised instead of disappointed. It certainly wouldn't be the first time I was wrong about something.
