Today's Detroit Free Press auto section, "GM TO REVEAL CORVETTE Z06 AT DETROIT AUTO SHOW." Jan. 13th - 14th. GM expects production in late 2014. "the most track capable Corvette ever, designed to deliver levels of performance through unique power train, chassis and aerodynamic features."
Looking forward to the new Z06 and all that it is going to offer.
Just a guess but I don't think it will have more than 550 hp.
The problem I see with that is the fact that an Edelbrock e-force adds 150hp to an LS2 with stock fuel pump. 200hp with high capacity fuel pump. Hard to believe a factory engineered and configured setup (LT4) won't at least match that sort of increase.
If it is more than 550 hp then great. I can't even count the number of posts over the years where everyone ends up disappointed because they had overly optimistic opinions about what the horsepower figures would be for a new vette model or engine.
I'd rather be pleasantly surprised than disappointed with the final results, but that's just me.
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)
If we get 550hp, I believe we will see a ZR1 really soon. However, if the ZO6 debuts with 600hp+, my bet is we will not see a ZR1 for a very long time...if ever during C7 production.
My guess is we will get a 600hp+ ZO6 and engineers will make tweaks each year moving forward similar to what Nissan has done with the GT-R.
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.
