Guesses at actual certified Corvette Stingray HP/TQ numbers?

So Chevy's estimate is 450hp / 450lb-ft

...and we know that when Chevy says "estimated power is..." they really mean "it has way more than...."

My guess is 460hp / 460lb-ft.

I'm going to guess it's going to be a lot closer to the current Z06, just like the C6 base car was close to the C5 Z06. I'm going to guess 480/480.

I think your pretty close I would guess the same.

Your taking RWHP right? Because a C6 Z06 has 505 at the crank

I'd say 470hp/470tq at the crank. That seems like pretty decent bump while leaving enough room for a Z06 to add another 50hp or so down the line without taking a major MPG hit.

As long as it is over 430, I'm good, er the wife's good. Well at least until Magnuson gets their SC kit out for it. I'm not sure how this DI thing is going to work with a supercharger.

No I'm talking crank hp/tq. 480/480 sounds good to me, it would still allow the C6 Z06 to be the better performer between the two with lighter weight, more power, and larger contact patch, and it would give the newest generation Z(whatever) vettes lots of room to grow in the power department.

My honest guess, for the big dog vettes when they do come out, is going to be 600+hp, plus much bigger tires than what they offer on the base car (255/285).

There is some logic to my madness. First, you don't add DI, higher CR and VVT to an engine and only see 20 HP. On top of that the C5 Z06 was 405 HP and the C6 LT was 430 HP. So, doesn't seem like GM has a problem with the base model making more than the prior generation performance/track model. Would be nice, wouldn't it?

I like your logic. I do get your drift and certainly hope your right
