The 5.5L supposedly aligned to the ZR1 should give nice tech transfer from their race program which has been displacement-limited for many years now, despite the street cars running 6.0/6.2/7.0Ls

The most interesting engine (to me) is the LT6 5.5 liter NA engine - 620 HP is 112 HP/liter, so the red line must be sky high - 5,000 RPM won't get it done, that's for sure. It'll have to be somewhere between 8,000 and 9,000 RPM to put that much power out. They might go with a CPC to improve the torque down low, but that would just make the HP target that much harder to reach. FPC works better up top, and if the forging plant is banging them out anyway...

The big question I have about the C8 - and I'd be in the market for one if the car is properly equipped - is the brakes. The Z51 package comes with 345 mm front rotors, which is where I stopped reading. Even if it only weighs 3300 pounds, it'll still need at least 380's to be a reliable and safe track machine. We'll see.

Brakes are smaller up front more because of weight distribution would be my guess. This is a mid engine car. Bigger brakes in the rear than a typical front engine car. Also a skinnier tire up front at only 245. Too much brake up front would most likely mean a more on/off brake feel and easy lock up.

I did a quick search for brake rotor sizes for McLaren and Ferrari, and their mid-engine cars either have larger front brakes or at most the same size front and rear. None of the more trackable ones have rotors smaller than 380 up front and most are bigger at 394 or more. The thing is that when you lay into the brakes, there's a massive weight shift forward and to maintain stability, the rears have to have less brake effort than the fronts or it'll want to spin. Taken together, the fronts get the hottest.

I understand. I didn’t look at other mid engine brake sizes. I was trying to reason out what they might be doing. They did track test the car. It’s supposed to have an electric brake system so maybe there is something in that factoring into it as well?

Typical Chevy. Get 98% there with a potential world beater and then find a way to screw it with the last 2%

JDee, I believe you're a little low on both figures..I thought the GT was Over $500K and the Vette was near or above $100K...But I get your point!!!!!......I need to get another calculator.....LOL.............

I think Ford will have to rethink the Gt program with this new C8 release. It's going to be hard to justify the GT cost. Honestly I think this Vette might be a game changer for many.
I'm not a Corvette guy but this one is peaking my interest! Hmmmm.
P.S , i'm keeping my Boss!!

Had mine out today!.....It suits me just fine..I may get in serious trouble with more than this...........;):rolleyes::eek::cool:
Exactly, Race Red already attracts enough attention!! ( Not my color of choice but it's what was available and it was a great deal so I went for it.)
