The Plan for the New Corvette

Seen the New Z-06 released the other day. What a remarkable automobile 670HP but with a new flat plane engine. That worries me a little. Just remember if the engine spins faster up to 8600. it will wear out faster. So an announcement a supercharger is made for the 6.2 engine. It will produce 705 HP. Basically the same set up in my Dale Earnhardt Camaro it makes 704HP. Now the rest of the story. I qualify for a discount thru GM to buy a new 2022. Which I hope GM sets up by Spring to mid summer. Getting close

I have read flat plane engine but dont know what it means.First thing comes to mind is a boxer engine.
I read about the flat plane and wondered about its life with the higher rpms. I know Lingenfelter is a great company with a great rep but wouldn't adding a supercharger to an engine like the 6.2 that wasn't designed for it also shorten its life as well? Of course maintenance, driving style, mileage will all have an effect on the engine but will the parts stand up to the stress from the added boost/horsepower? I am not being critical of your choice, just curious about how the engine will hold up in the long run compared to a stock engine. Bob
Do it!
buddyb, it has to do with the relative position of the crankshaft throws. Unlike a typical V-8 engine the throws are in a flat plane (hence the name). That is, they are either at 3 o'clock or 6 o'clock.
I expect mine to be here in April.
GM has taken the same 6.2 that was 426 HP in 2010 and most likely done head work for flow or cam work to get the Corvette to 495 HP. The 2010 mods had larger injectorxs, Kooks headers, the supercharger, lIngenfelter fuel system to feed it. Basically it is 65% over base horse. That is a lot. It has approx 11 pounds of boost. However the 6.2 engines will take at least 1000 hp on the lower ends and stay together. So the 495 to 705 is only a 42% increase. They are stating much more to come in their stage 2 packages or more. The newer engines are so much stronger on the lower ends than the old 350 5.7 engines it is unreal. That Dale Jr. camaro I own is 525 HP it has Weisco race pistons, Kook headers, Total worked heads, cam. I recall the old 69 nova I had that was 350 / 350 Hp and it flew. The 525 is remarkable. Durability , that depends on how the car is driven. If the HP is there the right foot knows it.
Pictures when you get it please.
A typical V8 has connecting rods on individual journals spaced 90 degrees apart rotationally. A flat plane V8 like this is built like a monster 4 cylinder engine with crank journals 180 degrees apart, but this one has connecting rods sharing journals. It eliminates the weights needed for secondary vibrations, which means it vibrates like a bunny on crack. They made the engine massively over square with a 104mm bore and 80mm stroke to keep piston speeds down, and use exotic rods and pistons to keep it together.
Did you opt for the Kevlar glove box upgrade?
The NO Taurus option. 😃
Long life is not predicted for a 700-hp car. Most of them will be shattered into small chunks on concrete bridge abutments within a year or two.
Get it and drive the hell out of it.
Chevrolet engineers thought hard about balancing the engine to reduce the secondary vibrations the "flat plane" tech will produce. They decided against it, so it reportedly revs like a contemporary sport bike, BLIP BLIP BLIP. Instead they focused on isolating parts so they don't vibrate into dust.
Boy this thing is going to sound nice.

I know better than to buy anything with a lot of power under the hood. My old Camaro is "just" a 350 and I find myself going way faster than I mean to every time I drive it.
