It's a beautiful engine.
The mid-rear engine exotics (including the vette) all start out lookfing similar because they are form following function. The designers made it look like a Corvette. Maybe you like the looks of the Bugatti or Ferrari or Ford GT or others better, and I can respect that.
I've never been a fan of the folded paper look, but that's just me.
The Vette, for the price, is a value compared to the other. You could buy it and have Dave Kindig or your favorite customizer make it unique and have it perfect to your view.
Congratulations for uncritically falling for GM’s dishonesty. They certainly have a lot to be proud of with this incredible new powerplant, and I don’t doubt that they’ll be successful in minimizing its maintenance needs, but of course exotics don’t have to be taken apart every 10,000 mi. (Heck, I have a Ferrari that’s almost as old as I am, and even it doesn’t have any service intervals that short, outside of oil changes.)
LT6: Proving that you can take the embarrassing lack of sophistication out of the GM V8, but you still can’t take the embarrassing dishonesty out of the GM PR.
I'm sure the "every 10k miles rebuild" is a funny exaggeration but there is in fact short ridiculously expensive engine out servicing for some exotics. It's probably closer to 30 thousand miles for some of the engine out maintenance. Valve train adjustments, overly complicated oil changes and other things if you choose to actually drive the car. You get the point they were making.
Everyone is just trying to enjoy this American engineering marvel. I'll never understand why people comment just to spread negativity. I think most of us reading this article have a passion for all kinds of great automobiles. Let's all enjoy this.
For every piston moving towards TDC there's another moving towards BDC, so it's a wash. But 80 kPa is an impressive amount of crankcase vacuum, almost 12 psi. A side benefit is that you'll never see oil spraying out of an oil pan gasket leak, but instead air will rush in.
Ah, I missed that part. Interesting, so RokemRonnie's comment has me wondering. With a 104.3 mm bore and 80 kPa vacuum that translates to a little over 150 lb of downward force on each piston as it's moving upwards. Sounds like a defecit, except somewhere else on the crankshaft a piston is moving downwards and benefitting from the vacuum. So maybe it's still a wash, but in the force calculation not the pressure calculation.
No more than any positive pressure would make a piston work against the intake and power strokes.
Each cycle would experience some such resistance half the time and *assistance* the other half. The net should zero change.
