You do know those cars are artificially balanced by IMSA so they have roughly equivalent performance, right?

Doubt it! If you like science when I get back home Sunday will show how reducing exposed cylinder wall area cut engine temp. Reference is on book shelf!

Not only is it more powerful than the Ford GT, but gets better fuel economy too. So which engine is really more advanced?
The FordGT is geared to beat the C7R, which it is unfortunately doing.

But don’t worry with the Blackwing or Blackfoot or whatever name modern engine they are building in BG the C8R will beat it’s butt!

LOL, neither of these race car versions are production cars. Try a less lame argument.

The factory stock C7 ZR1 turned a faster lap time at VIR Raceway than the megabuck Ford GT, despite being driven by an engineer (not a professional race car driver), and additionally handicapped with a front-engine chassis layout.

Stick that in your pipe and smoke it.

I really like "Skate, Piranha or Barracuda". Moves it away from the Indian names so Lizzy will not be offended plus moves into the more historic killer fish based Corvette nicknames.

I think what's fooling people into thinking they hear a V6 or possibly a flat plane crank V8 is the exhaust system. On a cross plane crank V8, the firing order goes L-R-L-L-R-L-R-R. This causes some interference in the exhaust system, which costs some horsepower and is what gives a big cammed V8 that potato-potato-potato sound. Around the track, you get an engine that sounds like this:


An X-pipe is a band-aid fix for this. You still have interference in the exhaust pulses. However, in a mid-engined car, you have another option: The "bundle of snakes" exhaust:



It evens out the exhaust pulses through the collectors, improving flow and giving a significant horsepower boost at high rpm. However, it makes the engine sound a little like a V6.


It sounds like this:


Both cars have old skool cross plane crank V8's. The difference is in how they route the exhaust.

I would hardly call it "old skool". The upcoming Ford Shelby GT500 went back to a cross plane crank.

Pretty sneaky! Ya just can't trust those darned politicians!
As a Californian with the highest gas taxes in the nation, don't fall for this. We have the worst roads in the nation, and the highest gas taxes. They keep increasing the gas taxes and car taxes saying it's for the roads, and the roads are just as bad as ever. We may not be driving Corvettes much longer here, because we'll need the money to buy a motorhome to live in.

You guys seem to have a Liberal disaster that is getting worse by the day. I honestly can't imagine living in a "Sanctuary City".

Yeah but the fastest car at VIR Lightning Laps was the turbo 6 cylinder 3.8L 700bhp Porsche which somehow got left out. That's a car I think you don't like based on some posts.
