Our S650 HP compared to the C8.

[GWink]

The entry level C8 6.2 (!!) liter V8 produces 490 HP. By comparison our little 5.0 nearly matches that at 486 — AND the DH version has more @500! Pretty nice for ” just a pony car”, right?
And yes, I do know how much quicker the C8 is off the line and in the 1/4 mile because the weight of the engine is over the driven wheels….it’s not even close in 0 to 60 or the 1/4 mile……but I’ll bet the 60 to 90 mph times are very comparable!

The C8 has one thing the 5.0 doesn’t have……..low end TORQUE and lots of it.

Yes, at nearly 5,000 rpm for the torque peak on the 5.0, it is WAY up there. I hear that the 5.0 is a monster between there and the 7,500 rpm redline…….Have to do that someday, I guess……lol….

Two very nice cars filling your garage! Adding a Whipple does wonders for the low end torque on the 5.0. With that said the C8 is beast in its own right. I would have no problem parking one in my garage beside my Mustang. I've been a pretty diehard Ford guy for most of my life with the occasional Dodge/Mopar and even Chevy thrown in the mix. On the other hand, I appreciate all American muscle old and new alike.

i am not nearly as knowledgeable about the Corvette compared to any US Ford, but comparing the 5.0L Coyote to the 6.2L LT2 directly does not sound to me like it's terribly fair, and that compounds with how the engines are used in the Mustang and Corvette, on top of how much effort and resources Ford is willing to put into the Mustang compared the GM and their Corvette; this includes their policies and philosophies on the factory tune. the only true similarities is that it's a American cross-plane V8. the Coyote is DOHC with 4 valves per cylinder, where the LT2 is OHV with 2 valves per cylinder. Coyote is 12:1 compression where the LT2 is 11.5:1. the differences continue. the different types of engines lend themselves better to different types of performance. it seems like OHV engines just generally make more torque. even the Super Duty's very conservatively tuned 6.8L little cousin to the 7.3L Godzilla makes 445lb-ft peak torque, and of course the off its rocker 6.7L HO diesel makes 1200lb-ft; both of these engines are also pushrod.

from what i know and have seen and read, it seems like its just easier to make power out of a smaller DOHC V8 than a larger OHV one, with that variable timing carrying a lot of that weight. this might be why the higher trims of the C8 swap out that 6.2L OHV engine for a 5.5L DOHC one. additionally, GM has a variable redline feature on the C8, where there is a soft limiter of 3500 and a hard limiter of 4500RPM until the engine is warmed up, which will allow the full 6500RPM. my guess is that they found some long-term (or at least warranty term) reliability issues without these limits due to how hard they are pushing such an engine.

Numbers don't tell you everything. Yes the DH engine is rated good, but it just needs so much rpm to deliver. The C8s LT2 bascially delivers most of it's torque across most of the rpm band and the low end torque really pushes the car so good.

Here in Germany lots of people use 100 - 200 kmh as a measurement you can pull of on the Autobahn. It's about 62mph to 124mph. The EU Dark Horse runs about 11.0s. I did a 7.9s in my EU C8 Stingray. Both EU models are a tuned down compared to US hp numbers. So even for US rated engines without GPF there is no way a DH would come close.

Imho if you want to compare the dark horse to another car, it's the M2. It's slightly more expansive and slightly faster. But totally in reach if you go for slight modifications

The most exiting engines, if not the fastest, are those that have a flat, or slowly rising torque curve.
That's gives you that feeling of increasing power up to a, hopefully high rev limit.
Some turbos, for example, have lots of low and mid range power, then go flat at a quite low top end.
The 2 litre GT86, was a prime example of a really poor torque curve.
