Our S650 HP compared to the C8.

[Cz_Ziemniak]

You can make a similar cubic inch engine, one with more stroke and one with more bore and it will make the same power.

You can, but they would make the power very differently, no?

The engine with the longer stroke would make the power at a lower RPM with a higher peak torque figure, vs the shorter stroke making the power at a higher rpm and lower peak torque figure - assuming everything else is exactly the same

Again, I've never seen anyone say that rod angle doesn't matter, rather the opposite.

Nope. You're using the same amount of air each stroke, doesn't matter if you use bore or stroke to get it.

Again, I've never seen anyone say that rod angle doesn't matter, rather the opposite.

You're talking rod angle/rod ratio now. That's not bore vs stroke. You can use different length rods in the same stroke engine. Again doesn't really matter much

And again, another common myth/misconception.

Ahhhh, okay, I see. Makes sense

When you are talking about rod angle, are you referring to the width/circumference of the crankshaft? Makes sense to me that a wider crank would yield more force on it each stroke, than if the rods are connected more closely to the center.

the angle of the rod inside the engine

shorter rods have more angle

The Camaro no longer being manufactured makes it not really competition anymore.

I'd argue that the Camaro SS is as good if not slightly better performance car than the s650 GT/Dark Horse

@Germansheperd ..... thank you for the side-by-side picture. It 100% confirms why I bought the Mustang and money had nothing to do with it. I want a real muscle car, aka a pony car not something that looks like a misplaced child's transformer toy. I never look at late model vettes that I see while driving around but 90% of the 'vette drivers look at my 2024 GT vapor blue convertible with space gray sets and up-graded rims. Ha Ha....Just sayin'. BTW this is a Mustang forum not a kid's toy car forum ..... but I will wave back at vette owners who wave to me. I mean there should be a "little" respect for vette owners. But - just a little!

@kagemusha2662 ..... and according to several side-by-side comparisons you'd be wrong on a number of aspects. BTW - IMO the Camaro dash is the effin' ugliest piece of crud I've ever seen on a vehicle ..... zero ascetics ...... just weird and ugly. BTW ll the trunk on a Camaro convertible is about 70% the size of the Mustang and the roof line is so low it looks frickin' stupid. Nice try - keep the Stang.

So I did some further research. Looks like a big part of why 2 valve's make more low end torque vs 4 valve per cylinder DOHC heads is due to air velocity at slower engine speeds, which makes a lot of sense now.

2 valves per cyl allow for higher air velocities at low RPM, but ofc that comes with flow restrictions at higher rpm's.

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!

I was a Mopar guy for 25 years and lastly owned a 2021 Challenger R/T Plus and had 4 SRT's over that time. The mystery was always Mopar's 6.4 producing 485HP and the 5.7 producing only 375HP and the Mustang with a 5.0 producing 486HP. LOVE MY MUSTANG!!!

It is if you're comparing '24 models.

So maybe it would be competition if GM had decided to compete, but they didn't. There is no GM pony car competition for the S650.

Production ended December 2023 (2024 model). Do they still have new 2024 Camaros on dealer lots? I haven't looked.

 

[Junkyard Dog]

In February there were 37 available nationwide, including 1 in Hawaii. This is June almost July.

why don't we toss a Tesla S Plaid in the mix and see what car smokes what car

Yeah, my last electric car was capable of a scaled up 400 kmh.
The problem was, I couldn't sit in it, it ran in a slot, and I didn't have a licence, I was 13.
I don't consider EV's to be cars, fast fridges maybe.
