Seems like the Ford 7.0 rumors are gaining ground and that engine could wind up in the Raptor. If its true, I don't see how Ford can build a 7.0 V8 but GM can't.

If it's true....possible benefits of a DOHC setup.

If it's true....it would also be upsetting for just the last statement you said.

I really wanted a 427. The GS/Z07 with a 427 would be perfect! I’d have paid another $10K for it.

If they build a 7.0L V8 for Raptor - I will be a buyer for that for sure! Here is a photo of my 2014 with 6.2L that I sold last year and really miss it. Just can't get interested in the new Ecoboost version!

2020 GT500 with a supercharged 5.2?

Happy Thanksgiving to The House.

As always many thanks to those home and abroad away from their family an friends protecting us and keeping us safe and protecting our freedom.

[Supercup]

+1 - Happy Thanksgiving to all!

Tesla claims the sleek, targa-top two-door can accelerate from 0-60 mph in 1.9 seconds, go 0-100 mph in 4.2 second, and complete the quarter mile in 8.9 seconds, numbers that would make it the quickest production car in the world."

But, and it is a big BUT, the heat that iss produced running a lap on a road course is so intense, the Tesla cannot complete a lap at the Ring, not a single lap at speed. So much for supercar performance.

That's the difference between a performance car maker...and an appliance maker.

The Ring? Hell, the Model S can't complete a full hot lap at VIR. Car & Driver brought one out last year for the Lightning Lap and it lasted all of 40 seconds before it cut power.

Wouldn't surprise me if the new Roadster can't actually achieve its claimed top speed. It should take at least 30 seconds, probably 45 or more, of constant acceleration for it to hit 250 mph. As tough as a road course is, there are still periods of partial or no throttle to help keep things cooler. And the Model S doesn't have as much juice as the new Roadster will have. Maybe they'll have a kickass thermal management system in place, but I doubt it.

BUT! In order to maximize efficiency, the car will regeneratively brake to recapture power during those no/part throttle moments...which will generate more heat.

It really isn't that hard to cool down an electric motor... The ICE generates far more heat, and manufacturers have got that down to a science.

My guess is they opted not to do it, because that would decrease the car's aerodynamic properties, and ultimately decrease range.

. You're right, electric motors are (relatively) easy to cool. Give the casing some fins for extra surface area, some ventilation holes along with fan, and they're normally good to go indefinitely. And even when an electric motor gets a little hot, it still works fairly well.

Batteries, on the other hand, are not so easy to keep cool. For an electric car, just as much power flows through them (give or take) as the motors so there is lots of heat generated. And Li-ion batteries don't react very well to heat. Get them warm and they degrade. Get them hot, and they can explode.

Sure, the heat will be spread out in a battery but its a lot easier to cool a small hot thing than a big warm thing. Its not that its impossible to manage, but they'll actually have to put the time, money, and effort into getting it right. And, well, its Tesla. They're not exactly known for putting resources into getting things right ahead of time.

Was about to do the same thing.
