the cpc 5.2 has been in the gt350 race cars from the get-go. Different cams, but id be shocked if ford isn't using the gt350 heads. my engine builder said that he'd polish them but that there really wasn't a whole lot of flow that he could add to the design.

I like the new wheels, i hate the circular shifter garbage. looks like a rental chrysler 300 console.

i think they missed on not making the hood vent CF to pull the CF theme from the wheels and the spoiler.

net/net Ford's pony cars are punching WAY above their weight in the market. a gt350 makes a rough day at the track for many cars that are 4x the price.

Agreed on the circular shifter. I pray that they don't ever put that in their trucks, or any of their other vehicles for that matter.

No, the issue is that you’re a troll who knows nothing about which she types.

As I said, I spent a week in the backcountry. Everyone else was messing around with gas cans while I did it comfortably with the 36 gal tank. A supercharged V8 would cut my MPG in half and I'd need half a dozen gas cans too.

As for supercharger v turbo, turbos uses free energy. Depending on how big the supercharger is, it takes 100 to 150 hp to run it. That's a lot of extra gas to power something that a turbo does for free. And when I'm putzing along at low speed and out of the turbo, I'm using a small V6 motor. The supercharged V8 drinks like a supercharged V8 no matter how slow it goes.

And I don't think anyone would argue a 5.2L supercharged V8 weights a lot more than a 3.5LTT V6. That makes a big difference in the soft stuff.

If people want to go fast, put the supercharged V8 in the Platinum with its smaller and lighter tires and you'd have a rocket. The Raptor will always be slow on the street because of the 800lbs worth of offroad bits and oversized tires.

Again, it takes a certain amount of joules of energy to lift 6000 lbs up a 500ft high hill. You may be able to generate that amount of energy at most 10 to 20% more efficiently using a turbo 3.5L V6 engine vs a S/C 5.2L V8. There's just not that much wasted energy like you think there is.

The S/C does NOT take 100 to 150 HP to turn. Maybe 65 at full boost, at max RPMs. How often are you in that situation off road? What percentage of the time is your foot really in the gas that deep vs how often are you at 1/4 throttle or less, where'd the V8 would cruise along making no boost. You know it has a bypass valve right? Takes maybe 2 to 3 hp when you have engine vacuum.

I think you are seriously overestimating the MPG hit unless you are just flat out dogging the shit out of it in deep snow or sand or mud, in which case the TT V6 is going to suck as well.

in baja4, I'm getting no more than 8ish MPG when flogging my truck. I love my truck, but damn do I hate the v6 ecoboost sound. i highly doubt the gas mileage is that much worse with the SC v8.

My motor goes and if I can't find a gt500 takeout, I'm swapping in my own CPC 5.2 with an SC with a gt350 block and heads. I'd almost be inclined to swap this trans in too, being that the 8-10 gears on the 10spd are pretty much highway only.

One and ONLY gas mileage thread please

Yeah, I thought 100-150 was a bit on the high side for loss; <-- that’s not the right term but it’s not that big a penalty for a pd blower. Still, you will lose some mpg’s with a s/c and that’s going to be a lot harder on the Jennifer owners than us Jenny owners. You guys have been fretting about mpg’s for 10 years now.

But to your point, the ’17+ Raptors are significantly more efficient --in some conditions, like say... highway cruising--. That efficiency advantage is far less under heavy load, off roading and general f*ck-offery. Sure, we can get 18-20 mpg on the highway. We can also get 8mpg or less off road.

I will love to see more power in the Rap, I just caught video of one in the Dakar, and it had a distinctive (not a v8) sound. We’ve already seen the HO 3.5 make it to the Navi and the fancy schmancy F150, so I’m thinking we’re probably going to see some upgrades on the v6 rather than a wholly new power plant.

Whatever.
This thread was about the net GT500. I can’t wait to see what the ADM on that is going to be.

Ha Ha Ha Ha. There are plenty of reasons to prefer a supercharger, but efficiency is most definitely not one of them.

A supercharger takes about 20% to run, so on a 700hp engine, you're looking at 140hp. Compressing 23,000L of air every minute at 6k RPM requires a TON of work.

And ignoring the supercharger/turbo argument, there is no free lunch. If you want more power, it is going to cost you more fuel. Scaling from 450hp to 700hp at 100% efficiency is a 50% hit to MPG. And if you're not using the full potential of your engine, then what's the point of lugging all that extra capacity around?

Hameedi did a great job optimizing the Raptor for its intended application. I have yet to see anyone complain about the Raptor's power on the trail.

Those that want better 1/4 mile times should be asking for the Lightning's resurrection, not more HP in the Raptor. The Raptor with its oversized wheels and all the heavy offroad bits will always be a horrible choice for pavement sprints. A lightweight, lowered truck with wide street radials would be a far better fit for the Mustang's 700hp engine. (the KO2s cannot even handle the power the Raptor currently has)

It's a cross plane so it shouldn't grenade like the flat plane in the 350

Common man your gonna throw comments out like this at least back it up, i have a 11 Raptor 6.2 with the Rousch and a 17 GT350. I went out to the Larry H miller Sports track (every buyer gets a day out there to learn how to drive these cars) it was amazing the GT350 ran the whole track in 3rd gear (per the instructors) including the straight aways and never once did it hiccup 100 + on the straights. Asked the professional drivers that where teaching the classes if they had any engine problems and it was a fanatic no (they dont work for Ford either) they run the same cars day in and day out all summer spring and fall getting new cars once a year, the old ones sent back to Ford to study and evaluate. The most amazing thing was the ride with a professional driver around the course that you had been driving all day.....i sat there and laughed, i thought i was doing well driving until he showed us how it was done and talking to me like it was no sweat the whole time.....the GT350 is a frickin awesome car from the power plant to the brakes, which never once faded and they got abused!!!!!. The typical driver around the streets will never even touch the capability of these cars. I have yet to put this car in the Drag stip mode (with line lock) but it is on the bucket list.

On R comps and forgelines with a custom dscsport tune on the suspension, I regularly hurt a lot of Viper ACR driver's feelings at my home track. the pcca chapter that rents the track every now and again also doesnt like my car so much anymore either.

drive the hell out of her! the 5.2s run way better when you aren't kind to them.

Turbo isn't free. It's partially free due to heat of expansion (converting some exhaust heat into power to compress intake charge), but the engine's also pumping against more back pressure.

In an engine designed and tuned from the ground up to be turbocharged, the backpressure cost of spinning the turbo is trivial. The 1.5L V6TT Mercedes uses in its F1 car has a staggering 50% thermal efficiency. Compare that to their old NA V8 that was 29% efficient.
