700 horsepower

[Coyotes55086]

So this is something I need to understand lol . I've never driven in a car with this much power. How does it work... will any car with say 700hp always be faster than a car with 400hp ? is it possible for a lesser horsepower car to feel and be more powerful? A stock s550 vs a supercharged s550

will a supercharged s550 basically be faster than any stock car on the road beside you?

As a very simple starting point, power to weight ratio determines how fast a car can accelerate. This is assuming everyone is on tires with equivalent grip, and not worrying too much about the details of the drivetrain.

Probably the easiest way to think about power to weight ratio is the horsepower for every thousand pounds of car.

A supercharged s550 might make say 650hp at the rear wheels (750ish at the crank), or more or less than that depending on the exact model year, supercharger, and fuel. But 650 rear wheel is easy to do with a turn key kit. Compared to various stock cars, that will out-accelerate nearly all of them from a roll. From a dig, the rest of the driveline matters more. But it's about the same power to weight ratio as a Lamborghini Aventador, Porsche 911 Turbo S or a Ferrari 812. A few quasi-common cars like a Ferrari F8 as well as lots of rarer exotics will be quicker. Of course the S550 does not have aerodynamics really suited to a high top speed without mods. Stock, it's electronically limited to 155 mph and starts mis-behaving if you remove the limiter and go much above that without making some changes.

Stock Mazda Miata will beat 700hp Mustang at a typical autocross course.

Stock Mustang will beat Miata at a drug strrip.

from a stop a supercharged mustang is just as quick as the stock ? how different is the supercharger and where does it really shine ? im guessing highway speeds?

u talking about handling or speed ?

Of course autocross is about the narrowness of the course and that's it, which is what makes it the most retarded form of racing that doesn't involve camels

? Pretty sure the pp2 beat the mx5 at laguna seca, and other places.

1:40 best time for 2019 mazda and 1:38 for the 2018 mustang.

For a given level of traction that your tires can achieve (measured in "g"s of acceleration for simplicity) there's only so much horsepower that can be used. That amount is basically proportional to the speed. What this means is that at speeds below about 50mph, factors other than engine power determine acceleration. Things like tire compound and structure, tire pressure, AWD vs RWD, track prep (if on a drag strip), transmission shift time for the 1st to 2nd gear shift etc. Mustangs are not exceptional in any of these attributes off the showroom floor, and as a result you can expect certain cars to beat them to 60mph by a couple of 10ths of seconds. Of course if you want to put on drag radials, use a transmission that can get to 60 without a shift etc. you can do very, very well at 0-60 but by default the mustang isn't special and a supercharger won't help but for the very last bit of it.

As soon as you get to a high enough speed that your tires can hook up at WOT, the supercharger is helping.

Yeah I have. And I was successful. And it's completely retarded. Any layout that a kart can run faster than a car is a stupid thing to run a car on.

The appeal of autocross is that it's cheap and lets you learn how to really drive your car at the limit with minimal risk. If you get caught up in pure times and being competitive, that's when I tend to agree with you. Especially since most course designs favor low HP, high grip vehicles with short wheel bases. Especially the slalom section, which most course designers always over use for some reason. I think they're anti fun personally.

It will all come down to “how” you use the said 650-700 whp. On street tires it will take 80-90 mph before it will fully hook up on average. Sure a 95 degree day will help hook. My car on E85 n/a with drag shifts is a bear until 55-60 mph on PS4’s. If running full time DR or slick (throwing handling out the door) is in your plan then that will help hook. Tradeoffs always with more power...

No. I have beat a 740RWHP Supercharged 6 speed 2016 Mustang in my Tune only A10 GT. Too many variables.

Acceleration is power/weight, up to higher speeds, where its power/air resistance. A blown Miata can keep up on power/weight with a muscle car, but it will still have a lower top speed. The air resistance just overwhelms the smaller engine. A larger muscle car can power through the air resistance with horsepower.

The final top speed is entirely horsepower vs air resistance, weight isn't a factor at all.

That's why the Mustang is a 'GT' - Grand Touring - With the horsepower (and weight) it excels at cruising at higher speeds.

Handling generally benefits lower car weight (all things being equal), so lighter cars can do pretty well, but it takes driving skill to get a car to handle. Tires compounds work and grip better when scaled down on lighter cars. Horsepower doesn't help in a corner, and the porky weight is a liability.
