A 2001 mustang gt...and a 2001 mustang gt. one is supercharged, one is turbo charged. same horsepower, same everything but the only difference is the method of FI. Which would win?
And lets assume the same driver did both cars, around a lap or something

I have no idea but WTF is going on in your sig??!!??

I don't know, but somehow I'm offended...

Is this race from a dig or a roll? Even though the HP numbers are equal, what do the tork numbers look like? Is this a twin-screw or centrifical blower?

My first thought is that the S/C will win because of the lack of lag that a turbo will have and it seems that S/C cars tend to make a little flatter torque curve

[energiesource]

im saying a twin screw, lets say a kb 2.1 or 2.6 whatever

and in my sig, its from top gear haha, i love that show. they found the cow on the side of the road and were gunna eat it as their dinner and had no way to get it off the car, so...there it is. v

That sig is funny shit bro.


I would say the Turboed would win, because Turbos give more up top, but it would be close imo. And it would depend on who tuned them, and what Turbo set-up & Supercharger set-up the cars each have.

[Invictus]

s/c will win in the 1/8

turbo will probably pull it out in 1/4


but there are a LOT of technicalities there... nothing touches a twin turbo setup built right.

But if they had the Same Hp The Turbo Wouldn't have "More" up top.

This Question is silly. Way too many options here.

[GTsetGO]

who cares about the HP, what would tq #'s look like. that's the question. I have the same HP as some SC'd cars, but the nitrous is giving me 70 for ft/tq. Looks like i am going to win that ne

[SWEET2KSTANG]

seems the boosted 4.6's do better than the nitrous 4.6's. i running a 125 shot, but cars with boost are getting in the 11's easier. it really depends on how each car takes to the boost and each set up of the cars.

This question is difficult because in order for the turbo to have the same power as a supercharger, it will have to be running on less psi. If they are the same psi, the turbocharged car is going to make more power.

i just say what the fuck does it matter. I am sure there are some more technical questions that can be asked

I'm confused. 8 lbs of boost is 8 lbs of boost. Why would a turbo make more power?

Belt Driven Vs. Exhuast Driven

because a turbo takes less hp from the engine to make its boost

because its more of a end all of those 'supercharger or turbo charger' questions seeing as how they are both at the same amount of horse power, and tq, its really about how the system works. don't get so fuckin pissy

8lbs is not the same for every turbo. A small turbo might take 20 lbs to reach a certain HP while a larger turbo can do it with only 15 lbs. It's about how much air that turbo can move and a larger one will always be more efficient at that. The larger turbo will have slightly more lag though so bigger is not always better.

That first part is a good point. I say from a dig a centri S/C car would pull first but on a roll I would bet on the turbo car if it brake boosted.

As far as torque though, the turbo should build more. Not by a whole lot but bit it still should. Even if the HP #'s are equal the centri is still on limit by the motor (especially on the high end) but the turbo is not. So I would imagine that once boost kicks in the turbo would out torque the Centri.

Well if you are talking "roots" or "screw" style blower to a turbo then you are answering nothing at all.

The roots will win in a 1/8th race or a down low dig all day and the turbo car should edge out in the 1/4 and anything past that (talking about street cars, not full on drag ones).

They both are great power sources but they both are on totally different ends when it comes to the all around perspective of them and how they work.

The only way to answer "which one is better"? Would be to ask yourself what do want out of your car, how will you be using this car, and what will help me attain those goals?

A super charger is belt driven, which means it takes power to make power. Lets say, for example, if you have a car the has 8 lbs of boost (assume there is absolutely no draw on the engine) you might gain 200 hp, but because the super charger runs off the accessory belt in your car you will actually see maybe only 150 hp gain. Now a turbo charger isn't run off your accessory belt, but it does cause a little bit of back pressure. But the loss in power due to back pressure is pretty insignificant compared to the belt driven super charger. So assuming the same 8 lbs of boost (again assuming there is no draw on the engine or back pressure) you will gain 200 hp. But since the turbo cause a small amount of back pressure, you might see an actual gain of 190 hp.

Simply put neither of the two types of FI are perfectly efficient, but the turbo is far more efficient then the super charger because it doesn't take power right off the crankshaft.

Hope that explanation helps, sorry if it's confusing... I just woke up. If you need any further explanation let me know.

As far as the original question goes, it all depends on where these two cars are making peak hp & tq. Which ever car is making hp & tq higher up in rpm band will win... assuming all other factors are the EXACT same. But of course, in the real world, that would never happen. If you put this scenario into the real world, I would say drivers race.
