Not on a road course. Which is why figuring out your desired use matters.

Plus Car & Driver did a test of a dealer that was selling Mustangs plus aftermarket super charger kits. And despite a claimed 700hp, they were only slightly faster than a standard GT and slower than a GT350.

Couple of other issues, if you just want 650-750 hp. A supercharger is cheaper and easier than turbos.

If you just want to brag that you have a lot of horsepower, just lie. Like most internet power claims.
I would bet they were actually a lot faster once traction limitations was taken out of the equation. Slap a set of slicks on the regular GT and the boosted GT and look at the difference Or just line em up from a roll.

Not gonna run on to many people that can say they owned one of those.
I had a college friend that had one. Fun little car. I really liked it at the time.

cannot denyā€¦but then I have a list of cars like that šŸ˜‚



cannot deny this eitherā€¦but once you wring them out above 4,000 it a whole nother animal šŸ˜‰
I remember thinking the Charger compared favorably to the 1976 Cutlass with the gutless 350 V8 I was driving back then.

Faster for one hit. If you're a dragstrip guy - perfect. Many supercharger setups can't continue to deliver power after a couple laps on a road course. The older GT500s, for example are dog slow. By the time the tires are warm enough to push it, the power is gone. However, it's certainly possible to build a setup that continues to make power, like the new GT500 or Dodge's assorted Hellcats. You just need a heck of a lot more cooling than typically is included for mild use like dragstrip or street driving.

Centrifugal superchargers don't have the heat soak problems PD blowers do, and can blast away on a road course no problem. They'll still get hot if you stay in boost for long periods of time, but you're not constantly in boost on a track.

More power always equals more heat. On track you are almost always either on the gas or on the brakes. AFAIK there's no perfect solution. Otherwise everyone would be using that one perfect solution. There's a reason the OEMs don't often use centrifugal superchargers.

What is the reason?

No idea, you tell me. My assumption would be thrown belts or poor durability/longevity. If centrifugal superchargers were the best power adder lots of cars would have them.

I didn't make the claim there is a reason, you tell me. Based on how they work compared to PDs they should be easier on everything as far as belts, the engine, and so on. Not sure on longevity, would think they would be similar to turbos (except they have way less heat going through them). In years past I can see why PDs ruled as far as torque curves and transmission options, but I think with the A10 this changes things. By the way they are on lots of cars, there is a rather large market for them and has been for a rather long time. OEM doesn't design for the best, they design for the bean counter.

There's no need to prove anything further than just looking and noting that the OEMs don't use them. If they cost more than the other options, that's a great reason not to use them and to go with something less expensive. Maybe the aftermarket ones don't cost that much, but if you make a high quality version that would satisfy an OEM, they then become too costly. Who knows? There is a good reason for it.

I ran D/GS on the strip with a 55 Chevy running a small block with a centrifugal supercharger. They typically don't develop much boost until you are at higher rpms. You can tweak pulley sizes to get them to boost sooner, but that tends to cause a variety of issues they are not designed to handle.

I agree this is the internet, one can make claims and not have to prove anything. There is a reason, I agree with that as well. It most likely is what makes more money, might have nothing to do with most effective form of power adder. The thread is asking about putting twins on a GT, well there is no TT on coyotes from the factory so the OP should not consider them because well there is a reason they don't come that way; along with any BMR stuff, slicks, or much of the other go fast stuff. I guess the answer is the GT350.

OEMs do use a lot of turbos, though. Most don't use them on V8s, but that's just because they don't want to make that much power.

Not on a coyote.
