What are the pros and cons of supercharger and turbo? which one would be cheaper and/or better for 4.6L mustang? S197

I think this can help.

But in my opinion if you want all out performance go for turbo, because it doesn't require hp from the engine to run like superchargers do.
But the Turbo is more expensive.

Thank you, it was a great piece of information, but which one is more reliable? which won't kill the engine that easy and have less problems?

If you want something reliable that won't blow up the engine and just works, get the Ford Racing/Whipple kit. The only thing I might add to that is a heavy duty belt tensioner (to keep it from going through belts) and an electric water pump (so that when it does throw a belt, you can continue driving without overheating the engine).

I'm confused, isn't that a supercharger? that gets around 500hp from stock?

danzcool

Yes, it is a supercharger, that gets about the max power out of a stock 4.6L 3-valve engine without blowing it up. The generally accepted limits of the 3-valve, 4.6L stock motor are 450-500 rear wheel horsepower. The Whipple supercharger makes 550 crank horsepower which is about 467 rear wheel horsepower on a manual transmission car.

Supercharger all day every day for those reasons you want. Mine drives the same as it did stock with the blower setup just way more fun. I have nearly 500 passes at the drags with it too, so there is your reliability. I have around 430 rwhp.

the DOB manifold and gt500 supercharger is a good combo.

properly-sized turbos give you more low-end torque because their boost output is based on engine load and not engine speed. problem is it can be a lot harder to develop an ECU calibration because turbos are non-linear. modern gas turbo direct-injection (GTDI) engines are out-torquing diesels of similar displacement.

the other downside to turbos is that "properly sizing" them is a trade-off. if you want good low-end pull, you want small turbos which spool up really fast. but they're going to run out of breath before the engine gets up in speed. if you want big HP numbers, you'll need bigger turbos which will lag and your low end will suffer.

I am of the opinion that boost is boost. Pros and cons to each method. I chose Procharger for 3 reasons: They are only 15 min from my house. // I know several people that work there./// I became a dealer and got it at dealer cost.//
I do love the constant sound they make. Certainly gets attention, even being 8 years old.
Turbos are a little bit harder to tune, and more complex to plumb. The second part is what makes them more expensive to buy and harder to install.
Any major brands have been proven to work well, and for a long time. Durability and quality is not an issue as long as YOU the OPERATOR don't do something stupid. I installed my blower at 3300mi and have been smiling ever since.
