turbo charger vs. super charger

[bluevette74]

We all know that the turbo runs off the exhaust, and the super runs off the crank. Which would you prefer on your car, and which would you perfer on a carbed 350!

[YogsVR4]

Turbo charger all the way.

I dont know about on that 350. I would still think the turbo would be less intrusive on the engine.

Turbo will give you more gain than Supercharger.

[YogsVR4]

I'd augment that by saying the turbo has the ability to give you more gain, but it does not garentee it.

[F20C]

YogsVR4 I meant to say potential.

I always have preferred a Turbo over the Super. Besides you get better gas mileage than a Super with a Turbo, plus you have the potential to get more gain.

I like turbos.

[RazorGTR]

You would better off supercharging it, being carb'ed. If you were running a fully adjustable ECU with injectors I would say turbo.

In theory, turbocharged cars should make better gas mileage than supercharged cars. In practice, this often is not the case. While the turbocharger is so efficient on paper, it rarely in execution demonstrates that potential of exhaust gas "recycling" via exhaust-driven turbine.

Agreed 100%. For a carbureted application, a supercharger system is the way to go.

I guess I should have said potential for that as well. With my turbo cars I get great gas mileage unless my foot gets a little too heavy. I can usually get 330 to 340 miles to a tank on a 12 gallon tank. But you are right not every turbo car gets better gas mileage.

Supercharger. Much more linear power curve, simpler, and cheaper.

[hakka]

yeah, I would go with the supercharger, for all of the reasons said before.

It really depends on the application. Roots and Centrifigul perform differently.

Roots give more linear powerband.
Centrifigul gives very little gain down load but a whole lot gain up top.

Turbo can also give linear powerband as well. Twin Sequential Small Turbo much like S4's. Very little Turbo lag and flat powerband. Tradeoff here is less potential for more gains.

A single big Garret Turbo with massive gains but peaky powerband. Not very ideal for street use.

Heheh like mine! There is nothing but flatness until around 4,500 rpm. Then all hell breaks loose
