Once again the only correct answer is “Yes”!

If you want it to feel NA like you have a bigger displacement motor with more immediate response where you still have to rev it out then get a supercharger. A supercharger will also be more forgiving on the internals because there is less low end torque. There
If you want more drama, sound, efficiency, tuning control and low end torque then get a turbo.

With a Positive displacement? NO. A PD blower will give that TQ from just about idle. Also low end tq can be minimized or enhanced based on size of turbo (pulley for SC) and tuning (Wastegate for Turbo). |

I voted turbo because I feel poll thread should be even.

Supra dyno showing full torque at 2k Different torque curves, showing PD supercharger still building torque Yes, a larger and slower spooling turbo will have less low end torque than a smaller turbo, and yes, a tuner could do boost by rpm to avoid low end torque and to ramp up boost. Someone could definitely design their torque profile to match a supercharger's torque profile. Most don't do that.

Turbo if you know what you’re doing and/or want the most whp to crank hp ratio.
Supercharger if you don’t known what you’re doing and/or don’t care about whp to crank hp ratio. |

Also, do a turbo if you want to do boost-by-gear, boost-by-rpm, multiple boost maps, etc. It is also easier to run a turbo with FlexFuel/E85, especially when E85 is not always available; I would need to swap pulleys if I couldn't get E85 or drive around without going into boost or something, but a turbocharged car could just do boost-by-fuel by either limiting boost or just running a completely separate map. Finally, you can always swap to a different sized turbo or vary exhaust and compressor sizes if you are not happy with your turbo profile. You can swap superchargers too, but it isn't always as easy or an option. The JRSC has the C30 and C38, but the Edelbrock kit doesn't offer a different sized blower. It is typically much easier to option a turbocharger of your desire during an initial purchase, and it is easier to make a swap later--typically.

Seems like there is just overall less to go wrong with a SC vs turbo and they have greater consistency to throttle inputs as it is directly driven off the crank. |

Another benefit of a turbo is more power at varying altitudes. A supercharger at altitude will achieve less psi at a given pulley size than at sea level, but the turbo will just suffer from more lag, but still hit full boost.
