Subercharger vs. Turbocharger

[f5fstop]

Gas engine...supercharger. Give you instant power, turbo take some RPMs to wind up, and you don't want to be revving the engine on boulders to get some power.
Diesels work better with turbos since they already have tons of low-end torque and need a boost at higher RPMS.
Drive a Dmax turbo, the thing pulls a house, and around 2700 rpms, when the turbo really hits the boost, it jumps.
Just my opinion.

Supercarger on a gas engine does the same as a turbocharger on a deisel engine. It runs all the time forcing more air into the intake.

A Turbo on a gas engine just kicks in when you romp on the gas giving a boost when excelerating.

If I were to pick one I'd go for the Supercharger. Increase power across the power band.
If you decide to drop a deisel engine in your H3, don't waste your time on a deisel engine without a turbo.

Turbo relies on exhaust gases to increase boost, supercharger relies on a belt. Exhaust gas build up does not happen immediately to spin the turbine enough to create a large amount of boost. I have driven a turbo DMAX and max boost is not until around 2700 rpm, off the line there is almost NO boost.
Possibly some other diesel engine turbos work differently, as I know some gas engine turbos create boost quicker.

Yeah Man,
Supercharging....much more better...and..you can smoke your tires real good from a dead stop. Pic of my 86 Vette with a Carroll Supercharger and
Gasious Water Injection system. A fun Tire shreader...
