I don't really find that a direct comparo of supercharger vs. turbo is all that fair. But is a good comparison for decided what you want/need.
Yes a turbo in
most cases will get you more grunt, and more tune-able and adjustable grunt at that. So for power this is probably the best way. Your sweet spot will be mid range to high rpm, depending on the turbo and manifolds chosen.
The supercharger although doing the same job, cramming more air into the motor, goes about the idea quite a bit differently.
After doing my car I'm leaning towards turbo as the best option. However, the bottom end and mid range can't be beat and the simplicity and cheapness is definitely a bonus when using 'chargers. A heavily worked supercharged beast is going to make alot of power and a lot of torque (gearboxes...look out!), as long as the 'charger size and type is chosen wisely.
The main problem with 'chargers is efficiency. They are just not good at making high boost - they, generally speaking, make a lot of heat. But if your keeping the boost to a sensible road-car level, I see no problem with going eitherway. The car will be fun and fast anyways.
It's up to you completely, go to
www.turbominis.co.uk and have a browse, however i must say they are very biased on there, even though many users have superchargerd cars they will ALWAYS suggest turbo as the best option.
