I don't know anybody with a Supercharger on an FC, but I know a LOT of guys with SC & Turbo Miatas. Both setups work very well, but in an Autocross or Road course application the SC seams to have a slight edge because of the instant boost. If I were to drag race I would definately go Turbo only.

I wouldn't be afraid to run 9lbs boost on an NA engine but I wouldn't want to try much more, although starting out with high compression it would probably be about the same as running 12 in a Turbo engine.

1 thing to watch (especially if you have a higher revvin S5) is the max RPM of the SC unit and the ratio of the drive running it. If your car revs to 8800 and the SC is only good for 8000 - make sure you gear the drive down so you don't over-rev the SC.

So what would happen to a NA tranny if you added boost to it?

 

LOL

That is another story.

If the shift like you should be OK.

For me - I would have to upgrade

 

ive been quoted for a front clip for 2550.00 shipped to florida, for a mach/series 5

Yeah if i did get the SC then i would probably have to invest into a new tranny and rear end becuase i would have a hard time being gentle on it.

Yea... your wrong not all superchargers rob power

Thats only one type of sc, not all of them have that drawback

 

prove it. how can a belt driven accessory not rob power?



even top fuel dragsters' superchargers rob power. (the s/c on those cars rob more power than any of our cars make)

 

The higher exhaust backpressure caused by adding a turbo 'robs' power too.



If you put more power to the wheels after adding something, does it really 'rob' power? I'd say it increases power.

 

The more i think about it the more i like the idea of a SC on my NA. I think that will be my goal now, not a lot of people have it. Granted i know that a turbo would get me more power in the long run but it will still be fun and somewhat unique. Just trying to have a good time.
