turbo to blower

[SleeperZ31]

okay, i know the following question may seem stupid:icon45:, and im sure ill catch some flak for asking, but centrifugal superchargers are almost identical to turbos except(obviously) the blowers belt driven and spins the impellers with a internally oiled(usually) gear drive system whereas the turbo is exhaust-gas driven, and im looking to supercharge my car (turbo-ing it would require me to ditch my awesome header/catback setup i just bought)

 

...sooo i was wondering if anyones thought of possibly taking a good condition turbo and machining it to be belt driven? what all would i need to do to get it to operate reliably without overheating/ oiling issues, etc...and would i need a larger turbo to make as much boost as a smaller one being exhaust driven..

 

or better yet if anyone could find or sell me a decent used centri' supercharger thatd be great too..

 

again i just like to throw ideas out there, some of 'em might seem stupid but im always thinking and this forum is a nice place to vent..

It's far better to just buy the super charger because of the gearing required to achieve the rpms the the compressor makes boost. Other than that, just treat it like a turbo intake.

yeah, thats why i like the idea of a centri', sure it makes boost a little less responsive than a standard roots style, but the centri' is pretty much adaptable to anything AND WAY easier to intercool, the only problem is their so damn expensive compared to roots and turbos

I think a turbo impeller shaft is way to weak to withstand pulsations from a gear driven system. It wouldn't be worth the effort...

Ford thunderbird superchargers (M90??) show up on Ebay all the time for DIRT cheap.

I suggest Corky Bell's book on supercharging...(never read it, but I have his turbo book "maximum boost" and it is great)
