Does anyone know if a turbo with a mechanical seal can be used in a dry blow- thru app. or does it need fuel for lube or cooling the seal, I would think it would be OK?
 
The turbocharger for the 62-66 Corvair is a draw-thru and is sealed. It can be and has been used in a blow-thru system.

A turbocharger for a blow-thru system usually can't be used in a draw-thru setup because of the lack of seals for gasoline.

Hope this helps.

I’m fairly certain it’s not the gasoline that’s the issue, it’s the off boost vacuum that’s generated pulling oil into the intake tract because the turbo is seeing vacuum being below the throttle plate.
