not a SC expert by any means, but should you get a turbo timer for a SC? Another way of asking this would be: does a SC need to cool down the way a turbo does? If this makes me look like a jackass, fine, just answer the question.

 

No need for one

 

The vortech s/c on my stang was tapped into the oil pan and was cooled by fresh oil.. Not sure about the Vortech on the Z.

 

same thing...oil cooled

 

Good question, actually...

Turbo impellers are turned by EXTREMELY HOT exhaust gases. Impeller bearing temps become high after hard running, which challenges the circulating oil's ability to keep the bearings cool even as it circulates.

Without a cool-down period, stopping the turbo stops oil from circulating. The oil pooled around the bearings absorbs more and more heat from the bearings. It's only a matter of time before the oil pooled around the bearings absorbs enough heat to scorch, or coke. Oil coked on the bearing surfaces will cause the bearing to fail. A turbo timer keeps the turbo oil circulating during cool-down, to help keep the circulating oil from super-heating and coking. (Water-cooled turbos do not need a turbo timer, since the water draws heat away from the oil and bearings through convection. The oil will not get hot enough to coke as a result.)

A supercharger is driven by a belt, so contact with HOT exhaust gases is not an issue. Circulating oil may become quite warm in a supercharger, but not hot enough to scorch/carbonize/coke as in a turbo. So no extended cool-down is necessary. So no turbo timer is required.
