Apexi turbo timer on Supercharged S?
Is there any benefit to have one. I know it is important to cool your turbo and engine with a turbo application but how about with a supercharger? It was nice to have when I had one on my fd3s rx7. Anyone here use one? Here is a link where someone is using one.

That's why it's called a turbo timer.

what? The turbo doesn't spin with the engine off either. The turbo just has hot exhaust air running through it and the S/C does not. If the oil isn't allowed to run through the turbo to cool it down a little it will damage the turbo. The S/C doesn't get nearly as hot you can still put your hand on it after hard runs, whereas on a turbo you can't even put your hand near it without feeling a lot of heat.

Sorry dude, The wheels in the turbine are still spinning after you shut the engine off. The turbo is not mechanically linked to the crankshaft like a SC. A turbine wheel spinning at 20,000+ rpm doesn't stop moving when you shut the motor off, it take a while for it to slow down. Turbo timers are used to allow a cool down period for the turbine, and to prevent from cooking the oil in the turbo at shutdown.
