How does the risks (on overall engine problems) of the aftermarket turbo compare to the aftermarket superchargers being offered.
The supercharger systems leave out the intercoolers. That's what makes them even more risky, and is what makes the price so attractive. My own thinking is if one were to use an 8:1 compression ratio and an intercooler with the supercharger, the longevity of the engine would not be terribly different from that of a Turbo. Of course, then the modifications are no longer a bargain. And aren't some internals of the Turbo made using stronger alloys, or insert sleeves for the pistons?
I, too, crave more power. But until I reach the point where financially, I can shrug off a blown engine, I will enjoy what I have. And if I ever do reach that financial status, I'll buy a Turbo and be done with it.
