My thoughts exactly....thanks for validating my feelings. Since I will keep my 95 after the next rebuild, I may do it then.Rich said:It is never too late.
You can "harm" an engine without a supercharger, so you will certainly be able to harm it better with a supercharger.
Any increase in power delivered reduces the potential life of the engine. That is always the tradeoff.
If you are really asking, "What will be the likely reduction of engine life due to adding a supercharger?", I would be surprised if anybody can provide an honest and accurate answer. Toyota may know. Bet they won't tell you.
Others can share stories of engines breaking shortly after installing superchargers. I think those experiences are in the minority.
