[QUOTE="NiK_0, post: 514027, member: 8583"] From my previous experience with supercharging an LX470... increasing boost above 8psi is not worth it. The engine and A/T life is severely shortened. Even if you invest in an engine rebuilt with stronger bottom end, tranny rebuilt with stronger disks/plates and pressure... the overpowered engine will offset the balance of the truck. Yes, sure, you'll last longer, but will blow up eventually... My previous car, LX470, lasted 50k km w/16psi pulley. Sure it was lifting its front tyres on take-off, but eventually, exhaust manifolds gave in, A/T went loose, and we blew the engine due to Toyota's F&#^k^ng stupid policy of encrypting its ECU. HATE TOYOTA FOR THAT! LOVE GM and FORD that they implemented ECU retuning from the factory! The good idea, I believe, is to increase the power to a safe level which should be about 30% below maximum tolerable by the drivetrain. 502 at the wheels is already a lot. But for the heck of it - yeah, try it, let us know the feelings! :) [/QUOTE]
