Not this forged vs cast convo againthe tundras who blew rods almost all put on a smaller pulley and were running higher boost than the system was designed for, resulting in the blown rods. More superchargers were put on tundras than on 100s. Do the math. I would run a supercharger with the stock pulley on a 4.7 with no concerns.
All 4.7s use the same rods.
I stand by my statement. I spent almost an hour reading various stories on the internet relating to trd superchargers, while watching the latest episode of duck dynasty, which was the thing at the time. Soooo I think that means I’m pretty much an expert on the subject.
Looks to me like the forget one has more mass. That has to put extra loads on bearings/connecting rod. I would suspect a shortening life of the engine.
Sorry, I guess I should have been more specific. I know TRD stopped making the 4.7 Supercharger years ago. I don't care if the supercharger says TRD on it. I'm just curious whether or not the stock USD 4.7 can handle a bit of boost.The TRD supercharger is not designed to fit your 2005 vvti engine.
