Re: Custom Supercharger Pulley Advice for 5.7 FJ Build
I have the TRD Supercharger on my Tundra, the engine, transmission, and transfer are near their practical torque limits at the 550 rating. Which in itself is impressive for stock 1/2 ton equipment. You will need to go inside the engine and install a minimum of new pistons if you want to take it further AND have reliabilty. I'll also mention that there is a lot more power on the table at the current boost level. Air flow/volume is where it is at, not psi. If you need any other info, just ask.
