The Magnuson supercharger kit for the Toyota Tundra 5.7L is an absolute work of art and must have modification for this truck. Coming from the factory with 381 horsepower and just over 400 ft/lbs of torque, the V8 is strong, but not strong compared to other trucks in its class. Newer vehicles such as the 2017 Ford Raptor with its 3.5L turbocharged EcoBoost push out 450 horsepower! Magnuson answers back with their bolt-on kit giving you over 500 horsepower with 550 ft/lbs of torque. Can you feel the difference? You better believe it! The finely tune, OEM like kit livens the Tundra up like it should have come from the factory. Surpassing the original TRD supercharger in power, drivability, and performance. Magnuson has kits for both the Flex Fuel 5.7L and Non Flex Fuel 5.7L vehicles. The main difference in the kit and installation is the fuel pump upgrade for the FFV trucks. The kit is a true bolt-on that does not require any additional products. Complete with a well calibrated Bully Dog tuner, the kit is even CARB approved for those residing in California. Having previously owned a VF Engineering supercharged BMW M3, expectations of a high quality supercharger kit were certainly met with the Magnuson product. The installation of the FFV kit took about 10 hours by our friends at Earnhardt Toyota who love aftermarket parts. Everything is well labeled and the instructions are very easy to follow. Doing the Bully Dog ECU flash requires them to remote in to your PC to download the original binary from the car and then upload a new tune which is all done via the OBDII port.
Upon completion of the installation, I jumped in the truck and got after it. The charger has a nice whine to it and pulls like a freight train. Drastically different than a TRD Supercharged Tundra I test drove. The torque is very strong with linear power all the way through redline. Fuel economy when you are not driving like a wild person actually slightly increases. However its hard to see that gain as the power and performance of the Magnuson is to much fun to not use your lead foot! What makes the kit even better is that Magnuson offers a 3 year/36,000 mile warranty and for an extra amount you can purchase a 5 year/60,000 mile warranty that covers the entire powertrain! The decision to do this supercharger was everything expected and I highly recommend it. Without this performance, it would be just another Toyota Tundra.
