About Magnuson Superchargers
At Magnuson we believe you should be able to have big horsepower, drivability, and a long-lasting, reliable product. In fact we’ve been making power you can live with for more than thirty years. We’ve used what we learned to develop Magnuson Supercharger Kits – the best-selling, most complete line of bolt on superchargers anywhere. We test each Magnuson Supercharger before it leaves the factory, and we stand behind our product with a 3 year/36,000 mile warranty.
Supercharging to OEM Standards
It’s going to run like it was factory installed because we manufacture and calibrate to OEM standards. Just ask our OEM customers. We also use Eaton rotors exclusively – the same supercharger rotors found in virtually all of the OEM supercharged applications from Audi, GM, Jaguar, and Ford. Most Magnuson Supercharger Kits carry a CARB EO# and are 50-state emissions legal for on-road use. Magnuson kits are known for their drivability and reliability, achieved through our Powertrain Integration approach. Simply put, this is the process of recalibrating the engine and transmission control programs to work with the altered induction path and boost pressure of the supercharger. This results in a seamless and consistent delivery of power over the entire RPM range, not just high end. It also means that your vehicle will continue to meet emissions and fuel economy standards.

Our Experience Installing a Magnuson Superchargers a 2017 5.7L Toyota Tundra
Here at Low Range Off-Road we decided to put Magnuson’s claims to the test. Former employee and friend Jesse Floyd of Mapleton, Utah had just recently purchased a 2017 5.7L Flex-Fuel Toyota Tundra and expressed an interest in installing a Magnuson Supercharger. So we decided to partner with Jesse on the project; he’d supply the truck and parts and we’d supply the shop and give him the supercharger at our cost plus a little. We also wanted to video the project and make a highlight video of the entire installation and testing.
We found Magnuson’s step-by-step, full color instructions (click images below to view or download) to be some of the best we’ve ever used. These instructions are accurate and detailed; complete with measurements, torque specs and tech tips to make the job go pretty seamlessly. The hardest part is patience. The itch to feel the added horse power, makes completing every step almost overwhelming; but be patient, is worth the wait!
The kit was very complete. The only thing we needed to buy was some Toyota Approved Coolant and some anti-seize compound for the spark plugs.
The install took the better part of two 8 hour work days, but it could have been done a lot quicker if we were not filming the entire process (See Video Below). I have heard estimates of 10 to 12 hours to complete the job from start to finish.
Prior to the installation, we did a 0 to 60 MPH test and a Dynamometer (Dyno) test to give us a fairly accurate idea of performance improvements (See Video Below). Our 0 to 60 test resulted in 8.10 seconds. The dyno test measured 292 Horsepower (HP) and 361 lb•ft of torque (Max Torque) to the rear wheels.
After the installation we took a road trip from Orem, Utah to Bully Dog Performance in American Falls, Idaho to have the Tundra’s computer remapped. These guys at Bully Dog really know their stuff. It is amazing how much difference a little tweak here and there in the engine and transmission calibration can make in the overall performance of the vehicle. Going to Bully Dog is not normally required, but they offered to do this for us since they needed a test vehicle to develop the tune for the 2017 flex fuel engine. This mapping had not been done before, not even by Toyota. This is why Toyota is declining to install this supercharger on any Flex Fuel model Tundras. At least as of right now.
After remapping the computer, Bully Dog techs did a follow-up Dyno test that resulted in 476 HP and 467 lb•ft of Torque to the rear wheels. This was a net gain of 184 HP and 106 lb•ft of torque. The 0 to 60 test resulted in a much quicker 5.17 Seconds. That is 2.93 Seconds less than the first test.
Some have questioned our dyno test results pointing out that Toyota claims the engine will produce 381 HP and 401 lb•ft of torque completely stock from the factory. Interestingly, Toyota’s figures are based on output at the engine crankshaft not at the wheels. There can be as much as 20% power loss through the transmission, transfer case and differential. Consequently, Toyota’s specifications measured at the engine will be significantly more than what a dyno will measure at the wheels.
If you are considering doing this job yourself or having it done by someone else, let us give you a couple of suggestions. Be sure to run at least one tank of 91 octane or better fuel through the motor before this install is done and continue throughout the life of the engine. If you run a lower octane fuel after the installation, you could damage the engine. Additionally, to further reduce the risk of engine damage once the supercharger is installed, be sure to plug-in the Bully Dog Performance Tuner and complete all the steps needed to re-map the ECU before installing the supercharger. You will need a laptop to install this new Bully Dog computer map. And then last of all, if you have a choice in which Tundra to purchase, the flex fuel model is an easier “install” since you do not need to drop the tank and install a higher output fuel pump and you do not need to change out the injectors.

We also supply Magnuson Supercharger Kits for the 1995-2004 Toyota 5VZ-FE 3.4L V6.
And the 2005-2015 Toyota Tacoma 1GR-FE 4.0L V6.
