TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

OMG awesome! I love the look.

 

With as much power as you're making, I would be stoked with 10mpg!

 

Shortly after I bought my truck, my wife drove it and stated that it was "kinda" weak. Keep in mind, for 10 years she drove an '02 4Runner 3.4l, then I moved her up to a '13 5.7l Hemi Durango.
I used that as my green light for installing the S/C.

 

Ahaha. I'm pretty sure I can see the fuel gauge moving when I floor it in a high gear at high RPM....

 

It's almost like she was telling you to buy one!

 

Highway speeds in Seattle rarely Crest 25. I get crap mileage idling.

 

That's a sign that you're doing something right

 

Dang, that definitely puts a hurt on the mileage then. Are you running stock gears, or have you regeared? Stockers with bigger tires like you have kill mpgs too

 

Stock. Gears are part of the plan.

 

have you decided on a ratio yet? I want to put some 4.10s or 4.56s in mine, but I don't plan on runner tires bigger than 265/65/17s. I just want more torque!

 

That's the way I heard it...

 

I dont know what I have. I want only the next size different.

 

you have 3.73s

 

If you find a 2nd gen 4cyl 4x4, those come with 4.10s from the factory

 

@rjbiii you want to go shorter than stock for diff gearing? Like 4.1 instead of 3.7?

 

I do.

 

Fun stuff.

 

Older video I found 50-90 almost.

Be careful with the gear selection. I just went to 4.88's and 34's and the most I can must on the highway is 15mpg if I keep it at or below 65mph. At 80mph I get 12-13mpg. In town I get 10-11. But it pulls the camper great! And I weighted my setup before we left to take it up to the mountains for hunting last weekend. Truck and trailer with no water in the tanks, 13,340 lbs. Truck had full tank of gas, two 5 gallon jugs of gas, and a small generator in it. Camper had food for me and my clothes and 21 gallons of water in jugs. Loaded with water and stuff for the family, I bet I am over 15K! Love my Taco!

 

As @mr.trd said, I'd be careful. Torque is nice but if you are only running stock 31" or even 32" tires I wouldn't touch it, first off re-gearing isn't exactly cheap and the big one is your highway mileage is going to take a beating. Power is great but has its drawbacks, reliability and fuel mileage to name a couple. My truck can tow my RV trailer, or boat great, plenty of power, but do I use it..Heckkkk no! It's towing fuel mileage is absolutely horrific. It stays it boost wayy too much. Thats where the diesels or bigger displacement motor shines. In my case the V8 runner does the towing.
