In the last edition of Project Tundra, we had installed Hellwig's adjustable rear antisway bar in an effort to improve our truck's balance and limit body body roll to help keep our stability control from activating prematurely.
Now to finish up our chassis tuning we wanted to address a problem all trucks that tow have. With tongue weight in place the back of a trucks sags lower and the front lifts higher. This makes the handling a little squirrely at times, the steering getting light a lot due to the geometry changes of the front end when under droop. The heavily loaded rear suspension is also prone to bottom out with bigger enclosed trailers which can make things interesting and possibly damage the trailer jack.
To fix this by leveling out our truck without hurting our ride, we decided to go with a set of Hellwig Big Wig air bags. The air bags can increase the rear suspension's capacity by 2700 lbs and restore the proper ride height improving stability and laden ride. When finished towing, the bags can be depressurized for a stock ride height. and smooth ride.

If you have been following Project Tundra, you know we have been struggling with excessive activation of our truck's stability and traction control systems. The improved power of our supercharged engine and additional traction of our larger tires have been driving the electronic nannys of the truck's OEM systems crazy. We were hopeful that a new adjustable rear antisway bar from Hellwig would help.

So as we alluded to in our last article, our powerful supercharged Tundra without a limited slip was continually activating the Trucks electronic nannies. With the more powerful engine, the electronic LSD was working the rear brakes constantly trying to keep one tire fire under control and with the added cornering forces that our bigger tires allowed, the stability control was grinding away at the front brakes in tuns all the time. The electronics were probably causing the brakes to be used at twice the normal rate.
We had tackled some of the issue by limiting body roll with a Sequoia front and TRD rear anti sway bar and turning up the stiffness of our King Adjustable shocks. Adding an Auburn Gear Limited Slip Differential also helped a lot to keep the electronics from grinding away at our brakes. However our brakes and rotors were shot with the rear brakes worn to the backing plates and we had to replace those ASAP.
We turned to Stoptech for some help in the brake replacement department with some new rear sport rotors and some less aggressive brake pads in the hopes of reducing brake dust and rotor wear for this brake service period

Supercharging Project Tundra is one of the best things we have ever done to any project vehicle in the MotoIQ fleet. The TRD supercharger has proven to be totally reliable in thousands of miles from towing up hill in blazing heat to driving all over the place. It has also proven to be economical as our normal driving gas mileage has not changed at all. If anything the large amounts of power have had only one negative effect on the truck, no traction. To help deal with this we obtained the only limited slip diff on the market for late model Tundra's, the Auburn Gear HP Limited Slip Differential.

Project Car Update: The V8 Edition
By Colin Holte
A quick glance at the project car column should tell you that MotoIQ has a large (and ever expanding) roster of project vehicles. With all these vehicles it can sometimes be tough to keep the updates flowing for each. In some cases vehicles may have even been sold but we still keep them on the project roll for posterity. These articles are intended to share a little bit of the details with you of where some of the project vehicles that haven't seen the spotlight in a while are at in their evolution. In this installment we check in with the V8s: Project Mustang V8 5.0, Project Tundra, Project V8 RX-7, and Project Lexus IS F.

Project Toyota Tundra Part 10- Suspension by King Shocks
By Mike Kojima
When we last left off, we had installed bigger brakes as well as wheels and tires on Project Tundra. The big wheels left us with rubbing problems which we addressed by moving the fender liners and modifying the front crossmember. We wanted to get even more wheel well clearance so we decided to raise our truck slightly. The stock Tundra has a nose down attitude which looks a little funny so we wanted to raise the front of the truck by about an inch. We did not want to build a Metal Mulisha bro mobile, just raise our truck a little and improve handling if we could.
To do this we decided to get a set of King Offroad coilover OEM replacement shocks. The King shocks were designed to maximize performance on a stock truck at close to the stock ride height. The King Shocks were designed to run at the stock rear ride height while raising the front about 3".

Project Toyota Tundra Part 9- Installing TRD's big brakes & Volk Wheels
By Mike Kojima
When we last left off we had just gotten our TRD big brake set and were anticipating installing them on our Project Tundra Supertruck. However our brakes were so big we could not fit them under our forged 17" TRD wheels. It was not even close. Checking with TRD we found that the smallest diameter wheel we could use was a large 20" in diameter wheel.

Its been a long time since we last visited Project Tundra. Our super truck has been performing admirable duty around MotoIQ headquarters as our company workhorse. It has been towing cars around, toting go karts and hauling parts for the past year without complaint. Our Supercharged Tundra has been flawless in performance and reliability even getting slightly better than stock fuel economy.

In a flashback Friday we're taking you back to when we turned our Tundra into a "Huge fast house" and showed an Evo driver who's boss. We have been building our Project Tundra into the ultimate towing machine over the past year with the help of Toyota and TRD. Toyota and TRD’s accessories including the supercharger are great in the fact that they do not affect your warranty and can even be financed at the dealer at the time you purchase your car if you are so inclined.

When we last left off on Project Tundra we had installed a TRD cold air intake and TRD exhaust system. We were enjoying the high quality, warranty friendliness and smog legalness of our TRD factory engineered performance parts. However being how we are we still wanted more. In our search for the ultimate tow and work vehicle, we obtained one of TRD's awesome supercharger kits.
