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.

We've reached our power goal. Take a peak at how we did it, and be prepared for a smorgasbord of dyno graphs not only from Project Supra, but from other Supras and racecars tuned at Modified by KC as well!

One of the markings of a better shock company is if the company can service their product by offering rebuilding and revalving if the the customer needs it for their usage. We recently visited Tein Suspension since they are rebuilding and revalving the shocks on our Project Supra.

Our Project Supra is back! We finish the fuel system, install a new AEM Infinity EMS, break-in the engine, refresh the suspension, make initial dyno pulls, and more!

With the engine almost fully complete and near-ready for start up, now's not the time to skimp! Check out our new fuel and engine breather systems, ensuring we get the most out of this 2JZ!

Check out why the Supra decides to chill behind an ETS intercooler. It's more than just about "bigger is badder".

With all the parts needed to move forward, Project Supra is now on pace to get fired up! Not only are previously featured parts installed, but we continue to add new stuff as well.
