Triple Turbocharged 650ci Six Cylinder | Super Stock Pulling Tractor

June 01, 2021

It is no secret that FuelTech engine management systems are used on some of the wildest and craziest vehicles in the world, including NHRA world championship racecars. Recently, the team at the Ball Ground, Georgia facility worked with one of the most unique vehicles to ever be bolted to the in-house Mainline hub dyno—a Super Stock pulling tractor from GALOT Motorsports. FuelTech’s Technical Director Luis De Leon walks you through the intricate workings of this unique and extremely powerful pulling tractor combination.

The body remains largely stock appearing but under it resides a 650ci six-cylinder engine that uses a DT466 engine block out of a school bus and is topped with a billet cylinder head featuring HEMI style combustion chambers. There are three Harts Turbochargers, which are run in a compound format and produce as much as 120 psi of boost. As if that isn’t cool enough, they dumped the diesel fuel in favor of straight methanol. Cutting right to it, the powerplant maxed the torque output of the Mainline dyno at just 50 psi of boost!

The GALOT Motorsports tractor has been outfitted with a FuelTech package that is similar to Pro Mod racecars, which begins with a FuelTech FT600 engine management system to help control the insanely powerful six-cylinder combination. The all-in-one ECU is a valuable tool in the high stakes pulling game, especially when big money is on the line. The FT600 along with the other PowerFT ECUs—FT550, FT550LITE, and FT450—offer sequential injection and ignition, O2 Closed Loop, data logger, delay box, Boost Controller, Nitrous Controller, and so much more. The FT600, FT550, and FT450 have a customizable digital display for the driver and the anti-glare TFT touchscreen offers the ability to make adjustments to the tune without hooking up to a PC computer.

Life begins at 100 psi in the compound boost game, making the ignition system a critical component. The team went right to the top with a FTSPARK EXTREME, which is the most powerful ignition system on the market—even more powerful than single and dual magneto ignition systems. It produces a minimum of 1,500mj and has a maximum rating of 1,700mj, that is a guaranteed 250% greater output than the FTSPARK Gen I. It will also provide 175 amps of current at the primary coil (40 percent increase over FTSPARK Gen I). The FTSPARK Extreme box features four channels, requiring two ignition boxes for eight cylinder engines (sold separately), a set of ignition coils, and a plug kit.

Data is a very important element in keeping the rowdy in-line six performing at its peak and the FT600 data logs dozens of channels. One of the components that helps gather data is a FuelTech EGT-4 CAN module.

From NHRA championships on asphalt drag strips to a wild triple turbocharged, compound boosted Super Stock tractor on dirt that pulls a 60,000 pound sled, providing reliable and innovative solutions is why you’re seeing #FuelTechEverywhere
