PRW low-profile Engine Test Stands (ETS) with short block adapter allows the mechanic to "build" the short block, and then rotate the engine to the upright position, just like a typical engine stand. Then, temporarily support the short block and install the center supports, remove the rotating head unit, and re-attach the rear engine supports to finish the engine assembly. After final assembly, install the fuel cell, plumb for fuel, wire the electrical, connect the battery, and you are ready to run! Obviously, this over-simplifies the necessary preparation and hard work; but a great deal of satisfaction can be gained with the knowledge that your engine is ready and worthy to be installed in your hot rod, race car, street machine, truck, boat, or off-road vehicle. The patented collapsible design of the ETS is manufactured with standard parts and readily available replacement parts from the manufacturer. They offer space-saving benefits when collapsed, making them ideal for the small shop or race trailer. PRW low-profile ETS are designed to accommodate most engines and built to meet the demands of high-output racing engines and heavier big blocks, taking mobile engine test stands to a whole new level of functionality.

TCI Super StreetFighter transmissions bridge the gap between the StreetFighters and full Competition series transmissions. Like the StreetFighter units, these are equipped with 100 percent tested, manual/automatic valve bodies. That means that most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears and shaves time off your ETs. When you use the manual gear selection feature, the Super StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, the transmissions retain positive automatic shifts, for the ease of driving you look for in an automatic transmission.
