We have taken our standard championship winning B2T 2WD Transfer Case and made it into a 2 Speed with a simple conversion to the existing unit. By adding a 2 3/4" spacer between the main case and the cover, we can convert the B2T into a B2T2. It is reversible, in other words, you can always go back to the B2T.
Rob MacCachren and his crew chief Jim Blackmore were the first to commission a B2T2. Competing in the LOORS Unlimited Pro-2 14 race Championship, Rob won 7 races and finished second 3 times.
Rob won the Pro-2 LOORS Championship with a couple races to go with zero failures with our prototype. As a reward for our hard work, LOORS has now BANNED the B2T2 for 2017 and beyond.
At any given track, the racer must first test to find out the best overall ratio for the track. So you can pick two different Overall Gear ratios and go out on the track to find out which one works best. The quick change option allows the racer to quickly change ratios and dial in the truck.
Keegan Kincaid finished 2nd in the TORC Pro-2 Championship after picking up the second prototype B2T2 midseason. Kincaid dominated in the two 2WD vs 4WD Cup races at the Big House in Crandon, Wisconsin.
One option is to gear the truck for slippery and tacky conditions. So at the beginning of the race, when the track is at it's slickest, you would shift into high range and take some torque out so you won't slip the rear tires as much. Then as the track gains traction, you could shift into low and put some torque back into it.
Once back into low range, you have the further option of selecting the high range in each gear, basically turning the 3 speed automatic truck into a 6 speed.
Not to be confused with the planetary overdrives, the B2T2 is a spur gear underdrive that can be geared as an overdrive.
