Dyno results are in. We've had quite a few questions on the power difference between this billet case and a stock Zenoah case. We're seeing by just swapping to the TR/OBR billet piston port case more power all the way across the board. 0.2 ft/lbs of torque and HP, broader powerband, +1500 rpm's and quicker crankcase temperature dissipation. You're not going to bolt this case onto a stock engine and turn it into a full mod or anything but you will see a noticeable difference in power. All excess volume has been pulled from the case to give your engine more power. One of our favorite features is the three piece case design. Over our many years with large scale rc cars, we’ve seen our fair share of cracked crankcases. The TR/OBR reed case has a replaceable fan cover mount incase you ever crack or break it. This is a much cheaper alternative to replacing the whole or half case. We recommend any displacement Zenoah 4 bolt top end to match this case. Works with 4-bolt top ends only, not compatible with stock "2-bolt" top ends.   Comes complete with bearings and seals installed. If you have any stock or ported Zenoah R/C engine this case can be swapped with no modifications. These cases do not use a crankcase gasket. Cases need to be sealed with a good sealant. OBR's sealant of choice is Threebond 1211. Note: This case is not compatible with the new G320RC engine. For the G320RC crankcase, see part number dd400b

When used in the Losi DBXL you need to use the TR/OBR DBXL Engine mount db150B for correct fitment.
