Every long block or engine is now CNC ported and hand finished. CNC porting and hand finishing is all done in-house by the OBR staff. We do not contract out any of our porting so every engine is modified to our exact specifications. We are able to offer higher accuracy this way as well as more power. Our CNC machine has allowed us to take our porting to the next level due to us being able to do cylinder work that is not possible to do by hand. Due to high demand, there is a lead time on all of our reed engines. Please contact us prior to ordering if this is an issue.

This engine will come with a CY fancover for a direct fitment into an HPI Baja, Losi and most other large scale rc cars. Available with out clutch or with the correct clutch for a direct fitment into your large scale car.  We are extremely proud to release the TR/OBR 4 bolt reed case. To start, we would like to thank Dave at Turtle Racing and Yamadude for all of their hard work that it took to make this happen! Dave has spent countless hours and late nights designing the many prototypes that we went through making these cases to perfection.

This is not a knock off or slight redesign of any current reed engine. Though there are only so many things that could be changed while still being able to fit into our 1/5th scale cars, there is a lot more that has gone into these cases than most will realize. Yamadude stepped in to assist and was a huge help with design and flow bench testing. Many prototypes had to be made to achieve the ideal intake track for the best possible flow. Between the help of Dave and Yamadude, that gave us the tools we needed to give you all more power! For those of you not familiar with our history we are coming up on our 10th year in business. We take a lot of pride in every engine that ships out of the OBR warehouse and we feel this one really reflects what we are capable of building.

The development of this case took several months, a lot of labor, testing on our dyno, in-car testing and we could not be more pleased with the final product. We have seen horsepower and torque numbers we never thought possible out of engines this size. We are seeing quite a bit more torque and rpm’s as good, if not better than, our piston port long rod engines.  Tech note: Both the CY & TR/OBR  clutch can be used for an HPI Baja, Losi, Rampage etc. Choose a Zenoah clutch for an MCD or FG. 

An aftermarket filter is recommended for install in a DBXL!
