Rotary Hillclimb Racing

Getting ready for 2011 Hillclimb season in the rotary hillclimb racing car.

The rotary hillclimb racing car need to be re-freshed to get ready for the 2011 hillclimb season.  During the 2010 Noosa Historic hillclimb in November the engine suffered over heating problems after that event the engine developed a knocking sound in the front rotor. Curious to see what had happened, during the Christmas break I stripped the engine down to see what the problem was. The front rotor bearing had spun inside the front rotor damaging the crankshaft and the rotor. This was not good news as I would have to replace the crank and the rotor.

Fortunately I had a spare engine and that I stripped and cleaned then I gave it to Ben Hunt at Rotary Motorsport for him to rebuild. The rebuild consisted of Ben’s own porting, internal dowelling and internal rotor modification all hoping to make the engine more reliable. Ben also suggested that I fit an external oil cooler to help with the cooling of the engine.

I received the engine back from Ben all wrapped ready for installation, then set about installing the engine to the chassis. When I had the engine installed, the car was given back to Ben for finial chassis dyno to check to see if all was ok and to re-tune the new ported and modified engine. The finished results were very impressive with more power and more torque available out of the new engine due to Ben’s porting design including the internal modifications that he has done during the rebuild.

I would like to thank Ben Hunt from Rotary Motorsport for his engine building and tuning expertise, as without his help and support for the rotary hillclimb racing car I would be not running the first round of the Hillclimb series.

The next thing that I needed was to get a wheel alignment to make sure that that all the road wheels are pointing in the correct direction, to get this done I booked the car in with Bruce at Leda Suspension at Brendale. Bruce set the alignment of the car to the optimum setting.

Now the car should be ready for the first round of the Hillclimb series at Mt Cotton on the 19th & 20th of Feb 2011, I hope to see everyone there ready for a great year of Hillclimbing.
