Hey guys. I seem to be running out of gearing at my track. We have a huge straight and my MR12 is just straining towards the end of the track. What is the ideal spur/pinion combo to run? I'd like to keep the 1st gear the same if possible.
How long of a straight are we talkin. I would say a 1 tooth jump would be enough if its around 200ft, you also might wan't to get a RPM pipe as well to help the engine.
