I ran the MMP last night in 17.5 touring car and I am impressed at how smooth the power is. I ran an Orca 17.5 with a fdr of 5.01 on a 36'x80' carpet track on rubber tires and came off at 143 f. I was only one tenth off of my best lap time with a Tekin RS. I am going to try to gear up a tooth and play around with the rpm settings a little more, I am sure it will be even faster.
