Ivet ried both on my sct 78/28 with 40deg timing and 78/24 with 55deg and liked the torque alot more with the second one but think i need a little more timing....
On my buggy i run 69/33 and i have plenty of torque and speed combo i can clear all jumps with a blip of throttle
Both are losi 2.0 vehicles with 2.43 trans ratios i believe
