I was running a Murnan 35 Plus 21 at 301. I ran this same motor 4 weeks earlier at the RC Pro Series at 301 and ran a few 19.95's. Well after practice and the 1st day of qualifiers, I ran several 19.9's and all low 20's. Car was same setup as 4 weeks earlier except I had a better idea on tire size and gearing. I was hoping to do some 19.7's, but never got that before sucking a couple plugs and hurting my motor. Uriah let me borrow his 359 mod and I was very pleased! After tuning, and poor driving on my part, my 3rd qualifier on day two was balistic but my tuning was off and I ran out of fuel on my 15th lap. It was about a 15 lap 5:10 pace. After more tuning, I easily made 5 minutes and in the main, I came in at 5:10 before my mistake. I ran a few 19.7's with that motor and nothing was changed on the car. I had a great main until my brain fart and I missed my pit window. In the main, I ran a 19.6 and my overall lap times were better by about .2 - .3 tenths on groups of consistant laps.
I love both motors, but IMO, the 359 is smoother. All my clutch setting were the same for both motors, same fuel (Rocket Science)
, same tire size and gearing. The 359 has less torque out of the corners, but I made my time up in those areas because I wasn't spinning tires as much as the 35 Plus 21. The car seemed slower but, the car was accelerating down the track quicker since the power band was smoother. Not to say the 359 doesn't have torque, but the 35 Plus 21 is has crazy torque. The top end of the 359 seemed stronger than the 35 Plus 21, but that was hard to tell.
Since I was on 37 Kyosho tires, my thoughts are the 359 was better for those tires. I probably could have controlled tire spin by softening the clutch(why) or go to 35 Kyosho tires to run the 35 Plus 21. Tire wear would then be high and a possibility of traction rolling. Uriah ran 35 and didn't roll, and he makes look real slow at times, so I probably wouldn't roll either.
Overall, both motors are super sick!!!! I believe I prefer the 359 at this time due to the smoother feel and how I set my car up. I like both, but you can't go wrong with any of Uriah motors.
Thanks for your help Uriah, a new 359 is needed for GLC baby!!!
