We have tested these motors on the track and on the bench. A few things we have observed. The PTS motors are indeed making a little more power than the PT. We see about .1-.2 sec per lap between the PT & PTS. The new engines (PT&PTS) are a little faster than the 2010 engines like the Flash Special or 35 plus Tuned. Some of the advantage comes from the fact that the new engines have a broad power band. They have good bottom end torque but continue to pull longer than the 2010 engines. We were able to run 1 tooth bigger 2nd gear spur so we had better acceleration in the short chutes without losing top speed. We used the same gearing for 1st.
You have compared 2 different engingines, how much do you expect they are excactly the same? Novarossi makes the engine with steel bearings by means a little bit slower so people have to buy the most expensive one If they made excactly the same engines then they know the 100 dollar more expensive engine will not sell.
I was told by 1st hand the ceramic bals they use just cost 11 cent a piece....
If you would be so nice to use 1 engine and change the bearings on that I wonder if you still would notice the difference.

Well, actually RPM is power. It is the goal in the F1 if there were no limits. RPM x Torque = power

A good steel bearing runs better than a bad ceramic one. Every bearing made bij INA, SKF and name them all you can get them in all kind of specs and the specs can tell you every detail of all components in the bearing. I have never seen this with Novarossi so with the current short lifes the original bearings have you can ask the question how good the quality is.....
And yes, I have changed from ceramic to steel also without any issues.
