CS Powercheck

I have been offered a CS Powercheck dyno, used at a fairly reasonable price but I have a couple of questions hopefully someone will know the answer to;

1. The m/c starts up at v1.1 s/w is this the latest version? (the PC s/w is at v1.5 and I know that it is the latest)

2. I have been told by CS when running 10 turns or less to use 2 battery packs in parallel. Has anyone tried this and does it make the results strange?

3. What tips do you have using this unit?

Thanks in advance!

the problem is that this dyno test the motor in vertical position while you run your motor in horizontal position. i do think this is not the way we should dyno a motor.

you read my mind! I'll make sure the flywheel is vertical first with a spirit level!

It wasn't displayed in the shops. Someone is getting rid of his electric stuff! I have the unit for a 'test run' this weekend.

Manticore- well I did do the test! With the motor vertical the max power comes in at around 2000rpm higher than in the horizontal position, the actual power level was very comparable. Besides that there was very little difference between the two tests. Max power, amp draw, rpm etc was very comparable.

I also did the 1 pack/2 pack test. Strangely enough, running 2 packs give a much flater efficiency curve (only for the first half of the run). The max efficiency level was pretty close.

The power curve also shifted a little. I don't think you can compare the results! but I guess if I consisitently use 2 packs for 8 and 9 turns then I can compare! hmmmm... strange findings! The motor also seemed to accelerater harder with 2 packs (just by the sound!) but I guess that would be normal.

well accuracy is a definite problem with the CS dyno. I think this is a way CS makes their customer happy. 2000RPM is a hugh difference.

I did two runs with the motor horizontal and 2 with the motor vertical. On both occasions the vertical positions power peaked at around 2000rpm higher than the horizontal position. It was fairly repeatable (within reason!).

Max power was around 21,xxxrpm and 23,xxxrpm resp. so 2,000rpm would put it in the 10% region.
