Then we will need a dyno at each event that produces the same readings as the one used by PN or whatever manufacturer is making the motors so we have readings that are consistent. That is something that can be done but it is cumbersome. PN is saying in their testing that their motor goes x rpm's with a variable of y. If TB motors produces a motor for stock racing that is 21000 rpm with a variation of 3350rpm is that ok. If it is a 3351 variation then it is disqualified that is tough and perhaps not the fault of the person entering the race. I guess then that person would not race TB motors any more?

It would not be a dq on pre tech....as you said motors are cheap... i carry 4-6 motors with me at all times....it is east to open a 130 motor can and leave no marking what so ever upon re assembly there for the need for a specification to go by....it could be as simple as having a motor checker and a baseline sealed in a bag motor from each manufacturer to use as your base line then adding the variation +/- and if the motor has not been tampered with it should fall within the variance supplied by the manufacturer

OK just a few more items on the motor issue. Do you have any concerns about timing and we should only allow single stack armatures for stock motors.

As far as technical inspection goes with respect to a benchmark for a specific motor with a degree of variance being motorchecked at a track I guess that is the best way to go but in the future we need to get motors that you can't jack with in stock and if they were rebuildable, I guess that would be easier to tech out and get the rule benders.

i do not know what a single stack armature is...... and i believe that timing will affect the rpm ...so long as it will stay in the limit
as for the future....with all respect for the guys who drive 70t cars to its full potential i believe that in the stock class there needs to be equality....
the fast guys will always be the fast guys if it isto become a mod 70t class nothing will change....the fast guys will still be the fast guys.....even if there motors were slowr that the rest......it would only make it easier for the fast guys to be flawless.....70t is 70t....theh reason for the 70 t class is to try and separate the 2.....rt now @ my track the fast 70 t lap record is within 6 tenths of my mod pancar lap record....i actually think that we need a 90 t stock class motor and a gearing limit.....lol
j/k lukas....hehehe inside joke

I know fast guys will drive almost anything faster....
the fast guy at your track did he prep his 70t or just toss one in straight from the package???

I had seen similar comments in ROAR and other ruling bodies rules. I don't think it is a worry in our class and if it is ROAR will let us know when they look at this stuff.

Yasuji, here is the KyoshoUSA response to my questions about details on there stock motor. Maybe an inquiry from you would get a better response.

Unfortunately we don't have any supper detailed info on our mini z stock
motors, but yes they are maid and comparable to Mabuchi motors.
