So when i'm looking for a really good Spec motor I need to look at the AMPS not the turns or KV..


I was checking out this motor Schuur Speed Spec Class Motor

vs

"BULLET" 13.5 SCHUURSPEED

This is the "Bullet" version SchuurSpeed V3 13.5 Motor, tuned for ROAR Approved Stock Racing. Comes Standard with 12.5 mm Rotor. All motors will include all Stator Resistance , Coil Inductance, Rotor Gauss Readings as well as the Dyno Results.

Ryan Rudy from bullet-motorworks does he take the motors apart and fit them to what you need.



I'm asking b.c. I want a good one for my OVAL Street Stock.


Anyone have more info about BRUSHLESS MOTORS.

Do I want a high amp pull or a low amp pull motor?

Thanx M

There's a lot going on here. What exactly are you looking for?

Sir I want a good powerful fast motor for Oval

Its B4.1 81 spur to 26-31 pinion.

Spec class 13.5t

So what do I look for in a motor? amps from what I read.

I was thinking kv, but its not true.

13.5t that pulls more Amps or Less Amps to be powerful and fast?

Thanx sir

You'd want a motor that maximizes output power and efficiency. That's what we all want. Since the motor mfgs don't give us load data, people will test motors on their dynos and/or analyzers or test them on the track. Word of mouth spreads pretty quick on what's a hot motor. I'm not sure the ideal motor for dirt oval. Particularly, I don't know if a low, mid, or high torque rotor would be best suited. This may not be satisfying advice, but you may want to ask at the track for a clue or try the Oval section of this forum.

Maybe someone else has a more complete response...

You cannot just look at KV or number of turns in a motor. The size of the rotor in both diameter and length gives you different power schemes. So let's say for one motor model, e.g Novak ballistic 540 can size:
1. Lower turns yields more power (more amps = more wattage)
2. Higher KV yields more power (more amps = more wattage)

Bigger motor cans, e.g. 550 will give you more power obviously.

Normally motors are either defined as modified (typically in the range 2.5T to 9.5T) or spec/stock (typical range 17.5T-25.5T). In modified racing you can alter the rotor within the same can size, but in spec mode you cannot alter the rotor size (a classic cheat). However, some motors are better than other due to better cooling, bearings, efficiency, etc.

If you are limited to 13.5 stock, there should not be much difference in power between the top motor manufactures. I hope that helps.

In both stock and mod you can generally change out rotors within the parameters of the rules. Check your track's rules.
