Hi Guys

Can anyone advise me a FDR for a medium sized track? im running rubbers as well

i ran comfortably at 5.3 : 1 FDR with the original rotor in my 13.5.

Or how many teeth did you guys go up in pinions when swtiching to the sintered rotor from the original rotor?

cheers in advance

We run on a 75x40, and are running a 4.6 final drive. That is with rubber tires .

Sorry, your question was not answered. The GTB/SS Pro systems will begin shipping next week. All Pro systems feature motors upgraded with the sintered rotors, ribbed end bells and oversized bearing.

I started at 4.5 : 1 FDR and went right down to 4.17 and had a temp reading of 167 F i believe in race conditions i would end up a little higher up to 180 F, Also Ambient tempreture was only 21 deg Celcius going by last nights forecast.

I must say im back to the stock brushed feel / handling! due to the extra magnetic feel of the sintered rotor. But in all honesty it feels strong at the start but i sense the speed drops half way throughout the run like a brushed motor, possibily heat fade on the sintered rotor?

BrainTeased - I am pretty sure you are over geared. Forget about temprature. We are not talking nitro motors here so temperature is not an indicator of correct gearing. The correct gear ratio is what gets you the fastest 5 min run no matter the temps. In your case I think the correct gear ratio will make your motor run cooler than where you are now.

Most guys gear this motor in the 5.25 (small tight tracks) to 4.5 (huge outdoor tracks) range depending on the track. There is a point where you gear up and you get slower. Really good drivers can feel it. The rest of us can easily see it in our lap times.

The sintered rotor is safe to run over 200* F. Most racers will never get anywhere near that unless that are running out doors in 100*+ weather.

Thanks for the input Adrian!

I got the sintered rotor just last week and tested it out on a non race day so i had no lap times to see how it was doing so with the orginal rotor we were all gearing according to temps and performance. So i thought naturally that we'd do the same for sintered rotors

but i agree the motor did feel over geared i even thought that my batteries were getting old!!! as half way i felt a noticable performance drop esspecially in the bottom end.

Now with lap times, do sintered rotors give any advantage? To be honest althought it does seem slightly faster on the top end. But not being able to do a back to back run with the orginal and sintered rotor, its very hard to tell essepeically without lap times. I will be reporting my test results after this sundays club meet.

The sintered rotor is faster. It will let you run a bigger gear and tap into the motors full potential. The bonded rotor gets hotter faster and limits the power of the motor. The problem with the bonded rotor is that you can get it hot enough to shut down the speedo due to motor heat and this can be very inconsistant driver to driver.

A smooth driver with lots of fans will shut down a bonded 13.5 later than a on/off throttle driver with no cooling. The sintered rotor make racing easier becuase you have one less thing to worry about.

I got mine in the mail today (it was a birthday present) and I am very impressed with it. I have never really had a stock motor (I usually race mod) that is even worth using but since I will be racing at a place that only runs stock I thought I would ask for one for my birthday and this thing is much faster then my other stocker. It had great torque and and plenty of topspeed I have no way of comparing it to a worthy stock motor though so I dont' really know how much faster it really is. This was just up and down my street so I can't wait to get to the track and actually test it out....

One step closer to the tunned brushed motor....closer, but still faster I think...(EX-13.5, check out the wattage output...)

Hi guys

Got some good news! sintered rotor really does tap the motor into its full potential! (geared at 4.67 FDR running temp of 140 F ) i've managed to beat my best lap time by 0.3 of a second and get right behind and sometimes in front of the race leader who wins every round week after week! unfortunately due to some really bad luck in the finals i didnt get a fair chance to run with the best guy in stock today. Bring on next meeting!
