Dont get me wrong, i dont even know that particular speedo! What i meant was that u should be carefull since it has history...

Also, try to be carefull when u ran a motor close to ure speedo limit. Gearing is crucial, and prolly the most important factor, but pay atention to ure drive train. Dirt, hair carpet and other stuf get into ure car and make life hard on motor and speedo.

Ah, and gear mesh to close can also overheat the engine.

In doubt the old thumb rule (get ure finger in the motor after running. if u cant keep it there for 5 sec, reduce ure pinion) still works.

Good luck with ure new engine!
you mean motor right?

What are you going to do with the car?Race or play?Either way gear it so the motor doesn't get too hot.If you can temp it with a temp gun keep it around 160-180 farenheit.To make sure your not burning the motor up check it periodicly during a battery pack about 4 or 5 times to make sure it's not.Once you get the gearing right then check it after each run.The more free the car is the bigger the pinion you can run.If the car is too tight meaning not free or something is binding the rotation of the drive train up then the smaller the pinion you will have to run.I only race my car and the track I race on is 100-120ft in length and 50-60ft in width.I normally run a final drive ratio of 6.49 with an EA Motorsports monster based stock motor.My tires are RP36's premounts and I run on asphalt.My motor temp stays within 160-180.

i know my gearing is pushing it...i use the stock gearing with a 17t double quad magnet and damn does that thing get hot, but it doesnt get tooooo hot its still reasonable. i have a final ratio of like 6.42 i believe, but damn does this thing pull off the corners =)

Sorry I didn't give you the equation.

Spur divided by pinion times internal ratio of your car

example My spur is 84 my pinion is 22 my internal dive ratio is 1.7
so 84/22=3.818x1.7=6.49

My motors stay around 160-180 for the track we race on.

What car do you have?I run an XRAY FK05 it has a stock ratio of 1.7.My T1R has a stock ratio of 2.125.your internal ratio is the eternal ratio of yout transmission or for like the XRAY's it's the diff gear divided by the layshaft gears.I don't know what the other ratios are for other cars but you could look on here in other forums that discuss different makers and post in there for the ratios.
No it doesn't tell you what ratio to run on the motors.I would ask at your local track or local hobby store for recommended ratios.

I don't recall if you were going to race or just play with the car.But I have not run any of those motors.I currently now run EA Motorsports monster based motors and batteries.I am still fairly new to racing so I don't have alot of experience with all the different motors.EA Motorsports has in my opinion excellent service and turn around on thier product and questions concerning thier product.Not to mention these are the best motors to date that I have ever run.So it's up to what your doing.Just playing I'd say yes racing I'm not sure.
