Gearing for Cat3000

[curly]

Not long ago i brought a Cat 3000. now the season has come to the end in 2wd i would like to race the cat i am going to put in a 10 single and will be racing on astroturf and tiverton.
i know they are two different types of tracks. so any help in right direction. i will be using 3300 if any help.

i would run about a 95 spur gear and a 18/17 tooth pinion. dunno what the overall ratio is though

What brand of motor is is that you are going to be using??

[burgie]

yep, the gearing suggested by carver sounds spot on. You should have wicked acceleration with that.

[MattW]

Personally i would have said that gearing was miles undergeared, but it does depend on the brand of motor - hence my question.

i normally run a 95 spear with a 19/18 pinnion.
this is on a 12x1 like. but i think carver's will be some where near.

It does depend on the motor. Like Matt said, different brands want different gearing. On Astro I run my 10x2 BRM geared on 89x23. At Tiverton there isnt any need to run a 10x1, the car will have too much acceleration for the track and you will just slide everywhere. Look at maybe an 11. On my 10x2 at Tiverton at the National I think I was on 89x25. 8)

the motor i will put in will be a 10single schumacher thamtom?? ???

It also depends what track you are on. If the track is tight, i usually go down one pinion but if its open with a long straight I would go up a pinion
