I've done some research and found out that on the 008, the internal gearing is 1.7 or 1.9..

That would mean that the math would look something like this (if in fact the internal gearing ratio is 1.7):

Spur/Pinion * internal gear ratio = 3.500

Spur/Pinion * 1.7 = 3.500

Spur/Pinion = 3.500/1.7

Spur/Pinion = 2.058

Spur/2.058 = Pinion

84/2.058 = 40.8...


How big a pinion could I actually fit in the '008?
Would it make sense to go smaller pinion and spur?

Appreciate the offer, but for starters feel free to try and answer in this thread ;-).

Counted the teeth on my pulley set and I'm actually running the old original pulley set, the 38/16 set, so running with an internal ratio of 2.375 :-(..

This still doesn't change the fact that I would love to know the biggest pinion that I'll be able to fit in the car with the 84 teeth, 48pitch pulley that I've got on there.

I'm also looking for a great EU vendor who sells spurs and pinions for the T2'008.

I'm also looking for a place that sells the replacement pulley set for the T2'008 which alters the ratio to (34/20) 1.7.

Hoping someone here can help me out with some of my questions.

Counted the teeth on my pulley set and I'm actually running the old original pulley set, the 38/16 set, so running with an internal ratio of 2.375 :-(..The 08 came with two internal ratios, 1.7 & 2.375...forget the 2.375 & use the 1.7

This still doesn't change the fact that I would love to know the biggest pinion that I'll be able to fit in the car with the 84 teeth, 48pitch pulley that I've got on there.the pinion size will depend on the spur size of course...it would be helpful to know what motor & ESC you're running, THEN, can give you a starting point

I'm also looking for a great EU vendor who sells spurs and pinions for the T2'008.A Main or Stormer Hobbies

I'm also looking for a place that sells the replacement pulley set for the T2'008 which alters the ratio to (34/20) 1.7. Again, A Main or Stormer Hobbies

Hoping someone here can help me out with some of my questions.
Job done

Hey Brokin, really appreciate it.

I bought the car used, so I'm stuck with the 2.375 ratio.

I'm running a Robitronic 13.5 turn motor with an Exelorin ESC.

I'm aiming for an FDR of 3.500, 'cause thats the limit in the Super Stock Class here in Denmark.

If you go to gearchart.com you'll be able to imput you data & find fdr, rollouts etc & print them out for later....Or if you're at the track you can use this formula

Spur divided by pinion multiplied by internal ratio which gives you FDR, then divide this figure into 197.8 & that will give you your rollout (within a pooftenth)

Try & balance spur/pinion sizes so that you're pinion isn't too big

The aluminum steering blocks use a 3 x 5 x 9mm bearing. If yours is loose then you must not be using the the composite sleeve that the bearing presses into.

I don't have the composite sleeve.. I guess the right size could be 11x5x4 because even the 10x5x4 is lose...

please correct me if i am wrong

I doubt you will find a bearing that fits properly without the sleeve, they ARE NOT designed to run without the sleeve. Spend the $5.00, buy the sleeve set and do it correctly. Bearings last forever with the sleeves also, as they help to absorb shock from impact.

the xray branded type use 11x5x4. not sure if the epic knockoffs use the same geometry, but i would feel confident to bet on it.

i'm a big fan of purposely omitting the plastic bushings in favor of a more robust (larger) bearing. the 5x9's blow out if you look at them wrong.

I'll have to disagree with that. Running the stock bearings in mod on all 4 corners for a few seasons and I saw no abnormal wear or bearing issues, and the composite sleeves do help defer the bearing shock. To each his own.
