is there any performance diference between 48 and 64 pitch???

Yorkie

64 pitch gears are supposed to be more efficient due to less friction loss but they are harder to set gear mesh cottectly and are easier to break of they come in contact with debris from the track such as small stones.
They are alot quieter also.

I've ran 48 & 64 pitch gears and I prefer the 64's just for being quiet but for performance I can see any real advantage.

All the hot drivers use 48 pitch anyway...

Setting the gear mesh with 64 pitch is a B!TCH. That crappy little paper trick dosn't work very well. LOL

48 Pitch : More Torque, very durable, adjusting gear mesh is very easy, but noisy and less efifcient
64 Pitch : Less Friction, more hi-end speed, more efficient, quiet but durability and gear mesh are &%#$@

Why would 48 pitch give more torque?

Speedo

There is no advantage performance-wise, though it may feel that way with 64 pitch because it is quieter. 64 pitch is quieter and can be smoother. Or if you want a balance, get 56 pitch

64p allows for finer gearing adjustments giving the racer that slightly better edge than next guy who doesnt have it.

you can move the final drive by increments smaller than one can with 48p gears, providing themotor with the best possible rollout.

the down side though is that they are not as hardy as 48p.

if you race in a club full of serious racers, where every millesecond counts, where each little bit helps (like rebuilding your bearings every weekend) GO FOR IT!

if not, 48p will give you better reliability.

torque and speed have nothin to do with Pitch.

I switched my TC3 to 64 pitch and noticed that it is a lot quieter than the other TC3's on the track.

As far as the mesh goes, I dont ever seem to have a problem with it, maybe you guys are just impatient. It's a little harder than 48p, but if you take your time its not that hard.

i was told that gearing a 48 and 64 are different . are they the same ratio when gearing

benraldo the ho

Well they are diferent in that 64 pitch gears have more teeth on them.

For example.

27/72 48p is a 6.67 gear ratio {in a tC3}

you can get the same gear ratio by doing

36/96 64p

So the ratio is the same, but the gears have different amounts of teeth.

LOL I've sat there for ages trying to get it, maybe I'm just a retard.

Nope, getting proper gear mesh in the TC3 with 64p gears is a pain in the a$$, but, when you get accustomed to do is very simple.

Little trick, the piece of paper works for 48p, but, for 64p gears, you need to get some more thinner, like some clear plastic used by your mom to wrap the foods on the fridge.

What size 64 pitch spur gear would you guys recommend for a TC3 (friend's car). Keep in my mind he only races stock. Thanks in advance.

Corse-R

As a ballpark, grab a spur between 93 and 98 tooth, (93 or 95 are ok, 98 tooth, for modified is ok).
