yea i did notice the, kind loose fit with both stock and hd clutch bells.

hows does the robinson clutch bell, hold up with a all alum clutch setup ?

and do you use a all alum, clutch setup also on your truggy ?

They hold up great with any setup. Only need normal scuffing/sanding on the inside periodically. Myself, I use an all carbon clutch in both buggy and truggy. Fioroni turbo sliders.

the only reason why i heasnt, to trying the alum/plastic shoe setup is because the rb s5 doesnt seem to have a lot of bottom end but i think a 13 tooth clutchbell could help that.

the engine is still pretty new, though and my bottom end is kind of rich.

What pipe are you using on that RB s5? that can be the reason your not getting punch your looking for.

a dynomite 86 pipe i dont have, much money so im trying to go to cheaper route with a clutchbell to get more punch. i did hear somebody say to use the nova long pipe on the 86.

That pipe works okay with that engine, the rb pipe would be better, but there pricy, you could try a longer header, that will help the bottom. Is the track you race on a small track, technical? medium, with some long straights?

i would say its a large track with, not real long straight aways and its technical. i have enough to just clear, the jumps but i would still like a little more punch. i could lean the low end out more

if you change the header do you have to change the tune ?

Yes, but it should not be too much, what tires are you running?

What are you geared at now? I would go back to 13/50 gearing. I run that everywhere, even on the biggest tracks. Also that 086 isn't helping any with bottom end. That is a purely top end pipe. I would try an 053 or at the very least a LONG header on the 086. With any pipe change, header included, some tune changes will be needed. Shouldn't be anything major though.

im using a 50/14 gear setup, whould just using the a 13 tooth bell help more ?

i might get the long header too, i know the 86 is a top end pipe its wicked fast.

Yes 13t will help TONS with bottom end!

ok il try that than if you seen, the hobby hut layout for this year than yea i need more bottom end .

last year i could get away with using a 14 th bell there.

Instead of going to a 14 CB try a 48 spur gear. I bet that will give you a better balance of torque and speed. 50/14 = 3.57, 48/13 = 3.69, 50/13 = 3.84. The 48/13 is not quite as tall as the 50/14 but still taller than 50/13. Give it a shot.

Very true. 48/13 is a good balance of the two if you find yourself needing a bit more top end than 50/13 provides. I run OS Speed engines, so it is almost pointless to run anything other than 13/50. They really scream up top.
