Well i just got a new 48t metal spur just recently and was wanting to run it what pinion should i use for the same ratio as the 15/45? Thanks for all your help.

i an not to sure but try the 10??? or 12???? i never had a 48 on my buggy???? are u able to get a 44,45, spur?? and r u near tn??

I have a 48t metal gear on mine (not by choice, in a pintch) but I had to shim out my center diff to fit the gear on the 8ight b e. I just had to put a small piece of material ( I used g10) under both half center diff holders. Otherwise the gear would not work.

Tonnes.


I highly suggest you pick up a 45T Metal spur, Ratio's are outta wack with a 48T, Not to mention having to shim up the Diff to even make it work.

runnng 45tspur 16t pinion, is a blast

what are some good hop-ups for a losi 8ight te,

After running a vorza with tekno conversion for 1.5years, then drivng this 8ight t, FEELS SO MUCH BETTER

i had a good weekend but full of pain, i geared mine buggy 16/45, the temps was high, still did good, i used the green ft springs 40wt oil and green in the rear 27.5wt oil. handled ok still didnt feel just right?? i just need something different??

Were you running the 1700 or 1900?

If you were running the 1700, 16/45 sounds slightly undergeared.

yes 1700kv tekin? u think i need a 17 tooth??

Yup. I find that you want 1 pinion tooth for each 100Kv you go down on motor. Also, I have been told that for every 2 teeth on a spur you also want to go up 1 pinion tooth. This I learned from a veteran on-road guy it may apply better to finer pitched gears but he also races EP buggy now and says the ratio still works well . . .

i have a 2250kv so i should be at a 22 mod 1 pinion? I'm currently at 15t and its a nice run....could i go up that high!!

I would step up the rear to blacks.
Another thing I'm thinking is stepping up 2.5wt both f/r but don't know the temps in your area this weekend and would be more based on that (65-80).
At 60* and below I would use your oil rates and 90* and above I would step it up 5wt for f/r

Oh no! You need to subtract from the pinion if you are going up on motor. For you I would have a 12 & 13t on hand if you are running a 45T spur . . .

ok ill run with a 12 and 13 this week and see how she feels

Well if you are happy with your setup I would not mess with it! I am sure it is pretty hot in Florida already and if you have the speed you need and temps are fine then just let it ride . . .

agreed, but i want to check times and temps so I'm going to run 12,13,14,15 and see what runs best (2250kv motor)
