I'm running a 13.5T V10 in blinky and it didn't really go until I set it to 50deg of timing. Once I did that it had good punch and top end on the strait.

now i have no formula for working this out so heres what ive ended up with

the kv x 7.2v =
the lrp's rpm =21960
v10's rpm = 19872

so heres where i hope someone can help,my gearing with the lrp was 23/84 =6.94 fdr,yet this is too high for the v10
so what gearing will be a match for what i had with the lrp
im currently at 28/84 = 5.70 ,i have tried pinnions from 25 to 28 ,the 28 feels quickest
but it doesnt feel as punchy,motor timing is at 1 mark past the 30deg and doesnt have the same top speed yet the motor sounds like its reaching peak rpm at the end of the straight ,temps are coming off at around 60c
im using an orion r10 pro with max punch and boost at 32 and turbo 34
Is this an indoor track you are running on?

Anyone got a setup for 13.5 boosted using the hobbywing 3.1 esc using the v10 indoors on carpet, tight track in TC?
Thanks in advance!

id normally agree but the gm runs at 5.70 some team drivers quoted using 5.50 and the v10 feels very much like the gm,ie torque instead of rpm,5.50 was overgeared so went back 1 tooth to 5.70 and its got more punch out of the corners than a gm and a x20 that i ran against today,the x20 would start to catch up towards the end of the straight but my infield speed was faster and with better brakes than the other 2 and i posted the fastest lap,track was low to med grip due to pollen falling from the connifers,i had a dusty car after every run so getting a 14.7 on old tyres i used at the wlrc clubmans wasnt to bad with the track temps reaching 48c ,my fastest lap is a 14.2 at amcc
but that was on 28's when it was colder
we had a speed gun today and the x20 hits 51mph at the end of the straight im hitting 48/49 but over the line in the midfield i was hitting 36/37 where the x20 was hitting only 33/34

my motor was coming off at 80/85c
as you know it was a tad warm today so overall im pleased with it,well until matt q and some of the other fast drivers return and show me that ive got it all wrong,lol

i had the motor at the 30 mark (factory setting) boost 30 turbo 40 on an orion r10 pro 2/3 s 28/84
i was told my car had the fastest acceleration out of the three of us onto the straight,so it could be that the x20 was slightly over geared


now ive had a bit of time to think about it,i ran a 29t pinion in practice when i had 33degrees motor timing,if i had dropped back to the 30 mark it would have a touch more torque to top out at the end of the straight,so i might have another try with the 5.50

any info you can throw at this will be apreciated

I don't know anyone gearing as high as that. I have ran quite a few different motors over the last two, three years, I used roughly the same gearing on all of them

see for yourself,it looked quick enough to me, when i ran this motor at 6.1 it would brake when off throttle and i mean like i applied them so felt it was revving too high at the end of the straight,in the vid the orange car is my son with the gm,he has the same gearing as me and he is still undergeared,im putting his to 5.50 for the next meeting

Not raced at Aldershot for many many years, looks similar size to Bedworth I would say, I run 6.23 on my GM at Bedworth. Hard to tell from the video, he seems to be struggling a bit on acceleration and top end compared to the others.

its a longer straight than at bedworth,havent been there myself,its probably double the length of wlrc's straight,barrier to barrier.
ill try adding some more turbo before the gearing change
i should have said the white car had the x20 i was the purple/blue car

I can probably sort you out a v3.1 setup if you want, and the highest I would gear would probably be around 5.9 for somewhere like the Cotswolds track

So what's a good ballpark starting setting and regular operating temps for 13.5t boosted TC outdoors, endbell timing, fdr, boost, turbo etc for a track with a 30m straight.

i ran mine with 32 end bell timing 30 boost and 39 turbo,(they need a lot of boost/turbo) and 6.9 fdr
temps were around 85c on a hot day
this was info i got from a team driver at wlrc

Top man, thank you. So gearing is in the middle then, it's not super torquey and needing a low fdr and not a rpm screamer needing a high fdr either.
