Most of us that run a 1900kv use a 16 tooth pinion. I think the kit included 14 tooth would be under geared quite a bit. Even with a 2050kv i would think a 16 tooth pinion is the right starting point.

Nobody has any setup help for smooth med/high bite clay? Just looking for piston, spring, and oil combos

Just got back from running at revelation raceway. I'm still cooking this motor with a 15t at night and diffs at 5k 50k 2k and body with more cut outs than needed. Lowest was 188 and high of 220. I run it hard, tires ballon, heavy throttle heavy break. I have stock out of box settings for esc and 2050kv. Any suggestions besides a fan that will just break. Help!

First of all, why in the hell are you running 50k in the center???? Does the esc have any timing at all or turbo boost??? Is your motor a tekin? Dude 774 on the diffs!!! Most important tho, make sure you have no timing on the esc...get rid of that 50k..ebuggy needs no help with going fast,that 50k is putting way more power to the ground Han needed...also, you could be over driving it,rev can be loose if you driving out of the groove, wich equals way more wheel spin

Stock setup, just run the car lower like 24mm..stock 8h pistons and springs,heavier oil, tlr 45f/40r..if you need it to rotate faster, remove the sway bars,helps with more steering and rear traction....

Is all 4 tires ballooning ?, is it one tire in a turn (diff out)?, just the front? I tune my diffs for the available grip of the track, but balance them out against the ballooning of the tires. You could turn your current limited down (punch)and go thicker front and rear. With 50 in your center. Front and rear are getting power. You could try to smooth it out. Ballooning the tires is just breaking traction and working that motor at max RPM. You could try to gear up so your not always spinning her at max. With of watching your buggy run, these are just things to look at. No binding in the drive line or motor? Do you have the SMC 1900 by chance?

Is that 24mm front and rear or just 24mm in the back?

I run 100k in my d413 and thought I'd try the 50k to see if I like it and I do but I'll go back down 774. Yes it's tekin and it's stock set up but I'll reset it to make sure. I am over driving it but in the groove 80% of the track. Last night track real dusty.

just the fronts Balloon I think it's because of the under drive the rear that it's just front. No binding at all, mesh pefect, and car in perfect condition. It's a tekin 2050kv. Tekin esc. I can Balloon the fronts on demand or not . There's the spot on the throttle when it just happens. 75 to 80 percentage full they Balloon. I wanna run as fast as I want with out cooking my motor. Also when I ran the 17t gear the front tires balloon more and wheel spun was worse. 15t car was easier to drive less wheel spin and balloon. Go stock 14t?

What about dropping down to a 13 or 14 tooth pinion?

Imo running the underdrive and 50k in the center is putting the drivetrain in constant bind. Like the guys said go to 7/7/5 or 7/10/5. I run a 15 or 16 pinion with a 1900 smc and it's plenty fast with the 16. For a 2050 I would try a 14 pinion.

Try backing down your ESC's current limiter. You'll be surprised at how far you can dial it back without noticing a performance change. I've run mine as low as 65%. Helps with the amperage spikes that can drive motor heat. Same with brakes..

All those ideas are great. I'll back down to 7 in center, 14t gear and turn esc down just before I notice a loss. I gotta say that 50k center is fun. You can be at a face of jump just rolling for double and just a blip and it's launching. I'm really thinking it's all about traction and no wheel spin. Investing more time and money in tires.
Also my Temps were higher when I was driving to Metallica, does Metallica cause higher temps?

Just think of this,when Drew moller ran for mugen, he ran 5k in the center.. There is a method to running ebuggy fast, and that's toning everything down.. We don't run anything over 7k in the center. We use to run 10k, but drew's dad said it makes ebuggy too erratic,and it was true,it toned down my sons driving and made him way faster..my son runs smc 1900 and speed passion esc..next Thursday we will be at rev breaking in a motor... Come talk to us, ask for Steve Harris mugen team guys..
