This is strictly off-road racing conditions (no top speed runs, etc.). Once going to the 17, I have not changed it. Much like the 19 tooth pinion was standard on my .3.

In addition to Joe's question, will heat be a non-issue with a 1900kv motor and proper gearing? I'm getting back into the game after a few years off and I've never run ebuggy, so I'm not quite sure what to expect in terms of electronics abuse. I know I can run my stock B6D all day long without any worry as long as it's geared correctly. But I also know - at least as of a few years ago - ebuggy and Pro4 SCT was a bit like Russian roulette electronics-wise. I recall seeing more than one rig go up in smoke just because.
edit - looks like vwduud hit reply when I did, and answered my question in the process

I ran a 17t without issues at Motorama with a Tekin gen 2 1900kv. I would guess 16t-17t be good to cover you at 90% of the tracks

If I HAD to choose savox (Which I don't run any) I would roll with the 2274 with 7.4v. It meets your budget, and gets into better specs when run at 7.4v

My first Savox was purchased as a result of having a 2 week old Futaba servo failed at a big race event. I think it was the 9351 at $129 - $149. I don't see that servo listed anymore. In fact, at the time, I had even paid an additional $50 to $75 to upgrade the plastic case to the aluminum case. Making this 2nd replacement servo well over a $200 servo. The aluminum case upgrade was suggested after my first 9351 failed and had to be replaced. Was trying to make the servo last longer. It lasted 2 weeks, until it began exhibiting the same problem: servo would shake and quiver at the neutral position.
I'm surprised that ANY servo can survive the abuse that a 1/8th vehicle throws at it. Think about doing upwards of 40mph down the straight away in an 8 to 10 pound vehicle and turn into the sweeper too soon, snagging the inside wheel on the pipe. With or without a servo saver, the servo now gets "yanked" in a very abusive manner.
I had already seen where buying a more expensive servo did not guarantee longevity. My first Savox purchase was a result of being my only choice (the hobby vendor at the track ONLY had Savox servos to sell). I think it was the 1256 or 1258. Again, all he had to sell me. That servo lasted me over a year. I only retired it because of the specs of the 2274 and I was building a new buggy.
Servos and chargers, to me are considered "disposable". I buy what does NOT inhibit my performance, by sacrificing specs by pinching pennies. But I do buy the cheapest that will get the job done. When it fails, it hurts less. If in warranty, I might send it back for repair or replacement. If not, throw it in the garbage and replace it with a new one (same make and model).
Funny thing is that I have almost 2 years on my 2274, across 3 different buggies (EB48.2, EB48.3, EB48.4). My cheap $50 power supply and $50 charger have outlasted all of my previous "expensive" chargers (Hyperion, etc.).
The Savox 2274 and 2273 servos, at under $100 a piece, have served me well in my eBuggy and eTruggy. They have the specs (speed and torque) needed to make either of these racing vehicles race worthy. All with the surprise benefit of long lasting, yet, when they fail, not as disappointing as when my $200+ servos failed.
