E4RS has its own limited gearing bracket, for 64P, your T on pinion and spur combine should be between 140-150T...for 48P, my guess (I am not sure) should be between 110-120T. (again, other can varify this).
So, to get up to 5.5 final drive, you should try 84T spur with 31T pinion with internal drive = 2.0588 (84/31 x 2.0588) = 5.57
I am only showing you what you are asking (5.5 final drive)...if you are running TEKIN with V200 or even V203 software, I really think 5.5 final drive will SMOKE your motor in no time.....please verify the right final drive to use for 200 foot track, outdoor with TEKIN and tekin owners that use 200 or 203 software....but the gearing can be done on E4RS. You just have to stock alot of spur and pinion.

Seriously....13.5 @ 210 feet long straight..? Isn't that kinda boring to watch/race? You need 6.5T motor...LOL

Thanks for the info ...
No boring to watch, its a big track and we change layout every 2 races, so on the first of the year this weekend, we will use full back straight.
Already contacted tekin team manager, recommended me to start with 5.2 and try up to 5.8 on 203 software.
Problem is try to get the spurs here, if i dont get them i will not race, prefer to pass than smoke motor lol

I don't own any TEKIN, but I heard what they say when they compare final drive...I heard 9.0, 8.0, and alot of 7.0 when we were racing outdoor larger track (not as large as yours).
I would definitely start @ 6.0 and gearing up...you always go undergear 1st, then compare motor temp and lap time...you can always gear up, but you might not be able to gear down when you see smoke coming out from your electric car....

When i used to race Novak, my temps were always 160°F or so, and 3,6 FDR on that track when using full back straight.
Here in Chile to buy pinion and spurs i have to order from USA, and with all christmas stuff i forgot to do it so maybe i will pass first race,

I am not sure 64P help you or not...I have never use 48P spur and I do race OUTDOOR parking lot that have plenty of rock and dust...I have not strip any spur gear for the last 4 years of racing with my TC.
Modified motor might be different............

How long is your straight then??
cheers Roy

Hehehe Solara I blame you for me hating my JRX now ROFL.
I am able to dive into the turn at much higher speeds now and keep the speed inside a turn.
It has less steering but the harder i push it into the turn makes up for my angle i guess.
Dont get me wrong i love the MMP its like on steriods.
I had it sit on the side and have the Fan hanging off.
It runs great but at this time I really dont want to damage it when getting T-boned.
Our track has a Loong Straight
It has been changes out abit, it has more turns before the straight away now.
Lower right and Left of the pics have few S turns now.

I like the gearing of what i have atm 5.9FDR with a 6.5t
Any recomendations for a 13.5t ?

Oh no...please don't say that the Tekin RS is almost the same as the GTB...
I can tell you from all the ppl that raced around me who used Tekin RS (like 100 of them...LOL) Racing 13.5...at some very small track, they were using the old software V200...were using final drive as high as 9.0 (YES...it is not typo, 9.0 final drive). For alittle bit bigger track, average wer 6.5 to 7. So...I think your gearing was WAY too tall....lower your pinion, raise your spur and keep playing with the timing and turbo.
I know the last time we raced outdoor with a 125 foot long straight, they were all using 6.8-7.2 final drive with the V200 software...
Now....here is the kicker, they just released the V203 and that is some INSANE software for 13.5....there were track and event already banning this software due to the "SPEED"....and from what I was told, ppl using the V203, with 13.5 motor, were gearing @ 7 and higher...
To sums it up...your gearing were too tall.

Our outdoor track has a straight of about 130 feet.
With the LRP SPX Stock spec and the 10.5 GM motor we gear it about 4.27 to 4.6 FDR
I use the GM esc with the GM pro stock 10.5 and have to gear it about 4.6 to 4.8 FDR.
This was with 5 cells.
The guys with 13.5 and lipo gear about the same and gain on us on top speed.
We had 1 Tekin driver there with the RS pro esc and the redline motor who geared a lot lower,about 5.2 to 5.5 and he still was faster then all of us driving the LRP motors and or the GM motors.
The Tekin was screaming on the straight it was just awesome to see and hear.
So for a good FDR you have to start with maybe a to slow top speed and work your way there.
Better start slow then fry your motor or ESC.

Can you explain why the gearing is so drastically different on the Tekin vs. a Novak. I thought all BL are pretty much the same with the same range of gearing but from what you said, that LOW 9.0 FDR sounds more like the old days with brushed Epic 27 turn motors. I'm used to gearing my BL 17.5 around 3.7 -4.0 and my 13.5 around 4.0 - 4.5. I'm running a Xcelorin 17.5 now at about 3.7 FDR. I just can't imagine 6.0 or 7.0 FDR on a 17.5 BL.
GTB has no timing adjustable...all rely on the motor's timing if there is one.
Tekin, LRP, Mamba, Speed Passion, AE Black Diamond from the last 2 years...all has build in speedo adjustable timing ON TOP of the motor's adjustable timing. Tekin, even has the TURBO MODE along with MMP's Cheat Mode to BOOST the motor on the straight for a short period of time.
2 years ago was the MOTOR of the month...the past year, was the Speedo (software) of the month...this year, who know...may be only SOFTWARE/FIRMWARE of the month.
With all these new software/techology behind the speedo, the good old 4.5 final drive for typical 13.5 motor will only get your motor blew within 1 minute. Of course, unless you are still using GTB that is.

If i can drive better LOL i could get all the power of my MMP to the ground LOL
But my driving is intermediate at best LOL
With boost on and timing all jacked up to crazy numbers a 10.5 can easily keep up with a 7700kv motor, car makes a funny wierd noise but yeah ....
