Well speed and the 2250 motor is mentioned, which is the truggy motor. That motor can pull some tall gearing. I ran the Plettenberg BigMaxximum which is 2300kv on the 47/28 gearing on 4s. Currently running a 1515 2700kv motor on the same gearing and 4s. I'll find a way to fit the 30T pinion on my motor mount.
I just received 2 more 4s Acepow lipos, the new 50Hz Eagletree logger, Eagletree 10hz GPS receiver for my 4s 100mph quest.

also do they only make the 47t in steel or do they have a plastic one?

do you use the stock motor mount? i have to get another gear mine is getting pretty beat. the 28 will fit with the 47 with no issue? i was running the 51/26 and that was right on the edge, but im gonna get the 47 and 28. definatley glad to rc monster goes up to 30t now
I didn't opt for a center diff and 44T spur, as I'm afraid that I will run out of torque when geared for a roll out of 2.26 and only running 4S. My diffs are allready made for a higher topspeed 44/14, compared to the buggy diffs 43/13. I could do a 40T spur, but will need to go with an 8S setup. I have allready gone the 10s A123 route once before in my GTP and want to do something different. I blew up the diffs within a few speed runs what that kinda power. The diffs lasted longer once I went to the KingHeadz diff cups and hardend ring gears.
Here is the pic of the 47T spur.
Here is the 10s A123 setup running on ipanema's.

Thanks Snellemin for the reply.
How well will the stock diff rings hold up in a 4S w/Tekin 2050-2150kv motor for road racing with 25/51 ratio? Should I invest in hardened steel rings from the get go? Are there any other weak points in the stock car?
What's the approx mph on the straight and run time with a good 5000mah lipo on a large track with a straight of ~200'? Nitro GT's can go 7 minutes on a tank and average 25 second laps and 52-55mph straight speeds?
What starting and ending RPM range should the timing be applied with the above set up and how much? Tekin ESC of course.
Thanks for your replies.

Its hard to say on how long the 5000Mah will last during a race, it all depends on how long you are on full throttle and how much you use the brake. I would take a fully charged battery and time how long it takes to cut-off, and then subtract the time before a race you use for warm-up.
I will have to answer your last question later, and I will download my setup from my Tekin, it should give you a good starting point.
