Anyone have trouble upgrading to the 20t alumninum pully? It made my belts super tight and i couldn't screw in the top chassis so i have up.

How many teeth in the stock pulley?

Just wondering are there any metal or aluminium outdrives for the front spool?

This was a problem with the Zero S, which had a 38T diff to a 20T pulley. People got around this by either going to a 37T diff or a 19T pulley.

Because the Xi Sport uses essentially the same drivetrain, the 19T pulley became standard to prevent this issue. Plus it gives an internal ratio of 2.0, which seems to be ideal with current motors.

Interesting...so why does the Sakura Ultimate 2014 have a 20t pulley. I hope i didn't jus waste my money.

It has a 20T pulley because it has a 40T diff.

Overall internal ratio is still 2.0.

So i basically wasted my money hahaha

Is the stock asphalt setup any good for low grip USGT and VTA? I have a set of sway bars and sakura springs too. Need to get it on the track quickly, and looking for a good baseline.

So far, I've built the diff, and put associated 1k oil in the rear instead of the kit supplied oil, but that's it. The setup sheets I've seen for the XI vary a lot, and I'm not experienced enough to come up with a plan for this build other than something instructed via a setup sheet, or the manual.

7k weight oil in the rear diff? That seems high, but maybe not with the wider rear tires. I thought that was a carpet setup from one of the tracks in Oshkosk, Wisconsin but maybe they race in the "HT" (HobbyTown) parking lot there, too, as indicated by the "HT Oshkosh" description on the setup sheet.

It's my setup for carpet, HOWEVER I used this same setup for asphalt racing during summer, change for the gear ratios since the outdoor track is usually a bit larger than our carpet track. But I run 7k diff oil and have no leaks and a nice smooth rear diff

Awesome!! Thanks!!

Alright so the fast guys on my local carpet track are running 10.0 second laps.
The 1st time I went, I was at 15, the second, 12.6, the 3rd(today and got a good radio) 10.9.
The guys are all telling my that at this rate, I need to get myself a descent car (X-ray, Tamiya or whatever) They even say that they could really tell the difference with a Sakura Ultimate?
I had many setup problems but mostly my car kept rolling over at very high speed.

I like the car so far but am wondering how competitive one can get with it?
They all say X-ray VS Sakura is like night and day?????????
What about the Ultimate, can you really feel the diif with X-ray?

I got told the same thing HAHA! I know the xi sport can keep up with the fast guys with practice, driving skills and a good set up. Upgrading to a alluminum steering, stabilizer kit, front cvds and floating servo help alot. Personally i'm about to get a ultimate and use the xi sport for usgt.
