XRAY - Model racing cars

I was thinking of using 15T/48 gearing on my XT8. I got OS 28XZ which should have more than enough power and I have JP-1 pipe which is low-mid pipe. Has anyone run this type of a setup? Powerful .28 engine and 15T CB? It should calm down the bottom end, but still have enough power because of the pipe and powerful engine. Straight line speed would be insane I hope This would give a big advantage on our tracks.

DUDE! One of those O.S. 28's would be PERFECT with a 15! Those things have insane rip. The only one I've seen run, the guy couldn't get back on the throttle because it would just spin the tires. He bought it, ran it one race and gave it away because it was too much power. (And this guy drives punched out of his mind, always wanting more power........)

Haven't even broken it in yet, but I KNOW That's why I'm looking ways to make use of the power So I think I'll give it a try with the 15T CB. I searched the forum and guys have tried 15T but with .21 and not so great success...

Hi guy's first post here. lauri I have an OS 28 in my XT8 and I run a 15T clutchbell with no problems. I also run the extra head shim and the 7mm carby restricter and I have a JP-2 pipe and this thing still has plenty of punch. The track I race on is an open track. I hope this helps. I have a race meet coming up on a tighter more technical track in about 2 weeks and I will go back to a 14T clutchbell for this track.

Hello Eric,

About time you made a post on this forum! 15 tooth bell. Hmmm... I wondered why your OS was smooth and ultra quick down the straight.

You won last club meet so I'm getting one.

Are you running the X ray bells or Team Magic?

I let the XRay community know that all 5 XT8 drivers are running the Hong Nor Super Big Bores and now the 2 Mugen drivers are running them and we are all very happy.

Dave bought my spare set to put on his new Moogen which is being track released for the second round of the 240 truggy series in Bendigo.

The truggy racing was already competitive in Melbourne - I think it just got tougher. Dave was awesome in the last round running a borrowed losi 8ight T.

Are you going next weekend? 4 X 20 min heats - it was the most enjoyable race day I've ever had.

See you Sunday.

I think you will be Happy with the 15T bell. You could go to the JP-2 pipe which will give more mid to high torque. 16T might be pushing it a bit specially if you need some punch coming out of a corner for a jump.
