OK am I the only one who's iritated by the new RB engine naming system???
 
It's DUMB to use '9' for ALL their engines, no matter the size (.12 through .28) or port count (except for the TM523 Revo engines which didn't get stuck with the new name scheme).

I can understand the WS9 being the latest version of the WS7, but the rest is stupid. 'Hobby9', 'Junior9', 'Circuit9', 'Buggy9', 'Series9', 'Racing Truggy9, 'Monster Truck9', etc..........


What was wrong with C6, WS7, S3, S5, S7, TM728, and TM928??? Makes it harder to know what yer lookin' at.

OK.....Rant done. :rolleyes:

Setup Question
 
I have a RB s7 L2G running it in a 8T, what is a good clutch setup and pipe?

RB C6
 
The C6 is a great motor i would run a JP4 if u want good power and about 10min on a 7mm carb restictor. If u lookin for something more Smoother and not so mich bottom i would go with the RB 2045;). Great all around pipe combos love it around 4 gallons i replaced the front and rear bearings for ceamics and the motor has more bottom now then before:eek:.

I would start with the stock clutch and an 053 or jp3 pipe. The pipe is really going to be determined by your driving style, the track(s) you run. Do you like smooth power or hard hitting? Are you easy on the trigger or more like a light switch? All that plays into pipe and clutch.

As far as the power I'd say hard hitting, but I am easy on the trigger right now I am using a losi 4 shoe with 2 comp and 2 alum with silver and gold springs. My driving style is some what smooth still working on that.

to get more hard hitting goto an all aluminum clutch with heavier springs. The jp3 will give you more power but less run time. an 053 may work as well. As for the pipe, I would just try different ones until I found one I like

I have had quite a few RB engines over the years, tried many different pipes also, the best performance that I have had with all the Rb engines is with the 2045 pipe, and depending on the track size you are racing on, the 192 header for the larger tracks and the 198 header for the smaller tracks. The 198 header will give you more bottom end, were as it tops out to quickly for big tracks, the 192 seems more linear, with softer bottom end and better top end.
