Well I ran the Rally10 for a few tanks in my practice car this weekend and WOW!!! The Rally is not going to make a very good buggy engine as the power delivery is INSTANT and insane... tires turned into pizza cutter out of every corner and and just sounded angry!!! I did run the 2018 pipe on the engine so maybe a 2045 will tame it down a bit but I am thinking this might be a better truggy alternative.

I have never tried to run this engine in a truggy as I feel it would be under powered in a truggy. I do run a Losi truggy so the main thing I can suggest is you run 13/50 gearing. Also a lot depends on the pipe and header you are using. With an S5 in truck your going to need a long header and possibly the 2020 pipe to get that extra grunt you are looking for. Also I know in my 8ight 2.0 truggy I run all aluminum shoes with all gold springs when I need the extra snap, you can try to silver and two golds too, or even all 4 silver.. the shoes will wear faster with all silver but it will really spool up before engaging.
ok thanks im using a 13/50 gearing, it does have extra punch but not quite im using a dynamite 86 pipe, so i could ethier try the all gold spring setup or a longer header.
the engine is on its second gallon.
what would make the, biggest diffrence a longer header or stiffer clutch springs ?

Honestly, a different pipe will help more than the header or the springs. The 086 pipe is a top end pipe so nothing you do is going to help a lot. 90% of these engines performance comes from the exhaust system, you can have the baddest engine made and with the wrong pipe it will be nothing but a headache.
If you can't get a better pipe start with a longer header if you already have one, if not try the springs first since they are the cheapest option.

Hey Gregg,
I have noticed my engines run hotter with those older L2G heads. The new L2G heads on the B10 and Cross10 are much taller and cool much better. As far as a cheap head I would suggest lookin on ebay for someone that might be parting out a newer B10 or X10 or maybe someone will have an older style RB head that was before the L2G. I have never tried any aftermarket heads so I don't know what if any of those to suggest to ya.

yea il try the all gold spring setup, first if that doesnt work il take a look at the dynamite 53 pipe.
i race on a big 1/8 track with, techinal turns as you can see in my avatar pic on the left.

The dynamite 53 pipe will help your situation. Maybe the spring change will help enough to save you some money on a new pipe. When I ran an S5 a few years back the best I ever got it to run was with the RB2020 pipe but they are hard to find and kind of pricey.

I don't own a Mugen but I know several guys around here run the lightweight shoes with either .9 or 1.0 springs. It will all depend on your driving style and track conditions.

Just like Chris said I run a Mugen and have just switched over to a B10 and ran .9 springs with the hard Mugen shoes and it felt great!!!!

Well it is the header and the pipe. $130 may seem like a lot but look at the same package from OS $170. When it comes down to it these pipes will just work better on your engine than ANY dynamite or JP pipe will. If you really want the max performance and fuel economy you have to spend the money, thats all there is to it.

I have a WS7III that I have rebuild and started running again in my RC8B. Any suggestions on clutch springs and header/pipe combos? If my memory is correct, the WS7 preforms better with heaver springs? I will be running an Ascendancy 4 shoe clutch. I have a RB 2045 pipe as well as the 198 and 192 header-pipe. I was told a JP-1 pipe was a good.
