os rg .21 what pipe
 

what would be a good pipe for a bigger track im looking at the ofna jp pipe line.

jp 2 would be perfect that motor is bottom end motor

The OS 2030 pipe is made for the RG.

I ran the Nova 086 pipe with short header and it was ballistic up to a 110' straight. If its a bigger track just put a 14 tooth CB on and it will run with the best of them.

:)

what kind of temps does this motor run good it is slighty moded and has the nova head on it

also whats a good plug for this

os#8

with my rg i ran a mc59 plug. and a os2050 pipe:nod:

so these are hot plugs right. when i was running 1/8 buggy i was always running mccoy 9's nevver had a problem so whats the big diff from hot to cold plugs.

I would reccomend sticking with os plugs. OS plugs are short plugs, whereas plugs like the McCoy plugs are long body plugs. You can use long plugs but you have to(or atleast should) run two copper washers with it instead of the standard singl washer.

just for everyone to know about mc59 plugs. i ran 2 head shims and got 8 gallons out of it.

O. S. A3 plug runs great in that engine with 30%. RG runs a little hot with the stock head (250'ish). You'll have to be careful with the aftermarket head b/c it will cool much better. Tune from rich to lean and make sure you have smoke throughout the powerband and you'll be all right. I use a JP-1 with mine on short tracks, but JP-2 is probably a better choice on a little bigger track if you're sticking with the Jammin pipes.

is the a3 a cold plug

OS calls it a hot plug. About the same as the #8 I think, just a little warmer.

so what are the pro's and con's of hot and cold plugs for this motor
