REX P5
just had my first offroad race with my new P5 and all I can say is AMAZING! had to install the restrictor just to keep from blowing the tires off of my buggy. never ran over 215 all day until the main when I had to run some Odonnell fuel and it went to 230 degrees. SMG fuel is the best Ive ever used,It left a beautiful bronzed color in the chamber and crankcase and never flamed out all day.
