16% nitro? I had a a few hours of a good run with a cold plug and 20% nitro. The cold plug is to keep the temps down.

Not sure what is best for 16% yet as i have not experimented with it.what plug did u use for your 16%.

i swear by O'Donnell fuel if u can get your hands on it. just last week some dude came to my track with a ten year old fresh 25% bottle and we tried it on the hyper engine and a rb matrix . it still is fresh ... well maybe the nitro content has lowered but the lubricant is still working wonders lol.
