Frankie and everyone else, here are the engines I run. It seems as though not too many of you are familliar with RB, the engines range from mild to totally balistic. I've been racing with RB for over 10 years and never had an engine failure, Very fast, consistant and reliable engines! Take a look at the site, it's got some great information regarless of what engine you run. Enjoy!
