r/atvshee Posted April 20, 2009 Report Share Posted April 20, 2009 Over the summer time, I plan to start over and build a 4mm drag bike. From experience I know that the 4mm cubs make alot of power, but I was wondering what everyones opinions are about the 4mm super cubs and if it'll be worth it. Im not too worried about the cost between the two, I'm mainly wondering about the power difference between the two. Thanks.. Quote Link to comment Share on other sites More sharing options...
shanYE west Posted April 20, 2009 Report Share Posted April 20, 2009 power differnce between the two is about 2-5hp depending on the builder. The 4mil super cubs have to be ported or they will make less power over a unported cub. Quote Link to comment Share on other sites More sharing options...
