I have a question about boost. I am just getting back into racing electric after racing only gas for a long time. I was at a race this last weakend and saw a boosted 17.5 setup that just ate my 10.5 alive. I also seen this pro running a boosted 13.5 in the mod class and was doing everything the 8.5 and 7.5 guys did. So my question is what would the benefits and\or drawbacks to running say a boosted 13.5 or 17.5? The pro I spoke to said he likes the boosted 13.5 as it is smoother than most 7.5,s but will run right with them especially on indoor tracks. What are your thoughts?
