Not trying to stir the pot........but...............I have to ask,
What list of category of quads to be ran, type of porting, is this an all drag or is this Dune port race, what size piston,  how can anyone tell before hand? Length of swing arms, paddle type, size, what fuel? C12?  do you both drain the tanks before hand? and use the same 5 Gal jug? No NOS systems , weigh in on each quad? ...........Would both parties be willing to do a teardown inspection afterwards?

Or just bring the best beast you have and run it?

Lets not complicate...I only ask no overide trans.. and no Nos .., turbo,.or Liger setups,..straight motor only.
  Thats because I don't have any of that fancy stuff!!
