hi i have had a look at the speedway motor and read the claims of 160hp - poss or not.i know it depends on how much money u throw at it etc etc.just asking cos i am collecting goodies for my build.good a14 motor,a15 sub,undecided on pistons,spare a12 motor of which i would like to use the f/wheel plus plus.maybe s/body can give an idea how to squeeze say 180hp and 200hp i will be as happy as a pig in sh&*% ooh there is a wee little turbo in a box s/where if needed but i thinks n/a.At 180-240hp u should be with the f/runners in our clubmans
