The person to ask is John Klutz at CKI. The pipe/header that will be spech’d is actually an RLV setup made for the X30 in a laydown. It is a close copy of the IAME setup. At the spec length for the flex which is shorter than for sprints the motor pipe combo makes about 36 hp. I was told this would be a X30 motor only class. Engine rules will mirror the sprint tag rules for the X30 with some changes to make it work for a laydown. The choice of the X30 only was to keep costs down. The test kart was run for 7 race weekends before a new piston was fitted. The piston still had coating on it & was turning fast times. The bottom end has yet to be rebuilt after roughly 1 1/2 years of testing. The drivers for the testing were picked from the top road race drivers in the nation.
I bought my motor package new for under $2600.
