Koch’s SRX pistons

Would like to thank Koch’s Performance for keeping our 340 SRX on the race track with their piston kits. Koch’s got us to the winners circle once again.

Thanks Leon and Penne for providing engine components that would not otherwise be available


Used Phazer engine success.

Thanks Leon for getting me that used 480 Phazer motor at end of last winter. It’s in sled and rocking. Oil level going down in injection tank and still running premix for a little while longer. Ken Murphy. Roselle IL.
