I bought a set of their special race 572 C.I. B1 pistons for my next race B1 motor with 14.6 to1 compression and hoping to make 1000 + HP on E85 and add 150 to 500 HP of NOS. I was told by their tech guy they should live really well on the local 1/8-mile tracks using the NOS less than 6.0 seconds total WOT time using a set of Total Seal special NOS rings, hopefully race at WOT less than 5.0 seconds
