Found in their hyper catalog...

street nitrous:

TOP ring factor = 0.008 > 3.94 x 0.008 = 0,0315"
SECOND ring = 0.004 x bore > 0,0157"


I think thatīs it...



That number for the second ring seems too tight to me, even on motor.

I followed my ring manufacturers instructions when gapping mine for the nitrous, and it recommended a larger ring gap up top then for the second ring...Then I posted about my gaps on another board, and was told by a bunch that the second ring gap should be bigger then the first to allow the trapped gases to escape.

I would say gap them larger then you actually want to spray, because you are going to want more pill size after a while, and the larger gaps really shouldn't hurt anything...but seeing your running hypers, I wouldn't push them too much...I'd be more comfortable spraying cast then hyper pistons, but thats just me.

Hypertitics(SP?) are cast pistons, they are not forged I'll bet you meant forged pistons for all out racing on NOS or any other power adder, yes?
