"Ron, what benefit is there in having just the one oval cutout on the TS1 piston please? Paul"

hi Paul, cannot say there is any benefit at all performance wise, how it came about was a few lads down south were cracking pistons from the window area, so we did a modification on my piston ported piston as they are the same thickness on the inlet side as TS1 piston, the oval shape has less tendency to develop cracks as there are no corners. they thrashed the nuts off them for a few K, no issues.

"Does it work on a RB22 to?" never tried them. Not sure but there may be a ring peg issue over the inlet boost port, these only just work on a STANDARD T1! plus reed valve manifold systems.
