Good morning Guy, I hope you're well.
My question concerns the piston ring end gaps necessary on a turbo application for an engine I'm putting together.
The pistons are Wossner items, sized at 81.43mm to fit bore size 81.50mm, so giving a running clearance of 0.07mm.
The manufacturer states a range of multiplication factors for the various applications for the supplied rings, the turbo/nitrous application being 0.006 multiplied by the bore.
So in my case the minimum end gap I can run would appear to be (for both top and second rings) 0.489mm.
Oil rings are quoted as minimum end gap of 0.381mm.
Do you have a recommendation as to what gap I should aim for?
Its something I'm tending to obsess about, worrying that theyll be too tight/wide, obviously I want this to be right before I get to assembly stage.
Any help you can provide as always gratefully appreciated.
Best wishes, Tony.
