MS Pistons with offset bowl - orientation of bowl offset?

Post by **MiNiKiN** » Wed Dec 23, 2020 1:58 pm

Need your help!
I bought a set of MINISPARES EVOLUTION LIGHTWEIGHT PISTONS with an offset bowl - now, after I have handed them to my engine re-builder to mate them with the con-rods, I noticed I should have told him which way round to orientate the offset. <
Trouble is - I don't know and cannot find any info on that matter.
TIA

Bowl towards the spark plugs I'd imagine, like the omegas.

In hindsight that makes a lot of sense, yes

I think they're offset to improve alignment between the combustion chamber and the piston dish. Whether it makes any difference, who knows.
Pretty sure the omegas I bought in the 90's had a central dish.
