Mikähän mahtaa olla sopiva välys lohkon poraukseen kun wisecojen halkaisia 91.6mm? 2 eri asiantuntevaa(?) koneistamoa antaa ristiriitasta tietoa

Ei tuossa Wisecon sivuillakaan oikeen selkeää ohjetta ole. Suurella porauksella pitäisi olla vastaavasti suurempi välyksen lisäys (mun mielipide).
2. What kind of piston-to-wall clearance can I run?
The factors that affect this are cylinder wall thickness, whether the block is filled, the overall compression height of the piston, piston material and thickness, and whether a marine engine is to see fresh-water cooling. Most small blocks get .004 piston to wall clearance and most big blocks get .005 due to the use of our 2618 high-strength alloy. For heavy blower and nitrous applications, Wiseco recommends adding .001 to the standard clearance. Special note: Clearance numbers are taken 1.300 down from the oil ring land-Not 90 degrees from pin centerline.
