Default RE: RC Car Actions "How to port a Nitro Engine"

ORIGINAL: SAVAGEJIM

Does anyone know what grade of alum they use in most engines? Particularly, I'm looking for the alum alloy that the K4.6 uses; I want to calculate the new failing stresses for the conrod I modified. If anyone knows this, please post.

Also, I attempted to port a sleeve just last night, the attempt was an aberration. Looks like I need more practice; good thing the sleeve was junk to begin with.
For the conrod I would guess 7075 probably tempered T5 or something. The piston in all engines are high in silicone.
