Hey Mark, what's the ONE thing that really matters when building racing engines?
"EVERYTHING."OK, getting back to the fact that details matter . . . . . . .
More photos of the new solid copper head gasket, this time mated up with the cylinder head,
and Vs the stock Rover MLS gasket
rear segment
front segment
It appears to be a very good matchup to the cylinder head, although there are obviously some dimensional differences:
New copper gasket: .031" thick x 76.5mm bore Ø ~ 3.62cc
Rover MLS gasket: .091" thick x 82.85mm bore Ø ("flat" MLS section .069" thick) ~ 9.45cc
a 261% increase in just the gasket volume!!This little detail would necessitate a dome volume increase of 5.83cc's, just to
maintain compression ratio!!
Carbmonkey says: "It's complicated." Because every detail matters.
