An intresting thaught re Compression
Well, thinking about this today made me thaught. The AU series of 6cyls used diffrent rods and pistons to try and improve the stroke/rod ratio to get the engine to rev cleaner and higher. To do this the rods were slightly longer and the piston height was changed or the pin was moved further up the skirt. Well this brings to mind two sujestions.
Use AU rods and EF pistions to achive super high CR. This would be dictated by the increased length of the rods and if the extra height pushed the piston above deck height. If not this would make for a nice high CR N/A race motor. Say 12.5:1 compression
The other school of thaught may also hold. Use EA/L rods and Au pistions. This should see the piston sitting further down the bore at TDC, thus reducing the CR. Perfect for big boost turbo applications.
If the demensions work out, (read: the pistond dont hit the head/valves or the CR gets way to low), it would make a good alternative to using custom forgies in wild applications.
just a thaught........
Ive been described as a vault of usless random knowledge.
Ill take it as a complement i think.............
