Ian used to spend *hours* grinding out the ports on the heads, all by eye using a die grinder on a flexi shaft to his pillar drill, constantly checking wall thickness. They all looked identical at the end.

Andy, great to see the Imp engine still being developed! I once owned a Paul Emery 1150 engine, I never had it running as I dicoverd a crack in the block under the centre main bearing, it was a Mk1 block and really not ideal...super video, thank you.

Ports of that size are allways going to make torque high in the revs. Old factory R17 is still above 5k on a 1.2 bottom end. Never stop learning👍

Why no support for the rear main bearing? If thats the one that has as much, if not more load that the other two, with flywheel & clutch loads, etc?
@thehillmanator
Жыл бұрын
hi, the rear main cap is fully supported down each side by the block and has the sump bolt to it as well, it is simply better left untouched in my opinion, the caps are made from LM 24 and very strong.
