Any more 170+ mph runs planed for the replacement motor ?
Was that last 176 mph pull on gasoline or E85 ?
Any other engine assembler fretting over a couple 1/10’s of CR would cc the motor. You might have more fun cc’ing it than playing CR calculator shuffle board with more than a few...
LUND gave the OP the 12.0:1 blessing so here’s opening another can of worms.
11.0:1 is remarkable for 91/93 reformulated gasoline, 12.0:1 is mind numbing to guys over the half century mark but we know it’s DI magic.
All very good questions for a thread related to the topic so start your own and see where it goes.
I see no need to post up some data from Swain or a few others I have. I’ll stick to helping the OP within his scope and budget.
Have a good evening.
Just wondering, did you miss my post about the pistons skirts being burnished to the bore ?
Applying DFL to the used burnished piston and reusing the seated rings the DFL coating will transfer to some degree to the cylinder walls and will raise the possibility of ruining the ring seal.
You need to go back and reread the 8 pages of regurgitated “WOW”
We all know the OP was reusing the pistons and rings on pages 1 & 2. Some are having a hard time wrapping their heads around that.
