what compression ratio are these? are they for a low compression single cam head, or a twin cam head? phone or text o4o4978589. thank you.

hi these are the specs i have if you need any more info contact david bird at mahle i did work out the comp ratio once for a twin cam head using these figures i think it was 8.5:1 but you should be able to work it out with the specs below

COMPRESSION HEIGHT: 32.100 mm

BOWL(-)/CROWN HEIGHT: -2.50 mm

BOWL/DOME VOLUME(-): 12.00cc

RING SET SERIES : M1686

PISTON LENGTH : 64.000 mm

PIN DIAMETER : 21.000 mm

this is the formula for working out compression ratio

one cylinder swept volume + deck cc + head cc

deck cc + head cc

Example: 545 + 3.378 + 48 = 596.378

3.378 + 48 = 51.378 = 11.6:1

In this example, 11.6:1

the deck cc =12ccs

neo head has 50 to 54 head ccs

using this formula and these pistons bore would be 87 stroke 85

gives a 3031 ccs with a swept volume of 505.29887 per cylinder

so 505.29887 + 12 + 50 =567.29887

12+50=62

567.29887 %

62 = 9.1:1 this is the unadjusted compression ratio "dosnt include head gasket

any change in any of these figers will change comp ratio so ceck what you have
