JDM b16a bumps CR of b18c1 engine
Guys, don't know if this sounds right, i went to c-speedracing.com. And played w/ the compression calculator and i did the ff:
Block: B18c1 w/ Bore =81mm & Stroke =87.2mm
Head: B18c1 w/ Combustion Chamber Volume at 41.60
Piston: B16a(JDM) Piston Dome Displacement at 6.93
Headgasket Thickness: OEM B-series 3-layer at 0.0290 inch
Piston-to-Deck Height: OEM B18A/B/C1/C5 - B20B/Z at 0.030 inch
The result was 11.6:1 comp ratio! is this correct? coz the b18c1 has a 10.6:1 versus the b16a w/ only 10.4:1. How could it go so high?
