WISECO 9.8:1 B18c pistons in a B17a. Whats will the compression be?
The pistons are Wiseco 81mm 9.8:1 for a b18c. I was told it should yield 9:1. Is this correct? I checked c-speedracing.com's compression checker but Im not sure what to put for the Piston Dome Displacement. Can any of you FI people help? Thanks in advance
edit: Using the c-speed compression checker and inputing Usdm b18c pistons I get a compression of 9.43743962996627:1. If I subtract .2(the differnce in ratio of p72 and the Wiseco pistons) I get 9.2:1. Is that right?
