GAC Engine Calculator

Use this GAC Engine Calculator to design your engine specification

For example: Change the chamber volume (head cc) required for a 1776cc engine when targeting a compression ratio of 9.2:1 and a deck height of 1.25mm, plug in the following numbers: bore=90.5mm, stroke=69mm, deck height=1.25mm with the Camber volume to some where around 46cc. and experiment with diferent volumes to achieve desired Compression ratio ….. and remember to input the correct deck for your engine or see the differences in compression ratio with different deck heights
