Last Updated: Jan 11, 2006 H/F-Series Compression Calculator v.50 BETA This calculator is intended for use as a general estimate of your compression only. Not all values are verified, if you have verified values, please email them to me @ compcalc@zealautowerks.com NOTE: H/F-Series info is still limited, some values have not been verified and act as more of a placeholder until correct values can be found, so please use this calculator accordingly.
