172 phase 1
Hi anybody looked to match there intake perfectly to harmonic? Am currently running 120mm trumpets giving me a total runner length of 31cm where with my spec of build and with 197 cams on group N alignment my peak point of harmonic alignment sits at 36.84cm so I need a trumpet of 178.4mm really to be perfectly on point but means to be then modding the bonnet. Is it worth it above what i have here with 31cm?
