13b N/A port timing need help
Hello,
Can some one help me with the port timin? I build n/a 13b engine with Peripheral Port. My target is 300hp I found these timings, what you think? Mazda Factory Peripheral Port: IO 86� BTDC IC 75� ABDC EO 73� BBDC EC 65� ATDC IO = Intake opens IC = Intake closes EO = Exhaust opens EC = Exhaust closes Can some one tell me good serious racing timings? I apologize for the bad english language. Please send pm or answer here. |
well, RB claims their housings can achieve 300 and from what i've read they're a little softer on power than the MFR housings, so theoretically if you use the MFR timings to build your housings, then you should achieve your goal.
if you're looking to go with custom timings, then i'm not sure how much help you're going to get on the forum. you will probably end up having to find a rotary engine builder that you can contact personally and then discuss it from there. have you seen this? https://www.rx7club.com/rotary-car-p...144200/page10/ |
