Can a few of you veterans out there please offer feedback regarding this dynograph?
This is new to me, but I am skeptical here. (IMG:style_emoticons/default/confused24.gif) Thanks! Mike in Munich Attached thumbnail(s) |

1.8 crank is66mm stroke Correction. I forgot, it has a stock 2 liter crank. Is that 71 mm? Can you tell me what the volume is in total? I seem to be adding it up wrong on the calculator. (IMG:style_emoticons/default/blink.gif) |

(IMG:style_emoticons/default/blink.gif) Ok, answering my own question, for those interested...a topic that's been likely gone over dozens of times times here over the years and earning a big sigh from some veterans... 9.6 / 2 = 4.8 (formula for area of a circle...Pi x r squared: take half of diameter) 4.8 x 4.8 = 23.04 (...square that number) 23.04 x Pi = 72.35 (multiply by 3.142) 72.35 x 7.1 = 513.65 (multiply above result by stroke length...71 mm in my case) 513.65 x 4 = ~2055 ml (...multiply that volume by number of cylinders) Had I learned what I know now sooner I would have had the 1.8 heads ported and changed the valve train and cam. Perhaps another day. Oh well. Will just have to accept life with just 95 HP on this one for a while. |
