I see 1.7L spec's all over the place, several list 80HP but some say 69 saw one stating 86 what gives ? All say Top End is 110mph but I just had my 1.7L at 110 and had some pedal left ?

The early 1970s was a crazy time for hp...
DIN SAE HP Gross SAE HP net JIS BHP (Brochure hp (IMG:style_emoticons/default/wink.gif) ) Taking numbers from Andy's link below: DIN to SAE conversion : DIN divided by 1.0139 gives you SAE net hp So, in our early 1.7 80DIN hp rating, that works out to 78.9 SAE hp a 73 1.7 (DIN 72) would yield only 71 SAE hp Speedo error can exist and tire size can play into that error. And yes, the 1.7 cars were all rated at 109mph iirc. Just cause you have more throttle, doesn't mean you have more speed. Its aero limited. The 914/6 with all it might (106-110-125hp, depending on whose rating you find) was limited to 125mph. |
