Title: Gov. Mod. = better mileage???
Post by: bryanbryan89x on September 30, 2006, 02:58:28 pm
Well, a month ago I did the govenor modification to my 1.6 na.  I removed the intermediate spring, and pre loaded the main spring.  I had my max fuel screw turned out quite a ways, so in order for the rpms to fall back down I had to screw it in some.  It's not much faster compared to my old set up, but it was still noticeable.  But the most interesting thing is that I get 3mpg better now.  My driving habit is the same 70 mph/70 miles a day.  Does anyone else notice this, or am I just crazy?

it could be because extra fuel at lower rpm's.  more power at lower rpm's means better economy (high rpm drinks fuel)
