Bio Ethanol running 1200 bug!

Post by HOT 1200 »

I just spent 4 weeks running my 1967 1200 bug on Bio Ethanol...
(purchased from Morissons)
After some serious 'up jetting' of the stock carb, I managed to get the bug running right...however MPG was down to around 17-20mpg....!!!!
(Running a 170 main jet and .80 pump jet)

Bio Ethanol is around 35% less volatile than petrol, hence you need to add 35% more to you fuel/air mixture....

Im back to petrol now because it was costing me a small fortune, although I did enjoy the sweet smelling exhaust and the very Cool Running engine temps....!!!

I was wondering about this as E85 is being seen at more stations...
and was about 45 cents L (35p)
Ethanol has a higher knock rating though, so can use higher CR and more advance on the timing..
My "DJ'd" DG, might work a little better...
PM'd yer
