Hi Bob the Train,
I have come across this once whilst trying to find a way to add some horses to my 4/4 1800 4 seater of 1999 vintage. I have tried many things to make the car a little bit more responsive and am at the point of fitting a 2 litre motor which would add 20bhp to the modest 115 it is said to produce. This car is a 4 seater, my family barely fit into it and the luggage the wife takes needs a motorhome I can tell you this is the most loaded Mog you'll ever see.
Looking at the cgon website all the testimonials seem to be from diesel users so it will be good on the family motor but how about my 4/4/4, do you have any comments on this.
If I did 5,000 miles this year I might use about 160 gallons and at a price of currently £1.20 per litre this amounts to 726 litres, so if I could save 20% of this it amounts to £174.00 and thus it is a 3 year payback (nearly)
OK so can I add additional driveability to the equation.
Regards
Chris
