We can get up to 11 min 20 sec on a stock 5 port in a buggy and we have gotten 13min 15 sec out of a truggy . You can get these times , you just have to know how. Mind you these tank times arent aimed at engine longevity. At these times you would expect your engine to last 20 to 22 litres tops.
We tune most of our teams engines to about 9 mins on buggy and 12 mins on truggy depending on the surface. High grip surfaces will use more fuel. With this tuning we are getting 35 litres + thats about 9 gallons . All this will depend on the quality of your fuel. it has to have a good oil in it to reduce wear.
Hope this helps
