To give some perspective on this, with the OEM restrictor in, our first attempts at refuelling took about 4 minutes for a 5 gallon can. With better venting, and some modifications to the can, we got this down to about 2 minutes and change. With the filler neck gutted, and the cans modified with a larger hose, we can now drain 5 gallons in 50 seconds or less. In our upcoming 9 hour enduro, we'll need to take on between 60 & 65 gallons of fuel - means 12 to 13 cans of fuel. Modifying the filler neck will save us minumum of 15" in the pits (45 + minutes from our baseline configuration!). That's about 5
LAPS. Giving that up versus the SE30's and Miatas that we are competing against in E2 would be suicidal. This is one of the reasons we're running this enduro under GTS-1 rules - so we can legally make this modification.
While I am all in support of limiting mods to make competition level, and more simple/cheap in Spec, this does not affect Sprint races, and handicapping the whole class versus other E2 competitors seems cruel
