That is rather funny. even an spfi sube from 1985 with singular injection got 38mpg all year5 round in maine...-30F to 100F. there is a bullcrapper in the fuel air world, it has elctronics to blame all over it.
I got a kick out of my 1987 carbed sube (nothing fuel heated) and recorded it at -18F in anorth wind, going up the highway. the heatinside the car was clombing out hot, and I still had to pull over. and it got the same fuel mileage as always on the highway.
It may be a decent fact to keep fuel source a to b out of the wind and elements. the fact that it is flowing heats it. And the miracle for fuel injection pretending correct mixturers (all my carbs and the electronic SPFI sube are the worlds greatest, no lies) Fuel has a return line for unjecteds, the fule pump is hella fast. Again crabs make that very pump an idiot, at <3psi...and startign in all weathers.
Maybe a boigger crushing than the big 3 is in order, I defend myself. Let us not all bow to babbling math and slow chips.....
To finish off my mispelled babble: all vehicles for a given bore and stroke have a tuned intake for the 87 to 93 octane. Electronics did away with that perfection.Intakes are now slobs of wannabe oversized man parts."Look at the size of my... intake. yes intake manifold." the very few years it over lapped with singular throttle bodies were american failures. the oldest subes with the first injection singular, was and is a genious with it form the same time frame.... an epiphany I have not forgotten.Even the ecus were low micron and slow reactors.Why didn't the rest of the world catch on? Why didn't singular injection and tuned intakes catch on? A dollar sign followed by 7 zeros changes alot of minds....
