fuel use per pass MFI
« on: November 11, 2020, 09:59:42 AM »
Wondering what kind of mileage you guys are getting out of MFI, Ok how many gallons per 1/8 or 1/4 pass with driving up and back. I know my stuff needs some tunning and is rich.Been a while since tuned injection w/o a blower under it. Few pass' I have manged to get in this screwed up year. Driving up and back 3 1/2 gallon tank had me coasting back.Now Idi have to follow some retards dwon return road who couldn't hears a 13:1 500 inch Hemi with zoomies whomp whomp the motr to get the xxxx out of the way.

 Like said I need to lean it all the way around and have on idle side and little on  WOT. Thinking about swapping to larger tank and if knew eight deal with front I wouldn't have problem after all each gallon about 7.8 lbs..  Plus heard that in bracket racing weight is not big deal,thats funniest thing I have heard. How much are you burning?

I too run a 3 1/2 gallon tank.  On the 1/4 mile I can make it back to my pit under my own power but I'm runnin' on fumes by then.  Mine is a injected 557" Ford 15:1 .  I hate it when I get stuck behind those lollygaging dingle berries.

358 SBC a little over 500hp about a gallon for 1/8th mile.
When we ran quarter mile closer to 11/2 gallons with a long shut down.
I have a 5 gallon tank that saved me a couple time I forgot to put fuel in.
