Fuel Cell Size

#1 Post by julven » Thu Aug 30, 2007 1:29 pm

What is the smallest size fuel cell that a person would want to run with 725hp motor + nitrous in a single fuel system? Also is there a preference plastic or aluminum?

1 gallon for just the nitrous is plenty big but with the motor too 2 maybe 2 1/2 min? Driving back up the return road, waiting at the scales, to the staging lanes, etc. Yeah I think I would want at least a 2 1/2.

Plastic is lighter than aluminum :-)

With a rear Chute mount I have to ditch the factory sumped tank so I might as well go small and light

Well I THINK THAT A BIGGER TANK AROUND 10 TO 8 GALLONS IS GOOD ON A SMALL TIRE CAR , ALWAYS CAN ADD FUEL @ 7 LBS A GALLON TO HELP TRACTION

I use a 1 gal cell in front for a 750hp - 555 BBC with a single plate system (only 100 shot) and have a 1 1/2 qt left in cell after a run. System holds 5 qts with lines and pump. Can run 2 passes w/o running NOS. :-) I like the weight being the same every round :D

i agree about the weight being the same, and i would fill the tank to the same level every pass, a crude way is to fill the tank then stick it and mark the stick then use it every pass. The other thing is we have to drive to the lanes to the scales and back, also some of the tracks have a long detoure for a return road, kinda stuip but hey its were they race.

I was looking at a 5 gal and there is 3 lbs between plastic and alum.I think I am going to cut some more on the car and get the alum.All the plastic ones I have had sink in the center after some age. Does anyone have a good outlet for one Summit has them for 139.00 which isn't bad.I just don't know if I have it in me to do a 1 gal.LOL! I will end up with a 3-5 gal.Thanks for the input guys!

The only thing about the aluminum tanks is they sweat at times. But they sure are purty. :lol:

you're going to want a bigger cell than that for alcohol. We run a 3-gallon and there's not whole lot left in it at the end of the run. (1/4 mile run, 1/2 mile shutdown, driving to the lanes and back after the run)
