I was thinking...

At my mechanic's advice, I won't run more than 14 psi on 93 octane. Occasionally (on the weekends), I'll get some Unleaded 100 octane for $4.36/gal and crank the boost up to 17 psi. Would it be ridiculous to try a 2 gas tank setup? One for pump gas (large, obviously) and another smaller tank for race gas. I know a lot of buses and big rigs have multiple tanks and obviously they have a lot of room for them, but I was wondering if it would be possible to install a separate tank.

I'm just throwing the idea out...

 

i plan to do this, 10gallons for 100octane, and 10 gallons for 93 octane, essentially two fuel cells in place of the current stock tank

then i'm going to use nitrous solenoids/valves to control which fuel i'm running, the trick will be to switch them in the right order so as not to mix the octanes too heavily

 

Can this be done with one fuel pump? What exactly is a "fuel cell?" They look awfully small from what I usually see on TV. Does it put the fuel under pressure or something?

 

I was actually thinking about this the other day and thought about a small fuel cell in the trunk same thing 100 octane to fun on high boost then a switch to regular gas for everyday driving. I think this is a great idea.

 

it has foam in it to prevent sloshing, a sump system to prevent running dry and they're indestructable

 

There made for just a few runs running the high octane gas. This way whenever you want to race. Boost Controller set on 15 psi ( or w.e) switch to 100 octane and bam your set to go.

 

why not run C16??? it cost jsut about the same as 100octane but has 117 octane rating.

on another note, should you be running such high boost with so little knowledge of automobiels? I mean you don't even know what a fuel cell is and/or that you dont need 100octane to run that psi boost (its all about the amount of fuel and fuel delivery, octane is just to mask problems or for safty...). Are you just upping octane and then upping boost (cuz if your are, that aint too smart)?

and yes you could probally rig some thing up via an external fuel pump with cut off switchs and Y fittings but why not just buy another fuel pump?

 

Just a thought, maybe you could use a fuel tank selector valve from an older truck which ahs multiple tanks. They are made for fuel and they are kinda cheap too, about $20-$30 from a parts store.

 

How much extra weight would two fuel cells be opposed to the stock tank? Same? More? Less?

 

wow this is some creative thinking!!!! Sounds like a very interesting idea and I hope we get some pics when you have this done.

 

call me crazy, but why not save the hassle for other things and the trail blazing to someone else. take the 5 minutes to drain the tank with the drain plug on the botom of the tank.
93 on the street, C16 at the track.
look how much money and time i just saved you. LOL

 

If your going to run two tanks each one needs to be setup like it's the only one. I have a dual tank setup in a 61 ford short box pro street truck. Fuel cells can be from 2-15 gal sizes so finding something to fit will be easy. beware that to high of octane can be a performance loss. You need the compression to match the octane. The higher the octane the higher the compression needs to be. Weight difference between the two won't make any difference. Good luck

 

Interesting idea, but I think it'd just be too much money and hassle to set this up.

 

OK, you're crazy!

 

i love you ron.

 

pianoprodigy has a great idea ,me personally i`ve been tinkering with the idea of a small tank of c16 to run some nitrous maybe a 75-100 shot ,of course just an idea ,dont know if it will work ,run high boost (maybe 17-18psi) and nitrous will be injected with the c16 ,again just an idea ,i am tryng to work out a layout

 

Let me clarify...

I know what a fuel cell looks like, but I just was unsure of how it actually worked.

 

bye the way sweet ride looks nice

 

There was a threqad in the louge about that purple supra with that crazy jap looking abflug body kit and he has tons of picture of his dual tank setup.

Back from the dead...

Did any of you guys actually end up moving on this idea of a dual fuel tank setup? And if so, how'd you go about doing so?

Oh and Luke, I couldn't find the thread you were referring to...anyone got the link?

 

I did it three or four years ago.

 

Kevin, didja really? Have any info/pics/writeup etc you'd like to share? And your impressions/experience w/ it (good, bad etc)? Cuz I'm all ears...

Feel free to post or email me if you'd like (The944@aol.com)

Much thanks

bump...anyone have any info?

 

Still lookin for info about this...

 

See the drain plug:



This is the most logical way to go. While two tanks sounds nice, it is really not very practical. And when you get down to it, you know when you will be needing the extra boost and when you won't.
