Improve or shoot down my idea!

okies, I'd like to be able to mount a small moon style tank up front. Anyways, in this tank, I want to keep 112 or so and then use an electric tank switch valve and a small electric pump and should be able to switch to the good stuff and idle it through for a second or so and then switch back to regular fuel in the tank when done playing. Add this with electric cut outs.
Good idea or no?

 

Not sure what all thats saying,,but why not just run teh same set up as an old dual tank pick up truck?

just a diverted valve right and 1 fuel pump ?

 

The bad idea here is a a small tank of fuel acting as your front bumper on a street car.

Find a way to do the same thing with a rear mounted fuel tank, and use the Moon tank for a radiator overflow tank.

 

Either the car needs 112 or not. There is no magic in 112, it will not make more power if the car is set up to run on 93. So I'm failing to see the point.

 

112 octane burns much slower than 93, and will not give you the results you are looking for. It's not like a shot of nitrous.

 

An engine that truly needs all of what 112 has to offer when it's time to 'get it on' can run around on 93 under light load, so the idea does have merit.

 

agreed no doubt.
I was thinking this could be the fuel that is run via electric pump for the motor and also the nitrous wet line.
Definately can run around on 93 and advance the timing in cab with the crane ignition, ****, can set it up to retard under spray, switch tank valve, and wait a few for it to purge through and be playing with 112.

I will use a small cell in the back, would be safer than a moon up front.

 

If that tank is for using nitrous, just pressurize it. The gas solenoid will stop the fuel flow until needed.

 

A dedicated tank for the nitrous system is fairly common but I don't think pressurizing it would be a good idea since a set fuel pressure is critical for it's use. Just run a separate pump and regulator w/a relay switched from the nitrous arm switch.

 

What's the toy this is planned for ,Tim?

 

A motor in need of 112 might put around on 93, but it won't be very happy about it if you need to give it a nudge for some reason. Are you sure you want to risk even a little detonation on a motor that had the $$$ in it to need 112?

Use cable operated cut outs. That electric **** is for chainers.

 

no no, wasnt going to pressurize the nitrous, I was just saying, I have a "wet" kit, it has fuel selonoid, when you hit the NX ****on, it sprays additional fuel, might as well have the additional be 112.

I think you are waisting your Time and Money. Without changing the timing to accomodate the difference in Octane i don't see that you will gain much of anything. Just my opinion.

 

Sometimes it helps to read BEFORE you post

 

uum, hows about reading the thread? As I said earlier, its all about being able to change the timing from in cab. You can tame a beast and run on 93 with the correct timing changes.
this thread was for the hope of getting good ideas on how to do the fuel routing, not the timing, that issue is whooped and handled.

 

electric pump and reg. for the secondary tank, and a little ball valve is what i would do. then run the fuel lines under the floor, and cut a little whole for the valve lever to poke up through, you could be sly if you want and hide the valve under the seat or something

 

Unless you are going to attempt to get away with running a mechanical pump you would have to dedicated electric fuel pump just for the Moon tank.
An inline solenoid valve or as mentioned above electric tank switching valve for a pickup should work if it will flow enough fuel. From what I am reading in your posts the intent would be to be able to operate it from inside the car without getting out of the car to open and close valves.
At least it would be a Moon Fuel tank out front with fuel in it instead of another poser accessory like most of them are.

 

my cousin has his drag car like that so he can also run alcohol and run in different cl***es with the flip of a switch. He was saying that he had to make sure the fittings and electric pump were rated for both. He said it works great

 

Biggest problem you're gonna have is you'll have to flow 1/4th the tank volume to flush out the lines and carb. It's not gonna be instant and will require some preparation. Personally I'd use a complete setup from a dual tank pickup instead of reinventing the wheel with some kind of cable operated br*** fitting stack from the plumbing aisle.

good luck

 

Yep, the detonation you can't hear is as harmful as that you can.

 

no plans on hoboing the construction and the dual tank with the factory electric switchover is the easiest, just dont want a huge second tank.
easy enough to rig up I guess. May just say screw it, load the tank up w/ 112 for a night of play and set timing for it, that way your stinkin' up the joint everywhere you go.

 

I really don't understand the point of a separate tank for better fuel to switch at idle to do what ?
You will be making a big mistake and you will be looking for a engine rebuild soon Too !

 

I think your original idea, the way you described it, would not only work, but work well. I could see some sort of valve in the carb inlet line that lets either feed line flow, like a truck dual tank switch, and then just turn one electric pump off, and the other one on. This could be all electric, and simple to do. Go for it.

 

sigh.....
just a bunch of jibber from the unknowing.
believe it or not guys, there is a ****load of high horsepower cars running on 93 and switching to good stuff to play. Its all about knowing what your doing with the timing etc.

I'll figure out the tank and valve stuff, should be easy enough to locate.
fyi,
I had a 500hp 4 cyl that was daily driven on 93 and 12# boost, would switch to 112 on friday nights, up the boost to 25#, do the timing with the laptop, up the fuel pressure and install a 10# bottle of nx. = instant monster.

the reason of this thread, trying to find a clever way to have 112 on board w/o having to drive on it all the time.

 

Yeah but that other ride probably had a knock sensor a****st other things like fuel injection. I think you are trying to over simplify this.

 

no sir, ran it with a piggy back computer, all the factory stuff was disco'ed.

whether the motor will survive isn't even a factor in this equation. I know for a fact it will live on 93 happily, its not my first rodeo, nor my first motor.
Again, I was just looking for creative ways to carry the 112 and switch it, maybe a few gallon tank, but oh well, this thread has gotten so far away from what I keep returning it to........
nevermind I guess is in order.

 

This is a nitrous car?

I don't see whats so dificult here. An electric fuel pump and a check valve in the main fuel line would do the trick quite nicely.

 

I think you may have misunderstood me. I was ***uming you were considering running a separate fuel system for a nitrous kit.
