what happens if its empty
 

just wondering, but i presume everyone always has their wi on, and since it is an aid for timing what do y'all do when its empty? change timing back to compensate without the wi? also, how often, on average, is everyone having to refill their tanks?

You just don't let it go empty lol. Refill time would depend on the size of your tank. I have a 2.5G tank and didn't refill it once for 2 months. Your best bet is to check it every time you get gas.

It never goes empty.. i am JESUS!!!! only problem is the wine keeps clogging my injectors.

I don't see how you could run out. You can get water anywhere, except the desert. If in a bind, even though it's not ideal, pour a bottle of aquafina in it or something. Hell, take a piss in it and you'd be better off then dicking around re-changing your timing. Who the hell carries a timing light everywhere. If you can re-drink your own piss to stay alive I don't see why it couldn't keep your motor alive when needed. lol

hahaha......i was more on the basis of where am I going to get methanol abundantly? and thanks for the desert idea, i can't stop thinking about how fun it would be to do one of those zoom zoom commercials and drift sideways everywhere

With a 3gph nozzle i bet you use around ~1gal a month.
You can get meth abundantly from fuel suppliers, race shops, maybe some paint stores carry it I don't know. Magnamx-5 would know, he has a 55gal drum.

every gas station in the world has windshield wiper fluid....

^Exactly even if it isn't -20. Most of it, if it has any anti-freezing capability will have meth in it.

yep never let it go dry but if you must justg drive out of boost until you get where you are going no boost=no need for WI 55 gallo drum is a lot of methanol folks.

IIRC, California has passed a law where WW fluid no longer has Methanol in it.

But, you should be able to find the yellow bottle of Heet anywhere for less than $1.50 per bottle.

California Code Title 17, Section 94509 prohibits the sale of washer fluid consisting of more than 10% VOC (Volatile Organic Content) outside of “Type A” areas (places where it has been legally determined to be cold).

So in theory you could still sell +20F fluid (7% meth) but in actual practice all they seem to carry down here is +32F fluid, which is <1% meth.

But you're right- the ubiquitous yellow bottle of Heet is avaliable anywhere, usually about $1.00 to $1.50 for 12oz, and it's roughly 100% methanol. Avoid the red bottle- it's isopropol alcohol. However in a pinch, you probably needen't bother with the meth, just use straight distilled water and take it easy on the boost.

And whatever you do, don't siphon any of the yellow water out of cjernigan's tank. :barf:

Places where it has legally determined to be cold.....


I always knew the govt controlled the weather!!

Wasn't saying I would actually piss in my tank. It's easy for me to drive out of boost all the time if I want so I would just do that till i got some water or got some meth. With as small a nozzle as I will run, I won't have to worry about filling all the time.

My friend ran out of Meth in his STi at about 29.5 psi...he didn't run out, but his meth malfunctioned and he melted a piston...

Just carrier a bottle of water :)

That kind of story makes me want to leave meth out of the picture.
Maybe that's why I keep putting off my install.

even at a 15gph nozzle it goes pretty damn slow, and mine triggers low, like 3psi.

this is why you tune off the meth and run it as a safety measure or to lower you ITT.

I go through very little in my 2.5 gallon tank. Tune the car for it to come on a little later than just a few psi if you are worried, that way you can limp home without injuring your motor.

Long Live the Communist State of California....:td:

Any problems with when the tank gets low and a long curve pushes the remaining mix to the opposite side of the pickup?? I guess if you tuned without the meth then you'd be ok. I plan to track the car at Roebling road in Sept. and it has a couple of long high speed right handed sweepers.

You can put some methanol safe foam in the tank to keep it from sloshing as well. People use it in fuel cells often.

yep foam can help with starvation issues but this is also why a full tank on the track and proper tank placement is crucial if you pump is pulling up hill wich in my opinion it shouldnt then you will have more of these issues than if you allow gravity to help fill you lines.

so by pulling up hill you mean like if the pump is mounted higher than the pickup in the tank ?

He is tuned off meth, had a 19 psi map and a 30 psi map. Just kinda happened real quick. And the meth showed it WAS working when it wasn't and it killed it.

Car still ran though with almost no compression...did the whole James Bond Smoke Screen Thing. Pretty impressive.

Miataflys yes i mean just that.

So? He was tuned off the meth but running the map tuned on the meth? and the motor went boom when the meth stopped flowing? duh.

Relying on meth is a bad idea.

After you fuck with timing a few times, you learn how to set it by feel. I can get base on my car +/- 1 deg of target without a light now... which is really about the same precision you get with the gun.

BTW, piss is a sterile solution.

Aside from the engine damage issue posed by not lowering the intake temps, I'd also be worried about the pump sucking air through the system. Which could not only burn up the pump (most pumps rely on the liquid they are pumping for cooling and lubrication) but also it would stuff additional air into the intake charge.

Ben i've ben using the Devils own pump for a couple of weeks now.

It's self priming, so if you get a air bubble it does pump through it.

I tried several times in various ways to drill and fit a pipe to feed the pump, i just could not get a good seal on plastic tanks, they all leaked.

So when i went for my go-kart tank i used the stock top feed location, so far i've had no problems.

I specifically drained out the water and ran the pump dry 3 times, every time when i filled it with water again the pump self primed.

I also believe the pump has a thermal cut out no?

no thermal switch i dont think it has one. my tap worked for me but i used automotive goop and JB weld as well as a bulkhead fitting designed to be used in tapping the tank from Snow.

I'm not thinking of an air bubble or two getting pushed through the system. I'm thinking about what happens when the tank is completely empty and the pump continues to run.

Case in point. On Friday I witnessed this phenomena.
We could get a car to crank and run for a second off starting fluid, but it wasn't getting any fuel, so as soon as we stopped spraying, it would stall. We hypothesized that the fuel pump had failed.

In getting to the fuel pump, we found some hairline cracks in the supply hose. It turned out, the car's fuel pump was drawing air through these cracks, instead of fuel through the hose. What was doubly interesting, was that there was no visible fuel leak through the cracks. I wrapped the hose in duct tape, and fuel came through the system and the car ran. At that point, I cut in a new section of fuel hose and the car is fine.

Point is, the pump doesn't care what it's pumping. Water, meth, urine, air. Whatever's at the pump inlet is going to get pushed through its outlet and eventually into the motor.

No idea if your pump has a thermal fail safe or not. But many a pump has burned up from running after it's supply ran dry.
