Has anyone ever run out of alky?

I am curious? Due to the location of the supply line from the coolant/meth tank supplied with the Razor kit.

Last night I took a ride down my favorite test track. The tank was about three quarters full with straight meth. Upon full throttle acceleration my low level light comes on for approximately 3 to 5 seconds. Apparently the full throttle acceleration G force made all of the meth go to the back of the tank. This is concerning to me. With my setup I run 93 oct. 25 lbs boost. I'm sure if I run out of meth during a run it may get ugly. I have had this happen once before during a run at the track. I showed some knock retard and lost ET and mile-per-hour. I know the solution to this is to always keep methanol tank full. But in the real world driving around town this is not realistic.

Any and all comments appreciated.

Keeping it full to the topi s the ONLY option. I keep a washer fluid jug of methanol in the trunk. I top it off before I go out.

i made mine rear exit
i have trunk mounted battery so i mounted my stock alky tank where the battery was
flipped it around 90 degrees counter clockwise , drilled a hole in the wheelhouse so the outlet fitting sticks out into the wheel well and used the hose supplied with the std alky kit
an easier fix would be mount a small reservoir inline under the car by the pump (like under the battery ) , something like the vacuum reservoir ball thats on the driverside , the old hotair vac reservoir would be fine too , drill and tap two fittings into it on top and one toward rear , cut your hose from tank run it to the top and run the rear facing port to the pump,
 
Get a metco 5 gallon fuel cell for the spare tire well. Never run out with that... was my plan for the future.

the metco ..if you can find one i thought they were all gone and shows out of stock and has been for a while ..still needs to be rear facing outlet to supply fuel on a hard hit high G situation as you would with a sumped tank or fuel cell
not sure how razor feels on this but if i did the metco rather than have a -06 suction line run forward the length of the car i would rather have the pump on the rear bumper and run a -04 to the front ,
and adding almost 7 gallons of meth to the trunk and an 8 lb tank adds almost 60lbs to your car (thats .6 tenths it wll slow down)
and its a fuel cell youll need a firewall installed behind seat /pkg shelf to pass through tech if they find it there
also make sure you run a vent tube to the outside of trunk

yes it should be as mark did with the addition of what i mentioned above
 
Couple things..
1st the floats are technically designed for a density of water which is 20% greater than methanol. What that means is methanol is way thinner as a liquid than water, so things don't like to float in it. Its very easy for it to dip into the methanol especially under a hard launch. 2nd. the pump having it head way below the tank has 30 inches of hose full of fluid at its disposal.
Just because the float bounces doesn't mean your starving the setup. Yes once it does get very low, you can have pressure drop under hard launches.
A lot of times I see more of an issue with the system needing to be purged(hit test button) more than having an issue with starvation.
Ultimately if the car goes to the track, puts the wheels in the air, and has that type of wonderful drama.. maybe a fuel cell would be better. I just don't see a street car on a regular paved road creating enough G-force to really make any difference.
Dont fret about the float.. its just an idiot light to let you know its gone down.. if your truly want to know whats up.. datalog the pressure with your ECU.. then you will have "answers".
HTH

Reading through this.... Wouldn't only be a 6 HUNDREDTH loss?? Thought the equation was 100 lbs per 10th....

I mounted my pump on the other side of the car and ran more line to the pump,not sure if this changes anything but i log pressure and it is rock solid.
 
Funny thing how when you have the "data" you can pickup on the little things.. I always recommend on a faster car to get as much logging done. Fuel, alcohol, air fuel, etc...
