quick question, is there any advantage (or disadvantage) to stashing some methanol in the fridge and letting it get really chilly, then filling up the meth tank with it? Not sure if this would be bad for the supercharger or engine due to thermal shock or something. my reasoning was because its hot here (GA), during the summer, and even at night it stays quite warm. there are Friday night drags at Atalanta motor speedway and wasnt sure if taking a mini cooler with some chilled meth in it would help at all?

 

I've heard if you put sugar in it, an mix with water it makes for a good drink with some Absolute Vanilla..

 

ill keep that in mind for happy hour.

 

Won't make a difference, anytime a compressed material becomes uncompressed it absorbs heat, thus making it cooler.

Go floor your car then pull over right away and hold your hand on the piping just after your meth nozzle, the pipe will be ice cold.

 

didnt know that. thanks for the answer!

 

yeah no point to it. just run it normally and you will be fine.

 

Not a problem, I've seen condensation and even sometimes frost form on intake manifolds from people spraying meth as it gets so cold.

The vaporization of a liquid is endothermic, meaning anytime you take a liquid and turn it into a gas it absorbs heat. When you spray meth, due to the liquid being under such pressure and then squeezed through such a tiny hole it causes the liquid to vaporize and turn into a gas, basically.

The same thing happens with your fuel injectors, you just don't notice it, however if you have ever seen a video of someone running ITB's with external injectors, the trumpets on the ITB's will have the same condensation on them as someone spraying meth due to them getting so cold from the fuel (which is under pressure) turning into a gas state.

Same reason why those cans of air dusters get cold if you spray them long enough, or a tank of propane.

ahhh,, great info fellas. thanks a ton

 

Yeah don't do that, methanol is toxic. blindness or death may occur . stick to *Ethanol*

 

^^Eventhough I'm sure they were joking, formaldehyde in the liver is no fun.

 

LazerblueSS - overall yes - meth can be chilled to produce more HP/TQ, after researching the idea with a chemist & physics at school, they both told it is possible, but the problem lies within the following questions:

- what is the ratio of water/meth is in the mix: because of the freezing point of water, in which it could turn the mix into frozen slush maybe? even though the water & meth isn't going to be frozen, but the coagulation of the mix under a cold/chilled temperature could turn it into a slush..

- the nozzle size [hole]/output pressure [pump pressure]: size and pump come into play here, because the coagulation & atomization of the mix when it is pumped to the nozzle - could it turn into a liquid or slush state? reason here is to make sure the nozzle or pump doesn't get jammed or clogged..

- boost temp/ pressure: this is the key to the problem, because the outside air & boost temp is always changing due to weather and elevation.. if the boost temp is too hot, it could turn the mix into steam or too cool, it could turn the mix into liquid..

- ignition degrees: adv or retard?

- fuel type/temp: ?

all of this comes into play.. once you have all of the answers to the questions - then I can get a mathematical formula in which it will give the ideal temperature for the mix to spray at.. it is a balance game in the end..

 

Again, I really don't think this is going to matter.

The vaporization of a liquid can reach temperatures of -50*F.

Given the average household freezer is set to around 0*F, its not going to make a difference.

And where are you gonna find a freezer at the race track, the amount you will be able to cool the meth won't result in any noticeable gain in power due to the resultant change in air intake temperature.

Also, the the mix of gas/water/meth is always vapor inside your cylinder...so there is no worry about "the boost temp being too hot".
