DannysZ28 Posted January 6, 2011 Report Share Posted January 6, 2011 I have a passion racing 4mil stock cylinder 12port motor and was thinking of doing alcohol or override. I was wondering which one would make the most difference drag racing? Quote Link to comment Share on other sites More sharing options...
sheerider1026 Posted January 6, 2011 Report Share Posted January 6, 2011 BOTH!!!! Quote Link to comment Share on other sites More sharing options...
DannysZ28 Posted January 6, 2011 Author Report Share Posted January 6, 2011 I plan on doing both. There is just this one problem called funds. Just wondering which i would see the most performance out of? Quote Link to comment Share on other sites More sharing options...
sheerider1026 Posted January 6, 2011 Report Share Posted January 6, 2011 beng i have never ran alky.. but i have owned a dunable overide.. the dunable tranny was awesome.. efinately makes u faster.. i woudn't go the alky route unless its a pure drag only bike..

dirtydownunder Posted January 6, 2011 Report Share Posted January 6, 2011 depends, if you can shift great at high rpm with out a problem go the alky conversion. if you cant shift and your loosing time, get the override. ultimately for dragging, you want both.

BigRed350x Posted January 6, 2011 Report Share Posted January 6, 2011 Go with methanol. You will wonder why you ever ran gas.... One of the first mods I do on any bike I have is swap over to methanol. Quote Link to comment Share on other sites More sharing options...

BigRed350x Posted January 6, 2011 Report Share Posted January 6, 2011 Methyl Alcohol. Methanol. Alky. All the same stuff. The chemical reaction when it burns is in my signature. Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted January 6, 2011 Report Share Posted January 6, 2011 From Wiki-know-it-all... One of the potential drawbacks of using high concentrations of methanol (and other alcohols like ethanol) in fuel is its corrosivity to some metals, particularly aluminium. Methanol, although a weak acid, attacks the oxide coating that normally protects the aluminium from corrosion: 6 CH3OH + Al2O3 → 2 Al(OCH3)3 + 3 H2O Hence the whole purging process...

BigRed350x Posted January 6, 2011 Report Share Posted January 6, 2011 Some more information about why its so wonderful. Methanol has a high toxicity in humans. If ingested, as little as 10 mL can cause permanent blindness by destruction of the optic nerve and 30 mL is potentially fatal,[9] although a fatal dose is typically 100–125 mL (4 fl oz). Toxic effects take hours to start and effective antidotes can often prevent permanent damage.[9] Because of its similarities to ethanol (the alcohol in beverages), it is difficult to differentiate between the two (such is the case with denatured alcohol). Methanol is toxic by two mechanisms. Firstly, methanol (whether it enters the body by ingestion, inhalation, or absorption through the skin) can be fatal due to its CNS depressant properties in the same manner as ethanol poisoning. Secondly, in a process of toxication, it is metabolised to formic acid (which is present as the formate ion) via formaldehyde in a process initiated by the enzyme alcohol dehydrogenase in the liver.[10] The reaction to formate proceeds completely, with no detectable formaldehyde remaining.[11] Formate is toxic because it inhibits mitochondrial cytochrome c oxidase, causing the symptoms of hypoxia at the cellular level, and also causing metabolic acidosis among a variety of other metabolic disturbances.[12] Fetal tissue will not tolerate methanol. If any of this didn't scare you away, then run it. Its great stuff. If it did scare you away, then go with the override. Easy choice.

n2otoofast4u Posted January 6, 2011 Report Share Posted January 6, 2011 Look man BIGRED might be steering you away, but heres the deal... Alky is WAY easier than most people think. Will you use a little more of it over gas, Yes. Will I need to jet my bike to run it, Yes. Could my bike be doggie on the low end, yes. (only if you dont get the carbs tuned in).. Hes the straight scoop. Ocne you get it tuned, your bike will make more power, run cooler, last longer, and smell better than it ever have before.. Im a "non purger" we run 20:1 castor 927, and I run the bitch on the hose every pass, and when Im done I push it in the corner, and wait the next race the following month. I dont purge. Some do.. Its up to you... If your scared of alky, dont be. We can get you hooked up in the right dirrection so that you setup is fairly close from the gate.

PassionRE Posted January 6, 2011 Report Share Posted January 6, 2011 If your in a position of only being to do one or the other at this time, go for the over-ride. Once your on meth and tuned properly, you wont be able to shift that engine anyway due to the high loads on the trans gears. You'll probably need to upgrade to a lock-up eventually after meth, clutches wont handle the stress...gee...the fun, or is the addiction of HP, just never ends! Meth makes power earlier, higher torque numbers, and will >>>>>>> carry a "lot" more gear and tire.<<<<<always a good thing...Jim Quote Link to comment Share on other sites More sharing options...
dirtydownunder Posted January 6, 2011 Report Share Posted January 6, 2011 you also use over twice the amount over gas..... so have a massive tank or ride very little . you should purge, maybe its different with a 2stroke, with all that pre mix, but ive seen what it does to 4 strokes ( rusts everything and turns the oil to jelly).

Its kinda tough shifting in the dirt now but its not to bad on asphalt, guess its spinning harder. Thanks for the info guys. Definitely got to get both!!!!!

theshee Posted January 7, 2011 Report Share Posted January 7, 2011 I would say an overide... my gas bike has put the hurt on a lot of banshees because of that overide... I dont see why not to just do both? It saves money to run alky, its cheaper then fuel, and coverting the carbs costs next to nothing. I have a used pingel valve if you need one.
