Water/Meth and Pure Water

[wes06dmax]

I have had my Snow stage 3 for about 3 months now and so far I have run pure water at 100% injection med range truck ran just fine, Then the other day I stopped by the auto parts store and bought me some methanol and mixed 4 gallons 50/50 well tonight I was gonna try it out so I floored my truck and when the injection got to 75% the motor sounded funny so I got out of it come to a stop everything sounded normal drove a little ways floored it again it run like a top tell the injection got to 75% then it started making that noise again well I thought well I might be flooding the piston so I back it down to 50% injection same noise just not as loud then I back it off too 35% and it run smooth all the way, so does the meth/water mix not burn up as fast as pure water or have I got something wrong

actually the meth is what helps make a more complete burn thus giving more power. when i had it on my truck i ran 50/50 all the time with the 2 biggest nozzles. you could here the motor change pitches a little. could be timing rattle. i think you may want to pull some timing out of the tune when your spraying it.

p.s- if running only water, you need to cut your nozzle size in half or you can actually loose power( putting out the flame)

Yes it is timing rattle u need to pull timing out of thentune tou are runnin as stated above. Be careful with it mixed that much

Try diluting a batch to 25%. Some empirical evidence suggests that this mixture should have little effect on LPP. LPP is the position where pressure is highest, usually around 10-15 ATDC. The use of too much methanol can advance that significantly, causing detonation sound and component stress. You can use high concentrations, but as stated, retard injection timing to keep LPP where it needs to be.

FWIW also, the hotter the cylinder the worse this erosion becomes. IAT plays a role also. During compression, gaseous meth auto-ignites a bit before diesel vapor does, if that helps to explain.

Thanks for info ill pull some timing and give it another test run, hope yall have a good christmas
