water/methanol
 

Ive heard a few ppl mention water/methanol injection, anybody got a quick explanation about it, what its for and were its injected????

RE: water/methanol
 

its injected at the throttle body.

basically you are using water/meth to "cool" the air as it goes into
engine. its like a chemical intercooler. its only good if you're running
boost or really high compression. Will allow you to run a more agressive
timing curve and hence make more power at same boost levels

RE: water/methanol
 

ok but wouldnt the water make the engine bog???? I know it wouldnt put in as much as like a garden hose but i cant see water helping much??

RE: water/methanol
 

supposed all the water and meth evaporate before it ever makes it into the engine.
is a proven and widely used system so it must work

just have to worry about running out of juice and then have a timing setup that will cause detonation with out it.

RE: water/methanol
 

oh so it theoretically never enters the cylinder, just cools intake temp then right?:eek:

RE: water/methanol
 

right, or so little of it enters in liquid form that it doesnt effect combustion.
correct atomization as you spray it in is supposed to be very important too, so you dont have the problem you're worried about.

RE: water/methanol
 

cool thanks for the info, i dont think im planning on doin anything like that, just curious, thanks again

RE: water/methanol
 

the water vaporizes in the hot air and the methanol makes it into the cylinders and acts as a octane booster. the water vaporizing cools the air making it more dense so you can get more air into the motor and the methanol acting as an octane booster allows you to add more timing in addition to the cooler air allowing for more timing.
