Thread: Ask your water methanol injection questions here.

reptile, u're running an M5 nozzle correct? i still dont understand how u're running a 2.8" pulley with mainly meth, possible injectors on a 12.0-12.2AFR? i cant run a 11.0-11.1 with a 2.9" on my M2(i think it is cant remember lol) nozzle. w/o maxxing my 42.5# injectors with 20* of timing.

for what its worth im using an older shurflo pump that runs at 100psi, dunno if that'll make things better/worse for me >_>

I think you're a freak.

will, i'll be planning on installing an M7 nozzle this weekend and see how it runs with it on full pressure with a turn-on point at like 9psi.

are u asking me? i *think* im using the M2 nozzle, i forgot what i have in there. however i tried running w/o any injection an aimed at running a 11.1-11.3AFR but with really low timing, like 13-14* with the current pulley or even with a 3.2" pulley. my IPWs i recalled from a run i did was in the 13-14mS at WOT(o_0?). unless my plx smr-afr wideband is messed up somehow showing inaccurate numbers, im now mainly going off of whether i'd get knock or not.
right now im debating in getting another brand wb and see if theres a difference in the outcome. and yes i did change my o2 sensor on the plx setup.

just checked my bag of nozzles and i have both my M15 and M2 nozzle. looks like im using the M5 right now 0_o
edit-i remember b4 i got the devils own controller, i was using a boost activated switch and the M15 nozzle with washer fluid. i was able to run like 25* of timing on a 3.4 and at least 19* with the 3.2" maxxing my stock injectors. however i was running out of washer fluid alot when i was spraying and since the boost activated was just at one setting, it wasnt spraying linearly with throttle nor the map sensor.

will if you're on the throttle alot, then yes....in my case i was always on the throttle on the freeway, lol. i got a heavy right foot. how much difference is it between an M5 and an M7 nozzle?

each nozzle is gallons per hour when you have it running constantly. M7 = 7 gallons per hour.

Shawn, I wouldn't recommend just shooting for this AFR, just saying what I run. I do this on a 2.8 now, and don't forget that the 100% accounts for some fuel as well. Without the meth, I can still run it on a 3.0 pulley at approx 11.4 AFR, which is still up there but not out of reach on a good tune. I think my O2's on the Denso look right at 910-920 at any given time depending on the weather. Humidity really isn't a factor in the summer, it runs just as fast when it's hot as it does when it's cold now.

Hey Brian, sorry for the late reply.

Wow, 15 psi? How does that effect the MAP (assuming you are still running a 2 Bar)? Doesn't it max out? Just wondering what I should watch out for.

What turn on and full setting are you using currently on your controller?

And when you mention washer fluid, I assume you mean 50/50 mix? I'm running a DO5 nozzle currently....

Thanks for info Brian.

Messing with my car a little Sunday i'm running a 2.9", about 17 degrees of timing (I think, need to verify), 11.6-11.7 AFR, and 0KR although i get a .5 or something spike at 3rd gear shift, I think thats false because of my solid mounts and hard shifting tranny. That of course with a DO5 nozzle and Devilsown Brew 50/50 mix. Turn on/full settings are at 4psi and 8psi. I probably need to go into full sooner, don't you think?

i dont think im even going to experiment with mixing. im just going to run straight methanol to begin with.
