General Alcohol Injection?

[gixrman]

Thanks for the reply Tyler, thats good to hear, helps me out, nice times to!!
What system are you running?

 

[spyderturbo007]

Part of the reason I went with 50/50 is because I still run of a stock SMIC.

You are just the person I wanted to talk to

Are you running a single nozzle or dual nozzle setup? Where are your nozzle(s) located. What boost are you activating the nozzle(s) at? Any heat soak with the SMIC? Did you notice a significant difference after you installed the water injection?

Thanks, I have been waiting to talk to someone using WI to compensate for a SMIC

I am running a single nozzle because of my blowthrough setup with a 3" GM MAF. So yes I still get smic heatsoaking. The only way to help reduce this would be to run less boost, spray with a dual nozzles setup and place one in the smic inlet (not recommended especially if you use methanol, corrosive) some guys do.

Even though your smic heatsoaks at the higher boost the 50/50 injection, when injected into the UICP or Throttle Body will reduce the temperature of the hot air comming out of the SMIC, so i am not that worried about what the SMIC does. Eventually I will be upgrading to a Supra SMIC just to get he added cooling before my spray.

I have a 300 CC nozzle located in my Throttle body elbow about 4"-5" away from TB. I have it set to activate at 8 psi and I am running 19 psi. I would set it lower if you are boosting stock levels. You want it to come on about half way through your boost. At least that is what seems to work best for me. i don't see any reason to be spraying under normal driving, when your not planning on boosting.

I might look into a dual setup later on where i have a second nozzle kicking in at 15 psi once I get a larger turbo, putting out some more power and running higher boost like 25 psi

This was one thing I was wondering about. I'm planning to do a single stage system, but still wanted to mount the nozzle on the TB elbow so I don't mess up my nice IC piping. Will this be far enough away from the throttle body?

 

[Joesmoke]

4 to 6" is suggested for a better mix with intake air and atomization, but the TB would work.

You'd just be going against whats suggested. Try it out!

Yes this works fine. I mounted it as far back on my TB elbow I could without getting in the way of the coupler holding my GM MAF to the Elbow. I have been running this for 6 months no problems. I would not reccomend having it come on at 2 psi though with it that close. 6psi-8psi seems to work great at that distance.

This was also the recommended location from the company I got my kit from. Actually after measuring the distance I am 5" away from the TB

 

[doug]

Thanks. Actually, I'm a dumbass-- I just realized that I have no stock TB elbow any more since I put in the short-route FMIC piping. I have more mounting flexibility than I realized.

 

[99GSX Swede]

!

your all set. Just be careful tapping the piping so you don't strip it out.

The key going from water to Methanol is you need to run more. I run around 1500cc of methanol this is about 3 times the size jet you would run with water. For you guys using Mcmaster carr jets the ones that have the screen on them and have to be installed from the instide of the pipe. I run the M15 size which is equal to about 3 of the largest size aquamist jets.

I find brass is the best to use with methanol and it cant be corrosive if there is no air in the systhem. I use all Aeroquip hose with brass push lock.

I by methanol by the drum with core charge for around $140

With as much methanol as I run I use the purple wire on the MAFT and as soon as the Methanol comes on at 10psi it pull 30% fuel out. This works great.

On my wifes full weight 91 GVR4 I run 25lbs 26deg timing and afrs in the mid 11s. I have driven that car on a B16g back to back 11.9@115. this is with stock injectors.

My car on pump gas and methanol ran back to back 11.4@121 with a old ### frank 2.

Just a warning for you guys that I have found the limit of stock fuel cut rev limiter and to much methanol. On our cars it is a about 2000cc. If you start injecting this much or more and ever go lean which would happen if you hit your factory rev limiter or do no lift shifts. It will pitch a rod quite easy if you are making good power.

How would using the no lift to shifts make your car go lean? Unless because boost drops some and maybe your methanol quits being injected? Seems like if you are using a no lift shift, you should be shifting the car fast enough that your boost will not drop much if any at all.

 

[LucasEnglish]

The no lift shift is a fuel cut and some spark cut on our factory ecu. The fuel cutting out with the methanol still there will make you lean.

Most of you guys will never run enough methanol to ever have a problem with this. Just a warning for those who like to push the limit. I have pitched 3 stock 6bolt rods playing with this stuff all winter. I learn everything the hard way.

I am on the stock MAS, so do you think I should go with a single or dual? I am running a EVO III 16g @ 18psi. I would like to crank up the boost some so I can increase airflow and get myself on a higher timing map (damn SAFC). I would guess that a single nozzle would be enough.

Where would the best mouning location be with the stock MAS? I have read conflicting things about nozzle placement. Some say close to the TB others say as far away from the TB as possible. I don't know who to believe

Thanks for the reply 99GSX Swede!

 

[99GSX Swede]

I would just start off with a single stage and place it in your UICP. I put it in the elbow because thats where it was recommended by the vendor i bought my kit from. Also by placing it in the elbow you won't have to mess with un-hooking the lines if you need to remove your UICP.

I have not experimented with nozzle sizing yet but with a B16G you should be able to go with like a 400 cc injector for water/alcohol. As lucasenglish posted methanol needs more but I can't comment on that since I have never tried it. Start on the safe side, you can always switch out the nozzle to a larger one later.

LucasEnglish,
You live pretty close to where I am. Where do you get the methanol from? Or do you have it shipped to you?

With my 50/50 mix, I also have the purple wire hooked up and it seems to do fine on my stock injectors. I am seeing about 18 degree timing at 6000rpm with 19 psi. I have had up to 22 degrees at redline.

 

[LucasEnglish]

Tarr INC.

 

[99GSX Swede]

Thanks, I will have to check them out and see if I can get a gallon to test out.

 

[99GSX Swede]

Tarr INC.

I just picked up a 5 gallon can of Methanol from Tarr Inc. Should I mix it with water since I am only running a 300cc nozzle or run straight?

 

[LucasEnglish]

Water is ###.

 

[99GSX Swede]

Water is ###.

OK

Methanol straight up it is.

Will let you know what happens in a few days of testing.

 

[kazzam]

I have not had any of those issues you mentioned. I got my car to the track after the switch and went from a 12.1@117 to a [email protected] with a 1.9 60 ft and trapped 122 later in the night all on a 50 trim. The car just runs better with Meth overall and i still get 2-7-29mpg and can pull those times any time i want.
Tyler

that high of a trap on stock internals? You are my hero!!

 

[99GSX Swede]

Well I have switched to methanol and so far so good. I can defiantly feel the difference in the pull I will be adding a second 300cc nozzle to my setup so that I will be running a total of 600cc methanol injection. Should be done in the next week. Just waiting on my parts

Currently am at 20 psi on stock injectors and stock smic running a FP Big28. I am not seeing any timing being pulled going from 1st through 3rd at WOT to redline in each gear. I am seeing 18 degrees at the top of 2nd and at top of 3rd by 7000K. I have not tried 4th yet.

Just wanted to add theres a guy on the DSM W/I yahoo board who runs 4 Aquamist injectors in each runner of intake, he runs the 80/20 mix I believe.
