My thoughts about meth injection

When I spray from a roll say 50+mph, the car pulls hard and acceleration is nice and brutal.
But when I go from a dig and the meth activates(7psi preset) it'll pull hard up until I hit full boost(15psi) once it hits full boost the acceleration goes soft like its pulling but not very hard. A/F is 11.5 with no KR showing up on my HPT stuff.
Does this mean that my nozzle might be too big and is overwhelming the car from a dig?
From a roll its freakin mean

As far as how much it consumes... the $3.50/gal i pay for meth more than pays for itself with how much boost i can run on this stock engine.

Are running the Vari Controller? If so did you set it up via software or are you using 1 of the 10 preset programs?
What did you use for a tank and where did you mount it?

i have the alky control kit. julio is very helpfull, dont call him unless you have a little time to get educated 
.
i run strait meth like julio sugests. i have it turn on at about 4 psi and have the gain turned to max so the flow rate goes up prety fast as boost goes up. i had to pull a lot of fuel to get the a/f right. if my wideband goes much under 11.0/1(reported on the gauge) it starts to flood out so i shoot for 11.5/1 just like i would normaly. i have 2- 10 nozles, i dont know what that 10 stands for.
i have a 4 gallon cell for my meth, it seems like the level never changes. knowing how little i would go thru if i were to build another set up i would go with a 1 gallon tank somewhere under the hood. i spray more than most and only go thru about 1 gallon every few tanks of fuel.
i was able to go from 11psi max no knock with 92 octane all the way up to 16psi with the meth. thats around 200rwhp on my set up. thats around 750rwhp. it actualy dynoed over 1000rwhp at 22psi on pump gas with meth but this was on a dynojet and as we all know the load isn't acurate and i had to turn it back to 16psi to avoid knock once on the street.
my intercooler is prety small for my set up. i am steping up to a larger intercooler set up and hope to do the aftermarket aluminum intake to even out the air flow and i also plan up uping the meth flow. i wouldn't be suprized to see over 900rwhp with meth and 92octane.

So what is your consumption-MIX? Are you running one nozzel or two? What size?

Brett Foote Question for everyone running a meth system Since it pulls harder/boost faster when it kicks in, would it be worth while to have it start injecting at 1psi? Currently I have it injecting around 3 or 4.
about how many miles out on the street or passes will a 55 gallon drum last? Could it last me the whole summer on the street and a few trips to the track?

i run a 509 on meth also... thats why i buy soo much
i was just giving an instance

Good info Parish.
My car "feels" like its flooding out as well. I'm in the process of trying to bring the a/f back to 11.5-11.8 like I'd run off of meth. Seems to be responding very well. My testing today felt real good, no KR but it did bog a bit on intial hit but cleared up, nothing like it did yesterday.
My a/f was dipping around 11.3-10.9 today, yesterday before the tune adjustment, it was 11.1-10.5 and bogged bad and had a bit of KR (1.5 deg) too much fueling I guess.
I'm thinking my nozzle is way too big and is causing the bog, considering that i'm a mile high, I really don't see needing a large nozzle to get what I need out of the meth kit. I'm using my WW tank as a meth tank and the level is going down pretty fast considering that i've sprayed it about 6-8 times for about 5 seconds each time?? From what i've read here, it should be less?
One question that I do need answered is, do I have to be at WOT when spraying the meth? If not will this cause a bog.
Any more pointers you meth fiends can throw out, please do.
[QUOTE=frcefed98]One question that I do need answered is, do I have to be at WOT when spraying the meth? If not will this cause a bog. QUOTE]
I dont spray mine at WOT and it doesnt bog. If it is bogging, its getting too much.

Anyone??
Also, another question for you meth addicts--does anyone know how much power meth produces alone when injecting a normal size shot?
[QUOTE=fletchls1] Yeah kinda figured, I ordered up a M5 and a M7 nozzle to see what those do for me. Start real small and work on up.
I wish I bought my meth kit new now...don't know if the past owner tinkered with the pump output, or the meth controller. I was "assuming" it was out of the box new...but now I dont know.
I'll probably end up doing it all again(whats new huh) and buy a new kit if I can't get this one to play nice. I did take off my intake pipe and its not puddling up in there....so thats good, checkvalve is working.

what are the possible cons of running meth? if the system fails you just have too much boost for the gas youre running and havoc is had? what other concequences are there? is it bad so to speak for the internals? etc

For example, drive a full tank of gas without going into boost and you use no methanol.
Example 2. I did over 20 dyno runs at WOT and I used about a quart of Methanol.
Example 3. I average about a quart of methanol evry gas fill-up and I am mixing it 50/50 with water so I'm only using a 1/2 quart evry tankful of actual methanol. At $2.00 per gallon I'm paying 50 cents to run the equivelant of 116 race gas.
Hands down, it's the best mod you could do on a forced induction car.
