Methanol nozzle placement

[CajunKenny]

I've heard of people using windshield washer fluid from wally world. Is that really safe...what is the mixture ratio of that?

Second question: Do you have to switch the wideband to Lambda when injecting water/meth?

EDIT: I just read the whole right up and I see that the OP is running the washer fluid in combination with a bottle of HEET so it must be ok.

I will have mine set up with a inline flow meter wired into the ViPEC and running on a 4d map. If flow drops below a expected amount the ViPEC will drop timing and boost. I have not set any of that up yet but should work, looking forward to the challenge....ok I will get Bill to help.

Got a link to the details about the AEM check valve restriction? I just tried blowing through mine and it took 20psi of air flow to move some air through the thing. I couldn't blow any air through with my mouth at all! My turbo spools so fast I can't have any delay in delivery. Do you figure that AEM took this restriction into account so that at minimum start flow, the pump has sufficient current to flow right off the bat? I wonder if using a solenoid instead would have the setup flowing more that it's supposed to at startup? I'm hoping I can start spraying at 5psi.

Which flow meter are you going to run? I just ordered the Snow Safeinjection flow meter, as they just went on sale this month for only $129! Between the AEM's built in electric BoostSafe output, and the snow unit, I'll have failsafes up the yinyang

Kenny: After seeing the blue crusties inside my stock washer tank, I decided to either buy or mix my own proper pure fluid without any extra coloring or detergents that might be in washer fluid.

I was looking at picking up the the Snow Safeinjection flow meter, (and they just went on sale this month for only $129!) Which one are you going to run?

I'm going to try out.... http://www.labontemotorsports.com/store/ccp0-prodshow/VC-IFS-10.html

Its going to be hooked in to the ViPEC to cut boost when the flow drops, I am also going to have it drop timing as well as a warning light on the AIM dash, same for the low level warning.

Brad: It will hit pretty well instantly the pump is minimum 150psi.

Also, what is the approx. ideal Air/fuel ratio when spraying 50/50 Methanol/water? The article below says that the stoich point of gasoline is 14.7:1, or 14.7 parts oxygen to one part fuel and the stoich point of methanol is 6.4:1. http://www.srtforums.com/forums/f18...-fuel-raios-mixtures-latent-heats-etc-461354/

What would be the correct *volume* mix of 50/50 Methanol to water, if the mix is supposed to be 50/50 by *mass* and Methanol is about 74% the weight of water? Is it 1L of water to 1.26L of Methanol?

Put it on the dyno and see what a/f the car is happy at. Dont worry about the a/f # too much. The o2 sensor reads lambda, so rich on the gas a/f scale is rich on the meth a/f scale.

IMO run straight meth, none of that mix BS.

I thought the water helped cool the intake charge and actually helped a good bit. I'm running a fifty fifty right now, but I have five gallons of meth to mix up and I'm willing to try a different mixture or straight meth if it's proven to be better.

I've seen very successful results going both ways...
But I too, am curious as to which is better for the car/tuning, etc.
Or if it's just personal preference.

I stick with a 48/1/51 mix (meth/bug remover/water) as I use my washer reservoir as the tank and am not a fan of spraying a flammable mix over the car while driving

 

[CajunKenny]

IJ: Do the detergents or blue dye (if that's what it is) leave any residues anywhere? Chamber, manifold, exhaust...?

Something else I was wondering...do the people behind you smell a sweet windex type smell from your exhaust?

 

[IJ.]

Not that I noticed Kenny the Meth does clean the intake tract a bit if you're on it for sustained periods!

I had to trim the mix a little to get a ratio that wouldn't ignite on the floor.

 

[grimreaper]

awesome. Bug washer from hell on steroids. Need to turn the nozzles like we did in highschool to spray other peoples car at stop lights

Smells cool when you wash the screen

I mixed my own fluid for the dyno, but found a local auto parts store that sells the Snow Performance premixed 50/50 Boost Juice for a reasonable price.

Was able to boost up to 22psi/450rwhp on pump gas at the dyno yesterday

This is why I opted to leave the PCV plumbed into the throttle body

Nice Brad!

Can you post your dyno sheet so we can see your afr's and such?

What did you end up doing for a container?

I posted dynos at the end of this thread:http://www.supramania.com/forums/showthread.php?t=86561

I used a Snow Performance 2.5gal tank mounted in the hatch. Good thing too, I went through almost 2 gallons of fluid between several dyno pulls and drag racing.

Nice. Are you going to lean it out a little more in the higher mid range? It looks like you've got a little room there still. That should fatten up your curve a tad too.

So, I'm still a little lost on why the boost climbs so rapidly at first then tapers before the it rises again. It seems that the initial rapid climb is the abnormal part. At least compared to my boost chart. What's going on there?

EDIT: I think I found my answer. The SP valve you're referring to. Is that the one that aids in early spool like the diesels have?

Yep. The quick spool valve is doing what it's supposed to!

We actually made it richer around 5000rpm because that's were it was starting to ping at 23-24 psi with 2 degrees higher timing.

Its nice to see the results of an SP valve in action! Definitely on the list of things to own now. Thanks for helping me spend my money!

So, on your 50/50 mix...is that a mass or volume split?

I've read that methanol is about 75% the weight of water, and should be mixed by mass. But it would probably work either way. I just bought a case of the Snow boost juice and called it a day

This AEM kit has got to be the best $350 I've spent in a long time. It gets rid of all detonation below 20psi, so the ECU never has to pull any timing and the car just seems to have more power at all boost levels, even part-throttle at 10-15psi the car has so much thrust.

My experience of the car with:
- the 57 trim CT26 at 15psi "pretty quick"
- the new HTA3586r at 15psi "pretty darn fast"
- + water/meth at 20psi "holy shit!"

I've been following this thread for a while now and am really interested in putting some meth on my 1j, I have and AEM Ems and was wondering how I should go about hooking this up? I was going to build my own tank and was wondering if I should just buy the pump, and the flow sensor? And the nozzle? Is there anything else? And what size line do you use?
I am going to go do some searching on how to hook it up to my AEM, Does anyone have suggestions on this or experience?
Thanks for the tips and tekdeus your car is badass!

One more thing too, I saw Ian you were using 6x 100(cc?) injectors? By my understanding you can't just use normal ones for gasoline, where did you get yours?/What brand and did you see much of a gain from using multiple injectors or did you do it to make sure you get consistent amounts in each cylinder? And on your pump setup do you have a return line from your feed rail? Or do you use the motec to turn on and off the pump to vary pressure? Anything else I should consider? How
