ultimate water/alky injection setup?

[fluff]

I know this has prolly been a topic b4, but couldn't search it out. I have a few people from customtacos.com, including myself who are wondering what is the best way to deliver water/alky to our motors. Aquamist, SMC, Sparco, DIY?

Also does anyone have results from spraying propane yet? Jay Carter's kit sounds good, but I can't find any results from the use of his kit. Is it better than water and or alky? Does it absorb more heat?

Thanks for any advise. I came here because I am sick of hearing speculation and I know you guys aren't going to feed us a line of BS because many of you use it successfully.

I've tried three different pumps and 3 different types of nozzles. Speaking from experience and reading others posts, brain picking, (from Steve Hill) etc., I like the following setup: Shureflow Pump, SMC Controller (for instant control), 4 Aquamist Jets (second stage fired by a Hobbs Switch) at around 17-18 lbs of boost, also have a NOS checkvalve on that stage, and run a 50-50 mixture.

Might be better setups, but finally I'm satisfied with the results of these components.

Thanks for the reply Turbo.

Is anyone running the propane yet? Would that be better than h2o and or alky? I'd think so.

Besides the fact that aquamist doesn't handle alky, has anyone tried out their system 2s? How much alky does it take to trash one of their pumps? Do their solinoids hold up to alky? That brain, the MF 2 looks good and claims 3D adjustability, but is it crap?

Thanks for the advise.

Another DIY-er here. My setup is similar to the prior message. I use the Shurflo, with Aquamist, and two-stages. I also use the Shur-Flo accumulator which works nice too.

I think the ultimate system is the one that meets your presonal needs, since its easy to get very sophisticated with these setups (from simple on-off controls to SMC to 3D mapping in an MF2). The nice thing about water alky is that almost everyone who has tried it has good results, regardless of what system they use.

Im curious, clearly alot of you guys seem to prefer the Aquamist nozzles. But, you seem to prefer a Shureflo pump to the Aquamist pump. What is the reason for this? Im currently using the Aquamist pump, and it is developing over 75 psi with each nozzle Ive tested with, and use, which are the .7mm, .8mm, .9mm, and 1.0mm. Ive tested them all with regard to delivery rate, and to water pressure , and theyre fairly close to spec.

By the way one thing which confuses me is that alot of the guys not using Aquamist nozzles are using other nozzles with gallon per hour flow rates. Ive converted the 10 gal per hr flow rate to CCs per minute to compare with the aquamist nozzles. 10 gph nozzles, in ccs per minute, would be about 21 oz/min which is about 597 cc/min. The largest Aquamist nozzle, the 1mm nozzle, flows about 330 cc/min. Since so many of you are using multiple nozzles, I would think the non-aquamist nozzles would be better for you since they flow so much more; the 10 gph size flows almost twice as much as Aquamist's biggest size!

And, why do you prefer the shurflo pumps? Which one? With the smaller Aquamist nozzles, like the .4mm nozzle, the aquamist pump is rated at over 150 psi! Do the shurflo pumps create even more pressure? The Aquamist pumps and nozzles are rated together, ie, the pumps rating is always in terms of a particular nozzle, since a different pressure is measured with the different sized nozzles. From what Ive seen of the shurflo pumps, its not done that way...So, how do they rate their pumps pressure?

Thanks.

Fluff,

I'm running propane and water/alcohol injection. I went with DIY H20/alk kit (thanks Steve Hill! ). Good atomization is the key. Aquamist makes a super nozzle for this, also look for nozzles that can produce a fog as opposed to a spray.

I like the propane, but I don't think I'm going to take out my water injection anytime soon. Both serve their purposes.

You guys with the SMC kit...Do you know what model number shurflo pump youre using? ON the two stage setups, are you using an accumulator to store the pressurized water, and a solenoid valve to release to the nozzle, controlled by a pressure (hobb) switch? And, what shuts the pump off after filling the accumulator?

Boostm3,
I don't think any ??? are using a storage accumulator with a Shurflow or Flowjet pump. They're rated around 100psi at way
more volume, than we'd ever use. I think they're basically a bildge pump used on boats???

The solenoid is used so it will only open the second stage when the hobbs switch is activated. When closed the solenoid also holds the liquid in the line. My lines are only around 1/8" in dia. (4 lines) so when they are hit with 100 psi the spray is immediate.I think the early kits used a pressurized tank and most found that the plain old deadhead (Shur. or FlowJ.) worked at least as good or better with less maintanence., especially when they could provide high line pressure combined with massive volume.

I forgot that my brother used the Shurflow and I have a Flowjet on mine. It's a monster (about 3" dia. X 7" long) and I have it mounted down on the driver's side frame near the charcoal cannister.

I can't remember the #, maybe someone can chime in.

If I come across the paperwork, I'll post the #.
