You have a million dollars and must be spent on a water/methanol system, what kind of specifications would you like to see.

Happy new year to all from Aquamist

 

plug and play

 

After some 50+ views, it appears as far as the end user is concerned, an ideal system is a "plug and play" variety.

As a one of the many WAI manufacturers, we agree totally. Possibly the next "what if" question is what kind of delivery system you prefer if money is an object. I will put a list below reflect the options available currently.

1. on/off system ......... non linear with input $300.00
2. PPS system (also known as PWM Pump Speed) .......... non linear with input signal $400
3. PWM valve (as in the conventional fuel injection system) ......... linear with input signal $500

Given the the cost difference between the systems ( progression) is around $100 and on one has an unlimited fund allocated for a WMI system. As a manufactuer, we would like you to help us with this question:

Is $100 is deciding factor when you pick a system, without comparing the system performance?

 

ive been running the aem meth kit for the past few years. what is the lifetime of all these pumps? mine is mounted in the trunk and sees all types of temps from summer to winter. i dont use it in the cold but its still back there. i try to empty it in the fall and fill it with pure meth to keep the lines and pump from freezing up. what do you recomend for temp changes?

 

You are one rare user that realluy look after your systems. The work duty of the pump is quite light, so it should easily out last the car.

What pump is it? Shurflo or aquatec
Mixture? water/methanol ratio

 

its old so id guess the shurflow. i run 50/50 .

 

Shurflo has been known to be reliable below M50/W50.

 

I think you will find two different kinds of consumers..P-N-P kits may apeal to some people but not all. For me, most of the fun is in the installation & dialing in the system. I would rather do the wiring & install things where I want them rather than having a generic wiring solution.

Of the three types of systems the PWM valve would be the best, $100 between systems isn't enough to sway me either way, when I'm looking for a system I'll find one with the key parts I want & change up the rest . Right now I'm in the process of upgrading my PPS system(SMC) to a two-stage PWM valve system based off a DDS3 v10...After pricing all the parts & plumbing I might as well be spending $1 million

 

Over the years I have experienced the same attitude to modification work. Some enjoyed the entire journey but some just like to sleep through it.

There are also two types of end users. Some would do indepth research and the other just goes for the bottom line.

The DD3v10 is full time precision flow controller. If you add a pump, a relay and an inline valve, it is a complete PWM valve system with dash gauge and failsafe. Not many people realise its capability. But only suited to those prepare to put some hands-on effort to make it happen.

 

So after running the AEM Meth Injection with Injection Monitor, I would say that is a great system. Even the most recent Aquamist stuff is really awesome. I think that it is all a mute point. It is still a secondary fuel system that is not built like a legit fuel system.

For me I would prefer 4 more fuel injectors and a second fuel system, and when my ecu got to a specific load it would switch the pump gas injectors off and cut 100% to the Methanol Fuel System.

Most standalones support this already, however I think that is the best way to do meth injection. Short of that E85-E98 is the best option.

 

From the birds eye view of the entire wmi market we sometime wonder if it worth putting so much effort into improving the precision and quality of a delivery system for this market.

It appears only a small proportion of user understand the importance of linearity of delivery. If a progreessive system delivers 0-1000cc/min between 0- 30psi, what is the expected flow at 15psi?

How many people would expect the answer to be approximately 500cc/min?

 

After talking to Jeff Howerton, I think a PPS upgrade kit should be considered. I know that one of your kits used 1/4" fittings, but a recirculation head from the old 125 shurflo, or the newer 160 aquatecs, plus electronics. Buying a used HFS-3 or 6 is gonna run $500-$700, and a used PPS kit will be $100-up. A kit to convert a PPS pump and hose/fittings/nozzle to a PWM-V system would get people to the Aquamist camp faster. There's an HFS-1 for sale on here, and I am only a few steps away from buying it, sending the DDSv3-10 to Jeff for resoldering and using a HSV I picked up also to build a ghetto "HFS-3". It would be much easier to just buy a kit to convert stuff over than having to piece it together.

But to answer your question strictly. Vishnu for my vehicle. Gauge with a real fluid level. F-E, or actual amount. Built in failsafe that does what the Tephra map does. Software that runs with the ECU, and injects based on actual requirements from the ECU. Ron Popeil style set it and forget it.

 

On a PWM Valve system, I would think/hope it would be close to 500cc

On a PPS system, no way

Keep building and improving those wonderful products

 

I believe all shurflo pump can be converted to a "pulseless" system, just need to purchase the pump head, set you back about $50.00. Opt for a 125 psi spring if you are goiung down this route.

I too have spoken to Jeff, the PPS-PWM system conversion is quite straight forward because the DDS3v10 has everything to drive the a FAV (fast acting valve) and pump (via a power relay).

As long as you have a HFS-1 with DDS3v10, you can easily change it to a PWM valve system with one solder link. May be changing the MAF to a FAV (if you are critical on dynamic range)

 

A well set up aquamist PWM valve system can hold linearity within 2-5%. This translate to 475cc/m to 525cc/min. We supply <2% systems to fuel cell companies.

Make a guess:
A PPS system flows 500cc/min at what %dc? 25%, 35% 50%?
