AL just curious, do you find these kits to outperform the buschur kit? I never really looked into the aquamist kit but it looks to be pretty good after reading this review. Let me know what you think as maybe I'd switch over.

 

I think you are missing the point all together

That is like asking me if I prefer a Chevy Cobalt to a Porsche Turbo

There are varying levels of complexity, engineering and material quality in any product

The Buschur / SMC kit is a very good unit and it performs flawlessly and will work very well. It also comes almost fully assembled. However, it does utilize a very primative method of adjusting the flow of alcohol - the flow rate is based on a map sensor with a progressive duty cycle applied to the pump. The more boost the more alcohol. One of the problems it has on the trunk mounted units is a signifcant delay in the delivery of alcohol from the trigger point as the pump is off until a pres set level of boost as the pump is in the trunk it takes time to build line pressure. There is no fail safe. It is a kit which can produce great results and it has worked well on many cars. I also wrote an article on that system called "The Ultimate Cheat" in Turbo magazine. I also used to run that kit on my own Evo 8 with great results.

The delux aquamist kit is a vastly more advanced and complex unit. It costs a lot more and also will take more time to properly install and as such its not really comparable to the Buschur SMC kit. No more than a Casio watch compares to a Rolex.

As I have explained above it utilizes a high speed valve much like a fuel injector to control the alcohol in a very fine and precise manner in relation to injector duty cycle which is a much more useful load reference than boost - (for example we know that an evo requires more fuel at 6,000 rpms and 20 psi than at 3500 rpms) which is why an injector duty cycle based system with a high speed valve can deliver a more accurate proportion of alcohol to match the needs of the engine at any rpm and load point.

Further since the pump is already running - holding a constant 125 psi of pressure in the line (due to the on board custom accumilator) - when the valve starts to open the spray of alcohol is insant.

Finally - there is a very adavanced gauge monitor and fail safe which is invaluable.

Honestly in the end comapring a $500 Buschur / SMC kit to a $900 Aquamist kit is silly as they are really not even in the same leauge.

Not everyone will be able to afford or justfiy the investment in a system of this nature - but it is nice to know that such a system exists for those who want one.

The duty cycle is going to be 0 - 100 no matter which injector you have

If you run too large and injector and say your max duty cycle is only 50% instead of the normal 85% (which is what most tuners advise) then you would compensate by running a larger injector in the alchy kit

The kit would still adjust the flow relative to the change in duty cycle - you would set the starting point a bit lower.

This pump can support up to 10 or more nozzels so the over all flow rate can support a Viper with 1,400 whp or as small as a lawn mower if needed

buschur/smc kit + [good failsafe] = $500 + [~$300] = $800

aquamist hfs-5 with 1st class components and intergrated failsafe = ~$900

very resonably priced IMO

 

Wow, Al recommending a non-Buschur product? Has hell frozen over?

 

I still recomend the Buschur / SMC kit it has a valid place in the market for customers who want the benefits of a simple yet crude easy to install kit with a lot of performance potential

I greatly prefer the Buschur / SMC to the Snow and Boost Cooler kits which have overly large gross flows of alcohol which are like converting your car to a crude mechanical fuel injection system

If a customer is on a budget and wants a easy to install simple cost effective alcohol kit backed by a great warranty the Buschur / SMC unit is a very good system for its price point. It can produce amazing results.

With that said - this new aquamist set up using a modified sure flow pump has moved aquamist into a new realm of superiority - its not even in the same sport as SMC never mind the same ball park.

The previous aqua mist pumps were simply too small and the flow capacity not enough to fuel my passion for power - also the pumps were not rated for 100% methanol / ethanol

This situation was corrected with the new series of ultra high flow sure flow based pumps with accumulator. This system can take care of any evo from a stock one to a 1,000 whp car like mine.

I am not a subborn donkey - when I see a new and improved concept I am open minded and willing to keep an open mind. The reality is that this set up is the best available system on the market and I always gravitate to the best products available. Don't worry there are still many great Buschur Products left for me to buy and recomend.

 

This aquamist kit is amazing but just like anything else it needs the right tune and Al tuned my car pretty f***ing good. It pulls hard and is a very fun street car to drive.. Thank you Jimmy, Al , and all the guys at The Shop for taking the time to install the pain in the a** system .These guys were there till 2 in the morning making sure everything was right.. I don't know if they need the business(cuz it's really busy there) but every one should check The Shop out . Just don't smoke near the doors , Al will try to kill you... jk

 

This isn't really how the system works. The pump has a check valve in it so that once pressure is built, it will hold the pressure in the lines even with the pump off. The accumulator smooths out the normal pressure fluctuations due to voltages changes, etc. plus it provides a reserve for pump start-up. This is the reason that the Aquamist has an output that won't trip until the flow sensor measures flow. In other words, you are supposed to have it set up so that once the flow comes up and the flow sensor measures it, then the aquamist trips the output that switches to a higher boost level, adds more timing, etc. If you think about it, being that there is no pressure regulator and no return line to the tank, there is no way the pump could keep running if the system wasn't in use... where would the liquid go? The pump would be under an extreme load and the pressure in the lines would be insane.

But besides that I agree 100% on two far more important points:

a) no other manufacturer of water/alky kits can match Aquamist's completeness and quality

b) no other manufacturer of any type of part can beat their customer service. Richard and Jack spend at least 25 hours a day answering questions on forums and helping people out -- even people who are using their competitor's kits!!

 

Hmm im wondering were he gets the modded pump. Ive been running mine now for 4 months. We get them direct and use a 3 gallon tank also Al. I would say it pushes about 200psi under wot

 

the 150W aquamist/shurflo pump on the HFS-1/HFS-5 system is custom made in shurflo factory according to aquamist specifications. This bypass mode pump has 3 internal pressure regulating valves to keep pressure at 125psig - it can run all day long w/o any issues.

the pump stays on for the entire duration of the injection event - the accumulator evens out the pressure pulses from each pump stroke resulting in a pulseless flow of water/methanol.

the accumulator also "stores up" injectant pressure, ready for the next injection event. the system is always cocked and ready to fire.

Left: Aquamist bypass mode pump with accumulator + High Speed Valve system
Right: On-demand mode pump system used by the rest of WAI maker

note: the lightning quick response and pulseless/rippleless injection of the aquamist system

SlowCar,

You're right about the pump. Now that I think about it for more than two seconds, there would have to be some kind of internal bypass valves otherwise the pressure would be all over the map as the HSV's duty cycle went from 0 to 100%... But the main point I was wanting to hit on is that the pump does not run 24/7 while the car is on (even if it would be capable of doing so without damage) but rather it turns on and off for each injection event. Please comment if that is not the case, but as far as I understood, Richard confirmed that is how it works.

 

Its rather complex to wrap your mind aorund the workings of the genious engineers at Aquamist but I feel you will agree that it is richly fascinating the manner in which they re-wrote the play book on alcohol injection.

It is a world class product and they - Aquamist are stocked with passionate and intelegent professionals from top to bottom, truely a world class operation.

aquamist in the last VIII
aquamist in this IX
X.....they will be aquamist in there too

most of the components on my IX was transfered over from the VIII except the high flow pump
