I heard you mention this a few times, yet the wideband only sees the average of the 4 cylinders and does not “show the feel”

Everytime the “on-demand” type alky injection pump switches on/off, these happen:

-pressure changes
-flow changes
-atomization/size of mist/mass of mist changes
-distribution in each intake manifold change?
-AFR/octane/cooling due to latent heat of vaporization changes due to possibly uneven air/water/meth mixing
-combustion rate in each cylinder vary due to the effects from above

could this explain the “feel” you are talking about?

Left: aquamist/shurflo pulseless by-pass pump
Right: regular shurflo general use pump used by all other wai manufacturer – aka pulsing pump

Wow Abner, you are the man. Thanks for that video, it's nice to see you take the time to do these testings for the evo community. Awesome test!! I'm just glad I did it right the first time. Aquamist

 

By the way, what size nozzles were you using there??

 

both the setups use Hago M5 nozzles

 

holy wow thats sweet. im glad i got the HFS-1 kit.

 

Your video needs music. Your the only person I've seen that owns their own hood.

 

FYI, our S-HSV kits do not pulse.

Here is a video of our S-HSV kit against our closest competitor.

i think your video shows comparison between progressive pump speed injection vs. High Speed Valve injection.

the video i made shows comparison between aquamist/shurflo "by-pass" injection pump vs. shurflo general use "on-demand" injection pump.

 

nice vid...

You are a brilliant man and also a man who is driven to explore reality as it is - not how people represent it to be.

As you know users who use methanol or ethanol injection substitute anywhere between 5 - 20 % (average user) of thier fuel with the alcohol injection. In effect what is going on is that a modern EFI (electronic fuel injection) is being replaced by the crudest and most primative form of mechanical fuel injection. The greatest advancement in power production per volume of engine displacement have been made through the inhanced capacity of modern EFI systems. Look at Porsche turbos and how much power they pick up by removing the old school mechanical fuel injections and installing EFI systems.

Some of these alchy kits I have seen in use are so crude its amazing. It is no suprize that many "innovators" in this field focused initially on large disel truck applications.

I have stressed that users should attempt to run the alcohol as a tuning aide - not as a means of primary fueling as the vast majority of alcohol kits are very crude and simplistic.

The system on the right in your video is not only crude and inprecise it is also pulsating and oscilating which will result in a car which has a rough "feel" Of course the extent of the effect of the effect on the feel of the car is directly related to the proportion of alcohol you are injecting.

A system like the one on the left will make the car not only feel better - it is just better from a matter of theory and design. Obviously, it is better to have a seemless and smooth even spray. Even better obviously when you have something like a high speed valve metering the flow rate in a very precise manner.

abs,
your a fuggin guru!
wow!
you are the bomb-bi-zee baby burb

 

I thank you and Nick so much for making me hip to this meth kit!! man! I almost got a smc kit

 

HOLY SMOKE BATMAN.........I mean Abner. That video just says it all.......I really damn happy I went with the Aquamist HSF-5.

 

if the other kit dribble at the end , what ill effect can it contribute to engine?
