here is an email i got from Jeff Howerton about IDC i found interesting and pertains to the thread

" unless your IDC is very low, 50-60% range, since the Aqumaist tracks your IDC it's all relative. So if you are at 70% or 90%, the system matches your IDC so it will be fine"

Jeff said i would be using the 4 port bar for splitting off for the three nozzles since its a compression fitting and better suited for the 100% denatured alcohol

 

I found that since I was at 70% IDC at peak that I had to add some gain back in to help compensate. I said screw it and put in the two 1mm jets. Now its back to tunning and having enough is not a problem.

I was going to purchase a 4 port bar but they were not ready, when I put my kit together.

Why denatured alcohol over methanol?

 

OK jeff explained it to me I was making it too complicated. I was trying to add the IDC comp back in and you don't need to unless its really low like you said. Also the step in bold was to add a little back in due to mechanical losses due to setup...

 

I will have to look into the snow performance to give you a good answer. I would see if you could run two nozzles that would equal up to about the same spray as the individua nozzle. This would definetly give you better and faster atomization. I am assumeing that the kit is progressive. Some of those can take time to build up pump speed and it may not have time to build up flow as you stated.

 

yea i just followed all the steps on the site

easier for me to get my hands on since any home depot or lowes carries it and just as effective

 

Yes it is progressive. For next summer if I dont go E85 I will go to 2 nozzles. I also want to get away from the progressive crap.

I may be wring, didn't you have an aquamist HFS-1 before?

 

I have that as my failsafe only. You helped me in the past with it

 

Which version # of DDS3 do you have?

All DDSv8 on has an output for powering up an inline valve. Putting an online valve to your existing system might help retaining some line pressure. All PPS systems run on a bit. Why not use it to your advantage. Allow the "run-on" to pressurise your system rather dribble fluid into your intake.

 

Not sure what version. I think V10 if that makes sense.
I have a check valve to help dribble. I think ill just have to have this control everything and get rid of the snow performance controller.

 

If you have a v10, you can turn your current system into a fully progressive IDC system by adding a fast acting valve, the v10 has an internal IDC to FAV converter.

Preferably, your pump is a constant pressure, bypass type set to 125-160psi.

 

I might have to do that for next summer. I have the new style 250psi pump but it has the push in style hose fittings. I would also need the adaptor to hook up that FAV. Does it open the inline valve based on IDC then?

 

First of all, I need to know the exact version of the DDS before advising turn your system into a progressive IDC system.

The 250psi pump will not work well with our system because:
- Rate of tempearture rise on the pump is too severe for a constant pressure system
- The line pressure is too high for our valve to work effectively, dynamic range will suffer.
- You need to change the by-pass spring to reduce pressure
- At 160psi, our valve can deliver in excess of 1500cc/min. More than enough for two jets.

May be we just leave things as it is.
