ok so i did the math on the link u posted for finding out what size nozzles to run and i came up with 2x .8 nozzles. this was calculated figuring the 165psi pump for the hfs6, my 880cc injectors, 30psi peak boost, on a 50/50 mix. does that sound about right or did i miss something

Yes the DDS3 has a power button on its face. When off or error occurs it will switch to the alt map.
The Aquamist kits uses jets and the link I posted for jetting calculations includes both jet size/flow and basic nozzle size/flow as well. I would think that it would be based off more than just Hp. Some use it simply for knock supression others as cheap race gas.

For % replacement of fuel basic rule of thumb as follows...
100% meth ~ 25% of fuel
50/50 m/w ~ 15-20% of fuel
100% water ~ 10% of fuel
esevo knows alot about WI I wish he would chime in...
Are you calculating in IDC as well?

You have to subract your boost pressure from your pump pressure when reading from the flow chart. I use 100% meth for ease. No mixing required

Sounds good to me. With the HFS - 3 or 6, you can step up the gain to increase the IDC slope of the jet. It is also very easy to add a larger jet if needed. I guess the larger injectors threw me off. I thought the jets would be bigger, but you are mixing water in.

Good info. Looks like the nozzle I have is a little too big for my setup but it works. Looks like I should be using 2 nozzles instead of one. Where should one mount 2 nozzles? I have mine between the i/c outlet and the bov right now.

Using 100% methanol can corrode the connections over time. The older style shurflo pumps were prone to leaking. The new Aquatec pumps have a greatly improved design which seals the pump head extremely well. People have been running them for years with no leaks now, so I have heard. The only other place I got a leak from was the quick connect fittings. I had to replace them all with compression fittings. The new kits come with compression fittings for all connections. The only one you would have to order is the little T fitting for running 2 jets. Gasket maker can be used to seal the pump or any O-rings that give out, if either ever occur.
Good call on the jet location.

I wonder if a 50/50 mix will burn? I put some 100% in to a empty/clean cat food can and they dont lie. Methanol burns clear and colorless. The only way I noticed the flame was from the heat bending the sun light in its shadow. I could not even tell it had been lit. Sure enough though if I held a stick over it, the stick would start burning.
That is also why I opted for a FC from Howerton Engineering. It is much easier to fill, has a vent line with a built in check valve to prevent spillage upon flip over, contains baffles to prevent sloshing, has a protected inner tank, and is bolted to my truck. He also offers two tank enclosures. Getting rear ended on that side would suck but it makes me feel better about it.
It is ok to use a little larger nozzle. I calculated to use a 1 and .8 but I am going to step it up a little. You can easily tune it out. The only time that it would become an issue is if you start pooling. When I was over jetting and I changed gears my afr would drop to 8-9 and stay that way for a second. If I went straight into the next gear and got back on it. The afr would stay in the 9-10 range and drop again in the next gear. My old tuner was dumping it in. I figured it out when I bought a wide band and started to learn to tune.
