Thanks guys. I did this quite a while ago. The plan was to tune the 3 examples and present the other side of the story then change to the idc tracking kit and do it again.
Howeva my laptop has been giving me grief and finaly packed in and i lost all the data. i only have a very little data left.
I tried
Water
Methanol
50:50
10:90 nitromethane methanol
20:80 nitromethane methanol
I took a fully tuned meth map to the drag strip and smashed an uprated 2nd hand diff in second gear ( still managed a 13.0 @113 mph )
In october i took a fully tuned 50:50 map to the drag strip and this time with a KAAZ diff i cut a 12.0 @ 117 mph on full street tires running pump gas.
Howard what info do you want ?

I know it's off topic Scott, but I have a suggestion for you for a tuning/road laptop. Get yourself an Itronix GoBook off of eBay. I got one for about $200. It's a fricken tank. It's made for military use and conforms to all the US standards for that. Army guys use 'em out in the field and such. Touch screen, glow in the dark keyboard, real nice unit. Hardened everywhere, shock proof hard drive stuff, etc.

i didn't visit the links but the reasons i chose the 50/50 mix was because you can run higher boost safer with more of a safety buffer just like tuning to 11:1 as a safety net. if you figure in any inconsistencies with pure methanol since it is a fuel and if you tune it to 11:1 it can veer off course very fast if the AI is not delivering properly, with 50/50 even inconsistencies will only be half as drastic with your AFRs. next reason is the added benefit of knock suppression, while you will lose a small amount of power with the water in the mix you can run higher boost levels more safely to gain it back and then some.
i'm not trying to sway anyones opinions but that is just how i see things.

It worked ok. I never tuned with it but im unsure about what ratios rotaries will like. Its not like water of meth. When nitro combusts it goes twice. THose top fuel cars are really low compression ratio and run lots of timing fixed. Its a future project.
I am told it yeilds a very high power to percentage ratio

some is as high as 40% methanol, not quite 50% but close. there is MANY kinds of washer fluid so you will need to check the MSDS for each and find out its % of methanol if it even has any in it. only winter blends of washer fluid contain any methanol at all, generally speaking the lower the freezing point the higher methanol content it will have, the summer +30F junk has no methanol in it.
some people have used it with great success but after thinking about it i try to stay away from the washer fluid. why? because it has additives that can cause buildup on the nozzle, have you ever had a washer nozzle plug up with deposits? i'm sure most have seen it. maybe i am wrong but i just would rather use a clean water like distilled and pure methanol for my system.
definitely never use tap water for any AI system, over time it will leave calcium deposits in the nozzle and pump just like an old shower head with irregular or partially clogged spray patterns.

Nearly 14 months later, I will be revisting some of these concepts for my setup this season.
I am not willing to change my map and pull fuel to be used in conjunction with AI. (I currently have an old, manual WI system, and it has clogged on more then one occasion.)
My goals remain the same:
1) Run a non-tuned AI system.
2) Find the best mixture to reduce charge temps and knock.
I'm looking for a safety net above and beyond a nice safe tune for 93 pump fuel. Running a very nice map that is good to 20psi, and if I make it up to 17psi I want the engine to only feel like it's 13-14psi in terms of heat and knock. Willing to lose some HP by running straight water.
Hope to post some dyno's running different combinations of a mixtures...

Yes, I'd like to know if you're running a intercooler still.
It's getting to be about that time.......... for me to get a water kit. I guess I'll do a few nozzles on the comp housing.
