Buschur made me an Alcoholic !!!!! Dyno results
I was wondering if the maps you guys have made (timing, fuel) are identical or how far off from c16 maps. I have my car tuned for 94 and then on c16 which hits about 25psi and tapers to 20psi. Just wondering if I can use the same c16 map and run alcohol on 94. that would be sooo nice.

You can use methanol, it is about 1/5 the price of denatured alky but much more corrosive. It will kill the pump much quicker then DA, Dave did say at some point they might have an all stainless steel pump out then methanol might be a better choice.
I have had the system in my car for over 2 weeks and even with the testing have only gone through .75 gallons.

AL: Im going to be looking for a tune with the booze shooter sometime in the near future and was wondering as to what your schedule is going to be over say the week of march 5 - 12?

If you want one of these kits I would get your order in soon. The comapny that makes them is small and I think they will be back ordered very soon.
For AL or anyone tuning a H20/alky kit
Has anyone dynoed and compared a 100% water injection to a 50/50 water/alcohol?
I would like to see the 100% water results. Water has a higher latent heat of vaporization than alcohol does, providing better cooling and knock supression than the 50/50 mix. But I'm not sure if that offsets the additional fuel/octane from the alcohol or not.
I personally would want to run 100% water, especially where long runs under boost are concerned or any time where temperature control is a must to prevent detonation.
Anyone have any data?

You're correct. Water has nearly twice the latent heat of alcohol. However, it seems that there might be some debate with regards to the knock suppression capability of a 50/50 mix versus 100% water. I've read that the 50/50 mix is even more effective than water, probably due to the high octane fuel content of the alcohol.

Also, some sage words of advice from the above paper:
The system I'm installing will pull boost and throw a warning light in the event it detects a reduction in water/mixture flow.

Also, some sage words of advice from the above paper:
The state of your air/fuel mixture and timing after performance tuning for water injection or mixed methanol injection will be more than sufficient to destroy your motor if the water injection fails while under load. The responsible user will take measures to ensure adequate water is in supply and flowing during high power usage. Ideally along with a fail safe that will cut boost if a fault in the system occurs. At a minimum warning lights for water level, water pressure and water flow should be employed. Ideally triggers that close all boost solenoids in automatic response to faults would be employed by high end systems.
