Hi All,
ronbuick convinced me to but into your ethanol conversations due to my own experiances. I am the guy that works for an ethanol producer in Idaho but that in itself does not qualify me as an ethanol expert, but, I have 7+ years experiance drag racing with ethanol. Sorry to correct you Ron but my current ride is a turbocharged Hilborn injected Kawasaki and my friend has the turbo H-D that runs 7.70's. My best so far on the Kawi is 7.06@200.5 wit a bunch left.
Thats about enough horn tooting, I feel I need to reply to some of your spark plug questions. With the boost levels you all seem to be using I would stay with the stock heat range unless you absolutely feel they are causing detonation(Highly unlikely).
There is absolutely no validity in E85 or blends causing preignition, there is no such thing as ANY pump gas that will out perform E85 in every aspect. By using ethanol you WILL decrease chances of preignition due to the increased MON+RON octane rating not to mention the superior latent heat of evaporation(Intake cooling effect). Which you all know is a big plus when the boost levels rise. I do not use an intercooler with 40 or more psi of boost, I inject fuel at the inlet of the turbo when boost reaches 20psi to produce the same effect as an intercooler. I could go on and on so if I can help in any way please feel free to ask

Pablo,
By the way the mon+ron octane rating of E85 is 103. Octane ratings are only one way to rate a fuels resistance to detonation. Alcohols excellent latent heat of evaporation in itself is a deterent to detonation that is not a factor of mon/ron. You also have to consider flash point and vapor pressure to compare apples to apples. Alcohol in comparison to Gas in any form is a more dificult fuel to ignite and this is why your ignition system must be up to the task. Go to any race fuel supplier and see the list of how many types of gas there are compared to how many types of alcohol. No matter what type of motor or induction an increase in static compression is needed to take advantage of the benifits of alcohol.
