"100 octane is not very expensive" Over $ 6.00 a gallon is cheap ??

 

Yup tell me about it. Next year same time i will be on my way back to the east coast where 94 flows like rivers. I cant handle 91 anymore.

 

94 is becoming rare - only in NJ now?

93 will be on some trehuggers hit list next year

 

110 leaded is $3.99 here.

 

damn 100 sunoco is 4.50 gal here in Tampa....

What the hell is water injection guys? Sorry for the maybe dumb question, but I have never heard of this...

last tiem I checked water wasn't flammable!

 

It drops down yr intake temps so that helps the tuner alot. they use it on most WRC cars. You can find alot of info on the net about it.

 

Hey that what i found on the net

Why Water?
I could bore you all day with scientific theory and all of the information that I've found, but I won't. Plain and simple it works. It's been used for a long time with many great results. Probably the biggest automotive community to embrace Water/Alcohol Injection is the Turbo Buick Grand National camp. There are many documented how-tos and detailed explanations on theory of operation and results.
For a quick overview, here is an exerpt from Steve Hill's document titled "Water Alcohol Injection"

"Water Injection, or water/alcohol injection, acts as a highly effective gaseous intercooler. The only reason for an intercooler is to cool down the hot, compressed air from the turbo. Water can do this job far better because it has a very high property of Latent Heat of Evaporation, 500+ BTUs compared to gasoline's 135 BTUs and alcohol's 470.

If you need an extra bit of fuel, a 50-50 ratio of alcohol to water strikes a good balance between the maximum anti-knock capability of water and maximum supplemental fuel."

If you search more you will find ton of info about it

 

Thanks! Az3ar...

 

Unocal has 100 octane in San Jose for $4.29 gallon. Wow, finally something that the Bay Area has cheaper than L.A.

Lamb, try running Shell 91, I think that crap is worse than most stations 87.

 

Exactly! I know a lot of us west coast dwellers would love to be able to tune on 93 or 94. The 91 **** gas out here is crap!

 

But since liquids don't compress the same as gases, wouldn't this cause cylinder pressures to skyrocket?

Sorry for the stupid question, I don't know much about water injeciton.
