Measure your blower pulley.If I recall, the supplied pulley is 3 3/8", which KB refers to as 6psi. It yields 8psi on many applications including the one I had. If indeed you are only at 6psi at your wot shift point, then your hp/tq numbers may not be too far off.

these are the two best alcohol kits available. dont waste your money on water injection. go with alcohol

 

Actually, the optimum mix is 50/50 water/methanol. Straight water is grea too, as is straight alky. Mix em and its perfect. go to www.turbobuick.com and go to the alcohol/propane forum. Its the best one on the net.

To add to the benefits of using Water/Alcohol, my brother-in-law, who works as a consultant on the University of Idaho's Future Truck Project, tested the use of water/alcohol injection on a six cylinder diesel engine and determined the best result was 13 percent water/alcohol by weight/volume. I'm currently running 7.28 percent and running well; I don't know if adding more will help me or not. I'm using about .006584 Gals./Second (.06584 gals./10 seconds), 1.5 gals in 3.797 minutes; this is all at WOT. I use about one windshield washer tank for every two to three tanks of gas.

My setup is homemade, using a 60 PSI Surflo ag pump, 30 AMP relay, two mist nozzles (10M and 15M), tank level sensor, in-cab-light level sensor, Hobb boost switch (set at 4 PSI), etc.

The setup cost under $200.00.

 

Seems like if anything else the water/alcohol injection is a good piece of security.

Anyone experienced with the hand-held PMS programmable engine management systems?

 

Here a link to a Water Injection Calculator

According to the above website they recommend using denatured alcohol, not methanol. However, I thought that using Denatured alcohol is not a good idea since it contains Kerosene which can be bad for the engine.

 

RayCee.
Before running any Alcohol mixture I did research. I found nothing negitive about denatured, but found negitives on meth ie being corrosive and hard to find. If you have a link on the negitives of denatured I would like to research it better.

Thanks

 

denatured alky is the best substance you can use for injection

 

I beg to differ. Methanol is the most used, and highest performance from what I have seen. Denatured has kerosene in it. Try to clean your windshield with it, it smears. Methanol evaporates clean...

Methanol is not going to add any horsepower,it is going to do the same as denatured alcohol allow you to add more timing without detonation for more power.I like denatured alcohol better because the "kerosene"content adds less cylinder scuffing than methanol.There is a site called gnttype.org that can answer all the questions about alcohol injection.It even has links about how to make ur own kit.When i ran my regals I put 90% isopropyl over the shelf stuff from a drug store.I got it for $0.99 a gallon from CVS pharmacy.Denatured alky was around $2.99 a gl. from lowes,I do not remember what methanol cost but the isopropyl and denatured stuff was alot cheaper and could not tell a difference.I tried the 50/50 mix and did not like it at all.Try to go as high as possible in alky content as possible.Just be sure to keep the alcohol tank full at all times,when one goes empty you WILL be getting a new engine.

 

Another plus with alky injection is the intake track,intake valves and combustion chamber will be as clean as new after 100,000 of driving because the alky cleans them every time it injects alcohol.

 

thats exactly the information i was passing along.....my GN buddies use denatured and nothing else.....if its good enough to run in the 10's at 25# boost on a GN, then its good enough for my slow truck.
