Default Info on Effects of Water/Alky Injection

I want to know how much of a difference it makes on FI. I am building a 402cid with 9.25:1CR, large cam, and a F1R. I was told by a shop that with the largest pulley I could see 20psi of boost at 6000rpm. I am attempting to run on pump gas with this much boost. I want to know how much water/alky will lower intake temps or EGTs. I am trying to ask only guys that have done something like this.

The methanol also fattens up the mixture a bit. You could see about 40 to 50 degrees F in intake charge cooling with water/methanol.

Default .....

search cablebandits threads he had some good research on this. Note his results were also based on the nozzle sizing and pump flow and pressure.
