Water Injection in general and  RSR 1000 psi Water Injection Systems are outlined on our Water Injection Page.


Water Injection Calculator

Maximum water delivery should be in higher load low to mid rpm ranges tapering somewhat at peak rpms where load is less.Water or Water / Alcohol to Fuel Ratios are between 12.5% to 25%. This means Air to Fluid Ratios are between 11.1:1 and 10.0:1 with water injection. Enter several horsepower figures for mid range and peak rpms. Use our Boost and Airflow Calculator to see what your engine requires in boost to make a certain horsepower.


Enter Peak Boost
psi Maximum (Peak) Boost.
Peak Horsepower
hp Peak Horsepower at Maximum Boost @peak rpm. Set by wastegate.

% Water
percent Enter % Water. Enter 100% if you are to stay in the "Gas" class at Bonneville
% Alcohol / Methanol
percent Enter % Alcohol / Methanol. Maximum recommended is 50%. Enter 0 (Zero) if 100% water is entered

Typically you are looking for  12.5% at peak rpm/boost and 25% at peak boost at highest load in mid to past mid rpms.
