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.
Nozzle cc's per minute

 Choose cc's minute from table above
% 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.
