I used a water injection system on a triumph Trident that required 97 octane fuel; 13.5:1 compression out of the factory. With a water injection system, I could run 93 octane gas and pull the timing back about 10* to keep detonation to a minimum.Up until about a year or two ago they had a website. I bought my El camino Gas tank from them. now it is carparts.com. Anyone else buy the water injector that was supposed to give you more horse power buy cooling the intake down.
