Pre-Turbo Water Injection Works!

[MikeWarner]

Well, I just fitted a 0.3mm jet before my turbo with good results.

My ECU will log a fault code and cut boost if it sees over 20psi. I set my actuator to 20psi exactly and I've never had a high boost problem. After installing the jet today I went for a drive. The first time I put my foot down, the ECU light comes on and the boost is instantly cut.

What this tells me it that cooling the charge before the turbo does make the turbo more efficient. As I left the actualtor where it was, the turbo was doing the same work, but producing more boost.

This means you could run more boost without making your turbo work harder!

Nice!
