My RR results

[luke85]

Just been on the rolling road and Im looking for a bit of advice really. I made 250bhp from a calibra turbo engine at 1.2 bar of boost, the same engine last year made 290BHP at 1 bar so Ive lost some 40BHP. Ive upgraded the fuel system since the last time but the fuelling seems fine, 12:1 tapering down to 11.5:1 at the limiter. I put a bigger water nozzle in to help when I turned the boost from 1.0 to 1.2 bar and I think Im injecting way too much. The power starts to drop of at around 5k where last year it pulled hard to 7k and my theorey is that ive slowed the burn down too much with my water/methanol injection and need to try smaller jets, does this sound right to you people? Im using a 0.9mm jet now on the 2D system, fuel injectors are 4x470CC. From memory it was the 0.7mm jet I used last time. using 75%W/25%M

Graphs are below, 1st is power/torque at the flywheel, second is AFR/boost and power is at the wheels:
