End of October the engine was put back together and mounted in the SDM's engine bay again. The new engine started without fuzz, sound was different from the first engine and idle rougher. About a week after mounting the engine SDM went on the dyno. Unfortunately no pictures of the dyno session itself because I was occupied with setting up the engine. Compared to the stock engine the torque up to ~3000 RPM is pretty much the same but after hat the engine is becoming stronger. At first we used the 7K RPM redline but it showed the engine was cut in the middle of a good powerband. At the end the limiter was set at 8K RPM at which point it showed the power was slightly dropping. I think the limiter will be set to ~7600 RPM for it's usage. Power was hovering around 230 HP at the crank during the final adjustments. Torque was near 230Nm over a wider area. End of the day we settled for a peak 240Nm torque near 5800 RPM and 231 HP near 7300 RPM. Since I was only aiming for a ~30 HP gain over stock in this stage one can understand I'm more than happy with these results. |
