Thanks Joe. Share if you care is the moto...remember?Impressive work Themis! Thanks for sharing all the data, makes for some interesting & informative reading. I'm currently running progressive boost on mine too but will have a play on a dyno in the new year to see where it's happiest. I love your boost setup for track most of all, curve looks ideal! How far do you think you can push the limiter? Is there a reason you chose 7300 RPM?
Limiter is ruled by the engine internals. I’ve got nothing to worry about at 7300rpm. If I want to go above 7500rpm I would add stronger valve springs, different cams etc. But I think there is no reason to do so. The turbo might not like it too, as it will lose its flow at higher rpm. Now, if I had got a big turbo like yours then I would consider to go higher and take advantage of the better flow of the turbo at higher rpm. If you see your power-torque curves, you’ll notice your torque curve is still climbing till your rev limiter. That’s exactly an indication that it is willing to go higher!
