I did a little math the other day that kind of got my attention. I've always taken the Hp figure and divided it by the psi of boost to see how many Hp per psi of boost was being generated. It gives you an idea of the efficiency of the complete system.
The Corrected Hp output was 1108.6 with a max boost of 20.268 psi
1108.6 divided by 20.268 = 54.697 Hp per 1 psi of boost.
What is another interesting thing you can do is then use this to Guesstimate Hp at higher boost levels.
54.697hp x 25psi = 1367.42Hp
This thing is a potential monster, especially if at the same time the engine RPM limit goes up to around 7800 to see if it starts to nose over on power output. Talking to John he thinks I should have twisted it harder as the graph shows the power still climbing at the end of the pull at 7400
With you spinning it so slow, I’d say that number could even be conservative, as it’s not even in the meat of the blowers efficiency range. However, you would be above the recommended 18k rpm (pretty common, with few failures), but not by much.
