Update with labbed prop, ran 87.6 gps, with gf, me, 3/8 fuel. I didn't realize it but for my setup every 120lb added to boat I will lose 1mph, so keep this in mind when testing props.

82predictor. Yes original dyno was 704hp at 5250rpm. I was only able to run it for about 2 hrs before the plugged oil line in the procharger burned the compressor up......I had a 26p Bravo then and could only get 76gps (and I was happy with that) I sent the compressor back to ATI and bolted it back on after a complete rebuild.....and wow did the engine wake up! I had no trouble over-revving the 26p so I bought a 30p and spun that beyond where the HP was made on the original dyno so I then bought a 32P(my only brand new prop I every purchased and its more like a 28P...I have to send it back). Obviously the original compressor was on its way out and I really don't know where it makes the most HP or how much it makes now. I got a short video on YouTube (below)....its got CMI TubeTops with 4.5" dry pipes so its pretty loud in the narrow river-LOL
