Prop Work
 
I did some engine work last month and got a few more Hp out of the 502's. My 26P Bravo I's put the engines up against the rev limiters so I purchased new 28P. Talked with Julie at Throttle-Up about doing the lab work on these, as they did on the 26P. The 28"s are on their way and I should have them back in two weeks. It is such a pleasure doing business with professionals. I can only say great things about Julie and Matt. They do what they say they will do, when they say they will do it.

Thanks,
Dail

With the 26P and before the engine work I could get 75 MPH (GPS) @ 5050 RPM's. After the work we got 75 MPH, hit the revlimiter, the DDT said 80% throttle. With a friends labbed 28's I was getting 77MPH @ 4800 RPM's. I tried my new stock 28's (out of the box) and got 75 MPH @ 4400 RPM's. These are all four (4) blade Bravo I's. The midrange numbers are what made me excited---about an eight (8) MPH jump (from my 26P) between 2500 and 4000 RPM's. The numbers don't exactly work to me but Julie said she will get me to 4800 RPM's and perhaps a little more without doing to much damage to the midrange performance.

Give Julie a call and I feel sure that she can help you find the sweet spot.
