vv,
Let me know what props you wind up with. I just got mine going .I want to get the bugs ironed out and get the boat dialed in for speed.I ran the boat last year in a run with velocity. Steve said the boat could run over 100. I think if i work with my tow a little maybe flip my props around it might get there .At 92 i had more stick but she was squirrly and ididn,t want to damage the boat |

104 will be realistic,I am turning worked 32 four blades and it runs out of bottom before it will run out on the big end,it can and will be like driving a 22 on steroids.:drink:

No such thing as running out of bottom. Running out of balls might be a possibility :eek:.
If VV can turn some 32's to 6000 @ 10% slip he should be at 109-110 mph. 32s at 6200,how fast is that with minimal slip.:rolleyes: |
Make sure that when you test , you trim up enough to get all the rpm's out of those props . Trim settings on Velocity's are everything when it comes to squeezing out speed and rpm . :cool-smiley-011:

Hi Hyper, I wanted to do some testing today with 32's but it's raining here like "a cow pissing on a flat rock" I'm telling you "Big drops close together".:eek: Have you been out yet this season?

32s at 6200,how fast is that with minimal slip.:rolleyes: RPM divided by Gear Ratio, Times prop pitch, divided by 1056, equals theoretical speed. Then apply slip factor. Here's the math Bill, at the 6000 rpm. 6000 div by 1.50 = 4000, X 32 = 128,000, div by 1056 = 121.21 mph as theoretical top speed, then multiply by .90 = 109.09 mph at 10% slip. @ your 6200 it is 112.727 mph. That's how it works! Basic math. Course if you're mathameticaly challenged you can run it thru the Bam Speed Calculator ......... and get the same answer. :rolleyes: |
I have learned instead of changing props just buy the biggest size then add Horse Power to get the speed you are looking for.
