Looks great!

Cut the water back some more and fatten the needle and it will run as fast or faster and not take plugs.

10-4 on that Terry

We our in the horsepower months here in Evansville IN.

Testing is a step at a time.

Learning what can be accomplished in the good air.

Many variables to work on and learn from.

Learning how to tune a glow engine in this atmosphere is a challenge, but thats what its all about when we compete.
 
Did you cut the bait box off the back?
This boat is the G2 model with a couple of modifications by me. The tub is shorter on G2.

The later version (GT) has a longer foot print to improve performance in heat racing water.

My Bad

In an early post I identified the boat as a JAE 21GT

It is a JAE 21G2
No biggie. Regardless you're doing it right and Its looking good
 
Tom,

You keep gaining on it. Not much more and you will be ready

to go. The 17/45s will throw 7% more water though. Maybe

You need a little more RPM? Nice lap times. I thought 10%

more was going to drop the RPM a little more. The engine

is running Very Well with that pipe. I have another idea to try?

I calculated 34,146 rpm with 21% slippage rate good for 82 mph.

Thanks For Sharing,

give me a call
 
Tom, In my opinion You are doing this in the way a that it should be done. every one on here including me should take the time and effort to do this. I don't think alot of them here know what is involved, pass after pass keeping notes and doing the math. I am sure with all this effort you have a personal goal. Keep it up this is great reading and great videos.

Oh ya also when your done I will give $19.99 U.S cash for your notes....lol
 
Mike,

Not sure about 90 mph yet, but the next step is almost done.

Tom does a great job getting ready for each step up the Ladder.

Nice Job Tom,

That checks out as early in the vid I noted peak rpm.

If 15% slip 86.8 mph / total pitch 3.42" / average Doppler

before and after camera mic 34,358 rpm. Many passes

all in the 33.6k + range.
 
Boaters,

Here are the numbers on the most recent video.

Leading Edge Pitch is 3.21"

Engine RPM 34,146

Speed Measured By Radar 82 MPH

Propeller Slip 21%

Thanks For Reading,
