Awesome milestone Dan. Really great to see the 101mph.

Interesting on the different prop dynamics.

Since this project is winding down, and speed was found by
removing contents from the cabin, is “remodeling the downstairs”
the next project?

LOL .
Please no more projects !! That cuddy is never going to be light .. ever see how much crap women bring for a weekend? 10 outfits, 30 bikinis, hair dryers, straighteners, shower stuff, hair stuff .. times 2!!
I was actually not going for a speed number this year , I had given up on it just wanted to build a reliable set up with low boost and good safe tune.(or another "garbage motor" as Saris racing who are the best ever at everything ..coined all my builds)
Where ever the speed was I was going to be good with.
Then after break in and tuning I gave it some throttle and thing takes off like a rocket and hits 90mph with very little effort.
Then I got the bug again.

Lightbulb interesting weight.

Iron heads , extension boxes and 5`s .
Weight in 2013





Aluminum heads, extension boxes and 6`s.
I thought for sure the diffence would be more with the 6 drives and transom assemblies.

weight 2023




Kid apache and some others said it would be too heavy with 6`s and the water would be up to my exhaust.. lol Good talk

Go tunnelcram!
Any plans to Dyno?

I researched bsfc numbers when you estimated that. Not a precise estimate but gets you in the ballpark. The E85 mix certainly confuses it a bit too.

Are you just dumping a little E85 in your tank?

Ya, that run was 10 gallons E85, 17 gallons 93 each tank. Flex fuel sensor says that`s 33% alcohol.

That math doesn’t work unless it was extremely low alcohol e85.

unless you meant 10 gal e85 and 34 gal e10 total? I get 27% for that.

10 gallons of e85 (true 85%) and 17 gallons of 93 pump(e10) is e37.
