Another Okie style video

One hand on the wheel,
One hand holding the camera,
Passenger in the front seat, 210#
Complete with toolbox, cooler, anchor, etc. The usual Lake boat stuff.

Cool! :D

[Her454]

I want my alarm clock to sound like that..................... :)

[BigBlockBaja]

Very Very Cool!!!!

[MudPumper]

Looks like the GPS got up to 102 just before letting out of it. Nice.

[kp216]

Cool video Mark! That thing sounds great. :D
Am I gonna see you at Tablerock again?

That was just a far-out ride. Musta brought tears to your eyes.

I'm guessing by the whistling sound that you are turboed??? Very Cool!!

[Cs19]

That thing runs hard Mark. Very nice.
I cant believe your able to lift that hard, if i lifted that hard in my 19, It would get ugly real quick. Im assuming your not running a whole lot of shoe in there? When I started dropping the shoe the shutdown got worse, but the boat got alot faster.
Anyways cool video, thanks.

[Unchained]

Thanks for the comments,
The engine is turboed, you can see 20# boost on the gauge on the dash.
CS19, since I made that duct that goes over the pump intake last year I've got some real interesting positive characteristics.
It contains the water that would lift the back of the boat on shutdown.
My pump intake pressure that I checked the day of the video was 60# at 95 mph. I've since taken a .060 shim out of the shoe to decrease the intake pressure.
The bottom of the duct is 3/16" thick stainless and is located about 3" below and 7" in front of the biting edge of the shoe. It is sharpened to lead the water up and into the pump. I feel I'm able to use less shoe to get plenty of water into the pump.
The boat shutsdown real smooth and never gets squirrley.
Tracks real straight too. I feel I'm ready for some top speed runs now.
It's interesting that on the video I lifted the throttle at 96 mph and the boat went up to 102. It was still pulling hard when I let off. With no safety gear on I didn't want to push it any more.
KP216 I'll see you at Table Rock Lake next month.

A local outboard drag racer and myself setup a race course on a local river and did some test and tune saturday.
Here's my best 1/8 mile run to date, both hands on the wheel this time.
www.childsdale-ind-prop.com/uncheighthmi.MPG
We had a 125' distance from a rope line to the start line.
I got up to 116 mph which exceeded my expectations for the 1/8 mi. point.
I have some oil pressure problems which I can't quite figure out. With 10 quarts of oil it seems to clear the pan and not drain back fast enough after being at 7000 rpm for 4 or 5 seconds. I may need to go to a dry sump setup.
A spectator got a great video of a run between me and the outboard which I'll put up later.

Woah Momma! That's too cool! Someday......... :idea:

[ShutYaPieHole]

sweet just sweet

[mexrunner]

thats bad ass thanks for postin the videos

[cave]

Unchained thanks for both digi vids! Somehow I got sick this 3 day weekend and these vids make me feel so much better. 116 AWESOME. Love the wind-up sound too. Again thanks for the ride.

Hey Unchained, do you have oil drainback lines installed on your heads?

[Unchained]

Hey Unchained, do you have oil drainback lines installed on your heads?
I don't have any external drainback lines from the heads. It just drains back through the lifter valley. I did install 4 restrictors several years ago at the ends of the cam journals to limit the oil to the lifters.
The aftermarket aluminum oil pan was made by Williams Manufacturing and it has a flat aluminum tray right under the crank which I''m guessing is supposed to control windage. I'm thinking it may want some slots in it to let the oil through.
The way it is all the oil has to hit the tray and then drain off the back edge to get to the sump.
This has been a problem for a while and I've got to get it figured out.

With how good that thing sounds and how fast it runs, it would be a shame to damage the motor due to some oil issues. Hope you get cleared up soon. Thanks for the vids. Good times. :cool:

[cole13]

very cool video's. That sound is awesome.

Your oil pressure issue at wide open throttle is likely due to windage. with 10-quarts of oil in the pan and the boat sitting at a 4 to 5-degree angle (or more)under acceleration, the oil level will be above the windage tray (if your pan has one), allowing the crank to grab it and fling the oil everywhere. Drain 2-quarts of oil out of your pan to keep the level below the tray when the b oat is running and I'll bet that the issue will go away. I've seen as much as a 30-horsepower gain on the dyno by NOT running a 10 or 14 quart oil pan at full capacity. I've tested it several times and its been a repeatable gain on several different motors. My blower motor will fluctuate oil pressure greatly at wide open throttle if there is more than 8 quarts of oil in the pan. I run 7.5 quarts now and have zero issues with pressure. something to think about if you've already exhuasted all other possible solutions.

[Unchained]

Cyclone,
Thanks for the suggestion, I was ready to change oil anyways so I'll try it with 8 quarts.

The video was taken from about 30' past the 1/8 mi. point.

[Kindsvater Flat]

last link doesn't work but beating the whacker kicks ass!! You need to post this in bench racers!!

[bakerjet]

not working for me,bummer. got the first one coooool.
