Interesting !

Does the fan pull or push air ? As the fan is push air into the bilge it may be competing with Bournellis Principle. Meaning, laminar flow from the deck. Or, airflow from on top of the deck that may produce a low pressure area at the grill.

As the fan is to pull air, is it possible it will create restriction ? Perhaps, ILO or in addition to the grill a reverse blower scoop would scavenge/draw airflow from the bilge.

Good question. I was very concerned with the amount of force
that the entire assembly would see. Considering they are directly
above the Turbine exhaust.
The mounts are rated for 150lbs each The picture is diseaving
they are about the size of one of those chocolate donuts you
get at the super mart.
I think you mean a shear load when you state "Downward load"

They are threw fastened with 3/8x 16 Stainless bolts.
I am more concerned with the plastic fan breaking off.

I got them at Mcmaster-carr.

Excellent suggestion and quite frankly is exactly what Gary at Fliudyne suggested when given the photo of this.

Some other variables to consider how much air is the main turbine fresh airscoops pulling in? Would the air stall before them. I have 6- 4 inch transom vents. is the engine bay under negative or positive pressure?

I have since made cardboard templates that I am giving to my sheet metal guy to create a small scoop. I cannot go to high with
this fearing it will constrict the main turbine fresh air scoops/inlets
that the grates are directly inline with.

Yes fan does pull. In a static test for 20 minutes measuring the
in and the out of the cooler with a infer red gun. in was 201F
out was 181F. T-stats were overridden and boat was on trailer.
I could not push the airflow from the fan where it is mounted
because it would draw the heat from exhaust at idle and no wakes.
Going to run some in water tests this week.

Interesting ! A wind tunnel would be nice....The static trailer test may not consider the high pressure/low pressure areas created by deck and tunnel, at different speeds....Therefore, scavenging value is not known. Or, opportunity for decreasing/managing deck burble/lift. One test example (though crude), attach streamers to various points on the deck and hatches and go for a run....That may help with scoop design and location....Also, as a proponent of venturis, there may be opportunity for more of your creative thinking...Good Luck !

HEY, I heard it's your B=day. Miss ya , your pal, JJ=b=good. Sunday is do DAY !!!!!!!!!!!!!!!!!!

Happy B-day G hope block was a blast.
-Mike

You might give some thought to what THEJOKER said about the sharp edge of your windscreen. There must be something that can be put all the way around to soften that edge...

I really like the paint, the colors and the design. Beautiful boat! :thumbsup:

C,mon Keith Lets have Peter build us a new Carbon/ Kevlar
46 have Jim build some 703,s run some BPM,s Zeigart
shafts throw on some 5 axis props and go racing. KNOT-RIGHT


Sounds like a plan! :cheer:

And why would you not want to put Arnesons on it?

There is a 45 degree chamfer milled across the entire perimeter
in the earlier photos it is not visible.

These photos shows it a little better.
not bad advice on capping it with maybe a wide round molding.

Would you and Howard consider a part sponsorship:eek:
Im Still workin that deal on the 8,s in florida.


Here is the custom powersteering / oil cooler fresh
from Gary at fluidyne.

Gerry, that unit looks kick assss ! Guys the wind screen's exposed edge is rounded in shape a complete 180 degrees there are absolutely no sharp or right angle cuts around its total length port to starboard. :party-smiley-004: G.A. Weston has his eyes on you !

Arnesons are good. :) I was just quoting someone...

Who?

Oops I just noticed I didn't put his name there. It was knot-right p.59 post 588.

use air not H2O
 

Come on guys this conversation, currently is all about lightning the boat, reducing weight and keeping water cooling out of the picture. Please catch on to the direction of where G. is going. By eliminating water as a coolant in any way shape or form he could ultimately reduce the boats displacement by nearly 500 lbs. and by doing so potentially increase its top end. The new coolant system will eliminate the external plumbing requirement that a BB blown engine requires for cooling, which is currently already installed in the boat. PS: with the new system the boat has been tested conservatively this past Thursday at just over 102 MPH with good engine oil temperature readings. YA WHO :eek: - :D

By the way Cat who is this Rik guy anyway ?

Jay Jay its the guy who does the Arnosons
-Mike

Thursday????? where the F was I? I had a 12 pack of corona for that day if Id known.
-Mike

It was in St Pete Worlds 1999 or 2000.....36 Eliminator " Roll Off" F3 Boat.....hook and spin........very violent. My background in racing and mfg taught me in a worst case scenario you want a clean dash , etc during a violent ejection. Just trying to help and this thread is a great one!

Danny Hankey. I was on the balcony at the Vinoy and watched it happen. Scary for oh so many reasons.

:kiss:Do ya think ? You are 100% correct my fine lad. How R/U ? and see you at Borden Light. Be sure you have a rig to show me.

We need KERO !

Thank you for the info and sincere concerns.

Jay i will have something. Also i hooked Gerry up with a sweet tank to save on Karo and get some serious gallons.
-Mike

Good Boy That u r :drink: Now lets get back to the thermal properties required to cool the turbines oil system, ol'lad ! PS what ya gut on the h2O ? tis it a secret ? OR IS IT A CORK :party-smiley-004: remember me and KIR are watching U and so is WESTON WARREN M. WHITTIER WELDON & MMM - :eek:

Its Sutphen called Ice Scream. Heard of it? Ill see if i can get a pic of it or if you hae one laying around post it:evilb:. Well every day things change in about a month ive had 3 differant boats so we will see. As of now its a 272 LS sbc's alphas.
-Mike

knot-rite,

where do you run this beast? looks like your in RI...

I met Danny at the 2001 Ft. Myers race I think it was, or maybe the Corpus race, my memory escapes me. :bong: He had a huge round cage on his right leg I believe it was. He couldn't get around very well at all but he was there...

Danny I hope you're healed now. :)

yes Narragansett bay


the air to liquid exchanger combined with a liquid to liquid cooler
replaced all of this.

http://inlinethumb35.webshots.com/18...600x600Q85.jpg

No more water!

The liquid to liquid cooler is doing two things cooling the oil
and heating the fuel. This is a plate style exchanger with working pressures of 350psi.

This is installed inline right after the fuel control before the fuel divider.http://inlinethumb06.webshots.com/44...600x600Q85.jpg

Hey G now arti has his sea strainers........
-Mike

No Mikey Artie has unlimited funds and needs something bigger
and new.:drink:

Here is another upgrade.

The former caliper activation system was operated via air.
This worked fairly well however it is complex and heavy.

Brakerite offers a electric over hydraulic system that was originally designed to be used for your disk brakes on your trailer.

This works well as a replacement for the original air system i used.

http://inlinethumb26.webshots.com/16...600x600Q85.jpg

all this replaced by this unit.

http://inlinethumb47.webshots.com/44...600x600Q85.jpg

Cool G I need to swing by and see the upgrades. As always a case of corona just let me know Corona or Lite also 12 or 6'er
-Mike

12 works fine better to much then to little.


Next upgrade will be downsizing the amount of batteries.

Currently running six Blue top optimas.

Thinking on three of these bad boys

Gerry,
Tried to PM you, but your box is apparently full. Just wondering how the boat's doing and if you got your drive put back together?
-Tom

Yes Tom Humpty Dumpty is back together.

Haha nice, is that the new name going on the back of the boat..? :D
Is the boating season pretty much done for you or you gonna head out a few more times?

Not yet bro!
