Anyone running a Whirlwind SW prop

[SWAMPHUNTER45]

Looking for someone running a Whirlwind SW prop to discuss performance observations.

Specifically the Whirlwind Whisper Tip Super Wide in a multi blade configuration.

Specifically the Whirlwind Whisper Tip Super Wide in a multi blade configuration.

Rats...I only have a one blade SW.

I like my 2 blade 80" Whirlwind superwide.

I'm working out the bugs in my LS style engine and plan on turning it 5100 with my 2.37 box.

There is a thread on here somewhere where I believe someone said it wasn't good for anything but racing but from what I noticed it did seem to fall off after a certain RPM when I was running a SBC & 2.68 a little over the #2 if I remember correctly. They rob HP and do not like too much pitch, supposedly. Low end is stout and should cruise great right around 2500 rpm on my light boat.

EDIT: plenty of variables to consider

[SWAMPHUNTER45]

Scotty I would like to find someone on here who has run a 3 or 4 blade Whirlwind Super Wide combo on a heavy rig and pitched it for lower RPM.

The single SW blade configuration is called the "Hatchet Hub" fyi

[scottyroll]

Yeah I figured you meant 3 blades or more but wanted to clown on ya a bit as well as share my experience with the mighty S blade prop

I think Skip Olson up in Alaska runs a 4 blade Whispertip Superwide.

Thanks FISH, I found an email address for Skip and sent him a message to check and see if he is running the Whirlwind Super Wides.

If anyone has any experience with them or knows someone running SW blades please pass the info so I can reach out to them.

boat we run one on isnt really what id call heavy (3 blade 80) but i gotta say its a beast and really quiet seemed to perform best in my opinion at 5400 with a 2.68 got it choked down to 5200 now and it runs good just was better at 5400

[SWAMPHUNTER45]

Thanks Bruce that's what I am trying to find out.

I've run the 80" SW in a 3-blade configuration with a 2.68 gearbox governed to 5500rpm and it's a stout piece.

Thanks Shane

4 Whirlwind SW but in the older style without the swept tip on a heavy boat thru a Stinger 2.55 gear box.
What sort of questions do you have?
Also sent Skip a link to this thread.

Rpms run 3600 cruising to cabin with 3-4 people and a few hundred pounds of stuff on on boat.
Max rpm set at 4800. Combo of deep and skinny water to get there.

Have stuffed over 2000lbs of hunting camp, fuel, etc... into boat and she gets on step, still runs ground and climbs beaver dams. Return with moose or caribou and gear less gas burned and she still steps the weight. No complaints.

Thanks for your data. I talked with Skip last night.

Given your newer gearing and that such a prop will perform at those prop rpms, it sounds like you
may have well hit the jackpot. There's few things better than having a quiet bulldozer.

No highjack. But with all the upgrades and improvements with these props just wondering if anybody has a set of 68" wisper tips they no longer need and are willing to sell. Mine choked to death on a backpack.

[SWAMPHUNTER45]

It appears that we are on the right path Deano.

Speaking with Skip Olsen in Alaska provided a lot of insight. Not hearing anything bad so far, just hard to leave Sensenich with them in my back yard. Hearing several "S" blade users complain about vibration and that they are "power sponges" when pitched has me looking at other options. Little more time before I have to order but trying to make an educated and informed purchase.
