Anyone know of a simular product for the 6.6 Duramax like the Cyclone electric fan clutch for Ford 7.3 and V-10s?

Dougrcpa said he was on to something that you describe. Please PM him. I am a little interested also.

Here's a link to the Ford Product that I found. Contacted the company and they said nothing was in the works to fit a Dmax. I think it would be a "cool" addition for the Dmax and would give you 40 more hp when not engaged.

40 HP? I don't think so. That's what my sportscar consumes at 70 mph fighting wind resistance. Our fan consumes 20 HP max, at full tilt. I'm not positive, but don't think ford makes a fan with 2x capacity of a duramax.


Don't you love what some idiots will do to sell something?

Nice artwork. Now let's see, what would be a good reason to chart one fan engaged, with the other disengaged? http://www.dieselplace.com/forum/smileys/smiley5.gifI can't think of one, except: smoke and mirrors!http://www.dieselplace.com/forum/smileys/smiley3.gif


This chart compares a broken, locked, thermo-viscous clutch, with the new electrically activated one, both on a cold truck (seeing as the cyclone never engages).


Love the creative marketing, I think my ex-wife was on this project.

Yes, I understand, I ran across this back when in my "naive" stage of trying to understand our own fan better, when my issue was the noise and power loss.


The cyclone has solved some issues for Ford, and I like it. Wouldn't mind a Dmax version.

Don't you love what some idiots will do to sell something? THE IDIOTS YOU ARE REFERING TO PAY MILLIONS IN SPONCERSHIP TO THE NHRA DRAG RACERS I AM A US GEAR DEALER IVE SEEN THE F350 ON THE DYNO 41 HP GAIN WHEN FAN NOT ENGAGED, US GEAR ALSO OWNS STRANGE ENGENERING, STRANGE AXLES AND RING AND PIONIONS TO CALL THEM IDIOTS IS A LITTLE HARSH CONSIDERING THEY HAVE A 5 MILLION DOLLAR A YEAR BUDGET FOR RESERCH AND DEVELOPMENT. NOT JUMPING YOUR CASE JUST FYI, HAVE A GREAT DAY.

..and that just proves when you have a big wallet, the get the best engineers maney can buy. Slick 50, another great example of slick marketing.


So you believe the F350 fan pulled down 40 HP? Did this vehicle have a CAC (intercooler)?

That's great for a dyno run, what 10 seconds? Then you you have to drive home, back to reality. Our trucks suffer from a thermal instability under severe hi-load conditions, so I am completely on-board with any mod that will give power back without a heat consequence. Unfortunately, this is not one of them. The chart above shows one fan sucking, while the other is not, so it is worthless marketing (a lie) to anyone sharp enough to notice. It doesn't compare anything that is useful in the fight against heat, a scientific aberation.

If you want something that WORKS, you'll have to wait for the vsco-electric technology to be released. The viscous drive does a much better job (than an electric actuated unit) of ensuring that there is a constant flow of air across our coolers.





Now as for the marketing used the way I see it, we need:





OEM vs. Cyclone engaged This will be fairly close with Cyclone likely taking more due to a somewhat more positive engagement.


OEM vs. Cyclone disengaged. Again pretty darn close with the OE taking more. The OE will carry on up to around 1500 rpm (clutch hub) whetre it will "break away and run at approximately the same speed as the breakaway.





The Cyclone last I checked will fully engage at idle. It pretty much has to in order to maintain AC and oil/trans cooler function...





The cyclone CAN be set to cut in much lower temps, but then there's the instantaneous application of HP robbing power again...

I have been reading about the EV's. They (GM) were suppose to already be doing this by now. Apparently it was an embarrassment for Behr, something about almost no modulation. Edited by: masterp2
