I do believe I answered you about 40 post up....somewhere around 8am this morngin that was answered....here let me quote it again for the people who CAN'T read...
It really takes posting something 3 times for you to read it

 

Well if the alternator isn't putting out it's "capacity", then the battery is supply the voltage right????

Why did you evade the question.....because you knew you were WRONG?

The correct answer is BATTERY!

 

Bob is trying to take me to task. But yet completely ignores questions put to him. Come on Bob.

My e-fans both have a much tighter shround around thier OD. This greatly improves the delta P vs the stock ford design. When you have an axial flow pump (no matter what the media) the blades almost never overlap. This is why axial flow types are kept in realms where high rates of flow but not much pressure is called for. The only way to build pressure is to add stages like in a jet engine, or to overlap the blades. (some turbo jets do this)

Besides Bob. If you don't understand what blade over lap is or does.. what would showing you calcs do? What would you want to see? Blade surface area? That's no biggie. Number of blades? No biggie. The bleed on the I.D. and O.D. on the blades? No biggie. You ask for math to what end?

Yes I do get the CFM "claim" from flex-a-lite. So what?

At the end of the day Bob. My truck stays cool, I've freed up TQ, and get better MPG mileage. At some point in time my investment of money will pay for itself in MPG gained. Besides.. this stuff is just fun to me. And.. it lowers my ETs.

Alright, let me say this one last time since you are too freakin stupid to understand it...

IF YOUR VOLTAGE READING WITH THE TRUCK RUNNING IS 12.3v, THEN YOU HAVE PROBLEMS WITH YOUR ALTERNATOR. A WAY TO FIX THAT WITH THE UDP's IS TO INSTALL A SMALLER PULLEY ON THE ALTERNATOR. THAT WILL SPIN THE ALTERNATOR BACK UP TO NORMAL SPEED AND YOU WILL GET THE VOLTAGE BACK UP TO AROUND 14.5v WITH THE TRUCK RUNNING.

Do you understand now

 

Bob doesn't understand that. He comes to a site where people MODIFY their truck and bashes EVERY modification. I have even seen him bash a modification to a Ranger where the parts were stock on another Ford (that would be the Taurus efan mod by the way).

He wants to bash efans, yet manufactures put them on NEW vehicles every day; even Chevy is putting efans on their 1500 Silverado's with a towing package.

 

My understanding is very basic in that subject. My understanding is the battery is the "thing" that stores energy. The vehicle uses this power. The power is regenerated because of the alt. Seems to me that if your sitting at idle and using more power than is being supplied to the battery. Your running a deficit.

Here is the thing though. Who in thier right mind would argue that it's a problem with the typical ranger running a UDP? As soon as the rpms go over 900-ish the battery is now being charged. Don't know about you guys.. but I drive everywhere I go at more than 700-850 rpms.

Rich

 

I'm not impressed with your BS. That "shroud" you are talking about on your e-fan is used to keep the plastic blades from flapping around, it serves no useful purpose as a shroud for pulling air through the radiator like the mechanical fan has!!!

I'm not surprised you would believe the CFM claim from a efan MFG!!!

 

Have you seen the shroud on his fan?

On my Ranger with the UDP, I had to be up around 2,000 rpm's for the voltage & amp to be at normal output from the alternator. When I put the underdrive alternator pulley on, it brought the rpm back down to around 1,000 rpm's to produce the normal voltage/amps.

 

Ah don't bash hmi too much. He's just an old guy getting kicks from people who are young and impatient. Too bad he doesn't use more science.

Rich

 

The fan blade is a single molded piece that has a "shroud" on it. The fan assembly also has a shroud. Both act as bleed limiters. Bob, I'm tellin ya just like I told you before. I learned from the best. Dr Korst at UI. He opened my eyes an awfull lot about pump design.

As far as the claims of flex-a-lite. I've not tested them. Neither have you. So who's got proof it's accurate or not? Neither one of us.

Rich

 

Well, Chevy uses the efan on their BASE Silverado 1500, no towing package!

Even Chevy uses a mechanical fan/clutch on the HD trucks!!

 

Rich, let me tell you this plain and simple! If you hadn't screwed your truck up with UDPs, and the e-fan, you wouldn't have to screw with an additional e-fan on the aux. tranny cooler, and be worried about the tranny temp!!

The OEM mechanical fan/clutch, and pulley design are plenty robust to handle extreme conditions, which you have limited by the UDPs, and e-fan!

 

Your point has some merrit Bob. But I did'nt do this because I'm "worried" about the tranny temps. I did it because I'm a gear head and like to modify cars. This is just "fun" to me. I find it "fun" to modify cars and then post about it on car forums. In a way.. kinda like you think it's "fun" to not modify cars and then post on car forums putting down the idea of doing such.

So... we are no different than two dogs barking at each other. Except.. I'm barking with science on my side. And you.. your barking with gut instinct on yours.

LOL..

Later,
Rich

 

Rich, we can agree to disagree! No, I'm not using gut instinct, I'm using basic engineering principles, and many years of experience!

I remember a post or PM from you sometime ago, when their was a debate about K&N air filters, or intakes, you admitted that the gains simply weren't there.


I hate to see these youngsters with no technical savy at all be sucked into believing the aftermarket product marketing BS, and wasting what little money they have on
their useles products!

I also appreciate quality machinery, and hate to see it botched up!

 

some of the dohc 2.3L rangers come stock with an e-fan.

 

Actually Bob, If my memory serves me right, I do recall someone on TRS telling and SHOWING you pictures of their '06 1500 w/ tow package has an electric fan....You just got owned.

 

Check it back out......I showed a GM parts site, calling out a mechanical fan clutch for his truck!!!

As usual, you are WRONG!!!!

 

As in every "mod" you can do to a modern car. There are trade offs. *if* your looking for high rpm power. The K&N kit definately does deliver. (I measured the before and after power gains)
*if* you think your going to gain MPG. Think again. It doesn't decrease delta P across the throttle body unless the TB is at least 50% open.
*if* you think it filters better. Wrong again. There have been many independant test to prove such.

I think that too often people have a "bandwagon" that they jump on board with. Then they selectively pick out facts that back up thier agenda. Bob I respectfully feel that you fall into that category. I try pretty hard to let the chips fall where they may.. based on measured results.

Bob I'd hate to hear your comments on my 800hp fuel injected, supercharged, and direct port nitrous injected Lightning. I'm afraid that level of modifying a modern ford would send you into convulsions. LOL..

Take care,
Rich

 

Rich, I found your PM you sent me regarding K&N filters and intake kits:

"I'll definately agree that there is not a big gain to be had with these things. Not much of a gain at all really.. unless you spend time at 4000+ rpms you won't even see any. Like I've stated before this stuff is just fun. Especially in a internet enviromnent where *nobody* seems to use factual data."

 

You better dig a little deeper, the parts you called out aren't even in the cooler line circuits!!!!

Call up your tranny kit folks, and they will set you straight!!!!

 

you people have no maturity at all, quite sad really, only rich is handling himself in a mature manner
