look kinda poopy, and craigslist is sketchy about buying stuff and having them send it. Ive done it on numerous occasions. but beware..

LMAO yea I'm no where near jersey but wow that was a quick find.

Actually those numbers are only slightly exagurated, but the gains are impressive.

Removing the clutch fan gains you about 15hp.
Both fans running full tilt 100% consume ~20amps.
10amp load on alternator = 1 hp stolen from engine.

So lets do some math.
+15hp - mech fan removal
-2hp - alt load from efans
=13hp gain. :)

I was good with 13 more horses for less than $100...

Hum... site said 28 amps but I'd like to understand the formula you used to get 10 ampload on the alt? I'm guessing it's taken from the battery due to the fact the alt's actually give them more amps durring charging then the batt needs or the systems actually consume? Or am I fogetting a fundamental. It has been over 10 years since I worked arround it. :shocked: Not going to debate your post because I figured 12hp originally but did'nt sound right but I also figured those motors would draw more then 20 or 28 combined and figured about 35 to 40. You can see how long it's been since I had to play with no factory fans lol.

yea I would but I am in the middle of uncluster f'n what my engine builder did to my Camaro right now so the funds are not going to be there for that for another couple of weeks. I never thought you would find one that damn quick. I figured you may find one in a few weeks to months down the road lol thank you though. Maybe I can talk the Accountant wife to release some extra funds but I doubt lol. I'll check out allofcraigslist.com for more stuff then lol.

Sure, no worries. I ask lots of questions here too.

The Alt only provides as many amps as the total electric load of the truck, up to it's limit (mine is OEM 105amps). So what the Alt produces floats to match the load of the truck(headlights, efans, radio, etc.) upto it's limit. The battery only acts as a storage tank. If for whatever reason the trucks load is higher than what the ALt can provide, then the truck draws from the batt as well to top off the load. This usually happens at night at idle in winter when the headlights, defroster, efans and the heater blower are all on at full blast. The batt when depleted a bit will also draw amps from the Alt until it is charged up again, then it will stop drawing amps from the alt, and life goes on. Which is exactly the reason that the big 3 upgrade is so worthy of doing. It helps to allow a higher # of amps to travel around without causing the dreaded voltage drop on a high amp load....



A few years back when I was playing with HHO, I found a rule of thumb that was for every 10amp load on the ALT, it consumed one horse from the engine. A quick google search shows even lower numbers, but I don't trust them.
Source1:
If using a gasoline engine instead of a diesel, with a slightly lower 2 to 2.5:1 drive ratio, figure on a requirement of about 1 hp per 15 amps of output power

Source2:
About 1hp for every 12 amps.




I was using my dual 16"'s as the example for max amp load not the flex-a-lites. Mine only consume 20amps or 2HP.




As an aside, that's why I was excited to see retorq's e-water pump, because if you can replace mechanical action with electrical action, you gain HP! well...within reason.

unknown at this time.
Perma-Cool is apparently no more as of late last year. The website was suspended but lately a partial Home page has been visible.
Wait there is more....... Apparently they just moved and the sh*t hit the fan. The sales manager Pual told me they had issues with the moved and that a competitor was spreading rumors of their demise so it is difficult getting summit or jegs to take there products again. A new online catalog should be up within two weeks. You can find them at the new info.

What are yall using for wiring? On the newer stuff you can wire it into the stock ECU and have it control it. I like that because it is almost fail proof. If fans from an 05 Tahoe will work, fans from a 93-02 Camaro and Trans Am will work. I ran them on the 1500 HD I had and they worked great. Also can you make an electric water pump and if so which is best to get? thanks
