I'm sure you don't use the stock belt. You may have to use the belt made for engines without AC. or just do the math and buy a belt that is shorter.

yeah, i guess that would always work.. maybe ill add one of those things along with the electric rad fan. should free up some horses right? im not expecting no 15HP increase, but anythings acceptable

The electric water pump still has to move at least as much water as the stock pump, which requires the same amount of power because it has to do just as much work. I still fail to see how an electric water pump will gain you any HP.
it is an electric motor! thats how. the engine is turning the factory water pump by mechanical power. i guess next you will say you fail to see how a supercharger makes less horsepower than a turbo, same concept.

And the alternator is turned by?..... That's right, mechanical power!

which is making electrical power!!!! like 95_318slt said. a 20 amp draw it is .38 HP. much less than 15hp

You made our point. You ran out of arguments with ^ statement. The electric fans, pumps, etc, have less mass because the designers don't have to worry about building them to withstand a 300 ft*lb of torque motor without being blown apart. They have lighter weight parts and are therefore more efficient. Like I said before, they wouldn't be made if they weren't more efficient because who would want to wire them up for no reason?

Ok, you must not have read what I wrote. When a 20 amp electric fan is on (typical draw of a 16" fan), it is using 0.38 hp. When a mechanical fan is "on" (clutch engaged) it is using up to 15 hp. When an electric fan is off (cause they don't run all the time either), it is using 0 power. When a mechanical fan is off (clutch disengaged) it is still spinning from the friction in the fluid clutch, so it is still drawing some power from the engine. I don't know how else to explain this.

Look up conservation of energy and get back to me.

There is not a 15HP difference between the rotating mass of an electric water pump and mechanical pump. The pump is still moving at least the same amount of water, doing work uses energy, it's still the same amount of energy no matter which way you slice it..
People are largely stupid, case in point, throttle body spacers, tornadoes, 45 electrode spark plugs, fram filters, ect,.

I never disputed this, you must not have read what I wrote.

I'd still like to see independent dynos, until then I'll stick with real power mods.

Don't start with me dude... I'm a mechanical engineering student... I understand this stuff. I'm spending a lot of money to go to school and learn it. Theres this little thing you're leaving out called EFFICIENCY. Yes, it takes the same amount of energy to move an given amount of water, but it takes more energy to move the heavier parts of a mechanical pump. You can't just take external work into play, you need to consider internal energy and effieciency.

And I never said an electric water pump would free up 15 hp, but it should free up some. I was just giving an example I had the facts on.

And do a forum search, nobody here has ever said a throttle body spacer works on our engine... everybody has said they suck. And nobody has said multiple electrode plugs help our engines... everybody has said stay away from them.

Please research the facts before posting comments like that that makes yourself look stupid!

pretty sure this should have been mentioned a few posts back

Did I touch a nerve because I haven't backed off?
Most people know those products are **** but they still make them because people still buy them. The argument of "why do they make them if they don't work" is ****.

Show me independent dyno results, until then **** off.
