How much power are those amps?

Planning on running two md-3d and one md-43. Atleast two batteries. Would a 260A alt run all that?

[240 amp Iraggi Alternator Bench Test (258a @ 15.0v!!)]

Here is a 240 amp Ford alternator we built and shipped today for a customer.

Hopefully the music starts working soon. LOL

[240a Iraggi Alternator 1996-2005 Eclipse. (256 amps at 16.2 volts!!!)]

Approximately 1500 to 2000.

Dom

you don't know what the actual engine rpm would be?

[380 Amp Iraggi Alternator Bench Test. (396a @ 15.5 volts)]

Here is a 380 amp 2001 tahoe alt.

The belt slipped at around 51 seconds... I just left it on peak hold and ramped the load up again. Belt started to slip a little right at the end.

Dom

[240a Iraggi Alternator 1996-2005 Eclipse. (256 amps at 16.2 volts!!!)]

6K @ the alt.

at what rpm was that 256 at?

[240a Iraggi Alternator 1996-2005 Eclipse. (256 amps at 16.2 volts!!!)]

U get any info on the panda yet?

[300 amp Iraggi Alternator Bench test. 323a @14.4v]

What does "This. " mean?

Dom

This.

[300 amp Iraggi Alternator Bench test. 323a @14.4v]

The regulator is preset to 15.0 volts.

I wish I could have saw what your wrote the first time.

Why would it make a difference what the voltage was before loaded? Just curious.

Dom

Just out of curiosity, why was the voltage at 15.0 volts before the load was placed on the alternator? Does the setpoint if the regulator you use start off that high?

[300 amp Iraggi Alternator Bench test. 323a @14.4v]

I use an 800 amp variable carbon pile load. You pretty much just turn the knob to the current you want to pull from the alt. I will vid the load next time around.

Dom

what is actually loading the alts down? is it a big resistor bank/ heater thing like a battery tester? or is it something else?

[300 amp Iraggi Alternator Bench test. 323a @14.4v]

Hard to mount duals on the tester.

Dom

dom can you test a dual set up to see what its output is. hint hint nudge nudge lol.

[300 amp Iraggi Alternator Bench test. 323a @14.4v]

Anywhere from 125 to 225. Depends on the car. Crank pulley diameter and idle rpm makes a big difference.

Dom

What are these 300amp+ alts doing at idle?

[300 amp Iraggi Alternator Bench test. 323a @14.4v]

Depends on the regulator. Some regulators will hold voltage until the alt maxes out. Some just gradually fall off with more load. Depends on the car sometimes.

Did you notice that from the vid?

Dom

so once you reach the max amperage of the alt if you add more load the volts start dropping?

[300 amp Iraggi Alternator Bench test. 323a @14.4v]

Here is a 300 amp alt going out today to a customer. 2004 Tahoe single alt. Nothing out of the ordinary. No external regulator. All internal.

Dom

[240a Iraggi Alternator 1996-2005 Eclipse. (256 amps at 16.2 volts!!!)]

If you can get a pic or numbers off the factory alt Ill see.

Dom

that sh!t is sicc...what do you have for a panda??

[240a Iraggi Alternator 1996-2005 Eclipse. (256 amps at 16.2 volts!!!)]

If a belt slips its either too loose or belt is old and no good.

If you notice we use a V-Belt on your tester and it never slips. We keep the belt in good shape.

Dom

since we are on the subject on eclipses'

how well do the 240s act on sohc 3000gts?

I have been told that 250 amp alts have slipping problems...but i would love to run them if they work...

[240a Iraggi Alternator 1996-2005 Eclipse. (256 amps at 16.2 volts!!!)]

Here is another one for a customer with a 2004 Mitsubishi Eclipse. A little external regulation action goin' on.

He got the 240 amp model. Direct bolt on. NO brackets, extra hardware, etc. Same case style as factory. Take the old one off, put the new one, upgrade wires.. your done. No wondering if it will fit or not. ;)

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

In the EXACT 3G factory housing 260 amps.

The 350 amp alt in your sig will not be a 3G alt like your factory.

Dom

Whats the largest alt you have for the stock location on a 2002 Ford Ranger 3.0?

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

Hey Nathan..

You send your alt in? Not sure what you meant.

Dom

im with you preston. Cant wait til mine come back giggity giggity.

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

Nah.. LOL. It does take 2 of em' tho. One motor will do around 240-250 amps at max rpm. So 2 handles it no problem.

Dom

Man im stoked, my 10,000 watt virginity will be broken soon

so does the 4x 5hp's drop rpm when the alt kicks on?

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

Should be here Tuesday.

nice one dom! any updates on the pulley?

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

That would be a custom build.

Ill need to take a look at your stock alt and see.

Dom

how much 4 that alt on a 00 zx3 ?

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

I think the other two did 315. Ill test again.. I dont remember and didnt get vid.

The one I just tested was your stock location alt.

i know dom i was just messin

960 amps here i come

edit: 960+ amps here i come

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

It looks like what is behind my desk.

Your not gonna see that one for awhile. Your not ready.

what does a single 1500amp alt look like?

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

I hand built our alt test station with a lot of balls and few frills.

It has 4-5hp motors for a total of 20hp. There are 5 different size pullies so you get 10 different rpm ranges with 2 different alt pullies.

I wish it was infinitely adjustable but its a monster when it comes to raw power!!!! Ill take that over rpm tweaking. There are plenty of rpm options. I can always use different size alt pullies to come up with any rpm needed.

I have built single alts up to 1500 amps and needed some serious tester capability as far as horsepower. That is why its like that.

Dom

oh so you dont have a speed control? the motor is just one speed?

you always point out that the alt speed is different in every car so im just trying to learn

[Iraggi Alternator 320 amp bench test. 338 amps at 15.4 volts. No drop. :)]

Yes, hwy speeds.

Idle output on the car is so relative. Crank pulley diameter, alt pulley diameter, actual engine idle rpm, engine bog when alt is loaded, etc.

But to answer your question... between 125 and 210. Most cars will be around 140-160 amps at idle.

Dom

what will that Alt put out at idle?

1700-2000 Engine RPM would be highway speed right?
