I'll post what I've seen...

I just installed the smaller 75 amp HOP ultra mini. I run on gas with an electric fuel pump, water pump, fan,and electric shifter. Here is the data from my Racepak before and after:

RPM Before vs. After
1500 - 15.8 vs. 16.2
2200 - 15.6 vs. 16.3
5000 - 15.6 vs. 17.2
6000 - 15.8 vs. 17.4
7000 - 15.8 vs. 17.5

During the run only values....

Minimum - 15.6 vs. 17.2
Maximum - 15.9 vs. 17.6
Average - 15.8 vs. 17.5

It's the standard pulley on the alternator and the drive pulley is 4 inches. Looking to get a 5 inch drive pulley so if anyone has a lead on a CV Products style twin-pin 5 inch pulley I would appreciate it. Hope that helps.....


Great info, that's what I was looking for.

Was the first set of readings with fan, water and fuel pump running?

If so, it looks like what you have will keep the battery up, no matter what you have on. Even at only 1500 RPM you still have over 16V.

HOP is good stuff!


All of the readings are with the fuel pump, water pump, and electric fan running.

I don’t need a data recorder to tell me my battery is charging, that just adds note load to my system. Only running ignition, waterpump, fuel pump and fan on my car. I still shift by hand as it’s not that difficult.

I do have a volt meter in my car and it’s over 18 volts going down the track.

who knew a few posting here are geniuses, reporting astonishing results that defy logic and the manufacturer's application recommendation for using this ultra mini alternator in the application I described, despite the many racers, HS professor and myself amongst them, that found this alternator to be useless clapping

FYI, I have a nice shiny one for sale, let the bidding war begin. Big Grin

Hey 1320,
I'll pay for shipping for a useless alternator since they aren't worth anything. It'll clean a spot on your shelf! Big Grin



Cool

It’s a waste of time and money but yet he wants money for it.
Some people when they can’t make something work the day it’s junk and all wrong, never their fault.

Before this thread, I didn't know that there are still those that believe this alternator actually does something who knew Eek because everyone I know and race with knows it doesn't. Razz

Of course I want $ for it Roll Eyes , I paid $ for it! I'll throw it away before I give it away.

Some people are so dumb, they could have $1000 and lose $500 then find $250 and they would still say the $250 didn’t help.
