The Forgotten On

That's if they could get inside.

Funny, it is the exact same size as one of my 100 count Super Cedar boxes so I thought what fool returned these. Later I noticed it was from Precision 8:30 pm. If you want it come and get it. I owe you.

Not to worry, your alternator is safe! I think Greg has me covered
Merry Christmas

Six more ready to go, today.

Mary will get some of them out today....she is waiting on a couple of people to send Emails back.



Thanks to all that ordered this high output alternator! I never dreamed the desire for this high quality, high output alternator would be so great. I'm already past the break even point for the machining of the aluminum covers!

There's still time to get the introductory special price. We will be in the shop through Wednesday, next week. If you miss us, you can send me an Email or a PM before the 1st and the introductory price will still apply.

Thanks again, for all your support!

Got to thank Greg for doing this for two reason, great product and I've sold a few harnesses due to it.

GregBBRD

Thanks. To get your approval means a lot! Hopefully Roger will stocK them and you can install one (or many). The function and fit lives up to the pictures!

And I'm glad you are selling looms....seems like every car needs one, unless they have less than just a few miles.

I've been disecting all the ones I change in my own shop....the condition inside the covered section (by the airpump) is appalling!

the tracker says the little brown truck is on its way.

after the triple taped package is open I'll post pics of the new 'power' unit

The Browns (Greg, Mary and the truck) outdid themselves! The UPS tracker said next Tuesday but it got here today. Whee! But I don't know where you guys get "20 minutes", I spent that getting the box open and admiring it!

Here it is, about to get hooked up and lifted into position. Everything fit perfectly. (That's a GB harness, fit last year when the engine was redone).



Gotta love Bosch. The spec is 80A at idle, 150 max. I warmed up the engine, alternator was putting out 14.3 volts at around 30 amps. For a load test I set the idle to 675 rpm, lights on, blower on high, and the alternator put out 86 amps at 12.97 volts-- no drain from the battery. That's at a stock 675 rpm idle. The comparable number for the stock alternator was 55 amps-- enough to run the car and either the heater blower or lights: Choose one.

The scale on the current meter (big display) is 1mV per amp, so 86.1 amps from the alternator. A separate current meter on the battery was showing a small charge (1-2 amps).



After running at idle another 30 min or so it was doing 80.1 amps at 12.88. If I dropped some load then the voltage bounced up to 13.5 or so, and adding more load the current stayed at 80 amps but the voltage dropped-- and the battery stepped in to help. That is all as expected. It's not mid-summer in Phoenix but things were pretty toasty-- car was indoors in our heated shop (exhaust vented outside). No airflow, and rad fans were cycling.



Then I set the idle back up to 800 (the usual idle for our GT, and also what most alternators are spec'ed at for idle ratings). A load of 104 amps was the best I could come up with quickly, the alternator just laughed and put out 13.54 volts-- i.e. enough left to add charge the battery, if it needed any (it didn't).



I'll get some miles on this (and let the brushes get properly seated), re-tension the belt and then do some full-load testing, I've got a load box that can add another 50 amps.

But first impressions are that the Bosch alternator behaved exactly as expected, and is a big step up from stock-- especially for the later cars with bigger loads, electric rad fans, etc. And Greg hit it out of the park with the billet housing and adapting it for the 928.
And Mary, what can I say? Well done !!

Thank you Jim for the very detailed writeup on the working of this alternator. Not that anyone was doubting GB's work, but we appreciate it nonetheless.

Arnoud

Thank for having developed this for the 928 community, Greg!

PM sent to you for ordering of 1 mat one (just before the New Year starts here in Finland, only minutes away now).

dr bob

Jim -- Excellent results and excellent (as always...) verification.

Greg -- win-win for all.


Thanks to both for making a great package!

GregBBRD

I don't get PMs on my phone, so I won't see this or any other order by PM until Tuesday, bit rest assurred I'll take care of all.

Thanks for your order!

Hilton

Just caught up with this thread after getting home from vacation.. email incoming, I need to order some other bits too, will ask in the email about them.

mdkelly1

Couldn't resist putting an order in for this yesterday. Greg has done all of us a great service by making new/better technology available for 928's. This will be especially helpful here during the summer months.

GregBBRD

No worries.

I only get very intermittent Emails where I'm currently at, so I can not respond. (Also not getting PM's.)

I'll be back in the office on Tuesday....and then I need to go through all my communications, plus get the shop back moving, after this break.

Because of this, I will happily continue the sale price a few days.
