I'm OK with customers swapping-on a Metco or another aftermarket pulley. THAT SAID - KEEP AND EYE ON THE FITMENT! I have zero experience with how these pulleys engage with the shaft on the Billet units. The shaft is very different from the Ford 6G that metco designed their pulley to fit. Also, the only reason you need the aftermarket pulley is because a Ford 6g has a max rotor rpm around 10k, the Billet Tech is about 15k. Therefore the alternator doesn't necessarily need to larger pulley to slow it down and keep the rotor from uncoiling. Just letting you know what to keep an eye on! Contact me with any additional questions. :cheers:

I have one and have no alignment issues whatsoever. Battery voltage PID reports around 14.0-14.5 during normal idling/cruising and dips into the 13s during a WOT pull. I have less than 100 miles on it but I barely drive the car so that's not going to change anytime soon.
I just placed an order for one today. I voiced my concerns regarding this misalignment issue to Matthew from Mechman, and he says those may have been caused by either using a wrong alt pulley or by improperly installing a spacer(s), that they provide with the unit. So, I dunno. Keeping my fingers crossed.
Btw, I have 2.9L Whipple and stock lower, so I am going with the pulley that they ship it with.

Keep us posted, I want to know what the installation and product quality are like.
still going strong here....quite a few alternator issues this weekend at the track.....MECHMAN
Were you at MIR? DId you come and ask us for a tool with your alternator in hand? I was the tall guy by the black/red GT500!
Are you saying that others had alternator issues while your Mechman ran well?
Im saying 2 or 3 cars were having voltage problems this past weekend at the shootout with oem style units
:nonono:
Exactly why I over build (overkill) EVERYTHING! Especially hard to swallow when traveling hundreds if not thousands of miles to an event only to have such a failure.
Finally received mine (170A Billet Alternators) on Friday and managed to install during the weekend. That thing is build flawlessly! The build quality is top notch and it is pretty much identical to the Autozone unit - will try to upload some images later. It fits right in as a stock unit and aligned perfectly.
It read 14.7 - 14.8 on idle and never dipped below 14.5 for me during some intense driving, WOT pulls and my sound system blasting (lights on too).
Now, I think the question is reliability and only time will tell.
BTW, they attached a paper tag with some in house testing notes and it stated 138A at idle and 178 max for my particular unit.

Awesome. Which model and options did you order? That looks pretty tempting right there. How much did it cost?
This one is 170A model with black anodized finish and internal voltage regulator. I originally ordered machined finish (who cares based on where it is located in our cars) but they had them out of stock so, for the same price, they shipped me the black one. I ordered from Mechman directly for $499 for machined ($525 for black and $550 chrome).
That's vague. Shear off, break in half, break like the OE idler pulley's do? Please explain.
I'll still be taking with a grain of salt considering he run's 8's @ 152 and a 4.0 whipple which puts monstrous torque on the belt system.

I agree it has to do with the Whipple. Ive NEVER had belt slip nor have I ever broken a belt and I always get the belt on by myself with moderate effort, never forced. Mechman has a new pulley on the way under warranty and hopefully a different style nut for it. I'll post some pics by the weekend. Alternator is fine, scratched up, but fine. The aluminum pulley broke.
Sounds like GREAT CUSTOMER SERVICE!
Thanks for clearing that up Jake. Looking forward to pics. Did Mechman say they have a fortified pulley for you?
Heard nothing but good things so far with the warranties.
Cool, thanks for the info. Looks like a direct swap, including the wiring, is that right? I might just bite the bullet and go for one of these, my air compressors draw a lot of juice.
