BLOWNBLUEZ06@RKT Performance

The Billet Alternator design for 2015 has not changed, but the pricing has. Still using the 6-phase stator, 12-pole rotor design.

This alternator is compact and powerful! This case design even fits aftermarket heads with elevated valve cover rails using Katech valve covers. Many Corvette Forum members are running this alternator and some have reported that some, if not all of their troublesome electrical gremlins have been eliminated due to overcoming the voltage deficiencies that plague the Corvettes. Low voltage issues in summer stop-and-go traffic? Gone with this upgrade. Stock alternators heat up and are unable to even produce anything close to their rated output. This design incorporates higher efficiency and better cooling to keep the alternator output voltage high, even in higher heat situations.

"So what is there to gain from using the Billet-Tech alternator over the factory original?"
Better system voltage. "So what does better system voltage gain me?"
Many of the electrical components in our cars will perform better with full voltage.
Our ignition coils, fuel injectors, fuel pumps, cooling fans, electric water pumps, headlights (and the list goes on) will all perform better with better system voltage.
Why go with a Billet-Tech alternator over others? Take a good look at the cases of the competitors and you will notice that none of them have the beefy, stronger ears that Billet-Tech provides on their cases. Instead, you'll find some skinny ears with pins pressed in. These are modified cases, designed for another vehicle, modified to fit our cars and not nearly as strong.

Update to the sale thread:
In addition to the alternator upgrades, I’m offering a new 1/0gauge hot bypass cable.
Over the years, I've tested many C6's and investigated many alternator failures. In conclusion, I've found a significant # of cars with massive voltage drops on the hot side. If you want to know if your car is one of them, take a volt meter. Run your car to full temp with the hood closed. Keep it running and turn on all the electrical items that you can. A/C on high, high beams etc. Then take your volt meter and measure from the output lug on the alternator to the mounting bracket or clean, shiny metal on the alternator (no anodized parts). write that # down. Then move to the passenger side and measure from the power distribution post at the fuse/relay box to chassis ground. Write that # down. Then go to the battery and measure across the posts. Not the terminals, but the actual posts. Write that # down. If the voltage at the battery is .3v less than the alternator measurement, then you have a problem. I've been finding drops of over 1 volt lately and the greatest drop has been on the positive side between the alternator and the power distribution post. What I've been doing to solve the problem is running a 1/0 gauge copper (not CCA) wire directly from the alternator output to the power distribution post and cutting the other cable off the alternator. How much there is to be gained is determined by how much drop you're experiencing from the alternator output to that power post. If you take your volt meter and touch one lead to the alternator output and the other to the power post (with the car still running and all the accessories on), it will read the actual amount of drop you're experiencing. Running the new cable will reduce that drop down to as low as .1v.

I'm offering these cables to anyone that doesn't want to build one on their own. I'm using good, high-strand 1/0 copper welding cable and covering it with a nice, nylon braid and heat shrink at each end. 99.00 with your alternator purchase and 115.00 shipped when purchased separately. Let me know if anyone's interested.

I really like mine. It solved my underdrive pulley issue!

WhiteDiamond

The billet black one I got from you has been in basically a year now. It has solved all the electrical issues I was having before its installation. The BEST mod to my Z06 that doesn't involve HP

BLOWNBLUEZ06@RKT Performance

That's what I love to hear! Thanks for your purchase and feedback. I appreciate it.

RamAir972003

Nodded Z with heads and pretty choppy cam.. What amps do you think will be enough for car..

EnginerdVT

How much smaller is the body of this alternator than stock? I just put some valve covers on my car and had to clearance the alternator fins to get it fit. I want to make sure this would give me NO clearance issues and I would order the black one. Thanks!

timd38

Call these guys. They make a spacer.

EnginerdVT

Great call tmid38... I looked for something like this and never did find one. I'd still like to know how different in size the billet tech ones are...

BLOWNBLUEZ06@RKT Performance

170 will be plenty.
I know the diameter of the stock alternators vary, but I can tell you that these have the same center as stock and a 5.285" body diameter.
Here's a CAD rendering of it. The green one is OE and the purple is the Billet tech. I was just telling someone else that I've got MAST Motorsport heads with a 1/2" raised valve cover rail and Katech valve covers, the tallest valve covers I've seen and no fitment issues. I've never had anyone with fitment issues, so if you end up having them, that'll be the first ever with this later design case.

EnginerdVT

It was me but I'm just scared that I buy this awesome black alternator and have to modify it to fit. Not sure I'm willing to take the chance but if it did I'd order it.

BLOWNBLUEZ06@RKT Performance

Tape it up. Set it in place carefully so as to not scratch it at all. If it doesn't fit and is returned in new condition, I'll refund your full purchase price and even risk the cost of shipping if you'll pay return shipping.

Hi!

Your post was a good trigger to add some of your alternators to the Z06 OEM and Aftermarket Parts weight list.

Maybe you can help me to briefly answer a question.
Apparently there are two similar but slightly different websites that are relevant, i.e. www.mechman.com (this is the one that you are referring to in this thread) and www.billetalternator.com.

On the HOME > ALTERNATORS > CHEVROLET > CORVETTE page of the second website I see four 370 AMP alternators, two of which weigh 16 lbs. and two of which weigh 18 lbs.
Apart from this [weight] I cannot detect any obvious differences (apart, of course, from the machined/polished finish). My question: what do I miss here?

Thanks in advance!

Ronald

EnginerdVT

Great offer... I will be back up at the car this weekend to finish up a few things. Once I'm done and I see how bad the current trim job finishes up, I'll PM you if I want to go ahead and do it now. Sad part is that now I'll have to clean up the stock bracket to sit next to this gem!

BLOWNBLUEZ06@RKT Performance

If while you're at the car, you want to compare measurements between the Katech and Proform valve covers, PM me and I'll send my cell phone # and we can cover that.

BLOWNBLUEZ06@RKT Performance

Hi Ronald,
Good questions. The rotor is larger and heavier in the 370 amp model and should have a larger case. Billet tech is a line that Mechman owns.

Z06Ronald

Thank you for your reply.
Yes, I can understand that a 370 amp model has a larger and heavier rotor and case compared to the lower amp models.
But SKU B7864370M and SKU B8172370M are both 370 amp, are both priced at $699 and at first glance seem identical to me in all other aspects too. Yet B7864370M weighs 18 lbs but B8172370M weighs 16 lbs. So that's still puzzling me ..

BLOWNBLUEZ06@RKT Performance

Yeah, I'm not sure. I finally broke down and bought a shipping scale and weighed one of these billet tech 170 amp alternators. It came in at a mere 13.2lbs.

EnginerdVT

Is there a polished bracket or billet bracket that can be purchases with the alternators? I have been looking with not much luck. I have considered buying a stock bracket online and having it polished so I can do a direct swap. Any help is appreciated. Thanks!
