BLOWNBLUEZ06@RKT Performance

Many of us have grown tired of having under-performing alternators on our Corvettes. In the middle of the summer, pulling up to a stop light, both radiator fans going, A/C on high and you barely have enough voltage to keep your battery charged.
The factory Valeo is rated at 140 amps in most cases, but that's a best-case and not a full-operating temperature scenario. At full temperature and at idle, we're lucky to get even half of that 140 and lucky to get any decent voltage out of it when it's under load. It's simply not an efficient design.
Billet-Tech has engineered alternator that eliminates ALL of these issues. They are designed using the latest and greatest in alternator design, which has greatly increased the low-RPM efficiency and output. They are available for the 97-2012 Corvettes. The LS6 design with standard clearance is the same case all the way up to 2012





Here's what Billet Tech says about their design:
"

The 6 Phase Advantage

Billet-Tech alternators employ cutting edge alternator technology not found in other aftermarket alternators. 6 phase hairpin stators make Billet-Tech alternators fundamentally more efficient than other aftermarket alternators. This new technology and increased efficiency equates to incredible output at extremely low engine RPM, less energy wasted in the form of heat, and more horsepower to the wheels. Also, because less heat is being generated, the internal components of Billet-Tech alternators last longer. This is especially beneficial on turbocharged and/or endurance racing vehicles with high engine compartment temperatures. All Billet-Tech alternators feature soldered stator and rectifier connections, with epoxy re-enforced stator connections, reducing the chance of vibration failures.



Billet-Tech units are built exclusively with precision balanced low-mass rotors that allow them to operate safely at shaft speeds of 20,000+ rpm. This high RPM capability, combined with excellent output at idle, gives the user a much broader operating RPM range, and more flexibility in the size of the crankshaft pulley used. A properly selected Billet-Tech alternator can even fix low voltage problems caused by using small diameter, or "under-driven" pulley ratios. The higher pole count in the rotor also results in less electromagnetic interference to cause problems with radios and other electronics.







As a final precaution, Billet-Tech alternators are constructed with twin high efficiency cooling fans, and twin internal rectifier plates. While other high performance alternators have only one rectifier with 6 diodes, Billet-Tech units boast 12 press fit diodes with 300% more surface area to dissipate heat. These considerations to cooling airflow and heat dissipation make Billet-Tech high performance alternators the most durable aftermarket alternators you can buy. If you are experiencing premature alternator failure, intermittent electrical accessory problems, or low voltage at any engine RPM, a Billet-Tech 6 phase alternator is the answer!


"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.
4 finish options offered: Machined, black anodized, polished and chrome.
2 outputs offered: 170amp, 240amp
2 Case options. The LS1 C5 case will provide up to an inch additional clearance for those members who could use the extra clearance due to taller valve covers or a modified coil mounting configuration.
The standard LS6 C5 case will sit down closer to the valve covers, providing the same clearance as the factory Valeo alternator.

Also available is the AVBM, which is allows you to adjust the alternator output voltage.

The last thing I'll share with you is a 14volt option. This involves the use of a 14volt AGM battery Excess Power battery, an external regulator and a custom alternator. The charge voltage for this system is around 17.5. What I can tell you is that there are many GM vehicles running around with this system with 0 issues. Billet Tech has a number of vehicles that they successfully tested before offering this special option. If you think you may benefit from this option, contact me and we can discuss it.

the Corvette will benefit greatly from the 170amp.

Billet-Tech has tested and compared their alternators to our factory units and their 170amp alternator will typically produce +1 volt and supply an additional 80 amps at full temperature, at idle speeds. In other words, the 170 will be more than enough to supply the Corvette with good voltage and have enough in reserve to support up to a 1500 watt stereo system.
Be careful when selecting your alternator. It takes more than most are aware of to drive a high output alternator. Unless you have a specific need to choose an alternator beyond 170amp, I would recommend that most choose the170amp model. Their low-RPM performance is significantly better than the higher amp models. It's a "give and take" situation and considering where most of our engines spend their time, 170amp models will be the most suitable choice.

Considering what a factory rebuilt alternator costs, this is definitely the better, smarter choice.

Those with 2000 and older please read below:
I need to get some answers on the pre 2001 alternators. I will stand behind what I sell, but I've been advised of an issue with the alternators triggering a DIC "charge fault" message. Although I was told by the Billet Tech alternator engineers that it won't be an issue, I need to confirm that with an actual sale.
Here are some examples of the Corvette models:

outkast6991

Pm me a price for an 01 a4 coupe please

MSG C5

Waiting for ET's input on this thread.

kasper-pA-

Could you PM me a price on the black anodized 150a and 170a.

Evil-Twin

OK so what you are saying is that you have different discriminator circuits built into these units to some how fake out the early model C5's from the late model C5 where the PCM is looking for specific generator spooling between specific parameters and then recognized the switch over to alternator circuitry so that the "Charging System Fault" is not tripped and displayed on the DIC.? That's great if you can pull that off, especially for the early model C5's, the ones with a 110 amp output.

c5vetteguy

Me too, please.

WKMCD

I looked into upgrading the alternator on my car when I did the sound system and kept running into that issue.

BmoreRnsDeep

Can you list prices for the different outputs instead of PMing people?

Maxx_Z06

Same here. Send me a pm please.

BLOWNBLUEZ06@RKT Performance

You must me the afore mentioned ET
These are plug and play units. No adapters involved, internally or otherwise involved in making these work. These are built here in the USA and you can expect great support.
They are promising no issues here.

Evil-Twin

I've been addressing this for 12 years here.

Vert'd Z0

pm a price for the standard 150 amp in both machined and polished finishes, please.

thanks....

3318C5

Email sent on the 150.

PETE O.

Do these come with the correct drive pulley in the correct diameter for belt length. Please PM me the price of a black anodized one in 150 amp.

LoneStarFRC

Same here. You CANNOT just take a 140 amp (or higher) unit and slap it on the '97-'00 cars without the constant "CHARGE SYSTEM FAULT" warnings. Even this company's website says "for '01+ Vettes"

BDTD a long time ago.

Evil-Twin

so what you are saying is when the alternator puts out more than the PCM is looking for that it is not going to throw a fault. We threw in this discriminator circuit to communicate directly with the PCM to monitor is output during initial startup while in generator mode then switch over to alternator so any problems with the charging circuit could be identified. The C5 Alternator is not one that can be altered to a different output without a factory re-flash to the PCM and only after that specific alternator is designed to communicate with the PCM algorithms. The C5 alternator is an alt/gen. So you are saying you can put in your 170 alternator into a closed loop circuit that expects to see either 110 amps or 140 amps and the PCM is going to be ok with that even though its designed to pick up any variables above or below that 110 or 140 unit. Id like to know how that is done. IM assuming you don't have different alternators for different Vin numbers for C5's. IM not trying to give you a hard time but, IM here to help protect the membership from grief.

PNW Vett

Thanks for looking out for us once again Bill!

BLOWNBLUEZ06@RKT Performance

Done.

BLOWNBLUEZ06@RKT Performance

I'm sorry, but you have me a bit confused. When you say "We threw in this discriminator circuit to communicate directly with the PCM to monitor is output" Who's we? It's obvious you've done your homework on this and what I'll tell you is that I am honestly not aware of this issue.
Although I'll agree the PCM can look for an output signal and measure that in many ways, that output signal isn't going to be measured in amps.
When Billet Tech listed different alternators for the C5, the differences show to be in the case and not in the internals. I will get with their engineers for a more thorough response.
I have absolutely no interest in inducing any grief in the lives of our members. I will work with the good people at Billet Tech to make sure their product is compatible and if for any reason a member has an issue that cannot be resolved, I will make sure Billet Tech is willing to issue a complete refund.
Thanks for your input.

BLOWNBLUEZ06@RKT Performance

I appreciate the input guys. As I mentioned, I'll work on this.
