I called Holley/RacePak about this. They said that in order to get an audible alarm, I would have to use an output from a digital dash to trip a separate relay with some kind of speaker. I think this is beyond me, frankly. I was hoping I might be able to get an audible alarm with a simple data logger. A digital dash is really not what I want for my street car. I will probably just run the extra quart of oil with a simple OBDII data logger and check it after the session. I'm not sure how many seconds of oil starvation would actually cause damage to the engine. My father (old head club racer) thinks the film of oil would take longer than the length of one corner to dissipate. He says I should just let it rock, and he's probably right, but that's easy for him to say as it's not his money 
They use high quality sensors with Metripack connectors and are a FULL SWEEP (270 deg) gauge as opposed to most normal electrics whic are 1/4 sweep (90 deg). They have a peak memory (both low and high) and a built in warning light than can be adjusted to any temp or setting. In addition they have both min and max warnings that can be configured to trip an external warning light, audible alarms or even to turn a fan on. I have my oil pressure gauge set to 15 psi and it is also wired to a red Pro Lite mounted right in front of me--you can see it no matter what!
I especially like the fuel pressure one because you do not need a gauge isolator like a traditional fuel pressure gauge. Autometer makes them in many display styles, I like this the traditional Sport Comp:

I think some of the Autometer gauges are capable of an audible alarm. And I'm pretty sure most of the smart phone OBDII gauges can be configured to do that as well.

You would see the oil pressure gauge shoot up and settle at around 25-30 psi before the engine was actually even started. Doing it like this, the engine always had oil pressure before the first crank.
If there are no leaks in the fittings, lines, or the actual internal Accusump piston, it should hold pressure for 2 weeks if not longer. Mine would go at least 2 weeks of holding pressure. The 2 qt unit was ideal for my 1600cc motor, the 3 qt ones are better for V8s.

I have a drag car (class car) with very restrictive rules so we're looking for any free horsepower available and although I can't comment on a road course, I did see improvements in pressure stability with an accusump. I run 5 qts total with a 1/2 qt filter and a 1.5 qt accusump so 3 qts in the pan minus whats trapped in the engine. During a heads up run I've run 4 1/2 qts so 2 1/2 in the pan. bearings look perfect, I wouldn't do this without an accusump, they work.

I'm bumping this thread with an update for anyone who might be interested in the Improved Racing oil pan baffle. I got a nice email from Mr. George Anderson at Improved Racing. He tells me that the wet sump oil pan baffle (part number for the LS3 in my car would have been EGM-216) has been discontinued due to manufacturing issues. He says Improved Racing is working on a new design (no ETA).
It looks like these people are still selling the discontinued part: https://www.corvetteinnovationz.com/...nk-scraper-kit
I'd be wary of buying/installing it given the manufacturing issues Mr. Anderson noted. I am interested in ordering a newly designed baffle if/when Improved Racing or other vendor designs such a product.

We are not familiar with Corvette Innovationz. They are not listed as a dealer and have not purchased these baffles from us, so it's doubtful they could have any in stock.

We are actually working on a full baffled oil wet sump oil pan for the C5/C6, which will perform better than the baffle. This allows us to optimize the pan's performance without working around the limitations of the design of the stock oil pan. As mentioned it's difficult to provide an ETA at this moment.

Sorry guys, that project has been delayed quite a few times as we've been focusing on other things. But the good news is we just purchased a C6 test car for further development of our oil cooler kits, and we plan on using it to test oil pans as well. So hopefully this project will be moving along this year, but not ETA yet!
