Note: This item looks to be brand new. It comes with a new battery. I installed another battery and it powers up perfectly but I don't know anything about how it works to test it out.



Absolute barometric pressure, relative humidity, and the percentage of oxygen in the atmosphere through its state of the art electronic sensors. This information is transmitted into a microprocessor where density altitude, oxygen altitude, and predicted values are calculated and displayed to incredible accuracy through exact scientific equations formulated specifically for internal combustion engines (verified by authorities in atmospheric research).

A density altitude measurement can easily be off many hundred feet when considering a change in the percent of oxygen in the atmosphere. The optional oxygen sensing capability allows the PerformAIRE to measure the percent of oxygen in the atmosphere. By knowing the density and the percentage of oxygen in the atmosphere the PerformAIRE can calculate the exact amount of oxygen in the atmosphere, which directly relates to performance. The PerformAIRE computer contains a data base that allows for storage of runs and then uses this data to automatically predict ETs, Throttle Stop Settings, Jet Sizes, etc. The predicted values are continually updated with each new sample of air. The density altitude and oxygen altitude will automatically be stored with each run if an oxygen sensor has been installed. The stored runs are also tagged with a time and date stamp to allow for later referencing. The expandable data base is capable of storing hundreds of runs and will allow those runs to be stored in separate data bases, which can be labeled for specific cars or tracks. The PerformAIRE V6.0 is packed with the same prediction capabilities as the original PerformAIRE, but also allows for 1 run predictions with preset and user defined ratios, multiple weather variable predictions (density altitude, oxygen altitude, air density ratio, correction factor, dew point, and vapor pressure), and corrects prediction for wind effects, which are customizable. The PerformAIRE computer's data base can be downloaded into a PC. One click of a mouse can download the data directly into a spreadsheet where the runs will be automatically charted showing a visually relationship between your cars performance and the changing atmosphere. This allows for the easy removal of bad runs from a database and more accurate predictions.
Besides all the added features and ease of use, there is one main reason why the PerformAIRE air quality computer is superior to all other weather stations/calculators. First one must ask themselves, what is the most important capability a weather station must possess. Hope you would answer the ability to accurately and repeatedly measure the atmosphere one is racing in. A weather station without this quality is useless. Detecting small changes in the atmosphere or using inaccurate measurements can be the difference between winning and losing. As little as a 100 foot change in density altitude can noticeably change the performance of an automobile. Most racers do not realize that a minor change in the atmosphere can equate to a major change in density or oxygen altitude. On average, a 1degree change in temperature, a 0.1 inHg change in pressure, a 10% change in humidity, or a 0.1% change in oxygen can be more than a 100 foot change in altitude. Instruments being used in other weather stations have variables that make it impossible to measure the atmosphere at a level needed to predict the performance of a racecar. These inaccuracies can stem from a persons inability to correctly distinguish what the instrument is reading, the effect temperature has on the instrument, and the instruments accuracy/repeatability ratings.

Peugeot RCZ revealed

Mon, 17 Aug 2009 00:00:00 -0700

Peugeot has finally released details of the Peugeot RCZ, which will launch at Frankfurt Despite our previous criticisms that the Peugeot RCZ looked like a clone of the old Audi TT, we think it’s a great looking car. It’s a real statement of intent to push Peugeot more towards the ‘Sporty’ and leave Citroen to do the ‘Luxury’. And it looks set to cost less than £20k (as a starting point) when it finally goes on sale next Spring after an official reveal at Frankfurt next month.

New Porsche Panamera GTS takes to the track (video)

Sat, 19 Nov 2011 00:00:00 -0800

New Porsche Panamera GTS takes to the track The new Porsche Panamera GTS is the latest Panamera variant to arrive – the ninth Panamera, no less – and is, as all Porsche GTS models are, a harder-edged take on the more mainstream variants. With its naturally aspirated 4.8 litre V8 producing 425bhp, and pushing those horses through a PDK ‘box to all four wheels, the Panamera can scoot to 62mph in a very respectable 4.5 seconds on its way to a top speed of 179mph. Not bad for a big saloon car that eschews forced induction and can carry proper-sized passengers in comfort.

2013 VW Golf GTI MK 7 revealed

Wed, 26 Sep 2012 00:00:00 -0700

We have the first photos of the 2013 Vokswagen Golf GTI – the MK VII GTI – ahead of a debut at the 2012 Paris Motor Show. It’s just over three years since the MK 6 Golf GTI arrived and now – ahead of what was expected – we have the reveal of the 2013 VW Golf GTI MK VII. Heading for the 2012 Paris Motor SHow this week, the new Golf GTI holds no real surprises – it’s the MK 7 Golf with the usual GTI appendages.
