JetArea 3.0 - Blown Fuel System Tuning Software - $380!


JetArea brings sophisticated engine tuning and ET prediction technology into the 21st century and right to the starting line! Windows tablet PC's are now powerful enough to handle all the complicated thermodynamic property equations that must be solved for this type of analysis. And small tablet PC’s can easily be taken into the staging lanes to accurately determine that last minute main jet change and ET prediction. The JetArea software does all this for you and handles supercharged methanol, nitromethane and gasoline fueled engines, and drag racecars of all types.

The weather math and dragstrip physics are all laid out in the "Motorsports Standard Atmosphere And Weather Correction Methods" book. JetArea also includes an option for tuning non-supercharged engines. This feature was designed to work for typical A/Fuel Dragsters or methanol fueled engines (A/ND, Sprint Cars, etc.) with mechanical fuel injection systems.

The JetArea software is specifically designed to work with small touch screen displays, as the need for a keyboard and mouse have been dramatically reduced. However, JetArea also works great on any laptop or desktop Windows PC as well. Anything from WXP to the new Windows 10.

 

JetArea sample program screens are included below for a typical NHRA Top Alcohol Funny Car (TA/FC). There are detailed inputs for your supercharger and fuel pump, along with all the traditional weather station variables. You input all your fuel nozzles, bleed jet diameters and check valve pressures in order to tailor the simulation to your exact fuel system design. Then as the weather changes away from a baseline setup that you like . . . Jet Area will determine what the new main jet should be. Another feature allows you to change the blower overdrive and have JetArea predict the required main jet – this is the way some supercharged Top Dragster and Top Sportsman racers are now tuning.

JetArea also has a complete fuel flow bench simulation for your specific fuel system. FlowBench is more accurate than the data you get from a hardware based flow bench because it includes manifold pressure effects (see the sample FlowBench screen below). This feature allows you to predict the GPM and c.c./turn vs. engine RPM . . . and see the effects of the main jet diameter and bleed jets opening and closing with different check valve pressures. The FlowBench graphs and tables make it really easy to set up your fuel system to deliver exactly the GPM you want at every RPM.

September 2015 Update: JetArea now includes the powerful ETProRx app to predict dragstrip ET for all types of bracket racing. Not only does this new app work seamlessly with JetArea to handle the weather variation, ETProRx also includes the track temperature and wind effects for your specific drag racecar. Check out the last sample program screen below for all the new capability.

The price of the JetArea software is $380 and includes:
- the program CD and a user license to allow installation on 2 PC's

- printed user manual (20 pages!)
- free USPS Priority Mail shipment to any address in the USA

- special offer: add the MSA Weather Book to your purchase for only $40

Nitro Tuner ProRx 1.1 - Supercharged Engine Tuning
A Full-Customized software Service Leased Race-to-Race!


The Nitro Tuner software development started back in 1987 when I was working with Norm Drazy on the design and development of the PSI Lysholm/screw type supercharger for NHRA Top Alcohol Dragster. We wanted to know what the pressures and temperatures were as the fuel-air mixture entered the top of the blower, exited the pie-shaped opening underneath . . . and then made it's way into each one of the cylinders as more and more fuel was added by the port nozzles.

Much of the fuel evaporated along this path and cooled the fuel-air charge prior to getting trapped in the cylinder when the intake valve closed many degrees after bottom dead center. The actual engine/blower air flow rate, fuel-air ratios, and pressure and temperature just before the spark plug ignites the mixture are critical to making the most HP in any kind of engine. We needed a way to accurately "simulate" the entire process of compressing the fuel-air mixture up to moment of ignition.

Knowing what the fuel-air ratio is for your specific engine combination requires knowing both the air flow rate and the fuel flow rate. Every engine tuner measures the fuel flow rate in gallons per minute or c.c./turn with the data recorder. The actual supercharged engine’s air flow rate as the weather changes, or when going down the race track is much more difficult to determine.

Today, NTProRx brings this sophisticated engine simulation technology into the 21st century! Windows PC's are now powerful enough to handle all the thermodynamic property equations that must be solved for this type of complex fuel-air system analysis. The NTProRx software is specifically designed to work with small touch screen displays, as the need for a keyboard and mouse have been dramatically reduced. However, NTProRx also works great on any laptop or desktop Windows PC as well . . . anything from WXP to the new Windows 10.

The NTProRx custom software will handle supercharged methanol and nitromethane fueled engines of all types. Supercharger styles can include both the Standard and High Helix Roots blowers . . . and the PSI and Whipple screw superchargers. NTProRx is a fully customized software setup for your exact engine combination. The TAProRx version is specifically designed for NHRA Top Alcohol and Pro Mod engine tuners.

Have a look at the foursample program screens included below:
    NTProRx for a sample NHRA Top Fuel or Funny Car
    NTProRx for a sample Nostalgia Funny Car
    TAProRx for a sample NHRA Top Alcohol Funny Car
    TAProRX for a sample NHRA Pro Mod

The software includes a “Baseline” engine tune-up column on the left and a new set of “Prediction” weather conditions on the right. You use NTProRx to duplicate the Baseline engine performance in the new Prediction weather. NTProRx is basically a copy machine . . . it ensures that the combustion chamber conditions at the moment of ignition are exactly the same for both the Baseline and Prediction weather conditions. Having exactly same amount of fuel and air in the combustion chamber, at the same thermodynamic conditions, will give you the same consistent run-to-run results, regardless of the changing weather conditions.

A free demo version of the NTProRx (or TAProRx version) software and user manual are also available. Yes . . . that's right! FREE!!! Just send me your email address and I will send the free demo to you. You will be able to install and run the demo software on your Windows PC. Give the free demo a try first before you call to order the full-on customized software version specifically designed for your race team!
