It will have in account your gearbox ratios if provided and alerts if Exhaust Port width is too large with piston ring failure.

This module also provides results for BMEP, Max EGT, Exhaust Port Width % of Bore, New Exhaust Port Width, Cylinder Exhaust Port Diameter

THREE STAGE EXHAUST CALCULATOR

Calculate optimal 2-Stroke exhausts based on the famous G.P BLAIR 2-Stroke tuner.

LuFo Racing Exhaust Design Overlay

Create your own calculated LuFo Racing Exhaust System Design Database with this module.

2-STROKE EXHAUST SEGMENT SPLITTER

New feature of RacingSM Software, the 2-Stroke Exhaust Segment Splitter.

Split your calculated 2-Stroke exhaust up to 42 sections with regular length or even more with irregular lengths.

Great tool for those who are building exquisite format exhausts, one of the largest benefits of this module is that it can be used with any Exhaust formula results ( LuFo, Blair etc )

EXHAUST PORT DURATION CALCULATOR

Calculate your Exhaust Port Duration given a certain Stroke, Connecting-Rod Length, Distance to Cylinder Top and also Deck.

BIKE DYNAMICS

One of the most important features of RacingSM Software is the BIKE DYNAMICS module.
Here you’ll be able to compare 2 bikes with different specifications in order to analyse the results and possible differences obtained.

Results:

  • Thrust @Wheel @Each Gear Vs Resistance Air Force
  • Real Speed 5th & 6th Gear and necessary Rear Wheel Horsepower Vs Dyno Values filled
  • Gear Ratios Gaps between Gears
  • RWHP & Torque Vs RPM & Real Speed Chart
  • Acceleration Chart @ Each Gear Real Speed
  • Real Speed @ Each Gear on all RPM band
  • Elapsed Time Statistics & Predictions
  • Distance - Time Vs Speed Performance

This simulator is specific for straight line acceleration on drag strip or road, there are a lot of input data which must be accurate in order to obtain also accurate results.
You can compare 2-Stroke and 4-Stroke bikes.

GEARBOX ANALYSIS

This module allows the study of gearboxes and know how a gear ratio change can affect the bike performance.
This is particularly useful for those who GP race, because depending of the Circuit, the modification of secondary transmission might not be enough and it would be considered the change of some gear ratios.
Without a tool to immediately know how a change affects, it's very difficult for a tuner / mechanic to know how the bike will run.

Another very useful feature is the ability to fill with your Dyno Curve values, your current secondary transmission, rear wheel dimensions, the CdA aerodynamic coefficient and the module will calculate real speeds and necessary rear wheel horsepower on 5th and 6th gear and compare with your Dyno Values.
If you have enough rear wheel horsepower at a certain real speed, a green cell will appear, if the value is almost there, an orange cell will appear, if it simply doesn't have the necessary horsepower, a red cell will show.

You can calculate the gaps between gears, understand if it's GP, Close-Ratio, Street, Wide gearbox and how it affects on real life performance with calculated real speeds given a certain transmission, RPM, Aerodynamic, weight coeficients.

CARBURETOR TUNING

Easily rejet your carburetor after atmospheric condition changes and / or altitude.

This is particularly useful for those who GP race or do Off-Road, depending of Circuit altitude and temperature the jetting is affected and needs changes.

CYLINDER HEAD DESIGN

Great for those who use programmable Ignition setups ( Zeeltronics, Ignitech etc ) and want to create a complete ignition curve.

CONNECTING-ROD ANALYSIS

Simulate based on different RPM regimes, Stroke and Connecting-Rod Length the Piston G-Acceleration, Rod/Stroke Ratio, Con-Rod Attack Angle.

CLUTCH TORQUE

Calculate the maximum Torque a certain clutch can hold undergoing uniform wear.

VESPA SIMULATOR

If you are a Vespa enthusiast or if you race your Vespa, this module is for you.
The VESPA Simulator allows the owner / racer to previously simulate various gear ratios and obtain real life performance ( real speed in each gear depending on RPM, total weight, road slope and rear wheel ).

VOLUME AIR & FUEL FLOW

Use this module to Calculate Air Density and Dyno Correction Factor.

DYNO CONVERTER & OVERLAY

This module is useful if you want to store a dyno database or particularly if you intend to convert Torque Units ( from Nm to kg-m etc ).
It's also possible to Overlay 2 Power & Torque curves on a chart to analyse their differences.

BMEP Calculator & DATABASE

Frequently Asked Questions

No
The Software is sold per license, you can only install it on 1 computer / Hard-Disk. If you install it on different hard-disks, it will only work on the one which the Activation was made, so choose wisely on which computer you will install.

Send us an email to orders@racingsm.org and we will talk about a special price for multiple license acquisition.

Well, this has always a subjective answer.
If you analyse the competition, not only they offer a lot less features, but their prices are similar than this complete Software with independent 27 modules/programs.
RacingSM Software has features for many different areas (2-Stroke Exhausts Development, Drag Racing Features, Simulators, Carburetor Tuning, Connecting-Rod Analysis etc)
With all this Know-How along with LuFo Racing heritage, we believe this is a very fair price.

Of course!
Check out all our modules, each one of them can help you develop your 2-Stroke bike/engine in order to improve performance along with good reliability

Of course!
RacingSM Software has some specific modules that can help tuners/builders on their race engines/bikes in order to improve performance and reduce lap times.
Build 2-Stroke exhausts with LuFo Racing philosophy, know how to change gear ratios depending on racetrack, simulate real-world performance with our Bike Dynamics Simulator.

Most of RacingSM Software modules have the SAVE option where you are able to save your data in files which can be opened later.

First check our Minimal Requirements, if your computer has all the requirements:
Try install the .NET Framework 4.0, which is provided on your package with the filename "dotNetFx40_Full_setup.exe"

No.
Due to high complexity of the different RacingSM modules which envolves a big UI (User Interface), it's not possible to contain all data/results on the actual Smartphones / Tablets display.
This will be a Windows Software only version.

Sure.
But before sending us an email or Facebook message, please read carefully our User Manual that is provided on the package or here on our website.
Probably your questions will be answered after reading the User Manual.

The best answer is:

GIGO stands for “Garbage In Garbage Out”.

What this means is that we can’t expect to get better quality results than the quality of the data that we input. Having said that it is true that some parameters only have a small influence on the performance and so the accuracy of those parameters is not critical.
Some of the required input data is easy to come by but other data may be difficult. Internet, magazine road tests and manufacturer’s manuals are a good source of some data.
The following will consider each piece of data individually and discuss its importance and availability .
