2-STROKE EXHAUST CALCULATOR


Calculate GP / ROAD / Off-Road 2-Stroke exhausts for optimal performance.

Calculate 2 or 3-Stage exhausts.

New OVERLAY feature, calculate 2 exhausts for the same engine, just by modifying some inputs you can compare both exhausts on an overlay chart.

This module also provides results for BMEP, Exhaust Port DX & D1 Width % of Bore, Linear Piston Movement, Cylinder Wall Surface Area, Piston Area and GearBox Coefficient if filled.

2-Stroke Racing Exhaust Design Overlay

Create your own calculated 2-Stroke 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

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.

GEAR BUILDER

Frequently Asked Questions

No
The WINDOWS RacingSM 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 racingsmsoftware@gmail.com and we will talk about a special price for multiple license acquisition.

Windows FULL Package: only before activation, after activation there is no refund as there is no guarantee that you have deleted the software, so make sure you want it before ordering.
Mobile SaaS Package: no refund.

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 ( WINDOWS ) and the SaaS Package with 19 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, 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"

For SaaS Package, check out if your device and browser is compatible.

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 .

Check out your Windows Regional Settings / Language / Keyboard on your Control Panel, it should be something like this:

About

We are 2 portuguese brothers, Pedro and Ricardo, we love and are 2-Stroke enthusiasts.
In 2002 we've created RacingSM to promote our personal 2-Stroke projects and also help others on their bike & engines development.

Developed by Pedro, with more than 20 000 lines of code, all the know-how applied to software comes from us and also a lot from the legendary Portuguese 2-Stroke tuner LUFO Racing, this software is directed for all 2-Stroke:
Enthusiasts, Tuners, Mechanics, GP, Drag Racing, MX, Enduro.

There is no 2-Stroke displacement limit for our Software, for example you can have a 125, 250, 500, 700 single-cylinder and our modules will work flawlessly.
From a 49cc Racing engine, to a GP 125 engine, or a 1500 Mercurial Triple engine, or a 250 Kart engine, RacingSM Software suits all.
We believe that using this software will help your 2-Stroke development or racing results on different types of competition.
At the moment, we have a special 2-Stroke bike collection:
