The official home page of our 2 stroke wizard tuned pipe calculator 4stroke header wizard calculator software.
The software equations used are derived from the work of Professor Gordon P Blair who carried out the most comprehensive scientic study of 2 stroke. Read my expansion chamber theory page to get a full understanding of how expansion chambers work and click here to read more of the details of this spreadsheet calculatortheory page to get a full understanding of. Got this link from Andy pointing to a software program called amazingly enough Cone Layout.
Free download here. - very fast and efficient design tool. Moreover you can have advices for the development of the engine thanks to the help of tested formulas for intake exhaust.
In version 28 there is no such limitation. Method 1 and method 2 two. Supported units are meter inch foot yard radians degrees.
Four Stroke Design is the ideal tool for technicians and engine tuners to have quick and precise indications on how to optimize the intake and exhaust geometries and the engine valve timingIn fact in order to maximize the performance in the desired direction a specific sizing is required and the geometries identified must match the engine valve timing perfectly which is why the. Bimotion 2-stroke software has been commercially available and in professional use since 1991. The all new 4t tuned inlet exhaust header wizard calculator software version 48 Header Wizard Calculator is an easy to use 4 stroke tuned header calculator wizard.
Two Stroke Design instead you can enter the data of your cylinder with extreme facility and precision and then analyze the port areas and the timing area in the engine cycle timing for each phase. Blair from the book. Also it depends on the temperature and thus on.
Just a quick update on the progress of the freeware 2 stroke Expansion Chamber Calculator SoftwareA few things left to do to itDownload it here httpbird. But because of the limited worldwide activity in two-stroke engine development program sales were limited and further development was curtailed. This small Java applet uses design rules according to and to size a tuned pipe for a 2 stroke piston engineThe calculations are assuming a speed of sound in the exhaust gas which is not known exactly.
The basic principle of the tuned pipe is making use of the moving air masses in the exhaust to assist in the scavenging the process whereby the exhaust gases are removed and replaced with un-burnt mixture of a 2-stroke engine. Thanks to the software. For engines with ignition timing.
Weld the sliver back on to the same piece of. Cut the pipe straight through. 2 The exhaust pipe of a two-stroke engine attempts to harness the energy of the.
On one side starting at the widest point of the circle the diameter in the direction you want the pipe to bend cut off a sliver at the angle you want the pipe to go. A simple 3 stage two stroke exhaust calculator based on formulas of GP. Click here to download a spreadsheet that will let you figure out your engines exhaust pulse time duration.
It is primarily a 4 stroke header calculator program and it does calculate the best performing header specs also features tuned inlet lengths dimensions matching your engine.
