GT-POWER is used for guiding the development of intake and exhaust systems, especially with respect to acoustic performance. The advanced Navier-Stokes based solver in GT-POWER intrinsically captures the pressure wave dynamics within the simulated system. The pressure wave dynamics result in noise being propagated from the intake and exhaust openings of the engine, and GT-POWER is capable of predicting both the levels and quality (frequency content) of the noise from the exhaust tailpipe and intake snorkel. Advanced 3D pre-processors allow for easy integration of even the most complex mufflers, air boxes, and more.
Our famous easy to use 2 stroke expansion chamber calculator by simulation software just got even better! 15 years of development. Work on all capacity 2 stroke engines from a motorcycle to a snowmobile,scooter, go-kart, atv, jet-ski, boat, rc car, rc boat, rc airplane or full size micro light airplane, the wizard design the best expansion. Engine Builder Professional is an easy to use engine building software tool for 8, 6, 4, 10 and 12 cylinder engines. It was developed to allow the user to fully optimize the selection of engine components and engine settings for the ultimate engine build. Header Design Resources. Header Design Resource Page. The following is a list of header design resource that we hope you will find helpful. We are constantly adding to this page, so check back frequently for updates. An exhaust manifold is not the most efficient design, but it is the most simple, most direct, and least expensive method of routing the engine’s exhaust pulses out of the engine. Most exhaust manifolds do not provide an equal length of exhaust flow cylinder-to-cylinder before the individual cylinder gases combine and enter the exhaust piping.
Exhaust Pipe & Manifold Design Software Designing Exhausts and Exhaust Manifolds using Sheet Lightning CAD Software Sheet Lighting CAD software can be used to design customized sheet metal car and motor cycle exhausts and exhaust manifolds and unfold the sheet metal pattern developments for manufacturing the exhaust.
