[TiTiKo]

Hi people i am from Venezuela and we are designing the car to go to the competition the following year, it is our first car, where i can find information about how desing the intake manifold, do you have some document that can help me? about the what throttle use? how desing a throttle, the intake, etc...
the restrictor is 20mm but i have a dude, ¿can I place a Venturi and that the central part (neck) measures 20mm and after it can i increase the measurement until to the plenum?, the primary runners must have a measurement of 20mm?, etc...

Hi, it appears that you really have never seen a FSAE intake at all, so I would first recommend browsing through the many great FSAE websites and looking at photos of cars and engine systems, there is a suprising amount of technical detail on some sites. This will give you a good general idea.

as well

there is a search engine for this forum

there is lots of information already here

hi Charlie off course that I have visited all web sites of some universities, i have seen as are the intakes models, i have some notion about that how to do the intake, but I want to know if you have some information for the design that can give me an important aid... thanks charlie

you might want to invest in an engine simulator that will allow you to design the intake and see how it effects engine performance, such as Virtual Four-Stroke. that's what we use. you can also tune the exhuast in addition to the intake plenum and runners.

Hi Mike Shaw thanks, I have several documents that help me in the design and construction of the intake , where I can find that program? here in the forum? thanks

Sorry, from your description it sounded like you were asking if the restrictor had to be a 'plate' or if it could be a venturi. Which the answer would be obvious if you'd seen a FSAE intake, I guess you meant something else.

Search for 'Ricardo WAVE' there is a thread about that simulation program, which is free to FSAE teams through Ricardo.
