Venturi

The Just Engines’ J’EN Venturi.

Sized similarly to the chart used by P.A.M.P.A.

Hundreds of users Worldwide.

Seen here on a ASP S15.

Notes:
O.S. Needle Valve assembly can be adjusted and wound in or out of the Venturi body – which changes the effective venturi area and therefore allows your setup to be ‘tuned’ without further drilling or filing!

‘Dork’ tube – a piece of silicon tube, can be added very easily to top of Venturi, which helps stop dirt getting into the venturi (and engine) in the event of a crash (note indent machined in body to accept the tie wrap).

Standard size options:
