The air horns I used/use on the L20B are about the same lenght as the ones on the inside of the sss box for the SU's. I wasnt thinking of using a filter anyway. Plus with the plumbing it will be forced intake, The air box for the Leopard (4.1) is about 7-10 liters going by the 4 liter size of a box of ice cream.(looks that way)

A good example of a plenum is the "Technicar" >>air plenum on Alfa's with Webers-Dellorto's although it doesn't use ram >>tubes. A quote worth noting is by Julian Edgar in 21st century performance >>"the air intake system cannot be oversized" (pp120). >>Cheers >>Feral Errol >>[EMAIL PROTECTED] >>http://www.datrats.com.au/ >> >>-----Original Message----- >>From: [EMAIL PROTECTED] >>[mailto:[EMAIL PROTECTED]]On Behalf Of nat P. >>Sent: Tuesday, 18 June 2002 1:29 AM >>To: [EMAIL PROTECTED] >>Subject: AirBoxes!!!!! ! >> >>Morning all!!!! >> >>Has anyone made an airbox for twin webbers?
