hi, my brother is doing a efi setup ona 360 chrysler, and the guy from CAPA and MOTEC both said to have a air box about the size of cubic inches of the engine. to have a box 2.5 times the engine volume would have to absolutely humungus, on this type of engine.. i totally disagree that haviing a box cannot be oversize ( e.g "the air intake system cannot be oversized" (pp120).). what about
air speed amongst otther things? mark k > ----- Original Message ----- From: "Mr-Freeze" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, June 18, 2002 3:49 PM Subject: Re: AirBoxes!!!!! ! > good quote there Errol > How true too > > Peter > ----- Original Message ----- > From: "E Smith" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Tuesday, June 18, 2002 8:37 AM > Subject: RE: AirBoxes!!!!! ! > > > > Nat, > > Plenum volume should be at least 2.5 times engine capacity (ie 5 litres > for > > a 2 litre engine).
