From January 2010 Fastrack—I think this is mostly what was expected for this year, but in case you weren't aware...
FV: Intake manifold rules will remain the same for 2010 as they were for 2009 as approved by the BoD and published in April 2009 Fastrack. (Section 9.1.1.C.5.D.20 of the updated GCR).
An FV ad hoc committee is preparing proposals for presentation to the Formula and Sports Racing Advisory Committee. Their recommendations to the CRB will be published in a future Fastrack for comment by the FV community to determine the final 2011 manifold rules. Those recommendations may take the form of additional measurements to be employed in determining compliance of FV manifolds or the institution of a spec manifold.
This advisory is to inform the FV community that there will be changes in the rules for 2011; this information should be taken into account by competitors in 2010 with regard to existing manifolds and any purchases of new manifolds.
