Rave valves shall be locked in the âfull openâ position or left as delivered. No ther alterations are permitted. 494 Rave and non-Rave parts may not be nterchanged between the two engines unless specifically noted.â t looks like the SCCA is wanting to allow the 493, 494 on-RAVE, or 494 RAVE motor all at the same weight. I think the 94 non-RAVE is right in line with the 493 RAVE motor, but the 494 AVE...hoo-whee! The SCCA plans to restrict the RAVE motor to he milder non-RAVE rotary valve, but that's not going to cut the power ll that much. I would take an extra 20 degrees of exhaust port uration and RAVE valves any day, even if I had to give up 12 degrees of otary valve timing. I know we are searching for more available otors, but the 494 RAVE as proposed (without the dreaded weight penalty) ill most likely become the only motor to have - that puts us back to ne. Perhaps the first try would be to add 50 lbs to the 494 AVE   The SEB is soliciting comments. I ave sent mine. _______________________________ ormulaCar Magazine - A Proud Supporter of Formula 500 he Official Publication of Junior Formula Car Racing ubscribe Today! www.formulacarmag.com or 519-624-2003 ________________________________ _______________________________________________ 500 mailing list - [email protected] o unsubscribe or change options please visit: ttp://f500.org/mailman/listinfo/f500 ** Please, DO NOT send unsubscribe requests to the mailing list! *** ________________________________________________________________________ Check Out the new free AIM(R) Mail -- 2 GB of storage and industry-leading spam and email virus protection. ________________________________ FormulaCar Magazine - A Proud Supporter of Formula 500 The Official Publication of Junior Formula Car Racing Subscribe Today! www.formulacarmag.com or 519-624-2003 _________________________________ _______________________________________________ F500 mailing list - [email protected] To unsubscribe or change options please visit: http://f500.org/mailman/listinfo/f500 *** Please, DO NOT send unsubscribe requests to the mailing list! ***
