F500 Rule Changes
Posted by: edc on Thursday, April 20, 2006 - 10:47 PM
SCCA Rules

It seems that the rule change proposals originally developed, discussed and incubated here on the F500 mailing list are making some headway. The following actions on some of these proposed rules appeared in the May 2006 FasTrack:


Item 1. Effective 11/1/06: Add the following to section 17.1.6.E.15.g:
Rotax 494 and 493 engines: Any Rotax 494 or 493 respectively model thermostat housing or water outlet may be used. The water bypass may be blocked.


2. F500 - Remove the weight penalty from the 493 (various - 5 letters). The weight is appropriate as listed.
3. F500 - Allow Kawasaki engines unlimited porting (Wilson). We agree that the Kawasaki engine requires assistance; however, porting is not consistent with F500 rules. See technical bulletin #06-05 for weight reduction adjustment.

And Technical Bulletin #06-05 reduces minimum weight for Kawasaki Engines to 700 pounds:

1. Section 17.1.6.E.2, change the first paragraph to read as follows: Minimum weight as qualified and raced, with driver, shall be 700 lbs (800 lbs for AMW and Rotax 494 engines, 850 lbs for Rotax 493 engines).
Other items are still under consideration and there will be more discussion and further input requested on several of them.
