Well, it has been quite some time since there has been a post here! Apologies for that. I do owe you guys photos and fun from several different builds we have been working on. I will get to posting those…eventually. 😉
Rules changes have recently been a hot topic among the 11 guys, and if you would like to see how hot it has become you can visit these two threads on the Class 11 Coalition: Aftermarket Shifters (discussion started here), continued here SCORE Rulebook Updates Happening.
SCORE recently made post regarding the changes for Class 11, Class 5/1600, and Class 1/2 1600 (as seen here: http://score-international.com/11-5-1600-12-1600/)
Statement from SCORE Tech director, Art Savedra,
After almost two years of watching this 8-to-1 low compression engine combination compete against the High compression engines I have seen a very competitive new introduction and a need for a change in the 1600cc Class rule. I am talking about 1/2-1600, 5-1600 and Class 11 here at SCORE International Off-Road Racing. I now see the need to add a different way to race in this class and still be competitive, this is not a change in the rules, but a different way to build your engine and still be able to race.
As of the SCORE Baja Sur 500, these changes will be in effect.
Good luck, Have fun, and Be careful!!!

1/2-1600, 5/1600 and Class 9 and 11 are effected by the wording OR NOT WORDING that is in the 2011 – 2015 SCORE rule book. The wording should read as;
1) NOT ALLOWED – TITANIUM VALVES IN 1600cc ENGINES
2) ANY SINGLE VALVE SPRING ALLOWED…..”CONICOL or BEE HIVE” SPRING ARE ALLOWED.
3) STAINLESS STEEL VALVES ALLOWED
4) MOFOCO HEADS HAVE BEEN ALLOWED AS STOCK REPLACEMENT HEADS
CLASS 11 with the introduction of the “8.0 to 1 Low compression engine” in to this class as an option. There will be a temporary rule modification until SCORE Tech director can find an air box that will work under the stock rear deck lid rules along the Class 11 shifter and bumper rule they will read as;
1) HOOD EXTENSIONS ARE ALLOWED ONLY TO THE “LOW COMPRESSION” ENGINES VEHICLES UNTIL SCORE TECH DIRECTOR FINDS A WORKING AIR BOX.
CUTTING OR TRIMMING OF LOUVERS OR AIR VENTS UNDER REAR WINDOW IS NOT ALLOWED. THIS RULE APPLIES TO 5/1600 ALSO.
