Wayne, In my L20B I have been using optimax with a CR of 10.3:1 and it has been OK so far. Avgas is now pretty much only legal for historic racing at tracks. Pretty much all other classes for curcuit racing will be on premium unleaded next year. Cheers Trev

Now as i am told, AVGAS will be restricted to purchasing by airplane type guys soon, not rev heads. So what Compression Ratio can we use with optimax. The L20b had a cranking compression @ WOT of 240 psi. Now that i have the head off, i will borrow a burett from work and cc the head and bore to get the comp ratio. What are the racers going to do about fuel? or will circuits have a decent fuel supply on tap. anyone? -Wayne --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
