Racer 5 Clone from BYO Magazine, modified a bit for my system efficiency and also for my Hop AA, I added a 30 minute addition of cascade because mine were lower AA than the BYO recipe so I added a latter addition instead of more at 60 minutes. Figured it couldn't hurt. Turned out great, really good example of West Coast IPA. Adjust hops for AA changes accordingly to get about 68-70 IBU.
