When we left off each of our five builders had the blueprints for the perfect motor that met our rules. Since then we never thought that people would want to do last minute changes based on what was said in our second part of the WD-40 B-series shootout. While we were busy sorting out the last minute changes, a gigantic wrench got jammed between the gears. It turns out that one of the five builders felt that it was in their best interests to pull out of the race. RS Machine is known across the nation for doing a lot of the machine work for most of the top racers campaigning in the import drag racing series'. Considering their machine work is what pays the bills and engine assembly is more like a hobby, after careful consideration they decided to drop out of the competition. Rich Salvador of RS Machine concluded "Since we do some of the machine work for the competitors in this competition and we are a machine shop rather than engine builders, we feel it's not very honorable to compete against our customers."
Now our five tuners dropped down to four and we were left with a decision to make about the spare motor. We could proceed and watch the remaining four battle it out to the death, and we will. But sometimes things happen for a reason and on this occasion the timing was so perfect it could only of meant one thing. We felt it was unfair to pass off the project to some unlucky sole last minute because they would have three fewer months to build it. We also didn't want the brand new Honda block to sit and fester as a dust collector for months to come. Now then, as you have just found out if you read Tunerology, Gary Castillo, Technical Editor for the past five or so years finally gave in to the "grass is greener" syndrome and as of this same month decided to move on and open his own shop Design Craft. So we figured there couldn't be a better home for our orphaned engine than a shiny new shop. Plus, we got the satisfaction of throwing Gary, self-confessed Fabricator/Engine builder, well and truly into the deep end at such a late stage in the game. It wasn't our fault however, the timing surely made this destiny and Gary fell for it. But, at the end of the day, we get to work with him at a different level for another couple of months, and it added another element of excitement to the build up as we watch him scramble to try and overcome an impossible deficit. This is gonna be good!
And so, while we check in with our competitors during the vital cylinder head stage to find out more about individual approaches, Design Craft is on the phone frantically ordering bottom end parts while we're having fun.
