Sierra Sierra EVO Pre-WTAC 2011 Update
POSTED 28 July 2011 Last Updated on 22 October 2012 

The World Time Attack Challenge is coming up pretty fast next week on August 5 and 6. There have been some changes made to the EVO since winning the 2010 Source Interlink Superlap Battle final at Buttonwillow, but we've been pretty quiet about updates mostly because we've all been pretty busy concentrating on other things.

Mike, Jet, Richard, and Ron have been able to squeeze in some work between the Ferrari races and I've been able to get up to Sierra Sierra a couple times for some engine testing in between my 900 other tasks and travels. The results are pretty cool I think considering what little time we've been able to spend on the EVO. Will the changes be enough to fend off the new domestic Australian and Japanese competitors? I sure as hell hope so.
