Wally just mentioned the key...TLC and quality workmanship.I started the 1200 Challenge in 2009 and the turbocharged engines were all pretty similar as the rules dictated a stock bottom end and the 77mm bore.Armin Klein held the crown since then with a 130hp turbo 1200.A more aggressive cam and better tuning brought Wally these results.Personally I believe that Wally´s ability to tune and dial in an engine is gets him these great results,just like with his 2.2 T4.Especially if you compare to how the other competitors´engines run and how they act under a load.There´s no cooincedence or luck involved
