just because people have been using it doesn't make it CORRECT num nuts. Come on people used to beleive smoking was not harmful until science proved it could be. In fact it is even more proof that its flawed as older cars 60's & 70's tend to loose more through the drive train than the modern counter parts. So go figure The only reason people don't like hearing it, is beacause people like you just get upset when they find out their car isn't as powerful as they hoped. However hoping it produces more power and using inaccurate methods of calculating it won't make it any faster at the track!
