zrayr -- dyno numbers can be sneaky. It might sound like Rod's 605HP is a lot more than my 450HP
... but it might be closer than you think. My 450HP is with the pipes on, air cleaner on, and water pump churning. Pull all that stuff off and you can get a dyno well in to the 500's. Now if Rod's 605HP number is with open pipes, and maybe a few "adjustments' factored in on the dyno, he could be well down in to the low 500's with an "apples to apples" dyno run like mine. You can play a lot of games with dyno numbers... a
lot of games.
