Not Ranked
i have been to 3 chassis dyno shops. two of em said they typically use a percent loss figure of 17-21% for sticks when doing pulls in the 1:1 ratio ( 4th in a 4spd and 4th in a 5 spd) . the 3rd says he subscribes to a total hp loss, figuring 75-100 hp for side pipes etc regardless of the engine size or crank hp ratings . all admitted that most of their customers who have had engine dyno tests done are disappointed at a lower rwhp figure than they anticipated, and also said that most overstate their engine hp whether with fact or without. naw, who would do that ? hey, did i ever tell you about my 9 cubic inch 200 hp briggs and stratton ? LOL. B
