An so the saga which is day's of our life continues...
Chris. I think when Wreckhead run he had a leak from the NAWS system, then fixed it and Alex tried his hand at it..
I know it still will not give you an exact HP reading, there is some truth in the drag racing method. Although I do believe that it takes more than just 1 run down the 1/4 mile to get a good idea. On a dyno you have more than 1 run and then the output changes at a different dyno.
At the end of the day who care as long as I leave the dyno with more HP than when I arrived.
