Eight horsepower in six years? Are you sure you believe that? Gains are certainly harder and harder to come by, but consider this: six years ago in Reading, Jim Yates was on the pole with a 6.82 at 200.80. Martino was number-16 with a 6.85 at 200.26. Speeds less than 200 (199, etc.) were still commonplace. By way of comparison, this past weekend, Anderson was number-one qualifier with a 6.61 at 208.84, while Rickie Jones was number-16 with a 6.679 at 206.29. Performances are continuing to improve. We're talking about a difference of two tenths and 8 mph.i know that the guys running the highest mph are making <20 h.p. or so more than the other fellas. i talked to one guy that said he was in the dyno department for one of the pro stock teams. been working there for 6 years and has found 8 more h.p. through tuning. talk about a small margin of success.
First off, stop believing that, spinning the tires does not result in bigger speed. If I spin the tires, then come back and make a nice run, it is quicker and faster. So please, stop believing that, BGhard to say tire spin can give you more mph..
b.g would probley be the best in the know though
