Okay, they took their 408hp '70 Duster the weighed 3012# and cut it down to 2424# for a total loss of 588# !!! Note that all these figures are less driver. It ran 7.627 @ 89.38 before and 7.235 @ 93.95 after. They estimated that the quarter mile times would have been 11.93 down to a 11.35 for a 5.8 tenths improvement. Another interesting factor was that this was a cost-no-object article and that over $10K was spent in the process. Thats a bunch of dough, but hey, at least it was done for the better interest of Mopar community! (and it wasn't a Chevy!) FYI, this is taken out of the Oct. '03 issue of Hot Rod.

#'s lost = pounds removed
total = total vehicle weight in pounds
F/R# = Front and Rear weight in pounds
F/R% = Front and Rear weight in percentage
W/P = Weight-to-Power ratio(not the commonly used power-to-weight ratio, since the power is a constant)
C/PR = Cost per Pound Removed (they also said that CPR is what you might need when you see the price of some of this stuff !)
cost = cost of parts/modification in 2003 dollars

The attachment shows the chart that I put together.

If you would like to see the original article, here is a link: http://www.hotrod.com/howto/113_0310_loseii/index.html The article gives details on all the parts that I listed on the chart. It was an interesting approach at losing over half a second off your ET without ever turning a screw under the hood. Cost effective? Not in my opinion, but I still give them credit for showing some ways to do it and the differences it made. And also, unlike power adders that probably add strain to the engine & drive train trying to achieve that ET reduction, the lighter weight no doubt reduced the strain/stress on the engine & drive train. I hope this helps.
