Rule of thumb is one tenth per 100 lbs. up to 3000 or so. The it goes up.
It has proven very accurate in my experiance.

.1 et and 3 mph slower, according to a online et calculator. Assuming apprx 3,000 pounds track weight. 3,000 pounds was 9.15 @ 150 mph, 3,100 pounds was 9.25 @ 147. FWIW,SteveW

Correct again Steve. 
Add 100 HP and lose a second in ET providing you can put the power to the ground.------------------

I aggree.But the 100# = +- .010 is pretty damn close. A lot closer than chassis dyno figures are anyway.
But that's another thread. ------------------
