Default Weight vs ET/mph

What do you think the increase would be in et/mph if you take out 200lbs? I just redone my car from top to bottom and took out about 225lbs. Trying to get a ball park on what it should pick up. Best at 3450 was 4.90 at 143 on a .044 single stage.

a friend of mine has a turbo car. when he had to add 100lbs to his car to run in OKTT5. he lost a tenth. so i would say 100lbs per tenth.

That is all flat weight. Might save a little rotating weight also. Might be putting a billet bolt together in the car

when ever we have added weight the car always went faster, but this was usually to fix a problem IE the front end coming up.

I don't know but we checked it on two sets of scales and it showed the same thing. We always thought it was crazy also.

That's what I was thinking a .10 and few mph and then pull it up some and get a little more out of it. I would be happy with those numbers

Losing 90 lbs is worth .1 for Pro Mod cars running 3.8 - 4.0 , with your power level I would think losing 225 lb you should see .14 - .16
