TECH: Car Math e/t, weight, 1/4, 1/8

http://www.rdrop.com/users/larry/download/formulas.pdf

Sites that do the math for you:
http://www.rpmoutlet.com/dyno.htm
http://robrobinette.com/et.htm
http://www.prestage.com/Car+Math/ET...t+/default.aspx

I have used these formulas & sites before to see how acurate they really are. They have been extremely close if not dead on.

There are factors i.e. drivers skill & ground level, traction etc.

Server error application on the last one

3rd one has annoying popups.....
I still didn't see where 100lbs = +.10 ET

Good read however.

Chronic it actually depends on what formulas you use etc.
But on average its -100 lbs = +.10 or .20 give or take.

Loosing 100 lbs is atleast .10 off your e/t that was what I was trying to inform you of.

I was baisically trying to get a point across, I didnt know rounding calculations were going to make you so upset.

Here you go chronic:
http://www.geocities.com/tek_civic/weight.html

He calculated lossing 215 lbs out of your vehicle will reduce your et by .25

That is about 100 lbs for .10

w00p

I would have to agree 100lbs taken out easily will get you a tenth.

Chronic, there are too many variables to get exact numbers.
You can average out results hence having a range of decently acurate results.

Yay to Ron for not being a block head

Using a generic et calc and hp calc that reduction should give you about 9 WHP and .25 off your ET. Note that these calcs are inaccurate but give a pretty good estimate. Not bad since its all free, and can be put back

Since when does making your car lighter... give you wheel hp? THAT'S a new one.

qitstrn: I agree, as per the calculators that I use shows about .225 or something for 100lbs.

He simply stated it as being a fact that 100lbs = .10 as if it would always be the case.

Since I feel that is wrong. I challenged it. Saying prove it.
It's aparent however he stated that out of blindness because he changed the answer.
