Power+weight+time.
gtpete:
Hello everybody. Just to help me along with my build and give me something to look forward to. Can I make a pole of your FED weight and what 1/4 times you run. Thanks in advance Pete.
dreracecar:
Weight divided by ET3 (cubed) X 197.14 = HP
1650# / 343 (7x7x7) = 4.81
4.81 X 197.14 = 948 HP
Rough terms is that is how much HP is needed to move that weight 1320' in that amount of time
gtpete:
I'm ok with the maths its just some real world numbers i'm after.
dreracecar:
My car weighs with driver 1650# and I run in 7.0Pro index class and usually hit the number. I dont have the time or money for dyno time to get HP figures, And that about how "real world" I get
retroboy:
Not real world but the Wallace racing calculators have a simple calculator on their web page
