question about hp

[bigjohnson4.6gt]

is there a relationship between rwhp and hp at the crank, like if say you have 240hp at the crank could you find out roughly how much rwhp you have or vice versa? just curious

i think it's 15% drive train loss for manuals and 18% for autos.. or so is the general ideas..

yes..... if you have 240flhp with a stick....figure a 15% power loss from parasitic drag.....which roughly translates to 204whp. Stock autos will have a higher percentage of loss.

so about 18% loss for autos? thanks guys
