Kilowatt at the wheels

[AE86R]

From old dc, posted by jonny rochester

The loss is generally about 30%. So...

If your motor has 80kw (107hp), you would get 56kw (75hp) at the wheels.
If your motor has 90kw (120hp), you would get 63kw (84hp) at the wheels.
If your motor has 100kw (134hp), you would get 70kw (94hp) at the wheels.
If your motor has 110kw (147hp), you would get 77kw (103hp) at the wheels.
If your motor has 120kw (161hp), you would get 84kw (113hp) at the wheels.
If your motor has 130kw (174hp), you would get 91kw (122hp) at the wheels.
If your motor has 140kw (188hp), you would get 98kw (131hp) at the wheels.
If your motor has 150kw (201hp), you would get 105kw (141hp) at the wheels.
If your motor has 160kw (214hp), you would get 112kw (150hp) at the wheels.
If your motor has 170kw (228hp), you would get 119kw (160hp) at the wheels.
If your motor has 180kw (241hp), you would get 126kw (169hp) at the wheels.
If your motor has 190kw (255hp), you would get 133kw (178hp) at the wheels.
If your motor has 200kw (268hp), you would get 140kw (188hp) at the wheels.
If your motor has 210kw (282hp), you would get 147kw (197hp) at the wheels.

This chart only applys if the loss is 30%, and that we can never be sure off. Also, the 30% loss is not a constant with all amounts of power. It is used here as a rule of thumb.

I thought it was closer to 25%?

[AE86R]

i have also read around 30% or to be exact 29.2%

[Wally]

So a stock bigport should have 64rwkw according to that?

Johnny Rochester knows everthing. Also, I belive one killowatt is approx 1.41 horsepower. That might be of some use in this thread.

Doubt I'll get my 100rwkw then from my engine

[AE86R]

1 kw = 1.34102 hp

1 hp = 0.7457 kw

[Wally]

1 kilowatt = 1.3410220924 horsepower
