im sure someone has posted a link or a calculator for horspower on here but i havent seen it.

it calculated how much horse power you make based of your 1/4 mile trap speed (trap speed = speed at end of 1/4 mile) and your total vehicle weight (remember the list posted on here is dry weight so add your weight plus liquid weight to the dry vehicle weight)

or take your car to a dyno

 

i will after the turbo install but this gives you a rough estimate of what its got. not exact but close.

 

it's only accurate if you shifted at the perfect spot every time when you were doing that 1/4 mile run.

 

i understand that, thats why i said estimate not exact

 

That could be very useful, Especially if you live a few hours away from a dyno.
