I thought I survived on not much sleep :-)

OK. Now realise where your reference is. I see that it is the dynamic vs =
static load states that are the issue in my head. My se7en tends to have =
3 modes

1. Accelerating as hard as I can
2. Braking as hard as I can
3. stuck behind other traffic

The aim being to minimise 3. As such for me WOT is always an =
acceleration mode vs bonneville case which is a terminal velocity mode.=20

it is the 'biggest hill' so to speak. A drag race car seldom reaches =
terminal
velocity a Bonneville car does as does a car on any long race track. The =

open wheels. Goes 211 N/A out the 5 mile marker in a 1700 lb car with a =

Cosworth YB. Now if you took that to a drag strip in might go what an =
11.0 at
120 maybe? maybe slower.
