Err... how does that relate to this discussion?

Ahgh NO
as I said before speed and the power needed to achieve it do not relate linearly, but to the 3rd power. 35% less drag will have the same effect as (100/65 - 1 =) 54% more power, but that will give you just a (1.54^(1/3) - 1 =) 15% higher speed.
As the L3's gearing is long it might be even slightly more than that, but even so you should be happy with anything close to 190 km/h.
If you want to reach 266 km/h you will have to reduce the drag to 24% of the original L3, not 65%.

Glad you do. Looking forward to that, as you know I'm very interested in the project.
Don't want to put you down... but 266 km/h cannot be achieved this way, because the relation between speed and power is not what you thought it was.
I like to drive fast, but the fuel consumption rises in tandem with the power needed so I seldom do high speeds anymore.
I will do so though next July as I will then take the Insight to Germany's Autobahns. The 90 hp and .28 Cw should allow it to reach 185 km/h. I'd love to find that out.
