Zero to 60

Has anyone been able to hit 0-60 in 2.9 seconds as advertised? Best I can do is 3.2 seconds

I can do 2.6 - 2.8 all day long, but I live in Florida at sea level. The elevation you are at has a lot to do with the times you are able to achieve. I was just at the Spring Mountain class this last weekend and my best time was 3.4. Elevation as well as temperature play a big role with your times.

Agreed I hit 2.6 here in Florida regularly have even gotten a 2.5 twice. Higher elevations much harder to attain same.

I haven’t raced at elevation, but have run in the summer which can be an equivalent DA swing of a mile high from winter and that’s approximately a 1/2 second difference in the 1/4. The 0-330’ time varies less than half that, I don’t see how there’s more than a .2-.3 second variance in 0-60mph which is mostly traction and mechanical gearing(which isn’t affected by altitude/DA). Driver weight, passenger weight and fuel load I believe could have just as much affect on the 0-60mph as the DA honestly.

Right or about 15hp in the case of the C8, which is around a .1 in the 1/4 mile for a low 11 second car. How much hp is needed to gain or loose a tenth in a short 0-60mph burst that only takes 3 seconds?

It took several TRIES TO GET MINE TO WORK. You need to be at a dead stop to start the timer

Read the owners manual carefully on how to set parameters
