ET with and without wheelie.

[KRatcliff]

It is simple physics with a massive amount of variables. You have a stationary object that is being measured by time over a distance. Whether or not a wheelie adds or reduces that time isn't a cookie cutter answer.

There are so many variables which impact each and every car. Some examples are power band, gear ratios, aerodynamics, traction, suspension, and parasitic loss.

Take the last three and apply it to whether or not a wheelie will impact the 60' and eventual ET. A wheelie may aid in traction by the transfer of weight, but it also may be wasted motion to some degree or it may alter the suspension/pinion angle enough to create more parasitic HP loss. Too tight of a front end may keep the engine from reaching the ideal power curve thus negatively impacting the 60'/ET.

Experimenting with different settings and setups will get you closer to the optimum performance and it what makes all of this challenging. It is frustrating a lot, but also gratifying when you see the improvements. It can be binary to some degree if you make limited changes with each pass.

Edited to add: Wheelies are flipping fun.

How tight the frontend is can be very important to a lower-powered car that may just barely lift the front wheels or not lift them at all. Too tight and it can cause the car to struggle through low gear.

Yes, they are!

Not about the narcissist comment. I was married to one for 50 years. I know the signs. Why would you think I'm talking about you anyway? Have you been called one before? Seem a little defensive?

you're balless too

Let look at a car that has a frontal area of 25 sq ft and runs 12.0 @ 113.14, 60 Foot ET = 1.7851 - MPH = 40.09

If the wheel stand cause the frontal area to increase to 50 sq ft (doubles), but you can't use any added wheel thrust then 60 Foot ET = 1.7872 - MPH = 39.98 MPH

Stan


PS Let add that the 1.7851 60 foot number is with 12 inches of rollout. With 6 inches of rollout the 60 foot time would be 1.8532

Also a trait. Insults if disagreed with. Hmmm.

Without a data recorder to back that statement up, it's just opinion.

Oh and my data recorder proves that opinion to be incorrect.

I have a data recorder and the results conflict your OPINION.
