What I am interested on how much am I getting slowed down from my GT Wing

So attached is a chart provided by APR for the GTC-200

I have set my wing angel (AOA) to 0 degrees

I want to know how much does it slow you down in a quatermile

caused by the drag

but what I don't get is that I don't think it should matter that much since the data

suggested that drag is very small

but LETS GO

That's an interesting question. Most people are trapping anywhere from 92 - 99 mph depending on various factors in the 1/4 with no wing, but I'm not sure how you'd factor the downforce and drag values into the situation.

Ooooh. Excellent question. To come up with an exact answer would require a lot more information, i.e., weight of car and rate of acceleration to be able to make an exact calculation. Since the CD is 0 at rest and increases as the car speeds up that means there isn't a constant to work with and I'm not smart enough in the math department to do those calculations. My best guess for 0 AOA is about a tenth of second penalty in the quarter mile.
