Go to Stan Weiss web site, pick the calculator you need(he has free ones), and don't forget to add the drivers weight, because the car was not on remote control. Over the years his seem to be the most accurate I have seen. Ive seen some that are way off. Experience says 114 is about what you...
You will never get an accurate et from your calculations. The calculator uses data from lots of good runs to get its estimation. Friction as it relates to traction is hard to quantify. Yet, mph, distance and weight is a very definable value. Et is a whole nother story. But I applaud the attempt...
You haven't shown me anything, you just quoted magazine data, tell my mathematically how a camaro can defy physics, and start with the laws of thermodynamics.
Let me know when you are more accurate than the 2 input calculator. That's why we race cars. I been using that website for many years, and its always been spot on.
Because force over distance tells me how much power is needed. And if you are going to deviate from that, it can only be slower, not faster, unless you have less friction losses than everyone else or you have extra force applied, period. How about you bring YOUR car to the track and tell us what...
Can you find a better one, probably not. People been using formulas just like that for a long time. Try answering a question with something of value other than comedy. F=ma is pretty simple. Try applying it and tell my why the camaro can defy it.
The only things that can throw off the formula are large temperature changes, windy conditions, and low or high frictional losses in the driveline. There is always a mph or 2 diffrence between autos and manuals due to friction losses, in the past being higher in autos. The geartrain of an auto...
Horsepower, weight, MPH. Trans doesn't matter. Physics don't discriminate. Slight differences in power-train losses and wind resistance, but still very close. That weigh, moving at that speed, in that distance, end of the story.
What you have to realize is, cars in this power range, if you put slicks on them, will pickup (drop) .3 to .7 et, but the mph won't change much at all, if any. Sometimes they lose a little MPH. You just don't see many stock cars running drag tires, the tune almost always comes first. MPH relates...
If you want to do it yourself, here is the link.

Try the 122 on the Cadillac to see a real hot ringer, easy to do with a turbo.
MPH don't lie, and the formula is the same between all cars. This has worked since isky made the dream wheel for figuring out these things. Its not perfect, but its damn close. Even wheel-spin wont affect mph much unless its ridiculous.
