This is a bit of a long shot, but....

Does anyone know what the frontal area of an M series car is?


I'm aware that I can get a rough'ish value by taking a photo, but after reading a bit more about it, it seems that there are lots of things that can distort the value and make it all wrong.
So, I've seen people modelling chassis' on here, biggrin, so has anyone measured the frontal area?

I've read 21-22S.F. for Datsun Z and 17S.F. for Sunbeam tiger. I'd guess the M to be 20 or less, probably 18-19. I have a top speed/power req calculator spreadsheet laying around in Excel. I used 18.3 on that.

What are you using it for?

I'd forgotten about this.

I'm making a car simulator with realistic physics for my final year project.

I was planning on using our 1600M as the test car as I can get all the measurements from it.

Thanks for the info Slow M, nearly got my full data set now, just need a coefficient of friction for the tyre, which I've got a rough value for (no idea how realistic it'll be).

There's a way of calculating rolling resistance from using coast-down information. I'm sure you can find the details online. Shoot me your email address on PM and I'll blast you the Excel calculator. Some of it may help.

Put some Pic's of the Griff on the club site, in the Grif bit!

This is Thomas' post though?

Yup, my account, biggrin

Forums are one of the best places to find obscure info IMO.
