Fast fd !

[JhnRX7]

Did some testing today.



Here are two 90-140 kph runs. Run #2 was slightly uphill (about 2m) and run #3 was slightly downhill (about 2.5m). I am guessing this puts me somewhere in the area of 3.5 seconds. I can send the .dbn file if you want it.

Car is a 94 FD with stock twins setup non sequential. Medium-ish ported engine, 3" exhaust, intercooler, intake, etc. Both runs were performed at 12 psi on 93 octane (no water injection). Last time it was corner balanced it came to 1338kg with me in the car.

Log of one of the runs:



I started working on the power calculation following the formulas you have posted on your website. I went out and used the performance box to take some rolling data on level ground. I was able to calculate drag coefficient and rolling resistance. My car has the Mazdaspeed GTC bumper so I would expect a larger drag figure, however I got double the stock value... Rolling resistance was in line with your figures.

I'm stuck on the power calculation... I dont understand the variable "Vspeed = vertical velocity". I see my performance box has a channel for it, but it does not record any data. Can this be calculated?

Just eliminate the vertical velocity component, only a VB3i will measure this properly or be of use.

Refer your performance to many FD3S in similar spec here > http://www.riceracing.com.au/vbox-ii...ing-tuning.htm
