My car is nothing special, just an FD with non-sequential twins running about 12psi.

90kmh to 140kmh test standard in 3rd gear*** It would be nice to compare your car to these similar ones
I also have quite a few friends with single turbo cars locally so I can try and get it in their cars for more data. |
100% right.
There are two tests that are great to do:
90kmh to 140kmh (3rd gear power band test (Rice Racing standard) you will see the under my VBOX page)
*** This is a VERY POPULAR test as its fast, very quick, easy to do, and lets you test the power band from ~4500rpm to ~8000rpm (depending on level of wheel slip!)*** http://www.riceracing.com.au/vbox-ii...ing-tuning.htm
100kmh to 200kmh (3rd gear to 4th gear to 5th etc, acceleration test)
Note: in the acceleration test, say if you have a poor power band you can start off in 2nd gear, its totally up to you, whatever makes your car faster, you can change up to 5th if your car wont rev out, its up to you!
To do either one you find a flat bit of road, start in gear a fair way under the set speed (say 70kmh), mash the gas, and run it out over the end speed (say 220kmh). The data is extracted post processing using the VBOX Tools software, and a report is generated (just like show in my VBOX testing page on my site.
If you boys go the extra level of getting an accurate weight measure of you cars (with you in it as when you run the car) I will then apply my own developed formula and create another maths channel on your data log you send me, this will be a power channel and it will show you the power at the rear wheels during your runs *simple* It is a great way to see what power you have, and make on the road during the test. I will do this for everyone who sends me a file. The results will be collated in the first page/post of this thread and we can have a resource for people to look over and easily compare & ANYONE can spend a little amount of money and go buy a Performance box and run their own tests and send me the files and get amongst the action and fun that is testing your car and finding out exactly how powerful and FAST it really is
