I used my Vericom VC200 (vintage late 1980s) to do some performance testing on my two smarts today. One is bone stock with 3400 miles. The other has nearly 12K miles with K&N air filter, Forge Silicone Air Hose, DTH single out exhaust plus my own home made torque strap.
Conclusions: My view is smartUSA published 0-60 at 12.8 seconds is probably a good average and was not achieved with all out maneuvers for the best times. Maybe some of the Pures with no options could do closer to a 12.0 when pushed hard and the right circumstances and some of the heavier optioned cars running at the published 12.8. This is just my conclusion that just about every smart can run the 12.8 second 0-60 if it is running good.
The VC-200 accelerometer was tested at the track by many of us years ago. It does do a calibration before each run to check the angle of the car etc. Anyway my times with the VC200 seem quicker than some of the other drivers. I can tell you that I did watch the speedometer against the VC200 and the VC200 got to 60 when the speedometer was at 56. I am wondering if the speedometer is just slow in showing speed when accelerating (has some kind of lag or just mechanically slower). With that said, my modified car ran the best 0-60's (12.0) and beat my stock car by .5 seconds. In 1/8 mile they were closer. The VC200 only does one test at a time (i.e. either distance or speed) so I am adding my best times for 0-60 and my best times for 1/8 mile to my file.
The VC200 and it's predecessor are no longer made and I can't even find any on ebay. Vericom makes some heavy duty instruments which they call on board vehicle dynamometers now running for $2.5K to $4K. G-tech seems to have a following and their stuff can be easily found.
I now have my baselines and even have recordings of my Scangauage II for the runs to show shifting and HP. As I mod I'll be able to see any improvements.
KUDOs to LittoDevil, Barney O and jr4488 for finding ways to improve the 0-60 times.
