Racepak for stick cars

[MOTORSPORTS Innovations]

I get more and more calls on Racepak for stick cars. The questions are usually:

1. How hard is it to use the software to see slip. And this breaks down into A: do I have to be a computer wiz and B: can it really show what is going on in the first second?

2. How much does it cost?

To answer the first question, here is a graph from a Pro Stock car where I have zoomed in on the first 2 seconds of the run. (it's the only one handy - anybody want to send me some Stock/ SS stuff I'd like to see em) with the 4 steps highlighted.



So the steps are:
1. Click mouse cursor on the time into the run
2. Use arrow keys to get the time exactly where you want it (in this case .102)
3. Look at slip percentage (16% for this car)
4. look at lock-up curve (yea, I know there are two #3's)

The Red line is engine RPM, Blue is the drive shaft, Green is the input shaft


Make adjustments to car and repeat until you run quicker than the current record in your class

How much does it cost - $1119 and that get's you a Racepak Sportsman logger, input shaft sensor kit and a 9' cable, software, cables and laptop accessories. Besides reading the input shaft you get engine RPM, shaft RPM, accell & lateral G meters, and volts. Adding O2, temperatures etc is easy.

Let me know of any questions.
