Kind of new from Racepak are 8 magnet shaft collars.
With 4 times the resolution, it helps with the mystery area immediately after the TB release and (possibly) before the stop activates. Combined with the 12 volt event channel in the Racepak you will be really able to see this time span. I get may calls about this from .90 racers and now there is a good answer.
For those of you who don't yet have a data logger, getting good logs on that critical time has been problematic. I ran 10.90 and 8.90 years ago so I have some feel for how important that first .5 is.
They are only $80 and will work with Edelbrock, Innovate DL-32 and probably any logger out there. Unfortunately only the 2.187 and 1.875 sizes are available. I think a spacer could be easily made the adapt the 2.187 size (Mark Williams large pinion) to the Strange and Moser sizes. I have a Moser on my car and will be making and adapter for it.
