Are the sensors specific to the brand of recorder? I do not yet have one but like RPM Performance out of OKC. Many friends have their system and I have heard no complains.
Racecar spelled backwards is racecaR

shoe polish... SOLD  :)

just a 0-5v sensor.  does not have to be data logger manuf. specific.  can adjust values for min/max in software.    im gonna do some more digging, ill look and see what RPM Performance uses and maybe i can use that too if just a 0-5v sensor.   when doing search's for load sensors Racepak always comes up.  i can find the load sensors themselves and fab a housing etc for it.

Im questioning the need for it and what you hope to acheive by having one?

 Now I have installed hight sensors on the back of fuel cars that measure tire squat- getting up on the tire-and when they go up in smoke, all base on time after the hit to allow an understanding of clutch settings and so forth. That little do-hickky (about the size of a zippo lighter) is around $700

the ride height sensors are spendy.   i was looking at them for my old car.   i understand this type of racing has been around for eons and people still race till this day with minimal 'accessories' and are very competitive and win races.     i can see with a clutch car it would be important on setting up the clutch and dealing with the hit.   honestly, its just something i would like to do.

When we were running the Comp car the most important things to monitor were engine rpm and drive shaft rpm . We would also monitor fuel pressure , oil pressure egt and pan vac . As far as the wheelie bar goes we used good old american playground chalk ! Real easy to put on and easy to see on the track !

Not sure what wheelie bar sensor will tell you that front wheel sensor doesn't.If wheels are in air you know.I think chalk or shoe polish will tell you what wheelie bar is doing,provided you have decent helper on the line with you.

Wheel chalk along with a helper at the rear of the car is what I do. I have one helper with an I phone recording the run in slow motion helps as well.  I see some of the pro teams use a camera on the track to capture movement at the tire & wheelie bar.

The problem with all this electronic available information is that most dont know how to read it or what to do with it that all it becomes is just pretty squigly lines on the computer screen to impress people. Just look at the pros--- they have hundreds of thousands of dollars invested and they still miss.

  Learn how to judge and tune without it, then you will not have to worry about the system crashing

Don't always agree with Bruce.Here he is dead on.I use the old school tunning and dbl check the computer.Best computer in the world has hard time telling you what is happening in combustion chamber like a spark plug.Then you have to know how to read them both.

The best tool you have is little piece of paper you get after the run.Any tool that helps figure out why it is the way it is,is a good thing IMO.If you feel a sensor on wheelie bar will help you then by all means use it.
