does anyone have one of these or the bel version?if so,do they work and are they worth the money?[sm=badidea.gif][sm=goodidea.gif]

 

I have an older one I bought in '99. It seems fine to me, and will give a pretty accurate idea of the performance of your car. I paid $99.00 for mine.

 

A buddy of mine has one and had it in his procharged camaro during a quarter mile pass a few years ago at Island dragway, NJ. The quarter mile time was off by only two tenths from the actual time. Horsepower numbers were way off because of wheel spin.

 

my husband has one also and he agrees they are pretty close

 

thanks,just bought ss model.now need to set it up and try it.
