Anyone ever heard of this: Home Dyno
 
I was looking at this dune buggy site and came across this thing called the Home Dyno. Does this work? It sounds better than the G-Force thing.

According to my precise calculations, it's gay.


the Home Dyno records the spark pulses via a WAV file that you "record" into your PC
Simply Genious! Why didnt I think of that? You see, if you have your spark pulses in a WAV configuration, you can play them back using media player, giving you exact hp/tq numbers. Awesome!

It'll work, it just takes a large amount of setup time. You have to know everyting about your car to get the math just right.

Weight, transmission gear ratios, tire diameters, etc. are critical to making the thing work. Basically, one revolution of the engine, will rotate the tire a particluar amont, in a particular gear. Tire diameter, when calculated with the amount of rotation, gives distance covered. The pickup on the plug wire counts revolutions against time. From there it is a matter of calculating the number of revolutions (distance covered) against the elapsed time.

If you know all of that, then the math will tell you the rest. Road Dyno provides a way to collect engine revolutions over time, and a way to enter all the info needed to extrapolate the rest of the performanc info through calculation.

We were looking at this solution as a way to baseline our project cars. We may still buy one to try it out. I the meantime we purchased a G-Tech unit, which we are not too pleased with. We thought it would be simpler to use, and it is. But the information is limited. The G-Tech unit shows only net HP, not actual. This means that wind resistance, driveline loss, and other factors are not compensated for.

This means that our 106Hp CRX, is rated at 82Hp by the G-Tech unit. The nice part is that there is no analysis to be done, unless I want to use the 1/4 ET given by the unit, to convert back to actual Hp.

I'll stop now...
