Check it out, its a device added to the driveshaft at the yoke that measures your HP precisely. Way too expensive for my tastes but pretty cool for a guy who does a lot of test and tuning, to know if the mods really increased his power output

HOW IT WORKS
AEM uses a set of laboratory-grade strain gauges inside of a supplied slip yoke to measure Torque at the driveshaft. Essentially, the Dyno-Shaft slip yoke becomes the sensor for measuring driveshaft Torque. This is combined with a driveshaft speed sensor to precisely measure the rotational speed of the yoke to determine RPM. The combination of real Torque and RPM readings allows the Dyno-Shaft to output Torque and Horsepower numbers as accurately as any dynamometer but in a more useful setting, and eliminates all of the inaccuracies associated with accelerometer based systems.

Very cool.

I think the price is pretty reasonable to be honest...

[Stangman Jonathan]

that is pretty damn cool, if it does what it says then it just may worth it to some.

[Diablo750]

Yeah that's pretty cool

Very cool. Price is pretty steep to me, not something that would ever be worth it for me. But I'm sure there are tons of people that find it worth it.

If you are someone that is constantly tweaking your car and going to the dyno, this is definately worth the price. If you just like to cruise around or make a change once in a while, the price is a bit much... Still think it's cool though

[hwmightyman]

Awesome if it works a well as it claims but way to pricey for us average Stang owers

Also, I didn't see anything mention if it was NHRA legal? I wonder if you'd make it through tech with something like that?
