This eliminates all the nasty variables like strap down tension, tire pressure, alignment, etc. It allows us to truly see what the engine is doing instead of worrying about the other issues. For tuning purposes, it is, IMO, the best system on the market.
Generally, this dyno reads 5-10 hp higher than a traditional roller dyno like the Dynojet thanks to eliminating the tire issues. However, you cannot directly compare results between the two types of dynos. In fact, you should never compare results between two different types of dynos. Any dyno can be used to compare before and after results on a car, just make sure that you follow proper procedure and control the test variables - which depend on the sort of dyno you're using. A chassis dyno is not a good tool for measuring absolute power, but for measuring power differentials.
That's why I suggested you guys read the dyno section at the Hondata site. :-)

Wholly, don't know if this matters at this point but I did all my dyno runs on an inertial dynojet setup and the same place. You claim 5-10 whp more in comparison. I should be well ahead of the curve then. ha.:eek: You made my day Shawn.
