As I said above there is too many other factors which will result in different outcomes. Also the FD you spoke of ran those times at around 2700 lbs, because listing the car with out the driver weight is useless. The car didn't drive it self down the track, an average person I would think to be 140-200 lbs. Another thing to think about which may not make much of a difference, but this is in a 240SX not FD. I just think to prove the the claims another dyno run would be the best route to take.

This thread is turning to shit quick.

If you doubt speeds as a measure of power then you have no idea of physics. You can learn some by looking at my page, use proper gear and you will see direct correlation with "terminal speed" and "power" or lack of power in some peoples cases

I for one accept dynapack (and you rear hub power result), they are one of the best dynos period to use in the common battler spec domestic person "off the street general public" alternatives. if you run it at 1.00 TCF then what it gives you is what you have. In my experience if you want to guess your engine power you ONLY use a TCF of around 8% *little more* when you apply this to proper physics *again see my web page* you will see that if you are honest (weight measure) and (engine power estimate) then YOU WILL EQUAL the theoretical "mph" terminal speed target at std temp and pressure conditions.

But hey I only do this everyday and teach it for a living as well it helps to have the best measuring gear in the world and an education to make the most use of it when you tie it all in together you see that lots of stuff makes perfect sense in dyno land and in reality land
