First Dynoed M3 in Taiwan

[Eugene-TAIWAN]

OK, here goes nothing,

First of all I don't know which gear to pull the car in so I made 2 pulls one in 4th and the other in 5th.

And honestly I don't even know how to read the dyno graphs. So if anyone can help does the number show this is my WHP??? or Engine HP??

Your car made 393hp, and 305ft/lbs torque. Your entry is now visible in the DynoDB: bmw.pencilgeek.org/DynoDB.html.

I'll need to review this later because it seems like you let the Dynapack calculate your gear ratio. If that's the case, then I'll need to adjust your results slightly.

Can you send me the Dynapack dyno files?

Hi PG,

do you mean my car only had 393HP NOT WHP correct??? I just read the your instructions they place only had 2 fans about 30 inches in diameter. but I will go back again to see if I get a better fun with your instuctions.

You can ask the Dynapack operator for the files -- put them on a USB stick and send them to me.

Yes, I will get a hold of him today and see if you could email the results to me. I think lacking of a strong fan also has something to do with it. like you said it can result to a loss of 30-50hp.
