The dips are a result of the ECU learning to pull timing. It is part of the learned map, it didn't happen on the dyno.

^^^^^^ :huh: so who all went wheres the rest of the #'s?

Matt - what did your car put down :?: Did the rice pipe help? Wanted to know what you did with those wheels on it? Give me the info.......... :lol:

Yesh, the wheels scrubbed a bunch of power, as I thought they would. So with new pipe and Wheels, I put down 221 HP, still not too shabby. it's hard to tell what reality is with my higher elevation ecu only running at altitude for a brief time.
|
I was woundering more so to put a finger on why may #'s where lower when we went back to back. Wheels must play a big difference in power!

I ran with 18 the first time and got a 228/226/and a224
I never posted my results the first time! |
Heavy wheels affect accelreation but not power. Matt's power loss comes more from his tires being too tall than from the extra weight.

We are running the same size differnt brand I have a yok avs 100 235/40

IIRC: heavier parts = more drivetrain loss = less torque applied to the dyno = lower tq and hp numbers (since dyno hp is calculated from the torque)... what am I missing? |

I still have a hard time buying the rotors causing that much of a difference. The calipers and pads wouldn't affect the rotating mass at all. Yet another testimonial that dyno results all need to be taken with a large pile of salt. |

Doesn't the mustang dyno measure based upon how quickly it can accelerate the rollers? (I suppose that would be inertia based - duh). How does a load based dyno work. Does it measure how much it can resist the wheels? If so, wouldn't a heavier wheel, brake rotor affect this also? I have heard the same issues quoted with HKS's dyno. |

Where do you guys get your AWD's dyno'd?
