    Hi,

    no, I'm definately not calling.

    Causing confusion - well, I am stating here that no confusion should be caused so that closes that!

    It's clear there is no messing around here.

    Good result!

    67whp? My company? Please direct me to any graphs as I am not aware of anything that shows a before/after of this much gain unless we are talking S62.

    Our gains with exhaust and tune are around 40-50hp under strict conditions. Sometimes less.

    Thanks - out of curiousity have you seen a difference in 6spd to M-DCT cars and the way they dyno at your facility. This car is M-DCT. If the drivetrain losses are correct vs. a true 6spd theres no reason a 6spd M3 shouldn't do 415-420 on a dynapack in this trim. Hopefully well find out some day.

    Same power readings at the wheels on both types of transmission.

    Where did you see 67hp from us?

    That shouldn't be.

    That's what we get Joseph. Time and time again.

    You dyno the manual in 3rd and DCT in 4th. The ratio's are shorter on DCT. Due to this the wheel speed is much lower and this skews the results downwards if tested in 3rd.

    The only way to actually see if the drivetrain losses are higher or lower is to fit a different differential (longer) on the DCT so 3rd gear would match the road speed of a 6MT in 3rd.

    Suggesting the drivetrain losses are different from a dyno when you have different gearing is not plausible especially when your talking about a machine which skews the figures between gears.

    3rd vs 4th on 6MT vs DCT respectively, the road speeds are not that different and make for a much more equal test.

    I believe you, just doesn't agree with what dyno operators in the US have told me.

    It may be due to the cars being dyno'd in different gears by you but the DCT has slightly higher losses.

    That DCT's dyno less. I also did a writeup on DCT drivetrain losses compared to manual: http://www.bimmerboost.com/showthrea...on)-vs.-Manual
