the 384rwhp is pretty close to what I would expect it to do

 

Nothing, those are avg. numbers for a stock LS1 in an A4 Goat. Car had about 14k miles on it at that time. It is rated at 350 FWHP, so 67 hp lost in the drive train is about right, that is right around 19% drive train loss.

 

wow, that just seems like a lot of loss to me. was that partly because of IRS, the auto, both? Sorry, I haven't owned an auto is some time now.

I usually hear somewhere between 12-15%, so I thought the 5th gen would be around there too

 

correction numbers are required so that power numbers (preferably from the same dyno) can be compared to runs on different days. As you know, how much power an engine makes is directly related to the quality of air that it ingests. warmer air=less power higher humidy=less power lower barometric pressure=less power

correction factors are applied to adjust numbers so they can be comparable to engines dynoed at different temps, humidy levels, and barametric pressure levels

 

Yes, it is from the IRS and the A4. They say 12-15% loss through a M6 and 15-20% loss through a A4 for rule of thumb.

I trust those guys numbers...

 

Just realize that dynos or any measurement device may suffer measurement errors based on how they are made. Something as simple as a ruler may be off because of how its made. If the ruler is off, the foot it measures is not accurate. A ruler is a much more simple tool than a dynamometer. Based on how this equipment is made, there can be errors in the measured power output. That is why a correction factor must be applied.

Any measurement device is going to have some error that must be corrected for. The more complex the tool, the greater the chance for variation in the measurement.

 

That is 1 hp less than what I dynoed out at in an 08 vette bone stock...not bad at all.
