My stock dyno

This is a month old, but finally got time to post it. The numbers on the higher side from the stock dynos that I looked at.

looks about just in line with the stock 335i that we dynoed today!

By the graph going all the way to 7000 rpm, looks to be a 6MT and on 93 Octane I presume?
What were the temps during testing?

That dyno is very optimistic for SAE rating.
Even on the more optimistic STD ratings, it would be a bit optimistic. A recalibration of the dyno is apparently needed.

Yes its a 6MT but it was on 92 octane. It was done at the beginning of August so I would say it was quite warm. It was a while ago so I don't recall the exact temperature.

jpsimon - What was the today's temp in your area? It was quite in the 50s here so I want to compare how my car did in a hot summer day vs. the car dyno'd today. I know SAE numbers are supposed to compensate for that but I still think that temp makes a huge difference on a turbo cars dyno.

Looks right to me. This summer, on 93oct/Dynojet/90F/38% Humidity:

Edit: 1 small fan here, too.

Thats almost exactly what I got in July in Orlando on 93 octane 6MT. (286whp/295wtq) - SAE smoothing 0 1.00 correction factor 94 degrees, 1 small fan

it was around 60-65°

looking good!
I know the E93s shouldn't differ, but anyone have a dyno?
