I finally strapped my 135i onto the dyno after fine-tuning the
new single turbo setup and am thrilled with the results. I did a handful of pulls at various power levels and attached the logs below. This should give everyone a good idea of what a properly set-up 6266 can do from low boost to high boost on an N54.
All pulls done in 4th gear (manual transmission). DynoJet with STD correction set at 5.

After enjoying the car for a few months, I’ve been curious what kind of power it’s actually making to the wheels. So, I went ahead and scheduled a dyno appointment.
Here is another video, with a loud backfire out of my midpipe (axleback section removed after it started rubbing).
The best numbers were 448whp and 501wtq with SAE correction. It looks like all the N54 guys use STD correction instead and that converts to about
468whp and 523wtq!
Here are my modifications to reach this power:

Late Model Throttle was hosting a dyno day at their shop in Waukesha, Wisconsin. Knowing that there would be a DynoJet and some cool cars, I decided to sign up!
The car was strapped on and put down 448whp and 501wtq with SAE correction. However, all of the N54 guys use STD correction and that converts to about
468whp and 523wtq!

Beyond Redline hosted a dyno day this weekend and I wanted to find out what the car was putting down before I started modding it.
For only $60, why not?
She put down 283whp and 292wtq with only a K&N drop-in air filter and Riss Racing 3″ catback exhaust.
JB4 and catless downpipes coming soon…
