FrankenTurbo F21 First Run

Got the S4 out on the road today with the first version of the tune to shake down the parts and make sure the car is running properly. Got on the throttle briefly to see how the boost comes on.

My intent is to operate around the same boost profile as I had with the K04’s in order to gather some comparison pressure and temperature data, so this will need to be toned down a little.  Then I’ll start to up the boost level and see what comes of it.

Moving onto FrankenTurbo F21’s

I’m getting started with removing the BW K04’s to replace them with FrankenTurbo’s F21 Mixed Flow turbine wheel turbochargers.

I’m knocking out a little bit on the car each evening.  Putting up insulation in the garage is paying off big time now that bitter cold temperatures have arrived.
