Posts with a significant portion of the discussion involving FrankenTurbo products
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.
Finished reinstalling the engine today and started it up with the FrankenTurbo F21’s in the mix. I’m still on the legacy tune from the K04’s and larger injectors so I just did a leak check and let it idle for a couple of minutes.
[KGVID]https://myaudis4.com/wp-content/uploads/ft_startup.mov[/KGVID]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.
