STU Question

Under 3.0 liters is STU, and STU does not explicitly list eligible cars. Turbo cars, however, use intake restrictors based on minimum weight chosen.

I suspect a well-built turbo car would kick ass in STU, eventually resulting in all turbo cars getting moved to STO...

Thanks! I think my car will fit into this class nicely. If I remember correctly the GCR is not very specific on the turbo inlet restrictor location. This can make a huge difference.
 
This is from the GCR.
Just pick a weight to run and select the appropriate restrictor size.
This applies to all Turbo cars in STU, not just the Porsche.

All turbocharged engines shall use a compressor inlet
restrictor/weight combination from the following table:

Inlet Restrictor (mm) Minimum Weight (lbs)
33.....................2200
35....................2475
37....................2770
39....................3100​

So the 944 will go from 46 mm to 37 in my case. It will be interesting to see how quickly the rules get tighten up.
