2009 Super Street rules SS

Whats it say?

Turbocharger: Vehicles are limited to two turbochargers only. Single turbos are unlimited. For multiple turbos, the inducer bore on the atmosphere compressor housing(s) may be no larger than 3.2 inches measured at the smallest diameter area
of the compressor wheel. A bushing may be used to downsize the compressor housing ahead of the wheel. If a bushing is used, it must be round, at least 3/4 inch long, mounted within 0.050 inch of the compressor wheel, and the inside diameter
of the bushing may not exceed the 3.2 inch limit. If you have any questions regarding the construction of a bushing, contact NADM Technical Services before the season starts. A stock map width enhancement (MWE) groove is permitted. No MWE groove may be wider than 1/4 inch. All provisions allowing air to the wheel other than via the bore and MWE grooves are prohibited. The inducer bore will be measured using a 3.25 inch plug.
 
so your saying we have to use turbos only then??
Gene you sure like to ruin my idea's!
 
I think your looking at it all wrong Joe, You can use any number and size supercharger. Its not a turbo so there is no regulation.
 
Now why would you want to procharge a diesel????
