Turbo Stockers

[Jimi B]

In the 2010 rules amendments they have added for turbo stockers:

Turbocharger size will be verified by measuring the housing bore at the leading edge of the impeller wheel. The maximum diameter of the housing bore at the leading edge of the wheel may not exceed 2mm more than the maximum allowable turbocharger size
permitted.

By housing bore do the mean the inlet of the compressor housing? And they are measuring the id of the inlet right in front of the compressor wheel? Just making sure I am interpreting this correctly.
