Which model does this entry cover?
It groups units recorded under the generation name rather than a specific version. Our history has separate entries for the GT3, Turbo and others.
Which engine gains most?
The turbocharged units, by a clear margin. The naturally aspirated engines gain considerably less, since there is no boost to adjust.
Should I check other entries too?
Yes. Our 991 entries cover the GT3, GT3 RS, Turbo and Turbo S separately.
