I have been looking at older porsches and not to many are north of 180hp
first 911 130hp next 1971 911S 180hp 2300lbs then 1973 911ST 270HP @8000rpm fewq cars made.
Most 1973RS had 210hp with 2300lbs by 1977 still around 200-210hp.
P attempted the to strip weight off of some models too.
So if you have a lighter car and you get N/A 180-200hp you have a good ratio of hp to weight IMO. And Then there is Marty and Bob
