"A basic rule of HP increase is for every Liter of displacement you will get 4 HP. So if you have a 3.0 L ford you will get about 12 hp, if you have a 4.6 L Chev you will get about 17 hp and so on."....????????????

I'm not sure how to answer that one, but I can tell you how to figure your power-to-weight ratio. In other words: How much HP per pound of your vehicle. Take total HP divided by the weight of the car times 100.

 

Couple examples:

Z34: 200 HP divided by 3340lbs times 100 = 5.99HP per pound, that's pretty good power.

 

Euro 3.1L 140HP divided by 3269lbs times 100 = 4.28HP per pound.

How many 12hp Ford Tauruses have you seen? The Duratec 3.0L V6 has 200hp Ford's modular SOHC 2v/cylinder 4.6L V8 has 260hp/302 lb-ft in some applications...I'm not sure I understood your question.

I don't think your formula for HP increase is correct. There are too many factors involved. Original size of the engine, manufacturer of the engine, valvetrain, compression ratio, fuel octane rating, etc.
