On a supercharger for every 100 HP gained it takes about 30 HP at the crank to generate it. For a turbo-charger it takes about 5 HP of back-pressure to develop 100 HP.
Agreed, Go M112 from the 03-04 Cobra Mustang.. Won't regret it. And if you set it up right, You can do a set of the right roller rockers that will NOT require a cam, you can use the stock profile cam, add a larger fuel rail and pump, and run it basically off stock ECU.
Your original rockers should be 1.5:1 ratio, plus they're not roller. Installing a 1.8:1 roller rocker.. you'll be gaining 80,000 thou lift at the valve, not changing the duration at all mind you which will increase the air flow coming into the engine. [much as a cam does] but without the added expense of upgrading a cam, upgrading the ECU or additional costly shop rates. most people can install these on their own.
I'd have to check to see what upgraded options I may have on timing chains or even the possibility of a double timing chain like whats offered for the OHV.
