What Makes the Power:
Well, if youâ€™ll remember the HF motor has an 8-valve head, which is great for fuel economy and miserable for performance. The 16-valve head will raise compression substantially creating a surprisingly powerful hybrid. Now, what kind of numbers can you expect from this setup? A friend of mine recently used a similar setup and put down 112, 109 to the wheels. With this type of power, look to be pulling on GSRâ€™s, Civic Siâ€™s and even the occasional unsuspecting Type R owner.
