Porting cylinder heads allows you to flow more air and unlock hidden performance potential. As a result, you can extract significant horsepower and torque gains. To port heads, it takes a craftsman's touch to shape the passages of the head for the most efficient airflow and effective combustion of the fuel charge. To verify this work, you need to flow test the heads on a flow bench. In this ground-breaking book, porting master and engine building wizard David Vizard covers all the nuances of porting heads and how to build an affordable flow bench to test the results.\u003c\/p\u003e \u003cp\u003ePorting cylinder heads is an art and a science. It's like sculpting a piece of clay into a glorious final form and, therefore, it demands the right tools, skills, and application of knowledge. With 50 years of experience and uncommon acumen, David Vizard explains the principles, philosophy, and techniques for extracting maximum performance from cylinder heads. AU the aspects of porting stock and aftertnarket heads in aluminum and cast iron are covered. Vizard explains how to optimize flow paths through the heads, past the valves, and into the combustion chamber. He covers blending the bowls, pocket porting, unshrouding the valves, porting the intake runners, and many other advanced procedures. All of these changes combine to produce optimal flow velocity through the engine for the maximum power. If you've always wanted to port your heads but didn't have information to confidently obtain the best results, now you do.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003ch3\u003eOther Details\u003c\/h3\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003ePublisher Code:\u003c\/div\u003e \u003cdiv\u003eCT-SA215\u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003eISBN 10:\u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003eISBN 13:\u003c\/div\u003e \u003cdiv\u003e9781934709641\u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003ePublished:\u003c\/div\u003e \u003cdiv\u003e2012\u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003eDimensions:\u003c\/div\u003e \u003cdiv\u003e220x275mm\u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003ePages:\u003c\/div\u003e \u003cdiv\u003e159\u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003eIllustrations:\u003c\/div\u003e \u003cdiv\u003eSoft Bound, colour ill\u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003eBarcode:\u003c\/div\u003e \u003cdiv\u003e9781934709641\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"Cartech Books","offers":[{"title":"Default Title","offer_id":47628019138780,"sku":"9781934709641","price":61.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0814\/8297\/3404\/files\/b15620b_david_vizards_port_flow_test__04190.1339460547.1280.1280.jpg?v=1772090619","url":"https:\/\/automotobookshop.com.au\/products\/david-vizards-how-to-port-flow-test-cylinder-heads","provider":"Automoto Bookshop","version":"1.0","type":"link"}
