More aggressive ramp rates result in increased cylinder fill rates. More air + more fuel = more power. While it takes longer to grind the cams, R\u0026amp;D has proven that the inverse radius created by the smaller grinding wheel on the opening side yields more horsepower in radius and roller rocker applications than the traditional large diameter grinding wheel.\u003cbr\u003e\u0026lt; br\u0026gt; \u003ceol\u003e \u003ceol\u003eAll BC cams are inspected with high-speed measuring gauges with sub-micron precision. The Adcole camshaft measurement system uses individual measuring heads for each cam journal and cam lobe, capturing one data point every 1\/10th of a degree at 0.01-micron resolution, or 3,600 data points per revolution. The Brian Crower model measures the camshaft for rise errors and chatter mark detection, capable of measuring 200 parts per hour.\u003cbr\u003e\u003cbr\u003e \u003ceol\u003e \u003ceol\u003eBrian Crower WRX \/ STi Street\/Race Spec Cams\u003cbr\u003e\u003cbr\u003e \u0026lt; eol\u0026gt; \u003ceol\u003eLonger duration profiles for higher RPM potential.

The STi version of the Impreza, from Subaru Tecnica International (STi), produced 280 PS (206 kW) from the factory and competed in the Group N class of various rally championships with almost no modifications, introduced in 1994 to great success. Introduced to the US in 2004, it is also highly popular in Japan as a high-performance machine with increased displacement. 2.5L (EJ257) equipped with AVCS.\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u0026lt; \/eol\u0026gt;\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":41419556749367,"sku":"BRCBC0622","price":1062.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0259\/7502\/9815\/files\/brian-crower-bri-bc0622-3807145603_73e8f341-53bf-4e85-89e5-9986404b5808.jpg?v=1785354052","url":"https:\/\/fivesquareusa.com\/en-om\/products\/brian-crower-stage-3-street-race-spec-camshafts-sti-ej257-bc0622","provider":"Shaft Shop","version":"1.0","type":"link"}
