Built around OEM as cast port heads, VCT-friendly, 5,000–7,700 rpm sweet spot; OEM valve springs OK for NA and blower, turbo compatible with an upgraded valve spring.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIf you daily it and beat on it on weekends, this is your cam. The GSC S1 profile is engineered to wake up midrange and carry power cleanly to 7,700 rpm while keeping drivability intact. Profiles are modeled against real Gen 3 port behavior and rocker geometry, then cut from our U.S.-made forged billet blanks and finished with BLACK ISE for reduced friction and long life. Designed for stock (as-cast) heads and pump gas, race fuel, or ethanol blends (E85\/E90). Tuners keep VCT online for a civilized idle and crisp throttle; when you go WOT, it hits harder across the usable band—not just at the peak.\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eDirect Injection note:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethe high-pressure fuel pump (DI\/HPFP) lobe is maintained to OEM specification—stroke and timing are retained for proper pump operation.\u003c\/p\u003e\n\u003cp\u003eThe S1 also shines on the road course with naturally aspirated setups—delivering crisp throttle response out of corners and a broad, usable powerband that pulls cleanly without sacrificing drivability.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eFuel\u003c\/div\u003e\n\u003cdiv\u003ePump \/ Race \/ E85–E90\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eRPM Band\u003c\/div\u003e\n\u003cdiv\u003e5,000–7,700 rpm (≈7,500 peak)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eValve Springs\u003c\/div\u003e\n\u003cdiv\u003eOEM OK (NA\/SC) · Turbo → GSC springs\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eUse Case\u003c\/div\u003e\n\u003cdiv\u003eStreet\/Strip + NA road course\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eDI Pump Lobe\u003c\/div\u003e\n\u003cdiv\u003eOEM geometry retained (HPFP compatible)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse case:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDrop-in \u0026amp;
