CMRE 3.8L Ford SC Stage 2 Engine Program

COY MILLER RACE ENGINES

3.8L V6 FORD SC STAGE 2 ENGINE PROGRAM: The CMRE Stage 2 Super Coupe engine package is the result of hundreds of hours of extensive research and development with countless hours of flow testing and Dyno testing. Stage 2 SC porting consist of bowls reworked and short turn radius re-contoured on the intake & exhaust sides. Both intake and exhaust runners receive full porting & polishing. The chambers receive taller over size valve seats and are reworked to promote low valve lift flow & minimize valve shrouding. The chambers are then highly polished to help retain heat. CMRE valve seats are formed on a Winona CMC 30 cylinder head machining center with 3 angles and two radiuses with seat run outs of .001 or less, the valve seat heights are equalized to .002 and are fully blended. Valves are reworked to complement our seat design, as they too play a big part in air flow. All valve jobs are vacuum tested. Stage 2 SC heads are flow tested on our SuperFlow 600 computerized flow bench rd. 28" H20 to ensure they will flow the air required to make 480+ ft/ lbs of torque and 430+ HP.

Above parts and labor are included in the SC Stage 2 package

Typical CMRE Stage II engines dyno 430 to 450 HP @ 5200 RPM (16 psi boost ) and 480 to 500+ ft/lbs torque. Horsepower and and torque values are dependant upon external components utilized.

This engine is perfectly streetable, will "live" at this power level, and provides good fuel economy (depending on driving habits).
