Running a stock hemi predator with small pipe. What max rpm's am I looking at for this motor and where would peak torque and hp be at? I don't usually run these motors this stock. Running an indoor event with some banking. Thanks in advance.
 
The engine is governed to either 3600 or 3800. Max power and torque is right at/near that point. I STRONGLY suggest for your health that you do NOT touch the governor to try to milk out extra RPM. The flywheels are notoriously prone to catastrophic disintegration at certain points above the set point. If you grab a 100$ billet flywheel you can rev till you please. Then with even slight mods the power band can blow you away. 20+ hp.
 
The rules are stock with governor removed, oil sensor cut with a wienie pipe and muffler. I run modified class with a hemi bottom end and rtc-8 head and it's a rocket with stock rod and flywheel. No tach on that kart. I'm sure it's at 5500-6000 on it. My search finds around 5100-550 rpms.
