Well, tonight was a great night on the dyno! Speedracer's engine threw down our largest number thus far... 56.5hp! Here was the setup:
Dynojet in ground chassis dyno (4000lb rollers) (Our usual dyno and operator)
450CP, Timbo stroker crank (467cc) (old piston, new rings and a hone)
Timbo porting from back in the day (Cory Jenkins' old engine)
Port matched throttle body
Cyclone Velocity Stack
Uni TRX250R Air Filter
HMF Ironman Slip-On
Stock Short Runner Stainless Header
113I/108E Cam Timing (Timing found was 104.5I/104.5E)
Auto Zone Non-Detergent Engine Oil (Break In Oil)
Red Line Lightweight Shockproof Gear Oil (Tranny)
Primary Drive Non O-Ring Chain
13/40 gearing (I think it's a 40T...)
This engine ran great, pulls HARD on the dyno. 35.7 ft. lbs. of torque! Even the dyno operator was impressed!
Good luck drag racing it Dave!!!!
