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!!!!

That is better. I was worried for a second. I am glad you got it flying. I miss that speed it is sharp.

I am very happy with those numbers. I just have some grudge matches that are coming up! Do you think if I run race gas, like u4, I can get it to 57? I need a wheele bar.

You could get more power with race fuel, but I would recommend either running it on the fuel that it was dyno'd with, or dyno it with the fuel you're going to run it with.

It is nice to put out 56+ horses on cheapo 91 octane.
