Degree a E-303 for more HORSEPOWER

[SpeedRacerXTC]

Thanks for checking that out. I have used desktop dyno before but it does not play out well for Vipers. Mostly because of the restrictive intake manifold, there are no flow formulas for it.


I do know that in my particular application, the E303 did make great power. Also noted that several people I know with the cam do retard it for their preference. In mine, where I am using the top gears more than the lower ones for acceleration, I needed the cam to make its peak power closer to 4500 rather than 5800 rpm. This gave the engine a much broader torque curve and I would be interested to see how the desktop dyno indeed graphed that out.

I will certainly dyno tune everything now. Back in the day when I had that combo, the only dynos available were Clayton Water Dynos. We pegged those at well over 300 hp!!
