Dynorun 3:2

Red = DRP high performance stage 2 heads, worn Webcam cams, URM Racing 4 into 2 into 1 exhaust system, MAC megaphone muffler, special competition baffle, open airfilter.
But before rejetting to #132 & removed snorkels.
Blue = Same as Dynorun 3:1 Red.

This graph shows that the rejetting and removal of the snorkels increased the power and torque all over the power band, specially at the midrange band 5000-8500 rpm. But it dropped 3-4 bhp at the top, probably due to a little rich jetting and bad flowing muffler. Note, still with bad Webcams.


 

Dynorun 3:3

Blue = Same as Dynorun 2.
Green = Same as Dynorun 3:2 Red.
Red = Same as Dynorun 3:1 Red & Dynorun 3:2 Blue.

Same as Dynorun 3:3 - torque only.
