Simulation Data
 Modeled on the H-Engine / made by GM
(It is rated at 6300 Bhp at 1000 rpm)
compiled by Mark Engelmann / 2-23-06
1st line is the baseline engine
2nd line is dual pressure intake engine
Comparing Power
Valve timing adjusted to get maximum power for baseline engine
(See next page for more information on valve setup)
