TEST EXAMPLE 10 - FIGURE 15
This is a Dyno run on a 287 cubic inch twin turbo motor with dual waste gates controlled with
manifold pressure. The springs gave a minimum of 18psi of boost. This shows the PID of the dyno
tuned very close and the PID of the PN 7562 very close to optimum also. Maximum boost on this
engine was about 33psi using manifold pressure for waste gate control. C
O
2 would be required to
increase the boost pressure due to the high exhaust pressure making 1,650hp at 33psi. This run
produced about 1,550hp at 31psi boost.
