From the above can we take it that upgrading is not required or is it just luck?
It's interesting to see but yes there have been a few engines on engine dyno's running 500hp, 522hp, 550hp and just under 600hp all on standard pumps. These have not failed BUT some have since when they were driven in the car.
It's a difficult one to address but this test is interesting to say the least
