So 600 hp on stock rods is possible as long as it is not an endurance road race car being spun at 6-8k for hours on end. Perfect, as Bryans car is a street car.
If I had the financial backing Electramitive had I would not use stock rods either or even cranks. Money makes those decisions alot easier.
I may be wrong, let me know, but I would think that Bryans engine only seeing 17 psi would be less detrimental to longivity than say another engine seeing 22 psi (mine) and making less horsepower but similar torque. The load on the internals would be the same at peak torque, his just breathes better up top making more power. I would also think 22 psi would easily have him to 600 crank. I ran 22 psi when I road raced and never had a rod failure and it saw some revs.
