How much water pressure you running on the brake? I have seen guys run 100psi on the brake water before to get some extra capacity from it they call it "dyno boost"
The dyno head can only manage low pressure. It does after all use wick seals for the water. Yes we run around 100psi to the feed valve. The dyno head is fjll of water at this high hp. The water feed rate is for cooling, once the head is full thats all shes got. The 100psi therefore is for flow rate for cooling nothing else. If l was to just fill the dyno head without replacing the water she would boil in seconds. Afterall the energy has to go somewhere. The dyno head at this hp heats up 22000 litres from 18 degrees to 47 degrees in around 60mins. And thats with a 3000kw cooling tower trying to cool it.
@@dynosmith2187 Yes I know dynos are an absorber and they can make a bunch of heat! Most of the smaller automotive style dynos only run 40-60psi thru the brake. the dyno I have is actually configured to run air pressure in the brake as well to load with because the air has much lower viscosity you can change the load a very small amount.
This channel is underrated Im glad I found it. These engines are monsters

still that MTU 16v4000 put down 6100!and that one only had 4 turbochargers not 6 like some i service 😎👍
Well yeah, that dyno is tiny compared to the engine!
Amazing to watch these giants. We all know by watching your videos that the smaller engines can pull down making these giants look even bigger, lol.
So what this is showing is the dyno can't really load the engine to its maximum?
max hp not torque. can pull down to 1650 rpm only. max hp at 1750 odd.
@@dynosmith2187 Thats a beast for sure.
