Gale gives an update on the dyno itself before sitting down to fire up the Duramax. We couldn’t reach the low pressure we were looking for from the fuel system. So we upgraded to the Aeromotive brushless pump with one of their regulators and got the 15 PSI. Watch Gale unbox the system.

One of the focuses for the first fire is to see if the engine has oil pressure. Thanks to the iDash monitor we can quickly see the oil pressure data. That’s just one of the many pieces of data we can get from the monitors. After the first fire, Gale decides it’s time to start tuning!

Stay tuned to see the monster truck engine firing up on this series.
