Alot of your problem was probably the 114psi. Rule of thumb is 10psi for every 1000 rpm. Unless you have stroked your motor beyond belief or turning it 11,000rpms you shouldnt need that much psi. If your motor is fairly new and your not using a remote filter or cooler a standard pump at 70psi will be more then you need. A high volume pump is probably not needed in your case, its just creating heat and robbing horsepower.
