Does anyone know of any facilities capable of testing natural gas engines up to 4000 bhp? I would imagine that the OEM's (Cat, Waukesha, Cameron, etc...) have them but I do not know of any independent facilities.
probably southwest research institute, too... I believe they have dynos for ship engines. SWRI.com... ah yes, here we go:
The Engine, Emissions and Vehicle Research Division maintains five large engine test cells with 6,000 brake horsepower capability and two large-bore, single-cylinder test cells.
My guess is that most of the independent engine consultants will have a "large engine" facility. We have one here that's got a 5000 bhp capacity. When it's running at full load you can see the steam from miles away.
I will not advertise or promote the company I work for, hence my statement that "most of the independent engine consultants" can do this work. But since you specifically asked, I work for Sir Harry in Shoreham-By-Sea.
