remote radiator affecting turbocharged diesel genset?
(OP)
We are spec'ing three 1000 kVA 600V diesel gensets, one of the manufacturers siad that remoting the radiator might cause prblems with the turbocharger due to cooling lag time. Any experience out there?

Add some salt to whatever else that guy says.

Where it appears to be an issue is for any sort of block load on the engine, its made worse if there isn't much load on the engine at the time.
The sites with most issues have long lines with remote mount radiators.

If your genset supplier is hesitant to remote the radiator, you might want to listen.

Cooling lag is a new one on me, the primary concern would be the overall pressure drop, frankly a long return run from a remote charge air cooler can actually help further lower inlet air temp.
The other drawback of remote mounting a charge air cooler a long distance is you can get a pressure lag effect, and may affect transient response.
I've done a number of units with charge air coolers (combination units actually) mounted as far as 50 feet away with no problems. We did four units near your size about 5 years ago that the cooler units were about 90 feet away from the engine, all of those units had an issue with transient response, but the system operation could live with the lower response and the customer accepted the system as installed.
Hope that helps, Mike L.

That said, remote mounting jacket water cooling systems doesn't present a problem providing all the appropriate considerations have been taken into account for size of coolant pipelines.
All of our power stations have remote mount jacket water systems above 250kW engine size.
