Thanks

Have been discussing the heat problem primarily with owners of 500E's
There was one in Japan who has used wide louvers in the front of the hood, for intake cooling, but location would not allow extraction.

If I use the 280Z extractors they will be located as Mosselman did on the Silver Arrows.

Not worried as much about heat under driving conditions, more at idle and after shut down.

One 500E owner was thinking about exhausting via a fan.
I will be trying this probably next week.
Will be using an inline blower of the type that NASCAR uses to cool brakes.
It's tubular, about 7" long, with a 4" intake and a 3" discharge and moves 270CFM.

I'll initially use an inline thermal disc thermostat to turn on around 150F and off at 135F.
I need first to read spot temps with an infrared thermometer.

Considering locating the blower on the rear bulkhead at the centerline of the engine.
Will use 3" duct to the lower chassis on the intake side of the engine.
This should create a negative pressure to draw the rising heat from the turbo heat shields.

Have you considered this method ?

Thanks
