Hi all
Over the weekend I re-fitted the plastic splash guard under the engine and the front brake ducts, which I haven't run on the car in 3 years since doing my M30 swap. Surprisingly, the car now appears to be running cooler? This seems counter-intuitive to me as the guard restricts airflow into the engine bay and I'd left it off deliberately thinking that it would help with keeping the engine cool.
Does anyone have an explanation for this?
The only thing I can think of is that by restricting the airflow under the car, the fan is actually working more efficiently as there's less turbulent air behind the radiator?
Cheers
Luke
