Splitpin additional engine bay ventilation

The Oily Bits S2 Specific Topics

Following Randy’s concern last year over elevated engine bay temperatures I have come up with this solution which also retains the boot.

The opening in the engine bay is 240mm x 75mm high and is located directly above the nearside wheel arch liner.

The battery is now located the other way around with the terminals inboard.

The mesh fitted to the rear is the same as Lotus supply and is available from Expamet www.expandedmetalcompany.co.uk
It is type HEX1 and comes in a 1250mm x 1250mm sheet, cost �22.79 per sheet.

I will have a Forcedfed intercooler fitted very soon now and this will allow the cooling air to easily exit the engine bay area.

The total additional weight is 2kg, but I have removed the heated rollers and the gravy boat holder!!! .

Hope you like the modification,

The total additional weight is 2kg, but I have removed huge fire extinguisher I had in boot "just in case "

Will there actually be any airflow through the vents though as the exit is where the low pressure is formed? (well I think it’s low pressure… it’s where all the road grime sticks anyway?)

6

If there is low pressure there (which I agree with) would it not help to draw hot air out?

Yes it will. The vents on the engine bay work in a similar way. Then the guys were testing it they found that opening the roof scoop hindered the cooling properties due to the disrupted airflow.
