HOT FEET

[MichaelD]

My car is a 98 Caterham DeDion, LHD, 210 HP Zetec, Jet Coated headers (silver finish has burned off) I will need to replace it with the Black Jet Coat. Coolant is water with Water Wetter,

 

Placed foam around radiator to force all cool air entering nosecone through radiator. Placed foam on both sides and top of the transmission to keep hot air out of the transmission tunnel.

 

Pics attached.

 

Tested with a dual probe meat thermometer from Polder. One probe in engine bay and one probe in footwell. Ambiant temp ranged from about 95 F

 

RUN 1 - Engine at 3,500 RPM for ten minutes, Water temp 80 C., probe attached to master cylinder in engine bay.

Engine bay 149 F

Driver footwell 119 F

Passenger footwell 109 F

 

 

RUN 2 - Engine at 3,500 RPM for ten minutes, Water temp 80 C, added foan to the outside side of footwells and moved the probe to in front of drivers foot box..

Engine bay 167 F

Driver footwell 107 F

Passenger footwell 106 F

 

The added foam to the outside side of the footwell seems to have lowered the footwell temps by 12 degrees on the drivers side and 3 degrees on the passenger side.

 

A simple touch test revealed that most heat in foot well is now radiating from the tops of the footwell and the bulkhead. This ared is not covered by the reflective heat shield. I just bhate to stick stuff on the clean aluminum :-(

 

I have run out of time to perform test without any foam. There's always tomorrow.

 

I will trt to upload photos.

As I noted a week or 2 ago on the Se7ens mailing list, I took temps in my 1700cc Crossflow with just a handheld digital room thermometer. On a 80 degree day with the top off and side curtains up:

 

Passenger side 85 degrees

Driver's side- 111 degrees on my lap with side curtain fastened;

Driver's side- 101 on my lap with the bottom 1/2 of the side curtain flipped completely up (where air pressure holds it in place @ 70 mph ).

All temps measured in the shade, on a mostly sunny day.

 

Toasty.

 

On a really hot day, I am sure the #'s would be much higher.
