Very hot and bothered

[blitzracing]

A friends 5ltr runs at 100'c all the time- the rad' is brand new, as the thermostat (large bore), and both fans are on full speed all the time. The engine bay is like a warp core heat wise, and it simply looks like hot air cant get out of the engine bay. Im going to have a play with the fueling to see if I can cool the catalyst as this cant help but Is the 5lt cooling system really that marginal?

Quick update- ripping off the number plate has made a significant difference- so time for a splitter to force more air in in the air intake and cut the number plate down is size...

Thanks for the thoughts so far- basically there has been a massive drop in temp with the number plate removed, plus we spent more time bleeding the system- so plan of action is to fit a splitter to force more air in, and make the number plate as small as legally possible to start with. Also worth moving the bonnet clamps up a bit at the rear to increase the air gap. Im still going to have a play with the fueling to see if I can reduce the cat' temp, as it should also improve the MPG. Id recommend COGs recommendation of removing the ported vacuum as well, as I cant find a downside on this mod what so ever.

Ill pop Rovergauge on there to check- but my spider senses tell me this is really hot, and the engine starts to stall badly as it reaches an indicated 100'c. Im not loosening the cap to find out it boils ! Mind you maybe I'm just used to a nice Ginetta cooling system that never goes above 85'c whatever the ambient temp.

The fans are on full time as we shorted the otter switches to try and get maximum air through the engine bay so we cant use that as a temperature reading.

Nope- crossed wires (literally) , we shorted the otter switch on purpose trying to get the temperature down on a very hot blast around the Brecon Beacons, so its not part of the issue.
