Feeling hosed

Seeing high temps here in AZ, considering a swirl header tank to assist, in addition to the 3 pass proRad I currently have.

I'm seeing a couple of places selling silicone hoses, one shop has 2, another shop has every hose on the car.

Folks that are running higher pressures than stock...did you replace your stock hoses? Did you replace all of them, or just 2?

If someone is replacing only 2 of the hoses to handle the pressure, how do the other stock hoses that aren't replaced keep up?

Sector 111 sells a single pass which allows more airflow
over the three pass because it is thinner. A swirl pot (radium)
will not bring down coolant temps much. The radium tank
isn't a true swirl pot according to BOE, but that is
just hearsay. The rubber hoses at the radiator are fine so
long as the clamps are torqued sufficiently. I had a 2006 Elise and
now a 2008 Exige with stock radiator/rubber hoses and never had leaks.
The stock radiator is more than adequate for street driving and I have never
had an issue with overheating on the track either. Don't spend a ton of money
until you determine that there is no air in the system, the thermostat is working properly
and the water pump isn't failing.....-Robert

My comment assumes your Exige is making roughly stock power levels.

2006 Elise ST (someone else has it now . . . )
2008 Exige S240 ST
