Obviously we have cooling issues with our cars on track days. Even with oil coolers, intercoolers and radiators it seems to still be an issue. I regularly autocross mine and even then experienced elevated oil temps according to the dummy gauge.

Given my regular track car has been a single cam Honda, I don't need a high horsepower car to have fun.

Wouldn't a low boost tune solve our heat issues? In all my years of owning this car I've never heard of such a thing. Wouldn't this be an easy fix?

Mind you I'm no expert. Most of my knowledge is in suspension tuning and I know nothing about engine management. Would it be as easy as buying an AccessPort and having someone turn down the boost with a new tune?

Pretty much, I know stratified offers an eco tune, I have it, but hardly ever use it. Limits boost to 15psi normally but they can set it lower if you like.

Power output isn't the issue. Cooling is the issue. Specifically, air flow to the radiator. In stock form the grill shutters, intercooler, and AC condenser sit in front of the radiator, impeding airflow to a degree. An aftermarket radiator wont help if it isn't receiving sufficient airflow. Most aftermarket intercoolers don't help improve airflow to the radiator even though most of them require removing the grill shutters; Many of them make it worse since they are much thicker than the OEM unit. Most people overlook this aspect.

mountune's intercooler is made with track racing in mind, to help airflow to all the heat exchangers behind it.
100% agree, and its the only one to my knowledge that was engineered with this goal in mind.

I have the mountune intercooler and track often. Before the mountune, I'd see 230*+ coolant temps on track. Since adding the mountune, I see about 210-215* in the same conditions on the same track. This is usually a peak temp down a long straight. Coolant temps recover to high 190*s much more quickly since adding the mountune. With the OEM intercooler, they wouldn't fully recover in time before rising again.. and lap after lap coolant temps would creep up until reaching the 230*+ range.

^^^ That's good info right there, not only is the price very competitive but being track friendly is a plus. I thought it was just kinda ugly and an odd 2" deep design but i see there's a reason behind it.

The mountune fmic is made by Pro alloy in the UK. Pro Alloy Motorsport - Specialist alloy components - Focus ST 2.0 Ecoboost Intercooler Kit (ST3)
They also advertise it with the better airflow (compared to other aftermarket fmics) to the radiator.
Does not block the air flow to the water cooling radiator like some other aftermarket designs This is because our cooler utilises a THINNER core than standard to aid the ambient air flow whilst increasing the internal air flow with our taller core by 16%
But come to think about it, my Airtec IC is also a wee bit thinner than standard.
