There's no question that Atom 4 coolant temps can be a real problem on track, but it only seems to be once they reach 100degC that performance starts to be impacted. This issue has been highlighted previously, notably by Simon Hart, and he did a lot of work to try to get the temps down, but sold his car before all the work he'd done could be properly evaluated in terms of it's effectiveness.
Latterly, in conjunction with a couple Atom 4 owners and the invaluable services of Corten Miller Motorsport, I've been associated with steps to adopt some of what Simon did/suggested together with some additional measures, several of which are ongoing. Currently we feel the main issue is that the radiator simply isn't seeing sufficient airflow due to the relatively small cross-section area of the 4's nose cone opening. More on efforts to overcome this will be posted as and when further progress is made.
