I thought I'd throw this out there for suggestions. Those people I've already asked, please don't feel offended that I'm still asking others. I do value your input but want to put it out to a wider audience and maybe help those with turbo hybrids that may find they have the same problem as me.
Anyway, the car has an ally rad and the core is exactly the size of the hole in the rad support panel. A large kenlow push fan is then mounted in the hole in the support panel. The intercooler is then in front of the panel and exactly cover the support panel hole with no gaps around the outside. The car has no oil cooler and the turbos are water cooled.
Under normal driving and in traffic it stays at the thermostat opening temp ans I only need the fan on if stationary after spirited driving. At normal motorway and high speed driving it's also OK. The track sessions at Mallory also showed no increase in temperature throughout the session. Now at Spa, at the end of the long uphill straight, on full throttle and boost it got hot and stayed hot for the next few turns. Only cooling down by backing off and coasting in 5th. This really messed up my fun and I need to find a solution for next year.
I'm guessing the turbos are producing a lot of heat which is being transferred into the water and also the heat from the intercooler isn't helping. I've no idea how hot intercoolers actually get so I don't know how much this could be contributing. I could do with an oil cooler but the only place for this is near the rad so this could actually make matters worst. I'd looked at tilting the intercooler forward to allow air to pass around it and through the rad but from what I've read this could make the airflow worst due to turbulence.
