this in itself may sound irrelevant but the heat soak effect means that it takes 2-3 seconds of charge air on the sensor (i.e NON-closed throttle) before the heat soaking is overcome and the sensor believes IAT has dropped. during that time period the ecu is retarding timing to prevent heat induced det. probably not so significant on track but definately a consideration if you want a quick getaway from the lights
To be fair a kit car with a yb crammed in it and they are squeezed in there very very tightly will have very different under bonnet temps to a sierra. Myself it was no issue having no vents rod I can see having an argument as he runs into problems no one else ever will as his torque and horse power levels have not been matched. But as a road car I'll be fine
