I was wondering if many guys took an active roll in heat reduction on the SHO. On my old forum for the G8, heat soak reduction was a hot item. Aftermarket made a "HSRK" heat soak reduction kit. Essentially it was a a pigtail I AT sensor you installed in the airflow source before the filter in the general stock position. This sensor was said react to temp much faster and was noticeable for use at track. Also in summer removal of the intake cover. On a G8 no big deal it made you see the big V8, on this sideways 6, not much to look at. Lower temp thermostat. Cowl rubber removal for airflow. We took off most of the rubber except where heater intake vents were so not suck hot air into vents making AC work harder. Also cut away some hood rubber to help direct airflow in. Also below the grill cut away some plastic let front air dam air from under car which then exited over the cowl. Not sure if it helped, but I did it anyway and there were no problems having done such.
Dont mess with the iat sensors...there are actually 4 iat sensors in the sho and alot of compensations are based on them...there is an ambiant air temp sensor, intake air temp by the filter and a charge air cooler sensor which is the tip sensor and iat2 which is manifold
You want the car to know the real temps on a boosted car...any car for that matter. So you dont want to manipulate the locations
