Coupe Engine Bay Temperature
All
Wondering what other coupe owners have done regarding engine bay temperature management. Took the car for 100+ mile highway drive today. I have a GM427LS engine in there was was running around 192F on the highway then would get to to 203F when I'm stopped at lights. Fans come on ok and keep the engine itself cool.
The problem is that the engine bay is very hot. I've seen some coupe owners install vents in the hood. Is that the most effective way of getting the temperatures down ? Adding vents to an already painted car would be challenging. Any other tricks ?
thanks!
