It stays cool until it’s driven through the city then heats up. Temps steadily drop on the highway and will drop to around 130 even in the summer. Many cooling mods. With that, I got a new lid for the 2650 from DSX Tuning. Supposed to really bring out the blower whine. Only weighs like 7 pounds. I had Dave laser engrave the factory ZL1 blower lid design. Pretty happy with how it turned out. Putting it on tomorrow.

Lots of good info here.
With a 3" upper, mine cruises at 104F and reaches 115 as it coasts after a pull. No problem here.
With a 2.75" upper, it cruises at 90F and hits 140 at redline.
You say lots of cooling mods, what are they? Mine is just a 7.5 gal tank with Davies Craig 8160 pump. We'll see how much the fan and pump controller helps shortly.
Is your new lid just for sound or does it also help with heat?
