Stock 1LE big loss of power
Hey Guys,
I've been lurking for a while so thanks ahead of time for the answers. I have 2018 ZL1 1LE with 5000 miles that I do HPDE events. Anyway I have lost a bunch of power for no reason. I went from doing 151mph at Roebling Road to now topping out at 135mpg. Same warm weather and same settings on PTM, ETC. It just feels like I have 150HP less!!! Today a Ford Mustang Shelby 350 was drafting behind me. Usually not even close. No codes, three tanks of gas from different locations and it runs/sounds fine. Going to a dealer tomorrow, but has anyone had the same problem? |

Maybe you have air in the supercharger coolant lines. Many of us have gone out and purchased a aftermarket solution for a supercharger coolant reservoir as that will make sure the line is always clear of any air.
You can go to the dealer and see if they can perform a bleed for the supercharger or do it yourself. As this will make the car feel sluggish with no codes or anything. |

That is engine coolant not SC coolant. Intercooler is also a closed loop separate from engine coolant. Stock its a pain in the ass to bleed. If you have the ability to log with hp tuners, you can check your IAT/MAT temps which would confirm if you have a heat soak type of issue. |

There's no easy access tank to add fluid into, but there is a fitting. No need to visit the dealer if you are good with tools: https://www.camaro6.com/forums/showp...8&postcount=12 If not, you can buy one of these for $15 and use a 2L bottle as a funnel: https://dedicatedmotorsports.com/lt4...-adapter-tool/ |

If I use the aftermarket adapter and use the bottle as a funnel, how do I refill it? Do I just add coolant to the bottle and run the car until no more coolant goes in? How long do I run the car for?

You can run the car, or do like I do and jump the intercooler pump circuit.
