    Saw a post showing an ice bag on an intake mfd and made me wonder if the Hellcat has power robbing intake system heating issues like Mustangs. A friends Shelby 500 made 690 Hp on first dyno run but that dropped by about 40 Hp on each of the next two subsequent pulls. And there is nothing he can do about it.

    Does the Hellcat have similar issue??

    Thx, Bob

    I have both cars, there is a cooler for the charger on the Dodge, not the Ford. both engine bays get really hot. But I believe the Hellcat is more set up for heat, with better cooling system.

    Just did some runs at the strip last night. Not back to back but fairly close to each other. All my times where within 2/10ths. And that's with a stick.

    Yes, all cars heat soak.
    The hellcat is engineered so that when the engine gets to operational temperature that the performance will be fairly consistent in running the 1/8 or 1/4 mile. We see a drop of 30 HP from cold to hot on the dyno, that's why we try and tune at 203* as the car will be more consistent .

    I'll say yes went to track yesterday 80 degree runs were decent. 93 degree runs were awful. Intake temps were 150.

    The Shelby is inherently prone to more heat soak because its Roots blower design makes more heat and has only a single intercooler.

    Absolutely, but its not near as bad as some cars. Dodge did a great job with the cooling system and hood design to remove heat.

    image.jpeg image.jpeg 93 degrees out 40% humidity. Best run. With 60 in 1.6 which I think best 60 for mt hellcat posted I should've ran real low 11s. Intake temp was 172 lol. Waste of good 60 foot. Heat affects this car a lot. Think fall gonna be best times
