I have the blanket and spacers on my Hellcat and it definitely keeps the temperatures down. I never put the car on a dyno so i couldn't tell you with any certainty how much horsepower i gained. I've read that it bumps up the horsepower by as much as 40.

The temperatures do run cooler therefore it stands to reason that the car will adjust the timing and make more power. My Hellcat does feels like it pulls a bit stronger than before i did the install.

MY personal opinion is that if you have to pay someone to do the work for the install than it's not worth it. It's cheap horsepower, the kit itself if cheap but if you have to pay labor to have it installed, it kind of defeats the purpose.
