Video: Arrington & Holley Tune Up 2015 Hellcat Engine
It looks like Dodge underrated the stock Hellcat engine at 707hp and it's really 773 hp+/-
Yeah. Awesome. Til it melts 2 pistons after 3 1/8th mile passes. I wouldn't let them tune a fish.
They also are using 6300 rpm as the limit. Getting some power right there. Good to see Holley is working on something for a non OEM install.
Agree leaving sc stock.
You have a beef with Holley? (They're using Arrington's facilities and the engine they bought.)
Nope. But if Arrington burnt to the ground I'd bring the marshmallows
And Holley owns Diablo
I'm a skeptic on these massive conversions--my experience has been that the increases may come at other losses like total driveability and low end response--the cost benefit may be low and the application is only as good as the installer and the final tune--weight reduction will yeild quicker results--it has always been about hp/weight ratio. If I do anything, it would be a small nitorus app with "progressive" stages--will let you know if I do it.
