Oh come on! It's 2:15 am EST and you couldn't post the video?!? You sir are such a tease.

Guess I shall have to wait until I get off work later this morning, get some rest and then I will see the awesomeness.

400WHP is very respectable, but that makes me wonder if the Ram intake has effected your dyno numbers that much. By no means am I downgrading your truck I promise, it's just interesting to me that Edmunds and Autoblog dyno'd a 392 and got nearly 450RWHP out of it with no mods. Some say it was a high dyno number by up to 30Hp, even so it's hard to imagine the Intake Manifold design nets gains of 20+RWHP, but if that was the case it makes me want to mount one onto my 5.7L to see what would happen lol I figured the with the factory Intake Manifold being for a truck, you'd just see your peak HP and Torque curves shifted for a better use on that platform. I didn't think it would actually take away that power from you, granted what you're making is no slouch either, you're putting down more power to the wheels than your old 5.7L made at the crank and still have a factory Intake Manifold....

those #s does sound overinflated for that stock 392.. Ive seen bone stock pulls on dynojets at around for 420/420 or so. Regardless they don't have the drivetrain loss either as a truck. SAE corrected Mike's power is what around 390/410? I agree, very respectable considering you probably can count in one hand in the eastern seaboard how many n/a gen 4 trucks making more power

Curious though, why would a truck have more power loss in the drivetrain? A 4x4 sure thanks to the transfer case for one, but I would think an R/T Ram would be just the same as a 392 Challenger considering the wheel base is similar and last I heard uses a 545RFE transmission as well. Only difference is that a 392 torque converter actually has a 2200 RPM stall where the R/T Ram is has a 26-2800 stall.

I wish ChevyKiller was still in town I keep wanting to steal his set up lol Damn Turbo Hemi's...

good point, he did run with SRT Rims. Bone stock 5.7 gen 4 trucks dynos showed up around 290 or so to whatever that drivetrain loss works out to. To be fair then, lets say 15% drivetrain loss from a fresh 392 from the factory rated at 470, what do you have? Never did get an opportunity to run into Gabe and his truck, while his truck was at Mikes place. Glad to hear you did
