This was a 2012 challenger with a 6 speed. It made right in line with what the 6 speed cars make on our dyno as a baseline. I think I could get a touch more out of it, but humidity is obscene today. I just thought I'd share since there's been a bit of debate as to the worthiness of a 6.4 cam swap.

That's awesome! I got my limiter removed so hopefully I will see some gains after a good tune.

Is this with or without the phase limiter?  Great job.

Look at the difference up top...  wow.

It's amazing. I knew it could be done. If these kind of options were available for VCT motors a couple of years ago, I might have kept my 2010 R/T instead of trading up. Not that I regret my choice

Cam and springs with a tune. Surprisingly easy tune too. No lockout. Subtle timing changes. Air fuel at 12.4 across the board 92 degrees at 50% humidity.

If this is without the limiter, perhaps we can put the nail in that coffin.

60 dollar cams rule!

Nice job.

Stock cam phaser

Simply amazing.

Sean I wanted mike to tune my 6.4 cam at CF but it did not happen. But for shits and giggles I down loaded the 91 diablo tune and the car ran much stronger. I would love to see if there was a difference on the dyno or if my car is just smoother with that canned tune.

I think you would have seen some good gains with a little more timing.

Glad to see this proven out. Need to see it on an auto, too, however.

It started loosing torque. Timing isn't always a matter of how much it will take. It's about what it likes.

I was talking about Phil's, he dyno'd a stock tune.

[Andy@PWR]

No loss down low. I like it when companies say "that cam is too big, you will need allot more converter because your going to lose all your torque. This one lost nothing and gained a ton. Thats amazing. Cant wait to see what our VVT 410ci stroker with Thitek heads and custom grind VVT camshaft does for you guys.

[lxmodguy]

Me too. That one will be fun. I was amazed by the pickup on this. I'm going to put one in my 300. I need some heads too.

[HemiSam]

Hoping this continues to prove out for the 2011+ folks.

 

Good stuff.

I already have a 6.4 cam sitting here to put into my 300.  I may pony up for some CNC heads and dig out some SRT manifolds I ported a while back and see what we can get out of one of these with bolt on goodies

Who toon's it?

So isn't there only a 100 hp difference between the 5.7 and the 392?

I tuned it

The rest is cubic inches and heads. Notice the 60ish ftlbs of torque missing from the 6.4
