I saw a 6.1 Hemi for $2500 w/computer the other day on craigslist...isnt there anymore though. That would be a nice addition if I had that much extra lying around the sock drawer.

 

That's ricer talk...how dare you

 

you know I know this is kinda off subject a little but it goes with the 4.7 vs the hemi, my 05 4.7 seemed to take in a lot more air than my 07 hemi, they both had the k&n 77 series intake and the hemi is quiet and the 4.7 you could really hear it sucking sounded awsome why is it so different

 

Not that it makes a huge difference, but the 4.7 was 235hp, not 220hp in 2007, so if the newer one is 300hp, they really gained 65 horses. Seems like a more reasonable jump.

 

The 4.7L was working alot harder to move the truck than the Hemi!!

 

Isn't it 310hp?

 

Yeah those numbers were to the flywheel. The nice thing about freeing up the intake and exhuast though is that you get a longer lasting engine that is going to get better mpg's. My 05 4.7 QCSB ram 4x4, with 33'' A/T tires, gets just over 14mpgs with more city vs. highway driving. I am always in town stopping at all of those stupid lights and stop signs. The MPG should make another jump because I just finished installing the True Flow XDI intake last night. It was already increased in mileage vs. stock over the first 70 miles of the tank and I was slamming the gas pedal to hear my new toy roar.

 

08 4.7L is 310hp/330lb/ft
08 5.7L is 345hp/375lb/ft

 

And the 09 5.7 is 383hp/404tq.

 

hey lxman, my 05 was a rcsb and it was way louder even on start up, my 07 hemi is a qcsb so don't think the 4.7 was working that hard just seems like the bigger engine would pull more air?
