4.7 Underrated

[Jeepwalker]

Good engines. I d be fine having one in a Grand Cherokee or any other car but the Ram is too heavy for a V6 and just like the V8 power for it. Maybe if it had twin turbos lol.

The 4.7 was a V8. Maybe you're confusing it with the 3.6L V6.

We're all revising history here. The 4.7L V8 has been out of Rams for a long time. This isn't an anti-Hemi thread. Obviously the 5.7 has more power, it's a fantastic engine. It's always good to have options to fit an owner's application. The beauty of the 4.7 was it's torque came in down low where it was really usable day to day. Actually more than the 5.7 down low. In the 2010 Ram for example see torque figures below. And IDT (correct me if I'm wrong) the 4.7L had cylinder deactivation. So when you're driving down the road and needed to accelerate, you have instant throttle response. Not that half-second of dogginess ....waiting for the 5.7's cylinders to kick back in.

Torque:
1600 RPM
4.7 ~ 260
5.7 ~ 225

2000 RPM
4.7 ~ 290
5.7 ~ 240

2800 RPM
4.7 ~ 295
5.7 ~ 310

3600 RPM
4.7 ~ 320
5.7 ~ 375

I copied these numbers from what another guy posted in a forum. my driving is mostly around 1600 to 2000 rpms. at 2000 rpms the 4.7 has 50 more torque.

Twin Turbo's add power, but then there's more to fail. Will they be able to go 250k miles troublefree? Maybe...probably not for a lot of owners. We'll get a chance to look back after the I-6 has been out a while.
