Performance out of the 10-13 5.7 hemi?

[2wagons1driveway]

What have you all done besides tuners- intakes- and cat back exhaust?

Any luck with camshafts or superchargers or long tubes?

If so any issues with any of those fore mentioned?

What about throttle bodies?

Wouldn't mind some more jam out of mine...

I have heard the 6.4 cam was a good swap for the 5.7. Guess a lot of the car guys were doing this in their Chargers. Haven't tried it and after the nightmare tuning debacle of trying to put a supercharger on our JK, I never will.

Whipple supercharger.

All depends on how deep your pockets are, lol. You can make power, but getting your trans to live with power and the weight of our trucks will be the trick. I cammed my PW and I don't regret it one bit, but you have to decide what you want to do and can live with. Best advice I can give you is find a good tuner and start with a simple custom tune for your truck and go from there. For tuners I've tried Hemifever (so, so results), White Lightening (actually got my truck to run how it should), but I'm looking for a new tuner and I'm really considering giving Jay Greene a shot. He is a pretty solid tuner and if you are looking for cam recommendations he knows his stuff and can probably point you in the right direction. Remember you need to build for torque on these trucks, and don't get hung up on peak HP/TQ numbers. More important to have a broad band not just high.

Torque monster, not a dyno queen

I think you and I may be in a similar boat Lee, you need more power, but you need it up higher in the rpm band than most fellas would find desirable. 5.13's get you off the line quick but you're running out of steam at speed right? Cam and long tubes are what you're looking for. Good for another 50+ horse at the wheels. We have the same engine, mine needs to have more jam at 3500+ rpm, low end is fine. With the gears I can light up 37 toyo mts and do donuts in front of the police station no problem lol. Sometimes you need to be able to steer with the throttle at speed right?

There's a shop in Calgary that has been doing Whipple kits on 5.7's. They're getting 600hp at the wheels with custom tuning (also done in Calgary).

There are these: http://www.edelbrock.com/automotive/mc/ ... hemi.shtml

Not cheap though.

I really just want to put a diesel in my 12’. Now it probably won’t happen but I’d like to dream about it for a few years lol that 6.7 with a small tune is a beast compared to our gentle natured hemis

Well that would be silly


Sure they make oodles more power. But you would be way better off just buying a cummins truck to start with.

Btw where the hell have you been?!!??!

Diesel??? Heh...funny... goin' for a brodozer?

If you're gonna do an engine swap: 6.4 Hemi SRT > Viper V10 > 426 Hellephant.

The biggest gripe I have with my 5.7L is the lack of passing gear on a 2 lane highway. I know that a 3/4 truck will never be a rocket, but the passing gear sure isn’t very impressive in these tanks. I’m really hoping the next gen HD Power Wagon’s get a significant bump in power!

[FordyceCreekTrail]

At 410HP with the 6.4 I think its less about HP, although meeting or beating the Raptors 450 would be good, its about cutting weight. Use the new engine blocks, aluminum body's, high strength steels, synthetic winch line, ect to make way for sliders, 35s and better power to weight ratio. And hit better fuel mileage. Inquiring minds certainly want to know. They certainly have not leaked much info.

My trucks at the dealer having five recalls done and they gave me 2019 1500 loaner. The 8 speed transmission is such an improvement.

This thing is rocket. The 8 speed transmission is the ticket. The older rams need 5.x diff gearing. Hell the newer 66/68RFE's too.

Yep I have a ‘17 half ton, and the drivability with the 8 speed is night and day better. The truck just feels like it is twice as powerful as my pw, and I consistently get 17-20 mpg with it. I wish my wagon drove like it.

It's half the truck

[Rodeoflyer]

It's not even in the same class as the powerwagon. You're absolutely right it's not even half the truck. But the 8speed is amazing.

However with the 20'' wheels I'm averaging 15.3 mpg with evo on. My wagon with 35's averages 12.5 with evo off. I've had the truck a few days now and the mpg isnt that far off.

But yes 'feels' twice as fast.

Drives like mom's minivan over boosted steering and brakes.

The new 1500's are so refined it's crazy. If I was blindfolded and someone told me I was in a body on frame vehicle I'd never believe it. They are amazing trucks.
