I'm very happy with my Challenger, and am satisfied with it's power output, even at stock. I do wonder thought if the 6.1 is that much more powerful and fun than the 5.7? Anyone whose driven both with some input?

Thanks

I went from a 5.7 Automatic to a 6.1 manual and I'm not sure if it's the difference from going from an auto to a manual or a 5.7 toa 6.1 or both.. But I noticed a huge difference in power, torque etc.

There's a huge difference in Gas Mileage.

I have them both, 5.7 in a mopar 10 6 spd and a 6.1 srt 6 spd and there is a little noticable difference, but as far as i am concerned for the money difference the 5.7 is a better buy.Your just not getting as much car. :thumbsup:

People say there is I just dont buy it, I think the 5.7 has more low end torque cause of the VCT and the 6.1 has better mid to top end power, I have very minimal mods and my car put out for what I feel is decent power and torque, however I am sure past 60-80mph the extra displacement of the 6.1 would let it pull away. I feel if the 5.7 would have came with the srt exhaust manifolds and exhaust plus its air box and tube, the most you would see 15-20rwhp difference and the torque would be the same. Track times are running close to the same. The 6.1 would be a cheaper engine to mod, plenty of ported heads and cams to chose from, its just you personal preference on which car you want. To Mauls Im sure the 6 speed feels faster, but I bet the auto 5.7 would run with you. I have heard alot of people say that, like driving 6 speed r/t and an auto r/t or same with the srt. The sticks tend to feel faster, but for some reason the autos are faster in actuallity. I guess its cause your more connected with the manuals you feel faster. It used to be a stick would kick a autos ass, dang new fangled cars.

I've driven both, purchased a 6.1 with six speed.

I'd say it's noticeably stronger but nothing that blows you away.

I do like how the 6.1 responds to a cam, exhaust, and even mild head/intake work. Definitely wakes up a whole lot.

You get a lot more than just the 6.1; much better suspension, brakes, and etc. There's a lot to it. If you can swing it, get the 6.1.

The R/T is simply a great, great car though- you'll enjoy the heck out of that also.

I did a 5.7 to 6.1 swap. There is a difference mainly seen/felt in the 1/8th to 1/4mi as the 6.1 begins to pull away. Brakes, suspension, and forged wheels are the plus side to the 6.1 and even the 6.4.

If you want an eye opening experience, drive the 5.7 then go drive the 392.

The following attached PDF file shows the torque results of a Dyno day we had last year at RSP Motorsports.The R/T 5.7 Auto(Yellow line) with just a Mopar CAI and MBRP exhaust mods pulled more torque than an SRT 6.1 manual(Black line) with exhaust resonator delete.There was also another R/T Auto(Red line) with more extensive mods that pulled more torque.

Aslo,notice how much more torque & RWHP the Auto R/T(Yellow line) with just Mopar CAI & MBRP exhaust pulled over my stock Auto R/T(Green line) which was 100% stock at the time.

I thought there was very impressive gains for such modest bolt on modifications,...interesting indeed.

Also,I can tell that since installing a K&N CAI,JBA shorty headers(those stock 5.7L exhaust manifolds are heavy and the design is extremely restrictive in comparison to the JBA headers or SRT 6.1L clamshell headers),CORSA Xtreme cat-back exhaust and Predator Custom Tune the car has a big insrease in RWHP.I will be getting the car CMR Custom Dyno Tuned by the same facility.I fully expect to have gained at least 45 RWHP since the 100% stock dyno pull,...it sure feels like it on the 'Butt' dyno.

09 R/T Pony pretty well laid it out with the dyno sheets. I jumped from a 5.7 to a 392 and the difference is very noticable. The 5.7 is an extremely good engine with the VVT. Examining some of the older threads here will reveal that it doesn't take more than bolt-on mods to rival the HP and Torque of the 6.1.

There is a huge difference, however, in handling. The SRT brakes and suspension really do set the two cars apart. For a couple of years now, the question has been whether the price of an SRT is worth it when the 5.7 is so good. That, of course, depends on your preferences for power and performance.

The 392 removes all doubt. You will spend about $50k to move up to the 392, but the designers heard what the owners were saying and put our recommendations for power, performance and handling into the 392's. I love everything this car has, and I'm happy I traded up even though I thought the R/T was a great car with lots of power.

Well here is my take.

The 6.1 has a small increase in displacement and comes tuned from the factory to run on premium. It also has a better breathing ex manifolds.

The 2009 and up 5.7 Eagle comes detuned essentially to run on 87 octane, only needs to have a Premium Fuel Diablo CMR tune, 6.1 ex manifilds or other header type, a CAI and you are with 7 hp or so of the 6.1. With a fat power band :thumbsup: Now that totals up to 1800.00 or so with labor.

So my car cost 30k and with the above mods that comes to 32k lets say. and now you can run right along side of a Stock 6.1.

FYI,
Marion

The 6.1 has more potential in terms of Hp gains on the 5.7 and 6.4 at this point in time. If you had gone from a 5.7 to 6.4 you may indeed feel a big difference.

I just got my Mopar 10 with 5.7 and auto, and I love it, but...planning on getting an SRT 392 as soon as they come with the 8 speed Torqueflite!

I have gone over this in my mind a thousand times when making my decision. There is a small difference in the butt dyno department having driven both. The brakes and suspension on SRT-8 are where the more noticable difference lies. The brakes being Brembo provide a lot of stopping power for such a big car and do not have the spongy feel of the standard R/T brakes. There is also a lot less body roll, and the car feels more balanced and planted in the turns than a standard R/T. The SRT does ride harder though. That is why I opted for the R/T Classic with 6 speed and the Super Track Pack option. I believe the Super Track pack brings the handling pretty darn close to that or the SRT and really tightens the car up. I wish the magazines had tested a R/T Classic with STP to see how far off it is on the skidpad to that of the SRT. It would be on par I think if the car sat as low as the SRT. The upgraded brakes also feel in between the standard R/T's and SRT 8's. For around 7k less than the SRT, I think it is the best of both worlds really. The R/T with STP is not far off a SRT and with a few bolt ons, will actually be a tick faster. The SRT obviously starts out as a better car, but the R/T can be modded to outperform it. Depends on how much money you want to spend. I still really want a SRT deep down but now would not buy the 2008-2010 other than for color availability. The 2011 392 is improved enough to warrant buying it over the current SRT and R/T. I can wait for the 2011-20xx 392 to be discounted like the current 2010s are. When that happens, I may upgrade.

I to traded from a 2010 r/t 6spd (14 months and 14,000 miles to a 2010 srt 6spd. I can not say I feel any big difference at normal operating speeds in the engines. The 6.1 can be a bit more touchy in regards to fuel consumption but drive either hard and you are quickly approaching single digits. The best mpg hwy I had on the R/T was 25mpg and the SRT is 24 mpg (Trips over 150 miles). You can push the 6.1 a little further RPM wise and by seat of the pants (not very scientific) I think the power band is broader in the 6.1 at higher rpm. What I like about the SRT is the brakes and the "tighter" handling the car has (my R/T did not have the super track pack).

Do a search for my thread:

"SRT boys were right"

Whoever "doesn't buy it" that there's a BIG DIFFERENCE is in denial.. Sorry but I am one who owned an R/T for 1.5 years before moving up to a SRT. I'm not bashing R/T buyers. That's not my style, but drive an SRT for a while and make the determination for yourself.

Big difference...I say no

Now the 392 is a whole different story....Thats what the 6.1 should have been to erase all doubt

maybe your rt was a slug?

ive driven both and didnt notice much difference not around town. maybe at the track the top end is bigger but off the line, theres only so much torque you can push before the tires break loose

Hell with the engine debate....Patchs you really have 3 of those monsters in your garage?!!? that is beautiful...any pictures of that line-up?

ON the 5.7 vs. 6.1.....i went with the 6.1 6 speed just based on preference. Seems to be a fair share that have made the move from R/T to SRT but i haven't seen anybody go the opposite direction. So based on some of the prices on used SRT's out there i would look at direction if funding allows. but either is a good move!
