Thumbs up 2011 5.7 Mods & Subjective Performance Report

I have completed a plethora of street/drag mods recently and want to share my joy with those of you who might be interested. All mods are in my signature. I have no dyno results nor any track results yet and might have neither for some time to come (lately, there have been few opportunities for me to leave home, except briefly, because I am the care-giver for my bed-ridden wife who suffers advanced cancer). However, my 2011 RCSB 5.7 Hemi has spent some quality time in my home garage and neighborhood shops.

A mod I did not attempt was the the Circle-D 2800/3000 stall torque converter. A local transmission shop installed it and it was the most obvious single performance gain. It made the Ram "jump" from a standing start with truly satisfying authority. Otherwise, it drives in a civilized manner. Highly recommended!


As most of you know, there are no tuners for the 2011-up Rams yet so I had to be selective about mods that did not require ECU tuning. A 180 Jet T-stat keeps the engine plenty cool even in our recent 100+ weather although I don't know how far the temp might rise during a busy, daytime drag/track session.


I went with A Vararam Air Grabber with some reluctance because I was wary about power gains since there seems to be no empirical performance data available yet for the Air Grabber. The design made sense to me though. It installed easily and looks good. To compliment the intake, I also installed JBA headers (w/Dodge gaskets), Magnaflow Y-pipe, and Magnaflow 22" straight-through muffler/catback system w/o resonators. A computer reset completed the breathing mods and boy, oh boy, the intake and exhaust synergize supremely well. This exhaust setup is not loud until I go WOT, then the exhaust harmonizes with the Vararam to sing a lovely power song.






My local tranny shop also installed a set of OEM 4.10 gears and LSD without trauma or gear whine. I went to my tire shop for a McGaughy's 2/4 drop w/air lifts and to shed some tire/wheel weight and gain traction which came in the form of XD Addicts (17X9 front & 18X9 rear) for Toyo Proxes ST2's and Nitto NT555R drag radials. Both tires are almost 29" tall which gains some gearing advantage without being tiny. I think my stock 17" tires were 31.6". The speedo was easily calibrated for the smaller tires with a Hypertech Speedo/Gear Calibrator.




So, what does it all mean?

As mentioned in my title, my observations are subjective but...I am heavily stoked! I've been "hot rodding" for a very long time and am no longer easily impressed but this truck is absolutely transformed for the better in all respects with the exception of a slightly rougher ride (on stock shocks). With 36 psi in the drag radials for street use, the Nittos hook with the briefest squeal, the truck squats and boogies to 60 "right now" with a hard chirp on the shift to 2nd. Really scientific, huh? Also, the lowered center of gravity results in noticeably better handling through curves. Please forgive my occasional drool, it's involuntary. Can you tell I'm pleased?

I might install a 75-100 wet shot of giggle gas if I can figure out which colder plugs I can safely use in my `11. I'm working on the plug mystery and thinking about the sloppy-shifting transmission but, so far, these mods have combined to prove their worth. Honest injun. If it weren't so, I'd be bitching!

Seems like you have done all the right things to unleash the beast (short of a tune). Very informative write up and set of pics. Some reps for this .

So sorry to hear about your wife, I know how tough this can be. Best of luck in her care.

So did you get a 2800 or 3000 stall? Also everything looks amazing! Need to get a PCM swap for sure! Trq Management turned off, a long with 93 octane tune! you are probably loosing a bit of lower end trq with the headers and no tune :/ 350 dollars you can't go wrong!! This truck would be well into the 13s easy with all of this!

Looks like a real winner....when you get some free time can you post some side shots so I can see what it looks like with a 2/4 drop with 29" tires. Hopefully once I'm your age I'll still be into performance...pretty sweet man.

Thank you.

Chris, at Circle-D, verbally described it to me as a Dodge 11" HP-I, 2800 to 3000, as though it stalled "somewhere" between the two RPM. I am only certain of the way it performs, which is stellar.

Thanks. Yep, I'm getting old but the thrill of a hard launch remains undiminished. The following pic is the best I can do now:

Looking good! One thing I would recommend to compliment your drop is an Addco front sway bar. It much improves the corners and handling. Give them a call and let them know your vehicle model/year and they will get you set up! ADDCO 1-800-621-8916

I appreciate the tip. I'll check it out.

Nice write up and mod list. Does the new stall have any noticeable effects on mpg?

Thanks. I don't know because I don't track mileage.

Thanks for this post OP, your Mineral Grey Metallic Ram further inspires me to step up and start doing some performance upgrades on my Ram. Did you go with the McGaughey spindle kit or the 2/4 drop with new shocks?

Awesome looking truck again, and thanks again for all the pictures.
