I'm not sure what a "bonus standard" is... but I know that engineers provide design solutions that meet requirements, cost and schedule.Lol I’m sure they are more concerned with meeting that “ bonus “ standard but I really could be wrong.
Always run 89, so knocking shouldn't be a problem as with 87. I suspect you are right about the load management, we had serious issues getting it to not drop gears.
None of the breather mods I've read about report any gains ... everyone details the sounds but nothing about felt gains, dyno gains or better ET at track.
Because the engine is just a fancy air pump, air in and air out with the most efficiency is the key to better performance. On my '05 Duramax, I changed the intake to cold air, and the exhaust to duels with larger diameter from the down tube back. Also used a super chip tuner. Saw better MPG on the lower tunes, and scary gains on the performance tunes. Just waiting until the 5th gen has been out for a while longer to see what all the changes will be, and what real gains they make.
Right. Best gains are to be had with a tune to adjust a/f ratio... cam timing can help too...
The hole in the fender is plugged with a rectangular piece of plastic. I have the Borla exhaust and 0 drone with the ram air cai.
Thanks for the write up. Losing low end torque is a net loss for the people who tow...Well I'm not sure if I've added any value with this review or if I'm going to add to the confusion (maybe that's a conclusion in and of itself since there are no definitive results) but here we go. For those of you who don't want to read my incoherent review, here's the summary: 1) Sound? Awesome, lot of fun 2) MPG? I can conclusively say you should expect between 0-1+mpg gains. Why the range? read below. 3) Dyno? Literally no idea but I will say it's something between 7-15hp. Why the ambiguity? read below.
Sound
From another post:
“The sound is great, the video above gives you a solid listen to the different scenarios but I'll include an outside and inside video with db readings below. Here are my experiences so far: 1) It's a loud exhaust (believe Porboy or someone said if you don't want sound, stay stock). Cold start will feel like you're waking neighbors, get on it and everyone in the vicinity will know you're moving...however, in the cab it's surprisingly "refined." My wife, who hated this truck when I got it and will look for any excuse to mock it, has not complained riding around, she even was defending the sound/volume when I was worried about my early mornings and the neighbors. At radio volume 6, you can hear the exhaust riding around in the cab, at 8 it mostly disappears into the background and you're not sure if it’s a bass line or the exhaust, at 10 its completely gone at normal cruise and even stop/go around town. I have not found any examples of drone and I suspect you won't with the Mopar one since that is probably their biggest concern with an "aftermarket" system under the Mopar name. However, as someone stated above, sound is subjective and maybe someone else will be like "all I hear is this thing in the cab!" or something along those lines.
Lastly, I have not towed with it yet so I'd lean on someone else if anyone plans to do that often. I might be worried about loudness in the cab towing something long distance because if you're stuck at 2500 RPMs for an hour, you'll hear it, but I have zero experience.
Overall, I love it. It makes it so much more fun to drive. I am still worried about the neighbors when I leave at 4am but no one has complained yet so I guess I have that going for me.
Recording (Done on an iphone XS using Decibel X software and not meant to be accurate as to actual DBs but merely show difference before and after)
Before Recording 12/16/19
Outside: 80.0 Max (55 degrees, 44% humidity, mic centered 5ft from exhaust at 4ft from ground)
Inside: 68.2 Max (0-50mph, medium acceleration, no radio or fan speed, windows up)
After Recording 12/21/19
Outside: 97.0 max (52 degrees, 43% humidity, mic centered 5ft from exhaust 4ft from ground)
Inside: 74.2 max (0-50mph, medium acceleration, no radio or fan speed, windows up)
The outside numbers are slightly misleading so I will caveat them here. The max DB is the initial bark of the engine starting. It's loud like I said previously, but it immediately drops lower and then settles at ~70 for the stock, and ~82 for the after.”
MPG
See my original post above about my travel habits so you can get a sense of city/highway combo. Here is where my unscientific nature has come back to haunt me a bit. I truly tried to limit a lot of variables and keep this as straightforward as possible but even with that, I think there were still too many variables simply because there’s no way these results are 100% attributable to the mods. Here’s the other factors I think could be attributed to the gains: 1) I had my first oil change at same time of install 2) As I said previously car passed the 2k miles mark and seemed to be breaking in a bit more. Having said that, I am 100% happy with ~1mpg+ gain in efficiency no matter what it is attributable to, so I am going to say it's the intake and don't you dare go ruining my hopes and dreams.
Before
Tank 1: 12.3mpg (Hand) and 12.9mpg (Dash) after 31.2 gallons
Tank 2: 12.2mpg (Hand) and 13.0 (Dash) after 27.0 gallons
Tank 3: 13.9 (Hand) and 14.1 (Dash) after 22.3 gallons**
**This last tank was higher because I had two highway trips of ~80-100 miles round trip each but I included it anyways.
After
Tank 1: 13.0 (Hand) and 13.7 (Dash) after 29.7 gallons
Tank 2: 13.5 (Hand) and 14.0 (Dash) after 25.6 gallons
Tank 3: 13.8 dash as I pulled into dyno shop
As for driving habits and if those changed, I honestly would say to everyone that I turned off the Fuel Efficiency screen throughout this whole test and tried to be normal with driving (maybe even slightly worse in the “after” test because the sound is so great). I am happy to keep everyone updated if the gains stay or if they drop back down in the case that it was some bias in my driving.
DYNO!!!!
This is where everything goes a little bit up in smoke, especially when I wanted it to be the most scientific part, because detractors are going to say "see! basically nothing!", people who bought them are going to see potential gains and be happy, meanwhile the whole thing feels less conclusive given how hard it was for the "new" guy to get a clean pull. The dyno sheet I attached is going to show 9bps of gains. One of the pulls that was completely not clean showed 13hp gain. Many showed no gain as the speed/rev limiter was getting triggered. I think that given the whole experience we can conclusively say this system isn't giving you 25+hp gains, so if you're expecting/looking for that then you need a tune or go for something else. Can we say it adds between 7-15hp? I think so. Do we know if it takes away from low-end torque like the dyno sheet shows? Inconclusive given the torque charts look like they were drawn by my kid.
I apologize to everyone for this rambling review and not getting you a solid answer by the end. I talked to the same tech as the first time and thought he said he was going to be in the shop, but was nowhere to be found when I got there. It's enough of a pain to get there and back that I wasn't about to turn around and go another day, but maybe I should have. Anyways, that's my review, I'll keep the thing simply because of the sound and mpg I'm seeing and don't want to jinx it, plus it looks cool. As always, try to be nice to each other in the comments.
Hahaha that’s a fact! Nice choice of crayon colors!
The “manual” transmission will not lock gears and is extremely sensitive to downshifting. Pulling in 6th is impossible though I believe that’s the optimal gear. Even 4th continuously drops unless you feather the throttle correctly. Hence why a bad pulls throw that torque chart way off.
I think it looks real nice but its a bit much. Back in the early 2000s Camaro sold similar kit with much more engineering for $250 and it actually added a good deal of HP. I cannot see how this is any different.Mopar’s “Ram Airflow” Cold-Air Intake System For Ram 1500:
