0-60 in 4 Seconds - My 2.7 Bronco Performance Modification Thread

[B22-2023]

It's possible, but this would be the first time I'm not seeing a performance benefit using E30. I would also think just adding the Injen CAI would give more than it has. When I'm halfway into the throttle she feels quick, but full throttle doesn't feel like it should. Wonder if I'm running into an issues somewhere else. I'm going to review MAP and IAT logs to see what I can find.

Also, because I have no patience, I did install the Racechip (Setting 3 out of 5) and It makes a difference. Nothing huge, but it's there. Didn't do any 0-60 runs and I took it back off, as I don't want to push my luck. I want the new plugs and IC installed before I go all out. The IC just got here yesterday, but still waiting on the plugs to ship.

That CVF will make a difference. Going back to temps, I haven’t attached my AfE hot and cold pipes yet to the CVF Intercooler but re-reading the specs they say the higher flow can bring engine temps down in addition to power so I’ve decided to move up that project.

No issues with IATs or boost. Three back to back full throttle runs at HWY speeds. IATs look good when on the HWY, but drift up to 110-115f when in stop and go traffic. It's in the 50's here, but in the summer I can only imagine how high they will get.

Also checked Coolant, Oil, and Trans temps and there all within range (under 200f)
More logging to do, but it appears everything is functioning well. Seeing close to +2 PSI of boost with the Ford performance tune. Hoping the Racechip on setting 5 gives me another 2-3 PSI. Going to be hard to measure that since it's a piggyback solution.

i know when i had my hemifever tune on my blown 5.7 grand cherokee and switched to lower than 93 gas and then back it would take almost a full tank to re-map. that was an old '12 and maybe things have changed now?

Y’all doing the lord’s work, cost benefit analysis going in my head constantly but pump 91 is my best at altitude so without octane boosters I’m still settling for sport mode and no warranty threats

Do you guys trust the hp/tq gain numbers that INJEN puts out? According to their website the gains are:

• Cold Air Intake - 26hp and 27lb.-ft. of torque
• Intercooler Pipes - 16hp and 17lb.-ft. of torque
• Performance Exhaust - 9hp and 10lb.-ft. of torque

Total possible increase of 51hp and 54lb.-ft. of torque.

These numbers are about 50-100% higher than what other companies claim such as AFE CAI (16hp and 27lb.-ft. of torque), and MISHIMOTO Intercooler Pipes + Intercooler combo (7hp and 10lb.-ft. of torque).

If these numbers are true, then with the Ford Tune, the 2.7L will be pushing around 406HP and 487lb.-ft. of torque.

 

[Fishwrinkle]

From my experience just a cai won’t bring anything worth mentioning to the table in terms of hp. Sure it breathes better but the motor can’t push that air out fast enough without modding everything that air goes in and out of.

 

[Gluestick]

Never trust claimed output or gains. I have never seen such real output.

Bolt on power gains are never additive, even if the claims were true, stacking them up will never achieve the total output you think of when mentioning the possible increase. This is sadly the reality of the aftermarket.

 

[MWILD]

Agreed. From my own testing I’m not really seeing any improvement in my 0-60 runs with the Injen CAI installed. Subjectively, I do feel a difference in the mid-range power when just driving around town, but can’t really measure that.

That being said, there are a few videos showing the K&N CAI adds around 15-16 HP on the dyno, so I imagine the Injen would be similar, perhaps slightly better.

some of this may be expectation management.

I’ve done the CVF downpipes into the Magnaflow catback exhaust, FP tune, TS valve. I don’t expect any more power from the valve, but expected some gains from the tune and the turbo-back exhaust. I’ve been pleased (though a lot noisier).

I havent yet invested in any of the major CAI functionality as I was hoping to see enough others with experiences to learn what’s really working well especially when off-roading since there’s some tradeoffs with filtration and water management.

But in the meantime, I threw on the big filter and window lid from Burger Tuning (a less expensive version of the Roush). I’d say “I’m very pleased for now” because my expectations were rock bottom low. I’m not feeling an overall power gain (and didn’t expect one) but I do experience a more responsive pedal. To me, that’s about all I would expect from most changes to intakes until you hit limits with what the turbo can pull in. We might smooth the curve some and get a bit more but it shouldn’t be much.

same with the intercooler and associated pipes: I plan to do this in the future, but I’m expecting more consistent power as it does better with heat management, rather than more power. I see that still as valuable from the perspective of dragging a loaded overland trailer and rig full of gear through the forest roads.

But for measurably more power, I don’t think we’ll see much unless we are increasing cylinder pressure with the combo of more air, fuel, spark timing and compression. So the chip, tune, spark, and fuel changes make the most sense to me. I figure the E30 change requires quite a bit for the computer to adjust to take advantage though, or use something like a JB4 with its selectable maps to tell it when you’re running the good juice.

or if the goal is the 0-60, maybe it’s better to focus on wheels/tires sizes and weight. Lord knows when we changed wheels to marchesini magnesium or BST carbon fiber on the track bikes, those things became rockets that turned better, held a line better, and it was like gaining both big HP and big brake upgrade.

From installing these mods, and also having an exhaust (Magna-Flow) I will say there is an improvement, but how much is a topic of discussion. With all performance mods, you need to take the said gains with a grain of salt.

This said the Injen system is one of the few systems that does go to the turbo and TOTALLY replaces the OEM setup. There is nothing left of the OEM system when it's done. Their system is also considerably larger in diameter and has less restrictions and bends. All of these things together help the system work better. How much better? Well, that needs to be determined.

I missed the opportunity to get a dyno run before I started adding pieces, but knowing what I have added will help when I do get my dyno done. I can always go from other stock baselines and see where I end up. Not the best way, as all engines are different, but it will be better than nothing.

The butt dyno knows there are gains, but it cannot produce official numbers.

I also thought about going the CVF DP route, but I'll probably wait until tuning and turbo upgrades open up. At this point I'm not expecting the IC to make a big difference, but going to log some IATs before and after to see. Should make a larger difference in the summer months. I don't expect charges pipes to add a whole lot, but I still plan on doing them in the future. I'll probably wait until CVF's version become available, as they'll be quite a bit cheaper than everything else on the market.

I may do lighter wheels at some point, but I'm going to focus on the bolt-ons first. I don't plan on removing skids and seats to lose the weight, as I want to see what I can do with a full weight vehicle. If I was trying to be the fastest in all the land, then I'd grab a 2-door Basesquatch That said, I do want to beat Palm beach Dynos' times, but do it on full weight. No doors, top, or spare removed.

Anyway, all the bolt-ons are really in preparation for when tuning opens up. Whether I go Livernois in the short term or just wait it out for ZFG; I'm not really sure at this point. The Ford ProCal and RaceChip are just short term solutions, but still having fun playing with them and sharing my data and experiences with everyone on the forum.

Playing around with the Dragy video record option this morning after an oil change. Ran a 5.7 with 93 in the tank. Not my best, but wanted to try out this new spot that’s closer to my house.

 

[ChrisH]

I appreciate all your responses. I knew it sounded too good to be true.

Another question I got is what is the point of disconnecting the negative battery terminal? It was said a few times in this thread.

 

[Foxbody Barra]

Put it in 4 high, not 4a unless you hate your transfer case.
