More Horse Power?

No stock N/A 4cyl 300+Hp. There is a guy on YouTube with a 500hp N/A civic but that’s built to the absolute teeth lol!

But I do agree 100% there is no company pushing out even close to 300hp stock N/A 4cyl. That would be completely unreliable and they would go bankrupt trying to warranty it! Lol also not everyone has access to e85.

 

Ford's "ecoboost" is mostly a gimick. You can't cheat physics; the amount of power an engine generates depends on how much fuel is burned and how efficiently that kentic energy is transfered to the mechanical energy. Most modern engines have the efficiency part down. The extra complexity of a turbo enigne is not worth it. Besides, smaller engines with "V8 power" are generally burning more fuel because they have to run extra rich to maintain combustion chambers temperatures. That extra "rich" fuel is not burned but passess out the exhaust and is waisted. The only benefit is you have less mass to accelerate, possibly giving better city averages. But for the most part, the "MPG's" advertised with "ecoboost" will only be observed if you drive around with a very light foot as to not spool the turbo; basically a 4 banger (or 6) with a very restrictive exhaust driving a big heavy truck. This is why user observed MPG's are no where near the EPA's ratings. A properly sized engine is always the best option.


OP, you want power? You can do two things:

Advance ignition timing and run high octane gas for a small gain.

Or add much air and fuel into your engine; turbo charge, super charge, or NOS, for a large gain.

A V8 would generally give you more power more efficiently.


I recomend, re-gearing if you want better acceleration.


Just for those that are gushing over the Ford Ranger:

Get a V6.

 

V8 gives power, safer. I’ll question that turbos aren’t worth it, but I’ll agree that they’re implemented wrong here. Our EPA regulations have hampered them and they can’t run as efficiently as they do across the pond (they have multiport injection over there while we’re getting carbon building DITs).

Wouldn’t the fuel / blow by gases you’re talking about also be taken care of by EGR valves (which are deleted by people using vehicle-specific dyno tunes, not OTS tunes)?

Agree with the turbo - MPG sentiment. Trucks are significantly heavier and moving different payloads. You have to build boost to get the advertised power, and if you’re weighted down at all, bye bye economy. That’s the only reason they’re economical in hot hatches and sedans they’re all engine with minimal drivetrain loss.

Thumbs up on gears. It’s safer imo, and safer isn’t always cheapest. Either that or a V8 swap

 

I'm not a big fan of turbos. I had one on my 2014 F150. I liked the power but the spooling of the turbo I did not like. I also had a customer Fiat w/ a turbo that went, so not too big a fan of turbo and not sure how reliable those are as the miles stack on

 

I believe Ford is running multiport since the first gen ecoboost.

EGR valves just recirculate exhaust back into your intake to minimize combustion at low temps (which releases harmfull gases due to inefficient burning, or something like that). EGR tends to lower MPG's IIRC and I don'k think modern engines need to use them anymore but I could be wrong.

Engine efficiency is the same for a light car or heavy truck but yes, for heavy vehicle, a greater load will be put on the engine to accelerate translating to more boost and less efficiency. The reason a smaller engine is prefered IMHO is its lighter and smaller which helps maximize opportune weight distribution of your car which isnt a big factor for anything other than race cars. Generally you want your (race) engine positioned behind your fron axels which is easy to do with a 4 cylinder.

 

Yea the S2000 was what I was thinking was the biggest factory NA 4 cylinder production engine. There probably are race engine out there that are fully built that have more power. But as far as a regular production engine I don’t know if any 4 cyl that’s 275+. They all need turbos. The old saying there’s not replacement for displacement old true when you’re talking about naturally aspirated engines.

Only way you’re getting big power gains would be with some type of forced injection, or a shot of nitrous. While OV tune may be getting there on his Turbo kit, there still isn’t anything that’s readily available for purchase.

 

Does the F150 in a REAL WORLD APPLICATION really get better mileage? My friends 2016 3.5 Ecoboost doesn't even come close to the lab controlled EPA mileage stated. We take his truck on our annual fishing trip from Utah to Montana each year we're lucky if he gets 14 MPG. I know because I pay for my share of gas and wonder how such a small engine can swallow that much gas on all highway miles without towing anything. And all 4 of us aren't really that fat.

 

On http://fuelly.com the 2.7 eco boost is about on par with the Tacoma but its hard to compare. The F-150 is also running an aluminum body; you need to compare curb weight to better understand how the Ecoboost and Tacoma 3.5L MPG's are comparable.

 

I had the original understanding that EGR Valves raised MPGs, managed intake temps, and burned leftover fuel that snuck by on the first cycle (which thereby also contributes to carbon buildup..). EPA thing, like rev hang (again, from what I’ve read many moons ago). I know my last two turbos had them (‘10 GTI, ‘15 WRX), and any real tune called for them to be deleted (which required a tune anyways because it would throw a code immediately).

Either way, no replacement for displacement. I’m still waiting to see that 7.3L Ford that’s going to replace the V6 EcoBoost in the Raptor.

 

Had a buddy that owned a 2.7 and raves about power and economy. He also never hauled, drove like a grandma, and drove somewhere nearly completely flat at sea level.

 

this is basically how almost every attempted performance or handling conversation goes around here. not all, but most. because "it's a truck" or some stupid bullshit like that. feet are for walking, so don't ever run, right?

 

Around this time with my old ecoboost I was averaging 15.5-16.5 with my f150. My Tacoma is around 14.5-16. A lot of that is from the remote start. I also used my remote start in my f150 a lot more because I hate how the Tacoma shuts off when I open the door. I changed jobs so now I’m driving longer trips. My average is around 17.8 in the summer. My f159 was around 16.8 and probably would of gotten better mileage driving this same route now. On trips to PA to visit family the f159 wouldnget around 18-18.5. My Tacoma will get around 18.5-19.5.

When I worked at a ford dealership I would see guys coming in with the 3.5 ecoboot with 20 mpg averages. I’m a little heavy on the pedal. These were also on the 09-14 body style trucks. The new ones get a little better mileage because they weight a few hundred lbs less due to the aluminum. I’ve seen 2.7 eco boosts getting mid 20’s with a crewcab. Pretty impressive.

Give that the f150 is a bigger truck and weights more, yes I’m a little disappointed in the fuel economy of my Tacoma.

 

No the EGR valve helps with NOx emissions. Its just to add heat into a cold ignition when your engine is running cold. More modern EGR systems close the EGR valve at a certain operating temperature IIRC.

The EGR shouldn't affect the tune but I could be mistaken. If the ECU is compensating fuel delivery due to the exhaust gasses I can see but I dont see why the ECU would do that. The exhaust gasses should be neutral and not affect the AFR's but again I'm not sure. I am sure the ECU is managing the EGR and will throw a code if it doesnt work (or is removed).

Now one issue with large displacement engines vs small displacement engines is pump loss at low engine load. The amount of air being pulled by the large cylinders requires the TB to be almost closed to keep fuel delivery low when engine load is light (highway speeds is generally the issue). This causes very ineffient burn also because there is not enough air in the cylinder for proper compression. The compression creates heat which helps efficient combustion. However, most modern engines have cylider deactivation or are designed to run lean. That said, I will concede that a smaller ecoboost engine should have a small advantage here.

 

Nope. F150 was stock. I put a set of Wildpeaks on my Tacoma. Most of my driving in my f150 was back and forth to work 5mi each way. Then I would drive a company car around to the different dealerships I was working at. So I wasn’t on the highway much. I also drive 5-10 over the limit. And with the f150 because I loved hearing it blow off I would get on that thing a bit. Miss that truck and the power.

At our ford store I would see them with ranges all over. Most crew cabs seemed to average around 17-17.5 with the 3.5

 

I'm a Chevy guy that just switched over to Yota with my '19 SR DCSB 4x4. My first real truck was a '96 OBS with a 350 V8 that cranked out around 230HP. My recently traded Chevy was an '04 5.3 V8 that was around 280HP. My point, is that I was happy with both vehicles power wise and to have a V6 throwing up numbers that match v8s of recent years and still be reliable is something that shouldn't be frowned upon. I will say that I put a Diablo Tuner on my '04 to help with that loooong first gear that Chevy has, but damn was it a night and day difference on that truck. Anyone wanting more out of their trucks I'd recommend going to the tune route. I'm new to Tacoma game, but that OV tune looks like the only game in town and legit as well.

 

I'm returning the goldfish I bought. The damn thing can't climb trees as well as my cat. My point being you shouldn't expect things from a truck that it wasn't designed for. You step on the gas and it gets you from A to B just fine. If you want a kick in the pants or you have too much money and need to shred tires regularly, trade it for a Challenger with a Hemi. If you want to tow a 40' travel trailer, get a Tundra. If you want a nimble, trail crawling beast, get a Tacoma. No car/truck made does everything well.

 

Or just get a turbo

 

what do you mean vaporware? like folklore? haha

2nd gen being the 4L...

 

I see the interest and ‘it’s coming’ chatter peak every now and then. Then someone comes back with ‘I just talked with them and they don’t have any firm plans yet’. I’m not holding out for it if that means anything.
