little bit more power??

i have a 2011 ford ranger 4.0sohc was just wondering what would be the best way to add a bit more power?? thanks

Tuner works pretty well.

Cat-back exhaust, tuner like an XCal III, Zabteck throttle body.

IF!

If there was a simple way to add even a LITTLE more horsepower, doncha THINK Ford would have put THOSE parts in there instead of the ones you've got?

Lets say the exhaust, why would Ford have put a restrictive exhaust on there when a BETTER exhaust would have cost them the SAME amount of money?

Or the throttle body.. If a BIGGER one would make more horses, why didn't Ford put that same BIGGER one on there? It would cost them NOTHING!

Now the aftermarket has lots and lots of bright red and yellow parts to SELL you.. but all they do is to MAKE you feel better about your ride, and in most cases make more NOISE. In actual fact some or even MOST of those parts cause less milage and even SLOW the engine down.

That new Ranger is the last and best design of the Ranger line. It has all the goodies of previous Rangers and prolly a few new ones. The ONLY modification you might need or use would be a lower gear ratio if you add taller tires.

While I agree with you, the generic tune is best when the truck is a general use truck, I think that when you start getting specific goals that non Ford parts and tune may be beneficial. I haven't done enough research to be definite about what would work and why, but any time you want more of one thing you lose at the other end: eg. less higher top end performance is a trade off for more torque, more horse power generally means less gas mileage, etc. I'd say that you have to have specific goals in mind before you can figure out how to get "more power".

Yep!

You are right in the middle of it Richard! That may be the single best post on modifications in the whole forum.

To honestly get anymore power you really have to open up the engine and do some work, head, cam, intake, blah blah...

Not sure how Ford did it but the Mustang version of the 4.0 SOHC makes 240 hp, so there's more power in there somewhere.....

I don't know, but im guessing a different cam profile... The Mustang doesn't need low down torque like a Ranger does...

just remember air/fuel/exhaust...
with more air (filter change) you need more fuel, and with more air and fuel you need better exhaust.

you can't change just one and have the right ratio of the 3...
a tuner would be your best bet. and gears if you want larger tires..

 

[Big Jim M]

Well.. sort of..

just remember air/fuel/exhaust...
with more air (filter change) you need more fuel, and with more air and fuel you need better exhaust.

you can't change just one and have the right ratio of the 3...
a tuner would be your best bet. and gears if you want larger tires..

IF a filter change would actually allow MORE air (and hence more fuel) into the chamber... The engine would ping and clatter from too much compression!! (there can be NO arguement to this fact!!)
The result of this would be the computer would attempt to STOP the pinging.. which would result in retarded timing.. and even a richer mixture. So the NET result of MORE AIR would be worse performance.. Got that? Worse performance!
So all these ads for K&N and such are simply LIES!

However you are correct.. If it were possible to get more air you would then NEED more exhaust.. More exhaust without that "more air" is also a waste and MIGHT make the ride run worse.

Without changing the camshaft ANY modifications to the intake, heads, valve train or exhaust will result in zackly the same performance or perhaps WORSE.

im not sure if i agree with the k&n comment, what proof are you basing this info off of if you open the intake up ( CAI) and put a high-rate-of-flow muffler that would increase power by cutting back on back preasure there for cutting back on the exhaust gas that is left over in the cylider after it fires, ford engineers build for performance=life of vehicle=part simplicity=parts cost ford wants power, but the upgrades available do get you 1-20 hp but bolt on performance parts will not get you the same increase the cam, heads and an intake manifold will but in newer fuel injected rangers that are computer controlled can be tuned by pluging it in to a prgrammer or your comp with some software of course but the idea is tuning . . . timing advances will get you more power ask any top fuel dragster if you dis agree with that your ful of sh** but its going to cost you in the long run -more power=harder on drivetrain=shorter part(ie trannie engine) life -but to say that a K&n does nothing and might actually decrease power is a farce k&n has spent many years under the hoods of many dif makes and models its not just more air but the velocity of the air entering the cyliders that in turn will increase power if anything it cuts back on mechanical friction making easier for the piston to drag more air into the cylinder ie more power and as for the more power comment im pretty sure you guys knew what he ment, so please stop baggin on this guy he just had a question anwser it or dont say anything at all i feel liike yall might of jumped the gun a little on this one i have K&N cold air flowmaster delta and thats it i have gain 15 hp 10ft\lbs dyno proven thank you for you time i love my ranger and i love this site so lets be helpful and not degrading oh yes there are many marvels mysteries oils power adders that will your right big jim do absolutly nothing the best thing you can do is educate yourself on how a motor works and go from there once again thank you for your time hope i helped alittle

oh and that throttle body why plastic if anyone has an anwser i would love it the only thing i can come up with is the rate of expantion when heat is intruduced

Don't want to be an ass... But, I'm calling BULL, and a whole bucket of it... NO, a K&N system crap will not do anything (on a stock engine) except let more dirt into your engine...Now, if you had P&P'ed the head and swapped to a more aggressive cam profile, I could say a K&N MIGHT do something... Why? Because then you are actually pulling in more air than you were before... Adding a filter system to a stock vehicle does nada... You are not adding any air anywhere (which is what is needed to create horsepower)... You claim the K&N will flow more than the stock air filter assembly? OK? Big whoop... I'm sure it does, but just adding it to your truck doesn't mean your engine is going to magically start sucking in more air... It seems like you need to learn how an engine works... Imagine the engine as just a big air pump... The more air you get into the engine the more power you can make... BUT, and this is a big BUT, the engine can only suck in what is possible due to combustion chamber size, valve events, and speed of the motor... Just putting on a different filter isn't going to change that... I promise I'm 90% positive the Mustang gets more power by having a longer duration, higher lift, more aggressive cam profile, which increases horsepower, but moves that power up into the power band, with less low end torque... That is what he is really asking for anyway... People don't want more power, they want more TORQUE... Making alot of power makes a car hard to drive... Making alot of torque doesn't... If you really want more power open up your engine mill your heads, raise your CR up to about 10/10.5ish, throw in a more aggressive profile cam, new exhaust (header back), port and polish your heads and intake manifold, underdrive pulleys, A/C delete, open up the bottom end and throw in some better rod bolts, raise the rev limiter a good bit... It will be annoying to drive on the street (you won't have any power or torque until 2500/3500 rpm), you'd need to gear it like 4.56/4.88 to use that power...

To the OP if you seriously need more power regear your rear end to 3.73... That's about perfect for our trucks...

Throttle body spacer? Also does nothing...
