I raced a 03 4.0 edge the other night and beat him by 2 cars.... Everyone that owns a 4.0 seems to talk about how much faster it is than the 3.0 which isnt exacally true. Mines a 00 2wd single cab flex fuel. Air box mod, Kn drop in, MAF mod, Dynomax exhaust with no cats, Underdrive pullies, efan, Autolight double platinum plugs, Autolight professional series wires, Mobil 1 oil in the trans, engine, and rear end. Dunno bout other 3.0's but mine seems pretty fast to me. Can be going bout 10 mpg and still spin the tires by punching it. Raced a 3.0 edge stock and beat him by atleast 5.

 

great job

 

It sounds like you have a screamer there, but I don't know that those mods would be enough to beat a 4.0, at least not a SOHC......

 

Manual, modded 3.0 vs. 4.0 SOHC auto? Maybe on a good day.

There's no replacement for displacement as they say.

Don't get too uppity -- a stock 4.0 SOHC with a manual will eat you up, supercab or not.

Your two weights were not close -- if you had the same transmissions, and both had supercabs -- forget about it.

The 3.0 is a good solid platform -- but it is by no means a racing motor and you're fooling yourself if you think so.

Now, if you're serious you can go over to http://www.rogue-performance.com and see about REAL 3.0 mods like cams, roller rockers, port and polish of manifolds and headers, etc. -- and you'll still have less HP than a 4.0 SOHC.

 

you might still have less hp but could develop more torque outta the OHV

 

That seems unlikely though -- you think you're going to get more torque out of a design which wastes more in the valve train and has lower displacement? We're talking v6 to v6 here, not i6 to v6...

 

i doubt it was your truck who beat the other truck.....the other guy just didn't know how to drive.......

like John said above, "there is NO replacement for displacement".....no chance in heck that a 4.0 got beat by your 3.0 unless the driver of the 4.0 didn't have a clue....

the 4.0 has almost 100 more stock horsepower than a 3.0.....and even a heavily modified 3.0 doesn't meet what a stock 4.0 puts out.....

 

racing rangers? i cant pass a ford taurus on the interstate in my 4.0, guess i was spoiled for having a 300whp srt4 for the last 2 years prior. 12 sec quarters and 17 second quarters are so far apart now

 

wait are we talking a 2000 and older 4.0... cuz them i would maybe believe it. But a SOHC 4.0... NEGATIVE GHOSTRIDER. If you threw on a whipplethen sure a 3.0 can run with a STOCK SOHC but im pulling out the bs flag otherwise

 

even with an OHV 4.0 it isn't possible.......the OHV has most of it's power at low end....the OHV would pull away from a 3.0 and then the 3.0 might catch up, but not pass it...

 

yeah i was just saying a bolt on modded Single cab 3.0 with a good driver may have a chance vs a stock OHV supercab with a "not so smart driver".

Mark, Not trying to flame you or anything but from my experience of racing quite a few people i just dont see it as possible(yes taking into account my larger tires, extended cab, etc etc). Go take a video and prove us all wrong!!

 

It was a 02 4.0 supercab auto trans. Dont see how u could not know how to drive a automatic lol. Just push it to the floor. Yea my little truck runs good wouldnt say its a race engine but its not slow. honestly none of the z71 and f150's in town can beat me. Ill have to get a video made sometime then. Nah i understand the 4.0 are quicker his must been running ****ty then. U gotta think though i weigh atleast 1000 pounds less than him. With hardly any gas my truck only weighs 3100 pounds with me in it. Friends v6 camero is heavier.

 

you don't weigh 1000# lighter......the cab on Rangers isn't heavy at all.......i picked up a corner of mine when i was doing my body lift........the engines have almost no difference in weights......

and you can NOT know how to drive an automatic....

 

about 4 months ago I "raced" a Ford GT...about as soon as he heard my exhuast start to roar he blew past me like I was going in reverse, lol.

but I did get what i was really looking for, a chance to hear his car in WOT...sounds amazing!

 

Pretty much the only way you can beat the 4.0's is with forced induction. Not saying you CAN'T do with with N/A engine.. but it would require a lot of internal work. Throw your truck on the dyno and it'll seem a lot less peppy. I had almost every bolt on, aside from an Efan. This includes.. UD pulley, headers, intake, exhaust, Xcal2, ROLLER ROCKERS.. and was disappointed by the numbers on the dyno. Then of course we bolted on the whipple and saw some real numbers. :)

 

im curious, what were the numbers before the whipple and after?

 

Bring it on....

3.0, 4.0 eh, really tired of the v-6, doesnt compare to a fullsize truck with a v-8 which i want badly. whether it be chevy or ford.

 

I had an F-150(2000) & my Ranger would smoke it even on its worst day.

This is before and after:
Modded N/A vs. Whipple (stock airbox)

Whipple w/ cone filter and a 73mm C&L meter:

Dyno.jpg?t=1175197183

On the first picture you can definitely tell which one is with the n/a composite upper intake. torque curve is flat as a pancake.

 

did the f-150 have the 4.2L engine? or the 4.6 or the 5.0 or what.

 

i raced a 2wd, 3.0, whipple, supercab ranger with a manual trans, with my 4.0 supercab 4wd, 31s and an automatic and still beat him. but every truck and driver is different.

mainly the majority of all 4.0s will beat the 3.0, but there are some rare 3.0 beasts out there.

 

red x's....

 

there we go

 

I used to have a 3.0 and now I have a 4.0. From my experiences with the two trucks there is no way in hell that my old truck could beat mine now. But it could happen, I don't doubt it at all. My truck with all the weight and s*!t I have put on it could still beat my old 3.0, but that is the only ones that I have drove so I don't know.
