3.0 no torque


nothing wrong with my truck had it in my shop all im asking is that will 1,7 rockers help me get some more power in the lower rpms or should i sell this turd ass 3.0 and drive my jeep
 
from what i heard 1.7 rockers will yield slight hp, not enough to notice a HUGE gain if i've read right. You have a 3.0, 3 liters make their power up in the rpms, lower rpms and its just gonna seem like a turd, my 3 liter with 4.56s and 33's will set you back in the seat in the 3k and up rpm range.

The roller rockers IMO are not going get you the results you want. You might as well put a for sale sign on it. If you really like the truck and want to keep it, as others have already said, you need to change the gearing to accomplish what you want it to do. Good luck, I hope you get it worked out like you want it!

How many damn times are you going to repeat yourself? I read this the first 3 times. Let it fawking rev!!! 3.0s aren't made to be driven like a V8. They're made to rev, your stock gears, 33" tires and your poor choice of which gears to use when driving is a large part of your problem. Stay out of 5th ALL the time, use 3rd on hills, or get 4.88s or STFU.
 
If it doesn't have the power to keep it going down the highway with 4.10's and 33's, then something is broken. You're chasing the wrong issue by throwing 'performance' parts at it. Fix what's broken first.

x2

your 04 makes 180 ft lbs just as my 06 does, i havent done much to it, and i light up my 31's all the time. and i have an auto.

with stock gears and 31's

55-60 mph is 2200rpm

80mph 3200rpm

100mph 4000ishrpm
 
why does every one have to be an ass hole all i want to know is if 1.7 rockers help move the power to lower rpms i dont want to spend a lot of money on gears for my ranger its pointless. im not about to drive in 4th gear everywhere and get 10mpg so i guess im going to sell this turd ass ranger and gfm because i dont know what i am doing apperently

Apparently.

Why is it that you think running in 4th gear will make you get 10mpg? The whole point that everyone else here is saying (and you've chosen to ignore) is that 5th is the WRONG gear with those tires and 4.10's under most conditions on the highway. 4th puts you where you need to be in the power band. You're the one choosing to ignore the FREE advice you ASKED for.

Your truck will cruise until the tank runs dry in 4th on the highway and get better fuel economy than you're getting in 5th, and have more power available at the same time. That you choose to convince yourself that you know better doesn't make you right.

Changing the rockers around (and pretty much every other engine modification except forced air) will let the engine rev higher. It doesn't increase the amount of airflow per cycle, which is what you're looking for. It would actually make the problem worse given you're reluctance to shift properly.

i dont want to keep this thing going, but if you really are getting 10 mpg in 4th it solidifies the fact that there is something wrong, bad rings maybe, idk.

to answer your question, will it make more "power" yes, in the low end like 1500rpm idk. how ever i would spend my money and time finding out why your only getting 10mpg.

i lost a rear tranny seal at 40k, should i have? prolly not, thats more or a 75-100k thing but i did. I just ask you to look at things that can be wrong, even if its not there "time". before you throw in the towel

are you dragging your breaks at all?, i had that issue for a while.
 
Hasn't the roller rocker question gotten answered a few times anyway?

This is getting repetitive....

its not letting it rev higher just with rocker ratio and it is does increase the amout of air per cycle by opening the valve more throughout the engine rpm range its not changing the profile of the cam. i want to know if anyone who has done this if it is worthwhile and driving around in fourth is 500 rpm difference i think your the one who is convincing yourself that you know better and your deffinetly not right you probably dont even work on your truck with the 1000s of posts you put up "expert"
 
I'll give you one thing in this whole thread - you are right in the last post about 1.7 rockers. I responded thinking about roller rockers.

I'm not sure what language you're speaking in most of your post.
 
I don't even understand why they make "performance" parts for a 3.0 V6 engine. I mean, it's a 4x4 truck with 33" tires for Christs sake, not a Ferrari. My low compression 3.0 turns my 31s with 3.73s no problem. I say re-gear the SOB.

well if you wanna know ill tell you in a few weeks im waiting on mine,

how ever, the only true hp mod i have done are the ud pullies, other then that we have the same platform, i do just fine with mine.

im not an expert by any means, considering we almost the same truck, i say something is wrong maybe a bad maf or something little. you say its all good and ill take your word on it. then it might be user error. shes a different motor then most. she likes to spin

also what is just fine for me, might not be for everyone, that be the case you might have to upgrade. but if its not broke......its not a pos its doing what it was designed to do. you just dont like what it was designed to, and thats ok
 
im pretty sure nothing is wrong with my truck i fix cars for a living all that i am asking is that would the 1.7 rockers help me a little bit with this problem i am having i can do 75 on the highway but when i get to a slight hill i have to down shift to forth and my foot is to the floor to try and maintain 75 or should i just sell this truck and drive my jeep

There is nothing wrong with your truck what you are describing
is completely normal for a 3.0 on 4.10's and 33's

Complaining about downshifting out of 5th?

I usually recommend for 3.0 2wd trucks running 27" tires.

Get a grip dude.

the 3.0 engine doesn't make peak torque until 3000rpm
and peak power until 5grand.

That is reality.
