I put a new exhaust on my 4.0 and really noticed that my engine overpowers my exhaust noise wise...like a whining noise...ive got 170,000 miles...is she just getting worn out or can I do something to quiet her down??

 

maybe it's an old belt... my exhaust definitely overpowers my engine noise.

 

its hard to hear anything over my exhaust. but i'm straight piped. 109k and still trucking. my hurst shifter made the tranny noise more noticeable.

 

im gonna get a new belt tomorrow...dont you have an exhaust video on youtube?

 

what year truck?

 

my 4.0 is pretty quiet. But im running just cats, but if its a whining noise you could have a loose vacuum connection or something like that.

 

Noisy how? Maybe your fan clutch is frozen.

 

My engine even with the new belt is pretty loud

 

haha yea man i do.. two videos of it actually. one before xcal3 and one after.

 

What you running for an exhaust?

 

i have close to 150 probably, the engine is real quiet except the faint tick.

 

Yeah, these engines get pretty noisey up in the rpms. Listen to this vid. The engine noise overpowers the exhaust and supercharger...

 

wouldn't you think the sucking of the intake causes the engine to be loud? BTW....freakin' love the fact that it's a supercharged ranger and it's a manual!!






my 01 4.0 is louder than my buddys 01 4.0. i'm not talking exhaust right now either....both idling in a parking lot, mine is noticeably louder running when standing in front of them.

 

Why did white smoke come out of your intake?

 

yeah but which run was that? your over 400hp? if i remember right that run was with Doug when you guys were messing with tunes. How much boost on that run? 8-9?

 

I think he has the snow performance kit which injects a water/meth mix to cool the intake. I think. I am sure he will chime in.

 

i got an 04 4.0 and the motor is real loud in the high rpms its louder then my exhaust but then again my exhaust is still stock

 

oh yeah, didn't think about that. thanks.

 

my motor is def louder than my exhaust at idle but once i get on it all i can hear is my exhaust. but then again i am straight piped

 

I'm just running cats and a y pipe...no muffler

 

I'll try to get a video after work

 

That white puff of smoke is nos. I`m not over 400hp, that was nicksters old set-up I believe. The closest I got was 360hp and 417tq. Kept pegging the maf (gt maf w/t ee kit) so Doug had to back it down to 333hp and 370tq. Plus, Doug would`nt let me leave the dyno making 360 on a stock motor. Something about leaving engine parts all the way up I-20 to SC.

 

well i was close!!

 

Sounds like it could be one of your engines accessories water pump, fan clutch, tensioner, idler pulley or alternator could be making noise. Pull your belt off and run the engine for a minute see if the noise goes away if it does it is one or maybe two of the accessories. Spin each one to see which is the culprit.

 

Ive been thinking about geting an electronic fan vs. stock belt driven fan. i heard this will quiet the enging nois consideraly exp. in high rpms. i have been interested in it for the hp and mpg gains.
