Pathetic low end torque

Im considering it, but it seems really loud. Is that with the windows down? Is there ANY drone at cruising speed?

 

Wow this thread is still going....carry on.

 

There is just the absolute tiniest hint of drone at plus highway speeds, at 70 when cruising I'd say it's just barely audible with wind noise but certainly not louder than normal wind noise. It's very quiet comparatively. And yes the driving video is with all four windows all the way down for effect, and the other video I literally redlined it with that second rev from about five feet away so it should be loud as all hell without rear cats, but to me that's surprisingly tame. I had the urd y pipe before and it was EASILY twice maybe three times as loud

 

So the Y pipe with stock exhaust was louder than the U spec system?

 

...I give up. I was just kidding! Ha ha ha. I'm going back to work now.

 

Not quite, I had a mbrp turn down before as well. I sold the stock exhaust and then sold the y pipe and the turn down to cop the spec u and "no ragrets" for sure lol.
That all being said, the y pipe seems like it's just louder in general than the spec U. I'm not sure how to explain this in all layman's terms but basically they use a machine that analyzes and determines resonant frequencies that the engine makes and that's how they build the spec U. Similarly to how if you hold a nice guitar some notes seem to ring out really loud? Engines work the same way with certain noises too, and it turns out you can tune an exhaust's thickness, as well as pipe diameter in order to make the exhaust and engine resonate in harmony, rather than working against each other. The effect is less vibration throughout rpm range, smoother flow through exhaust, more power, and a much cleaner sound without a whole lot of distortion. Much the same way that certain woods are selected for an instrument to enhance the sound of those resonant frequencies. It's a highly technical process that URD goes through to create this pipe, and as a happy customer I can say the expense of the pipe is well worth it if you, like me, love spending time in your truck and like listening to nice exhaust noises

 

I'm probably going to get it, for the sole fact that I got the OV tune coming in and I would like to have 330ish crank HP!

 

What do you guys expect when the V6 is the same basic platform as a Camry? The 4.0 with all of it's flaws was an engine designed to be a truck engine. You all realize this thread will shit down soon because it's subject is somewhat unflattering to Toyota Corporate. I have been banned for posts less inflammatory than this.

 

Right there with you brotha chasing every last hp this baby's got. One thing you might want to consider is swapping out all the fluids for low drag fluids. I used Ford motor craft MT fluid, redline diff and tranny case fluid, and Schaeffer's engine oil. Schaeffer's engine oil alone would be a HUGE upgrade over Toyota world shitbox oil.

 

Shao Kahn's "Where are they now?"

On the internet reviewing 3rd gen V6, apparently.

 

You are welcome

 

The engine is way downtuned for MPGs. It's simple.

 

This^^ and I don't get where people think this engine isn't suited well to it's application. Engines have come a long way since the old days where truck motors had to be torque monsters to get things moving. Sure this engine has to be revved out to make power, but it's got a damn forged crank and conrods from the factory!! It's built to handle abuse more so than lots of other engines, and tuned to last longer as well. That means there's going to be plenty of potential there when it comes time to get this baby tuned right, because the motor can handle the abuse and will be happy to spit out a lot more power as well. Look it up, virtually the same engine is used in the Lexus is350 and that makes 30 more hp at over a THOUSAND RPMS HIGHER!!! And that's still conservatively tuned. Toyota initially tested the motor to over 8500 revs

Accurately describes this thread.

 

It's one thing squeeze more HP out of an engine with the same displacement. Another to get more torque at low RPM without forced induction.

 

Typically I'd agree, but results are results. I drive the truck every day, and it's a 6 speed. You can feel when an engine doesn't have to work as hard to do the same thing, and that's the best way I can describe the truck after the URD spec u install and other upgrades I've done. It just seems more efficient which allows the engine to work as best it can. At the end of the day, everyone is entitled to their opinion. Some of us just choose to support their opinions with science, research, and logical methods.

 

It has nothing to do with the subject dude. Flattering or unflattering, fat or skinny, powerful or weak, bad or good. It has EVERYTHING to do with the words you type. You get banned? You said something wrong. A thread gets shut down? It's because A) There are hundreds more exactly like it or B) People like you post crap that inflames or incites. BTW, do you have a 3rd gen? Just asking.

 

Of course it is. Why? Because that's what the majority of the Tacoma owners WANT! People want efficiency, that's the driver nowadays. And for the majority of Tacoma owners, the current power level is quite sufficient. The truck does not NEED more power, it does just fine. A small percentage of people like you just WANT more power, and you justify your thinking by claiming in multiple threads "it's underpowered" and expecting other people to concur. I have no problem with the fringe wanting more power. It's been that way since the first automobile was produced. I hope that you get more power with whatever you do. For the life of me though, I cannot figure out why people like you (more power) bought this truck to begin with? Why not buy a Tundra or a Ford or GM or Dodge full size? They have a lot of power. Why not simply trade for one of those trucks instead of trying to change this truck?

 

It's the government. And I like my Tacoma.

 

I speak for nobody else when I saw I chose the Tacoma specifically because it's a midsize, meets the 4000cc engine requirement for the Baja 1000 7sx class, and also handles great and already has a reputation as being a very reliable truck. Now since then, I have strengthened all of the mounting points for the suspension in the front and rear, added skid plates and eventually bumpers which add weight, and also added a traction bar as mainly an insurance policy on the driveshaft but also for that extra grip in takeoff. Obviously my case is a little different then average being that I'm building a purpose built race truck that is built well enough to still be street able at the same time and that doesn't describe everybody's build, but are you gonna tell me I don't know what I'm talking about still knowing all that? And with that being said, if you knew a few tricks that could add a few more hp then why not? Sure the Tacoma doesn't come as a race truck, but that doesn't mean it has no potential. Just as easily as people can say just stay stock or buy a raptor, I can say I like the looks of the Tacoma and it's size because it's easier to control 4500 lbs than a 6000 lb full size no matter how you slice it.
