Increase horsepower??

I was trying to find a post on here about increasing my horse power for my 2004 Toyota Tacoma 4x4. The motor is a v6. Curious about cold air intakes? Tuners? Or the cheapest vs expensively upgraded. Would love to hear what ya done or know.

 

Only way you are going to get any increase in HP is to add in a supercharger. CAI will not increase HP and just a tuner on an NA engine won't make any real difference.

 

Like stayed above Magnuson supercharger is the only way really or a custom turbo. You could do headers, exhaust, cai, ect. and gain 5 to 15hp at most and would need a tune to take advantage. At that point your halfway to buying a supercharger anyways. What does suck is the SC on it's own only adds 40ish hp. If you add underdrive pulley, fuel, and tuning you can get 70 to 100hp increase. With all supporting mods like the bolt ons with the supercharger you might get lucky and make 300whp.

 

If you want relianble hp, buy a different truck. If you just want to tinker, buy bolt ons.

 

Supercharge it!

 

Is it safe to bolt on a supercharger with OP mileage? Asking for a friend.

 

Do you feel lucky ??

Like anything else it all depends on how hard the skinny pedal is romped on.

we all know the temptation is there

 

Where is the mileage in question?

But in the end, it'll come down to more than just mileage anyhow

 

150 and change

 

NOX!

 

So, she's just broken in lol.

Unless it's puking blue smoke, I'd go for it

 

No blue smoke. Mostly easy highway miles. All maintenance done at dealer intervals.

 

Cold air intakes do shit for HP. All they do is look bling under the hood and make more racket. I myself did the elbow mod and although the infamous "Gadget" claimed up to a 5HP increase, all it did for me was change some around-town throttle characteristic. I mainly did it to put the cold air intake point where I felt it should've been originally.
You have a want for more power. Go and get that supercharger and get 'er done. Nothing else to say. That's the one.

 

Supercharger is really the only way to get real horse power that is an easy bolt on solution.
A few mods and you can push 300hp and will feel like a completely different truck.

 

Dyno variances and "up to 5hp" ain't much I bet and could easily be missed.
I am however on the "stock intake is cold air intake" in the second gen sector as I've already measured a few based on ambient vs iat. So don't get me wrong, I am not a cold air intake fan.

 

The up to numbers are for marketing. Theres no other reason. From a pure logical standpoint, 0, is included in that up to amount. So is .0000000000000000001. As long as it's not a negative, they're not lying. Now let's look at logic a bit more.

When, exactly, assuming you get 5hp, does that 5hp happen? Is it idle? What a waste of fuel. Is it at your normal driving rpm? no, it's at peak. That means for .01 of a second, you have an extra 5hp. Then you shift and it's gone. Nobody really DRIVES at peak. And really what does 5hp at peak gain you? If you're driving a 80lb 5hp go-cart, holy crap is that extra 5hp noticeable.

In a 3000lb truck.... about the same really amazing performance boost you would see if you took a really healthy dump right before getting in the truck. Getting rid of weight is more efficient than adding hp.

When it comes to performance and bolt ons, save your $100 and spend it on gas. You will get the same performance but be 2-3 tanks further down the road.

Forced induction is a whole other thing. It works, it's not cheap.

 

like stated in the above posts... you will be wasting your time and money. There are improvements that can be made but at a large $ investment and you wont really get what you are looking for... useable HP/torque. If you look at the charts that the seller of the speed equipment shows most of HP/torque increases are at rpm's where you dont drive. A set of TRD headers arent cheap and you get maybe 5hp and then you have to install them... most 3.4's this is a real bitch. Then when you do install them even if they are Toyota you might start to get odd o2 sensor codes.

 

Cold Air intakes aren't even "cold air" intakes since they are just taking air from INSIDE the engine compartment. My K&N has a "heat shield" but the idea that it actually shields the intake from engine heat is laughable.

Mine CAI certainly louder, which from my finely tuned and calibrated butt dyno, adds at least 50hp.

The only "true" cold air intakes are snorkels or an intercooler. Any by itself, those don't really "add" any measurable horsepower.

As others have said, the only real option for a measurable increase in power is a supercharger. They do need to be tunes however, so make sure you get the 7th injector and all that stuff, too.

 

I think the stock air intake is a cooler air intake than what most CAI's are...at least the stock one pulls air from outside the engine compartment (inside the fender/wheel well). I've never understood how CAI's can make the claim that they pull in cooler air, except for the URD one that they sell for 2nd gens...since it pulls air from behind the grill.

A snorkel is the only true CAI in my book

 

Exactly.

I think they are more efficient in that they pull in a straighter flow path of air, but I'm not sure where they get the "cold" part, lol...
