Do mods really improve horsepower?

/thread

 

Only torque.

 

I’m sorry but there is zero chance your “s and b cold air” made any difference.

3G comes with a cold air stock just like all modern vehicles, and it uses same intake as 5.7L tundra. The 3.5L gets more air then it needs.

 

100%

Just hearing the intake noise will make you “feel” like you are going faster.

I do like the sounds of my poor man’s TRD intake but it added zero performance gains as expected.

I had a 2007 ranger and installed a k&n intake and I can say for certain that it improved performance slightly. I didn’t have to downshift as much going up hills. Stock intake on thr 4.0 was very tiny so that made sense. Tacoma uses same intake as 5.7L tundra sooo….

Actually adding a weld in magna flow muffler on my ranger, gave me an extra 25 or so more miles per tank. I was quite surprised. Had that muffler for a few years so it wasn’t just a “summer gas” or something.

On my Tacoma, borla S-type added zero performance and MPG gains. I do really enjoy the sound though.

 

The wife knows…

 

This^^

From what I've read these Atkinson style engines can (to a certain degree) decide how much air is even getting through the cylinder heads. The VVT system not only controls the advance/retard of the camshafts but also the amount of lift and duration of the valves themselves. The pcm can literally control the amount of compression driving down the road. If it wants to it can open things up, or throttle things down as it pleases

 

Yes, I now understand. It was some kind of placebo effect but also my gas mileage is also Improved from about 18 to 23. I rarely get 23 however, last weekend coming back from Silver Lake I achieved 23.

 

Lol

 

Yes, I need to do more research about this engine and learn All I can

 

I’m sorry but aftermarket Intwke would not gain you 5MPGs.

Tailwind, temps, humidity, summer/winter gas, driving conditions/style all play a factor.

As much as I would like to improve my MPGs ( they are not terrible at all BTW, I can still get advertised MPGs with my modded and lifted truck) The only way is to drive conservative and keep the truck as stock as possible.

 

The days of manufacturers leaving horsepower on the table are mostly behind us. These modern engines are for the most part extremely efficient right out of the box. Manufacturers are under immense pressure to squeeze every last mpg and efficiency out of these things as they can. Thin oil so the motor spins easier, tiny A/C compressors will less drag, electric power steering to get rid of the pump for example..

If there was an easy 10-15 hp available just by changing the intake design they would be doing it already.

 

Yes, that’s why I wanna stay away from large tires. I’ll drive 22 miles to and from work and we use the truck to go kayaking, camping, and travel quite a distance sometimes. I did put AT tires on it but stock size. However, it performed quite exceptional in the dunes last weekend!

 

Come on guys let the man have his magic air intake

 

One fact is for sure. It looks and sounds great!

 

Our cars don't have variable lift; only variable valve timing.

 

That bog right after the tire spin is killing you.
Try turning off VSC/Traction Control. Practice...practice...practice.
I bet you gain .2+ on a good hit.

As for mods.
The tune would be the only one worth the price.
Next would be a regear followed by a forced induction.

 

Don't look too much into that engine or you'll get buyers remorse

 

Also comes with a magic plastic coolant bypass pipe

 

I thought it was similar to a Multi-Air system like Fiat. But those intake valves are 100% electric I believe. That doesn't make sense for the 3.5
I'm probably wrong

I just read a bit more, the intake valves are just left open for a longer than normal period of time, so high compression is delayed until high rpms. Hence all the complaining about low end power I guess
