For All You Haters That Say Intakes & Exhausts Don't Make Power - Dyno Proof

Thank goodness others are seeing the BS. But again go ahead and spend the money and do this. Let me know how that butt dyno works. As many of you I have had many turbo charged 1.8 to 2.2 engines in various makes and an intake and exhaust are not giving you those gains.

 

nope, not me, aint going to do it.....

 

I think you are confusing some things. I don't see a broad issue with people denying quality tests that quantify differences. I do see some often inappropriate or missing the point criticism of some who will point out that modifications are often not cost-effective or have diminishing returns.

Maybe the 4 gen so improved in general has a new dynamic where fewer are even thinking of needing any modifications? At same time I can see how hobbyists want to.

 

I agree with OpeCity, more power/torque under the curve is better for the street than peak #s. You won't notice 11hp at wot and 5,000rpm but 30hp at 3,000rpm should be noticeable. That's the normal pull away from a light engine speed. With the same amount of pedal, you should feel more acceleration.

Questions I have are, their cat-back is 3". What is the stock exhaust diameter? I think it's also 3". R4T exhaust just looks like a tiny muffler.

I wonder if the TRD intake/exhaust, which doesn't add peak hp/tq, increases power under the curve. Believe some have said it feels like it has more power.

 

I think it will be crazy noticeable in towing or hauling uphill. 30hp more at 3000rpm would help me pull a steep pass with my camp trailer without even a downshift

that old NA v6 would be screaming at 5000rpm to do the same hill slower

 

I think the stock exhaust is 2.5, and I havn't seen a TRD exhaust but it probably keeps the big muffler and some or all of the resonators to keep it emission compliant. While their exhaust looks like its just 3" pipe into a short like 10" muffler. +120ftlbs at 3k, if true would be awesome and insane, you could definitely tell the difference.

 

I just blew the dust off my digital calipers & measured the tailpipe I removed, 2.5" confirmed.....
r4t exhaust is over-priced grossly from what I saw....
I get that its a quality piece, well though out, etc, but.....

Then theres this, 3" carven $590 vs 4ht 4" $1800....

I get pricing is in the details, stainless, fancy clamps, etc.....
Not for my wallet...

 

If I were shopping for a used vehicle and found it had a K&N, I'd walk away.

Well since you picked that scab...

Starting at about 2:30

Oil changes don't affect what gets introduced into the combustion chamber through the intake.

The whole video is nothing but misinformation.

 

It's not true. I'd imagine the real gains more closely mirror what you're seeing at 4K+ RPMs. Still solid gains though.

 

I laugh in solitude once in a while as well. That's what you were doing, because you can bet no one here cares about empty posts like you pretend laughing into the void. Go troll a Ford forum.

 

Business question.

If the products are $1600 retail, what would they have cost Toyota? $800 *maybe*, less the value of parts they did not install?

So how many people are willing to leave that much performance increase, with bolt ones no less, on the table for another $1k of MSRP on the truck? Even if it was part of an option package?

Maybe a few pencil necked bean counters who the development engineers can't get on the test track.

 

what you mean?

 

@spicy_fish_taco I'm curious too - especially from my 2 decades and about 250,000 miles of experience with my two earlier generation Toyotas. They were great vehicles but that experience made new generation stand out even more.

The new version jealousy is a strange one on my brain.

 

Exactly what I said. Do you have a more specific question?

 

So you are saying oil with 3k miles is just as bad as oil with 15k miles?

 

Toyota as a Tundra performance package that includes a CAI, cat back exhaust, and a tune. 32hp gain, same torque but 400rpm sooner. Cost $3,400. It was only for 2024MY Tundras. I think the engine issues slow rolled it's release. On the Tundra forum they talk about how that got just the TRD CAI (~$700) and an ECU tune from dealer for $160. Some also used the TRD exhaust, others a Borla exhaust. Using the TRD CAI without the tune resulted in CELs.

Assuming the 2.4L has a similar base tune as the 3.5L, you could expect a 23hp gain from a "factory" performance package. Toyota sells a lot more Tacomas than Tundras, you'd think they would offer a similar performance tune/package soon.

 

What?
You don't need an intake or exhaust to make that power.

We have local TW tuners making that on a STOCK truck.

Clearly I’m not saying anything remotely like that. You should go back and read post 49. The video in question is the one in the OP.

 

you said "Oil changes don't affect what gets introduced into the combustion chamber through the intake." what do you mean by that then?
