Some dyno results for the naysayers.

So the only gain from the bolt on parts are in the top end. Not often you go there at all. It's low end that you want and even then it's tough to get with a Turbocharged engine.

I think other forums like for the mustang and focus ones are altering the electronic wastegate for less lag. The bottom end power is fairly irrelevant until boost and fuel/air gets pushed.

The limiting factor is going to be the single injector per cylinder. I believe there are 'higher flow' injectors available but have not heard anyone actually testing them or tuning with our specific engine. Very expensive high performance DI cars have extra port injection but how to run those (since the DI uses a mechanical cam driven pump making crazy amounts of pressure) - a dedicated pump and fuel line plus how to piggy back a computer to run it?

The electronic wastegate on my truck stays closed as soon as I hit the gas. Obviously it moves to control the boot level but… I was curious so we checked, BOV and wastegate both close asap to build boost.
the fuel system is indeed limited but there is a little left in it. Injectors, HPFP Bap orlow pressure fuel pump would all be needed to run enough of the right fuel to make bigger power numbers. The 24+ 2.3 has dual injection so that won’t be a problem with them but it is on our trucks. I have seen people add port injection to the factory DFI but it’s always complicated and glitchy. I think my bottom end power is huge compared to stock as well as other tuners, my top end power takes over as the torque tapers off giving me a very long power band with very little lag.

The afr gets corrected by the stock (any proper) tune. The ecu will always go to its target afr as long as it is able to. That’s what fuel trims do every day.

Yeah I am no fuel management guy, but by "correcting" the air/fuel does that mean the ECU is either pulling or add timing, decreasing or increasing peak HP respectfully? My hypothesis is that the Roush box on 93 is allowing more timing initially.

I never included a graph to show the stock intake on the truck with the tune so I don’t understand where you’re getting those figures from.

I mean, I have my own data from my own truck (FP tuned on stock box), as well as the numerous dynographs from tuned Rangers out there. You can find those figures pretty easily, I wasn't insinuating I got them from you.

"correcting" the afr means exactly that, adding fuel to achieve the desired afr... You can change timing to adjust the power level but that does not affect afr as it is not the same thing.

comparing another truck/tune/dyno is not going to mean it is relevant to anything because of the many factors that are at play. Just the weight of your tires alone can skew results + or - 20hp when compared to another truck with similar mods but different tires.

So what's the point of this thread?

Just a note for all on the dyno graphs that @Loweredon33s posted. The big numerical values of data jump in 100’s of HP on graph vs 25 or 50 as can be seen on other graphs out there. Each dot on the vertical axis is worth 7hp. While the 3 pulls on the first graph might look close together, when you zoom in the data is more easily deciphered.

So the turbo inlet pipe is adding 15-18whp to several parts of the curve vs intake and exhaust alone while also using the restrictive lower half of the factory airbox and air scoop. Peeps spend more than $400 for the same gain with an intake or exhaust, so that’s a good value for a bolt on if trying to go fast.

Thanks for posting Mike and look forward to your intake dyno comparison.

For you there is obviously no point and that’s fine.
For others this comparison of parts and tuning on a SINGLE vehicle for consistency in measurements this thread has many interesting points.

Thank you for pointing this out!!!! I try to explain it but it gets lost in the translation sometimes. This is the stuff that actually affects your driving experience way more than a huge peak number with nothing to make it useful. Thank you seriously.

You’re welcome, brother!

I'm interested in finding value in my parts (and you will find many others do too) so when you start a thread that shows the value is in tuning (and tires - according to you) then there isn't really anything interesting about comparing parts that eek out an extra ~10 hp here and there.

 

[Loweredon33s]

I'm literally having this same problem on FB about the same exact thing but on my truck instead of this one.

Like I said.... For you this is pointless and that is perfectly fine. why do you have an issue with what I'm saying though? I am not trying to sell you anything nor do I have any intentions to do so. All I am doing is providing solid information to those who care to see it. You are obviously too intelligent to be bothered with these petty gains so just leave us dummies alone.

 

[Vitis805]

I really don't. I contributed to the discussion and you shut it down with:

But earlier in the thread you mentioned you are going to be comparing these graphs with your own truck later...?

I'm just not sure what you want from people on this thread besides blind likes. I'll give you those, if you'd like.

Please show me where I said that

I DID mention that i will soon be using my truck to compare an assortment of intakes.... You know, a single vehicle as a control to conduct testing on? Very similar to the test I had presented in this thread, one truck, one dyno, multiple parts and their effects, but on my truck because it is more modified and should find limitations in the parts better.

Vitis805, this thread is pretty simple to understand, I don’t know why you’re so confused.
Loweredon33’s said some information about parts, posted some dynos and that’s it, you can read them and see what some parts do and what others don’t. Don’t over complicate this thread. He’s not asking for anything from the people in return.
