Velossa Tech Design Big Mouth for 2019+ Ranger

[Engmus]

Installed today. It has a clearance issue if you have the 4 bulb LED grille light kit.

It does fit but I might trim the led light bracket back...or I might not. Pictures attached

It was a PITA with the light bar but again. Doable.

Nice, hardly noticeable...I was wondering about removing the colored ring to clear the light.

would like to the see the air/fuel numbers with this thing. its got to be introducing a excalibrated lean cruise condition on the PCM to get 2 MPG

You would think so, right? That the ECM would richen the fuel ratio to make up for the air density? But it doesn't seem to.

I think the colored ring/flare of the intake is a critical design component.

Got mine installed. Visually on an XLT grill you can't really even see it. I was expecting it to swoop forward more and be closer to the grill. It was hard to squeeze the extension through the grill to tighten one of the bolts. A long 1/4" extension would have been better, but I don't have a long enough one on the size. we'll see how we do with mileage. I'm already getting close to 21 so I'm not expecting a huge gain but I'm hopeful for something extra and hopeful that the xlt grill doesn't hamper performance. (Yes, I'm aware how dirty the truck is)

This is the grill design I was most curious about functionally.

I looked at your thread and the mods. Your particular grill really compliments the VT although better gas mileage after the mods you've done might be elusive.

Your original scoop modxwas pretty well thought out - I wonder what benefits it provided? I'd guess whatever performance changes the Big Mouth provides might be harder to quantify for you unless you have some detailed data already.

I tuned very early on and have monitored the temps. I don't recall much change with my scoop mod. My biggest gain was switching to 91 from 87. I'm going to try on see if any difference is noticed by swithing to this. So far just this morning the air box temp reached ambient for a while which it usually stays a couple/few degrees higher. But I do have traffic and not that long of a drive. I can only hope my mileage goes up as it's still kind of disappointing considering I'm pretty light on the pedal even though I'm mod heavy.

I’ve found that the airbox getting heat soaked is the biggest issue with rising intake temps. I’m building an insulated blanket for the air box for testing to solve heat soak hopefully.

It doesn't make that much of a difference once you pull some air through it when you take off.

I installed mine last night. I didn't realize it didn't directly connect the scoop to the air box. It collects the air an helps force it to the area of the air box snorkel. I'll post up the results after a tank of gas or 2.

Using the Procal 4 tool, the max low temp I can get after data logging for a month in city driving is 10 deg above ambient after the air box is heat soaked. Avg is 15-18 above ambient. It takes at least 15 min of 70mph driving to come back down to ambient; cool the plastic air box oven if you will. It doesn’t help that a tremendous amount of radiator fan airflow hits the engine facing side of the air box, continuously warming the plastic. I used to subscribe to the residence time theory that the intake air doesn’t move slow enough to heat up due to air box heat soak, but the data from the IAT sensor debunks that. A heat soaked air box after parking can raise air temps to 130-140 when restarting and insulating the box can help mitigate the issue so as to not need highway speeds for many minutes to get back down to coolest air intake temps possible for max power. I’ll post updates as I gather data post air box blanket install.

What you're seeing in part the hot air being recirculating from the bypass valve working it's way to the air box. It doesn't take me anywhere near 15 mins of driving at 70 to lower the air box temp for me.

I have a non recirculating setup right now so that’s not a factor. Plus the recirculation port is downstream from the IAT sensor, and under throttle is not recirculating due to the nature of auto trans vehicles and the subsequent throttle plate not closing under steady throttle which opens the DV / BOV. What tool are you using to monitor IATs as maybe my Procal tool is off?
