Just installed today. It's honestly just for the sound. I enjoy it for now, but X amount of miles later, I might change it back. Who knows. It's giggly fun for sure, but at least it's a 10 minute install and removal so, no worries if you ever change your mind.

This thread has been great entertainment, so thank you all.

I'm all about making these trucks as wild or as tame as you want. Mod away, OP!

Ps Im about to order an exhaust and BOV next week. Life's short, mod shit.

I've been running the Go Fast Bits DV VTA - nice blow off sounds! Loudest I've heard so far....

Polar Bear: Just for the record, the Lima L4 is a 140.4 CI, or just over an exact 2.3 Liter. The 2.3 in the Ranger, is just under 140 CI. More significantly, the L/R ratio is different, hence the somewhat higher peak torque in the newer version.

I know there are guys pushing the new L4 upwards of 400 HP on E85 on the stock block and head. The Lima L4, using a big valve head and roller cam, can do about 500 HP on pump gas, using a dead-stock block and crank. Add in a dual OHC Volvo head, and you can add another 125 HP.

Just goes to show you, Ford can build a decent, high power, 4-holer!

To the OP...BOVs or BPVs (bypass valves) functionally serve only one purpose:. To relieve pressurized air from the intake tract between the turbo outlet and the engine intake when the path into the engine (throttle body plate, etc..) is closed. Keeps all that pressurized air from slamming against the compressor blades of the turbo, slowing it down and in some cases, stopping it (compressor surge). This is more helpful when driving a vehicle with a manual gearbox (on off accelerator because shifting), less useful when operating one with an automatic gearbox. As long as that pressurized air isn't metered, meaning accounted for by the ECM, there's nothing wrong with venting to the outside world. If you happen to like the sound of a duck quack, squirrel fart, whistle, that sound your favorite stripper makes when he/she tries to hide a fart in public, whatever.....I'm sure there's a company that will satisfy your desires and being that many people seem to get painful vaginal irritation over someone else's personal choices these days, you'll manage to offend someone regardless of which product you choose. Good luck!

I took mine off today after driving a few weeks on it, the gf didn't like how much louder and the way the gears changed was a lot less smooth, as if you could feel the gears changing now with more rigid-ness or "roughness"? How come it made my intake/exhaust louder, I think mostly on the intake side. I have no engineering experience so I was wondering how this could occur. I am sort of sad now that my car is smoother and not as loud. At this point, its not so much the hiss, but the loss effects of the BOV on my intake/exhaust decibels that I am grumpy about ahaha. I also lost throttle response as well. After I took it off today and went for a long drive with the gf, she instantly agreed it was so much smoother and a lot less quiet not including the hiss. Same driving habits, drove same way I did with BOV, let it spool up and then let go, just the gear changing is buttery smooth now, downshifting and upshifting. The gf is happy, I am not happy. But she agreed to let me use it when I want to show off around town :crackup:

P.S I know I may sound stupid complaining about my ride becoming smooth. I have weird likes and wants..

I had Boomba BOV's on my previous 2 Focus ST's and they sounded cool on that car.....not so much on a pick up. IMO
The JDM in me can’t deny it. I never had a nice car before this, just a modded Mazda 3. And a Chevy Colorado.

I installed the Dual Port Turbosmart on mine, I like that it's not obnoxious unless you're deliberately trying to make it obnoxious. I suppose I'm spoiling an eventual build thread I'm gonna do here, but I've got it and the Borla exhaust.

First trip out I was waiting at curbside pickup at meijer and 2 kids walked out of the store, I'd say like 6-8 year olds, so I gave it a big old rev and let the exhaust and the BOV sing the songs of my people, and they both stopped dead in their tracks, turned around, one yelled "SWWWWEEEEET" and the other yelled "DO IT AGAIN! DO IT AGAIN!"

That made it all worth it.
