Ford Mustang 2.3L EcoBoost – 18 PSI Boost Peak w/ Twin Scroll Turbocharger!

The 2.3-liter runs 18 psi of boost (not that you’d know it)

Where the center dash vent would be on a six- or eight-cylinder, the turbo four’s cockpit embeds a pair of blue-over-black dial gauges. Closest to the driver is oil pressure; next over is a boost gauge. We noted a max of 18 psi (a smidge over 1.2 bar) indicated during the test runs; it appeared to taper towards 15 psi at redline.

Torque felt adequate and spool was quick, though we were expecting a little more pep in its step. The soundtrack is in the same spirit as the Focus ST, though with a bit more grunt and sans induction noise—save one section of full-tilt lift into heavy braking, there wasn’t much sneezing and whirling from the 2015 Mustang’s twin-scroll snail.

Still, they seem to be fudging on the peak HP & torque numbers.  I’ve seen 315 – 330 HP and relatively the same in peak torque.  And no, it’s not the same engine as the Lincoln MKC (tune and supporting parts will be totally different).

Shift Knobs

If you’ve an STI or WRX, I’m sure you’ve either looked at or purchased aftermarket shift knobs (or even purchased SPT versions).

Here are a few that appear to be worthwhile to own.

I’ve a very heavy Razo knob that I used in my Eagle Talon awhile back, but the threads are different between the cars, so I can’t use it in the STI.  I might find a new one and mount it in my car, though.

The cool thing about Delrin is that it won’t get hot or cold like metallic knobs typically do (but I tend to like metallic knobs better).

There’s also Flossy knobs, but I will not link them.  Flossy shift knobs are highly desired, but I wouldn’t order one directly from the vendor, because customer service sucks to the point that you might not ever get your knob (it’s a crap shoot).  If you want a Flossy, I recommend you check for For Sale ads on Craigslist or your favorite Subaru forum F/S threads.  Order directly at your own risk.

Do you have a favorite shift knob?  If so, share the maker/model!
