    "Mustang Mach E" Confirmed, Reservations Begin Immediately After Nov 17 Live-Streamed Reveal

    This. If you want a fast SUV, its name won't matter. If you don't want an SUV, its name isn't going to change that. Norm

    Help explaining horsepower and torque feel

    Ummm . . . peak HP happens when the torque being developed by the engine falls off faster than the rpms are rising. A CVT is a rather unique situation in that it can allow the engine to provide maximum acceleration potential at all road speeds. That's if the transmission programming dials back...

    Once you know how to calculate acceleration, you understand it better. Guaranteed. Norm

    Help explaining horsepower and torque feel

    Evidently. There's no getting around the fact that peak acceleration is only a momentary snapshot of what is going on. Using peak conditions to describe "feel" is a bit too simplistic. Then again, I've been running these acceleration sims for nearly as long as the Mustang has existed so I am...

    Any driving that doesn't need the coolers, doesn't need Streetable Track & Competition tires either. PSC2 tires represent short-lived overkill for touring given that the PS4S is more than capable of supporting that use. FWIW, I would put canyon running closer to touring than serious tracking...

    Help explaining horsepower and torque feel

    You missed my point entirely. (a) Max acceleration in any given gear is maximized with the engine running at peak torque rpm. (b) Max acceleration at any given speed is maximized by running the engine at peak HP rpm and gearing accordingly. It's just another case of gaining more from staying...

    Help explaining horsepower and torque feel

    Ideally, you upshift slightly past peak HP rpm, assuming that there's a few more rpm available. You're still losing less torque than the upshift to the next gear would cost you in terms of ratio. Norm

    From 370z to Mustang GT

    I would argue that your driving at that particular instant wasn't exactly in line with Ford's definition of "normal driving". Which doesn't necessarily mean that you made a mistake. More like you were briefly trying to color outside the lines. I would further point out that at such times your...

    Help explaining horsepower and torque feel

    True . . . but that's not the only truth here. Peak acceleration at any given road speed occurs when your combination of drive tire size, axle gearing, and transmission gear ratio puts the engine at the rpm where peak HP is developed. That's a useful chart. From it, I think you could take...

    Extended studs and slip-on spacers

    Obviously you'll be needing open-end lug nuts to secure the wheels. But if there's enough exposed thread to double-nut the stud, without there being an absolutely huge amount of exposed thread, you could take the OE closed-end lug nuts and run them down to cover the threads. Torque to maybe 30...

    Show off your daily driver when your Mustang is in winter storage.

    The Mustang never goes into "winter storage". It just gets used less, or acquires a mod project that keeps it off the road for a while. Here's what gets used more. Being retired, if the snow is too deep for it, we don't bother going out. The car in the background belongs to our daughter...

    Extended studs and slip-on spacers

    Winter driving really calls for the wheels to be set back a little deeper into the wheelwells. There's more stuff on the roads in the winter for the tires to throw off, so you might as well aim that stuff further away from your car's paint. Function > appearance here, lest the future...

    Unless MIchelin has done something different in the carcass of the 325, a 305 would have less sidewall flex than a 325. That's part of why mildly stretched tire and wheel combinations work better than pinched combinations. I'm not surprised about the wear pattern being good. Easy to spend...

    I'll have to track those hardcopy and online articles down, I'm sure I've got the print copy of R&T around here somewhere. The title (What happens when you let engineers tinker) rings a faint bell . . . I have to admit that the apparent boundaries of "honing the ultimate street Mustang" seem...

    2% is a good correction factor, but I'm pretty sure it works the other way in this case. The speedometer of a car perfectly calibrated for 305/30-19's will read lower than actual when fitted with 325/30-19's. IOW, 200 on the speedometer would be 204 on the cop's radar gun. The real bottom...

    Proper Camber and Toe after installing lowering springs and spacers

    Sportlines are typically among the springs with the greatest drop. I'd plan on using camber plates. You may also want at least a bumpsteer correction kit, although that can more easily done later as a separate mod if need be. Norm

    I don't doubt it. Too bad Ford didn't consider endurance under still harder driving more seriously. I can't believe they were unaware of people driving stockish Mustangs at HPDE at least semi-seriously Norm

    The PP2's lack of powertrain component cooling suggests that they aimed it to compete with the 1LE's image rather than that car's substance. Norm
