“... 442 under its expansive hood”

Ha! Similarly, when I was in high school we used to get drunk on the family homestead and see how far into the woods we could get my Grand Am! More often than not, we’d hang it up on a log so bad that the next day we’d need to drag it out with the tractor... which is hard when you’re hung over! God my friends were…

Well played

Yeah, if that’s what they mean... well then, this car website better hire some actual car guys to write their articles!

Hydraulic tappets/lifters/followers are always heavier than their mechanically adjusted counterparts, which is why they disappeared in every other serious form of racing decades ago. To control that lifter mass, you need a ton of valve spring if you plan on spinning the motor at race car RPMs. I mean, they must have…

Well... your logic certainly holds.

Every year I ask myself “Am I the only human that ever pushed a car out of a ditch without a tow truck?”

“with a solid lifter camshaft to eliminate the extra weight of a hydraulic system”

Every 1st gen Civic deserves an external header.

Well, when I worked for the government we had a significant slow-down in activity after every election. Many programs that were non-essential were paused until confirmation of continued funding at the exact previous level were confirmed. No department head or branch chief will risk her/his annual budget (which affects…

The US anti-ballistic missile program is not top secret, very public: https://www.mda.mil/

I think it was primarily studio driven. For example, GM built GMAL (their full-scale wind tunnel) in the late 70s and had every opportunity to develop rounder shapes there without being hampered by primitive CFD capability. Before that, everyone used Lockheed’s big tunnel in Georgia and the University of Maryland’s…

YOU MADE ME UNFORGET

Well, the text book that I started with was an edition of the Anderson text (https://www.amazon.com/Fundamentals-Aerodynamics-John-Anderson-Jr/dp/0073398101), though there are many that would likely do just as good a job. John Anderson is a pretty big deal in the aero community and is well respected. Pretty sure he…

The studio guys think round in the back looks cool.

It’s all dependent on the vehicle. Take the latest crop of mid-sized sedans. The Fusion/200/Malibu all have pretty low Cd (under .300), but they probably never gave a damn about the lift performance. These cars are optimized for cruising along at 75 with the windows up in 75 degree weather.

Your last paragraph really speaks to me. Most people don’t understand how their mods affect aero. For sure, it’s kind of an obscure science and I certainly don’t hold that against non-aerodynamicists. Hell, I buy tires because they look cool, they fit the rim, or they’re cheap and I’m sure there are vehicle…

Buy stock in ZF and LKQ first. Cool cars, but mechanically... well, they’re junk.
