    Boost vs CFM

    CFM is the determinant of horsepower. The airflow in pounds per hour determines how much fuel in pounds per hour the air can burn. Air flow determines fuel flow and the fuel flow determines the engine's power output. Simple as that. "Boost", on the other hand, is a measure of inefficiency...

    Which Degree?

    I think it's worth thinking about because it'll put you in an interesting position. People who matter will look at you not as a tech guru, but a skilled and experienced practitioner in whatever field you're in now who actually understands how data and security work in that field. These days...

    Which Degree?

    This is a field with a spectacular shortage of people: https://asuonline.asu.edu/online-degree-programs/graduate/computer-science-cybersecurity-mcs/ Yes, it's a Masters, but if you do the IT Bachelor's, it should come next.

    Total bridge collapse in Baltimore...

    I'd be surprised if the IBS on a ship built in 2015 didn't have it's ECDIS managing the rudder to enable track following. Big fuel savings at stake. However, all that goes out the window when there's no engine power to turn the propeller or hydraulics to swing the rudder. Track following...

    Total bridge collapse in Baltimore...

    This is the same picture with the vessel speed turned on: The "legend" at the bottom of the AIS web page shows the green speed at around 10 knots and the red speed at about 2 knots, so it was slowing down. Using the "measure distance" function on the webpage, the distance from the course...

    AMG = $$$$$$

    Interesting - so what's with the steel reinforcing on the block side of the main bearings? I'd think that if they need it on the top, it'd be on the lower cradle as well.

    AMG = $$$$$$

    The whole situation is a mess. It looks like, as @black99lightnin said, that the block and crank are actually from an AMG GT Black engine, not a C63 engine. That could explain the engine failure caused by the mismatched lower bearing cradle. The cradle probably is from a C63 cross-plane crank...

    Credit card application process

    There was a period in my life where I was a high-profile target for identity theft and it happened three times. Twice, one of my online accounts was compromised and charges were made on my stored credit card, and once someone stole a new card enroute to me by mail and used it to successfully...

    MM CC plates interference

    I don't have experience with the 1990's Mustangs - got my first one in 2011 - but I've used various combinations of camber plates, camber bolts and slotted lower strut mounts on every one of them ever since. My GT350 is the first one that didn't need a lot of camber engineering to be stable on...

    Ats/Taurus calipers install and brake bleeding help

    One suggestion - before you start unhooking things, crack one of the bleeders and push the brake pedal about half-way down and block it there with a stick or something. I use a piece of wood against the front of the driver's seat. What this does is block the connection between the brake fluid...

    Anyone connect their grill to their home natural gas?

    I did this swap on my Weber back in 2010 or so. Best idea ever - no more cylinders that go flat at the worst possible moment. All you have to do is buy a NG valve manifold and NG burners from a spare parts supplier and bolt them in. I don't recall the parts being expensive but that was a...

    2018 Voodoo or Godzilla for a swap?

    Have you read any posts or stories about putting a 10R80 on a Voodoo? The flat plane crank engine tends to build torque and HP above about 3k RPM. I describe the driving experience as "it feels like you're driving a Honda until you hit 3K". With a manual gearbox, you just drive it, but it...

    Wheel fitment on GT350

    Mustang GT rims won't clear the front brakes without a spacer - a big one. Some can work at the rear. In the winter I run OEM 2014 GT500 rims (9.5x19) on my GT350 with a 35mm spacer up front and straight bolt-on at the rear. Front offset is 30mm and rear is 62mm. Front tire (295/35) is the...

    Best Brake Bleeder Kits? Motive Products vs MityVac

    A few notes on doing bleeds with these tools - I've been using them on and off for 20 years: 1. Use a turkey baster or some other kind of picker-upper to lower the level in the master cylinder reservoir before you start. I drop mine down as far as I dare, fill it up with fresh fluid and drop...

    Ford Mustang GT3 Testing | Ford Performance

    Someone on this forum, a few months back, provided a surprisingly confident and clear post describing a genuine second generation Voodoo FPC engine with somewhere between 550 and 600 HP. Now, the video above makes it clear that Ford sees the Mustang GT3 race car as a promotional item to sell...

    F-16 Sonic Boom Scramble

    Pilots fly the altitude and the airway they're cleared to fly by ATC. They can't change either without approval from ATC - too big a risk of collision. The autopilot doesn't have any hands, so it can't operate the radio...

    F-16 Sonic Boom Scramble

    Presumably it was one of those horrible situations where a high-flying business jet develops a cabin leak at high altitude while on autopilot. Lack of oxygen puts everyone to sleep and the plane just flies on until it runs out of fuel. Payne Stewart died in that type of crash back in 1999...
