On the movie "Senna"...

Go see it.

Whether you're a fan or not, you'll enjoy it (and if you're not a fan now, you will be). I walked out of that movie speechless with a big lump in my throat; all I could say to those that went with me was, "I need a beer". Hair up on the neck during the Brazil GP win, heart pounding when they splashed "Imola 1994" on the screen, head in hands when "it" happened.

Go see it.

On "Microsquirting" the Porsche 914

Bosch D-Jetronic The Bosch D-Jetronic system is pretty cool, especially when you consider it was designed in the 1960s. "Computer"-controlled electronic fuel injection with manifold pressure sensor, intake temperature sensor, crankshaft (well, distributor) angle sensor, and throttle position sensor/switch. It uses constant fuel pressure and flow, so only injection duration needs to be modified to control air/fuel mixture. It measures incoming airflow by monitoring the intake manifold pressure; engine speed, temperature, and other factors are monitored for the purpose of fine-tuning injection duration. Ignition is by a standard cam-driven distributor with an internal D-jet-specific pickup for the crank/cam angle position. This "speed-density" D-Jet system was used on many cars of the period, including Volvo, Jaguar, Volkswagen, and of course, the Porsche 914 (1.7L and 2L engines only; the 1.8L used L-Jetronic -- "L" for "luft" or "air...

On "Microsquirting" the Porsche 914 - Part 2, Which Aftermarket Fuel Injection System?

Which Aftermarket Fuel Injection System? Return to Part 1 Scenario: two Porsche 914s, one 2L 4-banger street car with stock engine, one 2L 4-banger race car with modded engine. Greg's street 914 The street car engine has a fully-functioning Bosch D-Jetronic system, but as noted in Part 1 I don't trust it. It seems to work great at times but every now and then, usually when I'm an hour away from home, it'll have this massive burp and run bad for a bit. Makes me nervous. And it seems to be extremely sensitive to fuel selection; a couple times it just did not like the fuel I got from some stations. The race car's engine is modified and uses dual Dellorto carburetors. I have given thought to preparing prepping it to SCCA's Limited Prep Production regs, which requires fuel injection using the stock throttle body and intake manifold. Combine the two needs and maybe I can mod the street car and learn something about EFI in the process that could apply to ...

The World's Collective Experiences...

When I was a young lad in grade school - the 1970s, back when we were walking to unheated schools with no windows uphill both ways while barefoot - and I was losing important kin, I wondered if we'd ever, someday, be able to connect to people before they died and somehow plug in and download their life's history and experiences and catalog it. It might be mundane, it might be extraordinary, but collectively it would be an absolutely incredible story...right? And yet...today we're doing just that. With the advent of the Internet and everybody pouring out their hearts on the social media sleeves, can't someone in 50 years be able to learn who their grandmother really was? What type of person your grandfather was not only as an adult, but as a schoolboy? Will you have any doubt as to what your great-grandfather did for a living? It's a blessing. It's a curse. But now we'll know.
