If you're a tech junkie (like me), you will enjoy seeing what was then the state of the art (automotively speaking) vs. now.

The epitome of piston engine development we see being revisited today, i.e., 4 valves/cylinder, fuel injection, water injection dual stage supercharging, cam phasing, etc was known at the end of WW-II - engines used in aircraft specifically. So, I find the "gee whiz" press releases and tech writers falling all over themselves to marvel at some of the automotive engine tech du jour as being so "cutting edge". Oh, please! But, I digress...

Interesting (YouTube) article anyway...

A fun video Paul. I love the '65 fuelie, but once I had a ride in a friend's 396/425 back in 1965, I was hooked on cubic inches. I have to say that I am still a bigger fan of the 427 in the C2 era. Dream car: '67 427/390 with A/C and outside pipes. Pipe dream, but still... --Bob

the old radial engines are a marvel. Udvar Hazy and the Richmond airport museum have some very cool cut aways. These engines were the big doggies and pushed the envelope of boost, nitrous and just plan big!!!

I'm a fan of the old engines, they are fascinating.

The indy museum is another must do. They have the old thumpers going way back up to the current state of the art.

I'm going to get a seat in a 2009 cosworth for helping a buddy out, I can't wait. I have to behave but that car is an "unrestricted" cosworth that can provide upwards of 1000 hp in a car with uber down force.

The outlaw indy car has the pop off valve bolted down so he can run "non race legal" boost and the cosworth just laughs and pulls harder

"that's more my girl" the trip down the mine shaft is something on my bucket list that might actually happen. I'm holding out for indy, I helped pit the car a few years back fopr vintage parade laps and it's something I'll not soon forget.

Interesting video for WW2 piston engine fighter buffs.
Amazing progress between 1935 and 1945. Very interested to learn lube oil channeled through the crankshaft link our LT5 crankshaft was considered a big deal back in the day.

Germans were the first to employ automatic engine management system on the FW 190 for controlling manifold pressure, timing, and fuel injection which relieved the pilot to focus on more important things during combat.
Lack of automated engine control was the reason the US turbocharged P38 Lightning and P47 Thunderbolts fighters were considered complicated to fly in combat where engine management had to be done manually by the pilot.
