Sound of a Buick straight 16 cylinder

Back in 2020 to 2022 I build a Streamliner inspired by Mercedes record car from 1938. I build the Streamliner with two Buick 248 and with dual intake. The premier run was 2022 at a legendary beach for speed records back in the 20´s (Pendine Sands in Wales).

The Streamliner has participated in few events mostly for show runs. I wanted to share the Sound of a straight 16 Buick engine (16 cylinder fire order).

Enjoy :) Streamliner C-16 Recreating History &

What a project! Great results! The text refers to the second engine's crankshaft being clocked 11,250 degrees from the first one to provide a 16 cylinder firing order. Many North Americans, reading that, might think "Huh?", as I did, before realizing we would have better understood 11.250 degrees. I'd like to know what the firing order is, and whether cylinders are paired to fire simultaneously. The pictures of the work on the distributor rotor suggest that. I'm guessing the 248s are the later ones that use insert crank bearings, and I wonder how fast you dared to spin the engine. With even inline sixes susceptible to crank twist at high revs, that's only going to be a bigger issue with an inline 16. Wow! You guys had way too much fun on this, didn't you?
 
The 11 1/4 degrees of separation sounds a bit odd to me. If a single cylinder engine fires once every 720 degrees of rotation (twice around for the crankshaft), a twin fires once every 360, a four cylinder once every 180 degrees, and an eight cylinder once every ninety. It goes to follow that a sixteen cylinder engine should fire every forty five degrees of crank rotation.

Anything else would seem... odd. Not impossible, Harley Davidson motorcycles aren't strictly spaced like other twins might be, but it gives them that distinctive "Harley" sound. Some folks like that.
 
Thanks :) Yes! We did have lots of fun building this unique Streamliner, despite all the challenges to build a Straight 16 cylinder. We did try to run the engine with a 16 cylinder distributer and it did work, but not 100%, so we changed back to two distributer in the end. The 16 cyl. fire order is 1,9,6,14,2,10,5,13,8,16,3,11,7,15,4,12. I did try to attach pictures of the 16 cyl. distributor and the fix coupling we manufactured to fit between the two engines, but it doesn't work in the editor :-( It's hard to estimate the top speed, but the theoretical speed was set to 136 mph. That speed and RPM might be too big challenge for the engine and the car.
