Recently became addicted to combustion engines, looking for books to read

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

"Smokey yunicks horsepower secrets" its an old book, but the pages describing porting technique were gold for building my V8 25 years ago, the guy was a guru in his time.

There is also one by Phil Irving, but delves into subjects that predate Smokeys research. Very old book.
Who came up with dimpled intake ports, they work incredibly well.

Uncertain, I am sure it was pioneered in top fuel bike engines, not everybody does it properly.
My understanding is parts of the port reach supersonic velocity (floor, radius), only these areas need dimples, not the roof or bowl.

A well designed port does not need dimples (ever seen dimples in an F1 port?).

Furthermore, in a port, dimples would not be the most appropriate method to initiate a turbulent boundary layer (which is what the dimples do). The flow orientation in a port is known unlike a golf ball which is (spinning) constantly presenting a different face to the flow direction.

Nothing like being on-topic!

Anyone that has nice/informative books on the working/tuning of reciprocating combustion engines?
I want to learn things like how manufacturers choose the lay-out, what gives the engine its horsepower, etc.
I have basic knowledge on how engines work.
For daniellammers.

You may find this Len Setright book (linked below) to be of topical interest, per your request.

This website explores those ideas more in depth;

Thanks... I think. That man can pontificate like few others. He obviously never took Johnson's advice to heart “Read over your compositions, and wherever you meet with a passage which you think is particularly fine, strike it out.” The pictures are fun.

Indeed Greg, & while Dr Johnson himself had his critics ('Blackadder 3' did a 'splendid job' on him, IMO)
yet notwithstanding Setright's wont for wax-flowery phrasing, as you duly remark, the turbo-compound
diagram shown on page 007 of the cited link - is seemingly fairly precient re: current F1, well of course,
'cept for F1's wasted effort in 'pumping' - via rules-prescribed 4T/poppet-valve constraints...

Dunno 'bout that coaster, the BMEP of the Junkers Jumo KM8, an oversquare 4.3 litre rotary disc-valve
V8 which made 275hp @ 3650rpm (in the link you cited*) seems a bit impressive, let alone the 440hp/Ltr
of the final 125 G.P. racers, which also utilized rotary disc-valves, & were naturally-apirated, to boot..

To be honest, while I grit my my teeth at the ornate phrasing, he tells a good tale (yeah, I'm enjoying it), and as I said, the pictures are fascinating. Pre echoes of the Bourke engine in 1905. The amazing and even slightly successful Bristol axial engine. It appears that it is axiomatic that if somebody develops a pumping mechanism, somebody else will turn it into a breakthrough engine, which will fail, 99% of the time.

Electric superchargers (actually a scavenge blower in this case) seem to be on the rise. Quite enjoyed this link posted by JAW in the Vehicle Project thread.

There was a publication at the city library stating the discs on the KM8 were cast bronze and without seals, limiting the life of the motor (warping disc, scoring) which was not an issue since it was a torpedo.
With seals and cooling and more development, imagine.
