A book on the Penske/Benz push-rod engine.
Not a lot of specific details regarding the engine, but a lot which can be inferred. More about how it was kept secret.
I certainly hoped for more about the engine (was it worth sacrificing balance for the 75* V?); only near the end was there mention of an interview with a Honda engineer who admitted they had worked on the CART engine base on F-1 data and had ignored how methanol burned compared to the high-octane dino-fuel used in F-1. Care to enlarge on that? Nope.
The book was written by a somewhat tech-savvy publicist rather than any of the engineers involved, and maybe there's an SAE paper on it which has yet come to light.
Still a good read with enough drawings to keep gear-heads involved.

Software guys...

...forgot to include...

If someone can tell me how do delete the copies, I'd be more than happy to.
How much did we pay for this software?

...a "delete' function.

Screw it...

Those Honda engineers are messing with you.

David,
That worked once; now I get "edit", "report, or "reply with quote". No "delete".
Was this stuff done by the guy who gave us the bottom-sender gas tank?

I managed to delete the body of my post as you can see Ron by putting one word in by "edit." Inputting nothing to remove the entire post resulted in a message saying there was insufficient content or some such.

David,
I knew that was a work-around, but in one case, I actually found a "cancel" tab, which has since disappeared.
Forget it; these guys aren't good enough to design a bottom-sender tank; they're responsible for the single-mount 741 trans!

I was just going to say single-mount 741 trans!

Ron: I assume you are referencing the Mercedes Benz 500I 3.4 litre V8 built by Ilmor/Penske in 1994?

See Karl Ludvigsen's Classic Racing Engines page 210 . Peak power of 1,024 BHP @ 9,800RPM.

That's the engine, and that dyno result was shown, with qualifications. While Ludvigsen's a good writer, I'm looking for more than a page, and his 'popularizations' can be facile; he spends no more than a couple of pages on the Ferrari Colombo engines in his book on V-12s, 1500cc to 4.5L. Weak tea.
This books isn't bad, but it's simply not as good as it could be.

Ron:

I agree, a few scant pages. Still, all I have been able to find out about that interesting engine. I was thinking about making a special cylinder head for a pre-war Mercedes engine, and was thinking about valve train geometry along those lines.
