Project Screwed - Twin-screw Supercharged 3.0L V6 Project Page (NEW!)
Spring is here & I'm ready to build another guinea pig for my engine management system development/tinkering. This time it's supercharged. I've never been a believer in stealing crankshaft hp to beat heat into the intake charge, but I'm gonna try this out. I'm doing it my way though...
Chris' Engine Calculator Spreadsheet rev 2 (copyright 2002)
Excel Spreadsheet that quickly calculates things like compression ratio, fuel & air flow, hp/torque estimates etc. Since this is an on-going project not everything works perfectly... but the basics are correct.
Quantization error due to a period capturing RPM algorithm calculator - rev 1 (copyright 2002)
that attempts to quantify the error associated with measuring the rpm of an
engine w/ a toothed wheel and period capturing algorithm. I don't know who
in the world would care to leverage the work I did... but I post it the same.
My Automotive Library
It's lame... but I tend to spend more time reading about crazy modifications than actually working on my cars. Here are some of the titles that I've found compelling/interesting for one reason or another.
Design & Tuning of Competition Engines - Morrison & Smith
This book has to be a classic... originally written in the 60's and revised in the 80's, it spans the golden age of motorsports engine development. The authors start with a review of the thermodynamic & physics laws that govern the operation of engines and then jump straight into practical applications. This book covers the aspects of engine balance & cylinder number/layout better than any other book I've read. The last 1/3 of the book is devoted to case studies on the most successful competition engines of the modern era (Cosworth, Jag, Datsun, American V8, etc).
The Internal-Combustion Engine in Theory & Practice Vols I & II. Taylor, Charles F.
These books are extremely expensive (I paid $150 for the set), but... ... wow. Geared for the people that actually design engines for a living, there's way more information than any amateur engine tinker could ever use. The volumes are logically divided into theory & practice with 66% of the information in the 2nd volume. The theory volume is thick... thick reading that is. Still, I found the chapters on detonation, friction, performance, & power estimation most useful. Taylor goes further into subjects like oil viscosity than the other books I have.
How to Hodrod & Race Your Datsun. Waar, Bob.
Ah, the essential text for any Datsun nut. Referred to as "The Bible" in the 510 community, this book covers virtually every aspect of modifying a Datsun 510 or 240Z for street performance or track competition. There are two editions of this book. The first has a more complete section on cams & general valve-train setup written by "Racer Brown" (cam profile designer from the 70's). The second addition trims down the valvetrain section, but adds information on the L18/L20B/L28 engines since they weren't available for the first edition. I'd say buy both... but the first editions are nearly impossible to find.
Design of Racing & High Performance Engines. ed Harralson, Joseph - SAE Press
Interesting compilation of the classic motorsports specific SAE papers published between ~1960 & 1990. This book contains ~20 papers that discuss the development of engines such as Honda's 1.5L 800hp V6 F1 motor & the Ford 427 OHC engine. This book should praised for it's entertainment value & gee-whiz factor, but unless you spend all day developing race engines, you won't gain much. Nearly all of the papers discuss the methods and results the authors used to research/design their engines, but there's not much information that can be used by the amateur. Expensive book... $45 if I remember right.
Fuel Injection - Installation, Performance Tuning, Modifications. Hartman, Jeff
Bosch Fuel Injection & Engine Management. Probst, Charles O.
Nuts, Bolts, Fasteners & Plumbing. Smith, Carroll.
Engineer To Win. Smith, Carroll.
Tune To Win, Smith, Carroll.
How To Air Condition Your Car. Remus & Chisenhall.
Advanced Engineering Mathematics. Kovach, Ladis D.
I don't know why... but this $15 text that I bought used at Powell's has become my best friend. I can hardly recommend this text to anyone that want to learn anything from it though. I use it a handbook & reminder for the stuff I allegedly learned in college. It covers everything from differential equations & fourier transforms to Green's functions & moments. There's also a section that directly discusses Maxwell's equations which is why I bought the book in the first place. Again, don't expect to learn anything from this text... it's a great resource to have handy.
