[Diy_efi] : tuned port manifolds

Mon May 13 14:13:29 GMT 2002

Just had a peek on Amazon where this book is on a special offer deal =
with the Corky Bell book :-). The reviews are interesting. A race car =
designer raved about it, everyone else was luke warm. Hrrrm.

Alan,

    The ISBN is 0-8376-0309-9 and the Bentley Stock No. is G309. I =
recently
purchased a Cam Doctor from Quadrant Scientific and they included some
camshaft design principles that were written to inform the user on how =
to
interpret the data gathered from the machine and apply it to real world
applications. This may be what you're looking for.

    I don't know if one can purchase these papers separately, but they =
may
know of other texts on the subject that are currently in print. If your =
not
familiar with the Cam Doctor, it is a machine that measures a camshaft's
dimensions....digitally. It uses a digital stepper motor to rotate the =
cam
in a "V" block, while a comparater measures the lobe, at which the data =
is
transfered and displayed on a PC. It does so in a full 360* range and =
can
detect lobe lift, overlap, heel/toe ramps, duration, individual lobe =
timing
tolerances and gross lobe ramp acceleration vs. time in crankshaft =
degrees.
(overlay)

    Unfortunately, I don't know the URL for it, but it's manufactured in
Louisville, Colorado....so, possibly a search?

Hi Phil,
I'm glad this topic has appeared as I have been looking for a good
authorative text on inlet and exhaust design for some time.  Does the =
book
have an ISBN?  If so can U forward it to me?   I am a physicyst by =
dicipline
and don't have any formal education on engine design other than the =
normal
applied physics stuff re thermodynamics and all the calculus etc.  I'm =
also
looking for some in-depth texts on CAM design and so on... Do you have =
any
pointers?
