Ron,
Hey, I learn something new everytime I work on the Dak. (Always a humbling
experience, "Ah man, what did I go and do that for?") I may know a little
bit about engines, but I'm far from knowing a lot about them. Thanks for
the article. I really appreciate it, and I'll definetly read it. Actually,
I'll probably print it out and keep it with the rest of my library. I don't
even know who Dema Elgin is. Guess I'll learn more than one thing when I
read this article.
Thanks again,
Rich

Hey Rich,
I know that you know a lot about engines so don't think I'm trying to say
otherwise. When people customize their camshaft, they generally listen to a
lot of hype about high lift, high duration, overlap, etc. The principles
behind the 4-stroke engine are varied and numerous but they all come down to
the basics. The more radical you make your cam the less efficient your
engine is on the low end. There is an excellent article written by Dema
Elgin (yes, he makes cams) but don't read it because he's trying to sell you
a cam, read it because he gives an extremely good overview and beyond of
4-stroke engines and why they run like they run. I've read his article many
times and each time I figure out something I didn't know before. A lot of
what he says probably applies in your case. I don't know if any of this
will help you solve your problem but it may help you to see what it is. The

Ron,
I installed a rather large cam. That's what is pulling it down.

That doesn't sound right. Why would your vacuum change because of mods?
Sounds like you have a leak somewhere.

Is anyone familiar with how to increase your engine vacuum? After my last
round of 318 engine mods, I discovered I'm only pulling 11-11.5in of vacuum
at idle. This doesn't work on the street. Any suggestions on what I can do
to bring it up?
Thanks,
Rich - Ashburn, VA
