RACERS, ENGINE BUILDERS, HEAD
NOVICE BEGINNERS TO SEASONED PROFESSIONALS THIS CLASS HAS SOMETHING FOR
For anyone that is in the engine
building business, or wants to do cylinder head
work this class is invaluable. The amount of
information that Darin gives you is mind numbing
and will take most people weeks if not months to
decipher (after re-reading the text, and
listening to your tapes if you choose to tape
it). The biggest benefit is you get Darin’s real
world experience and can go over specifics; he
not only gives you the answers but shows you how
to find them on your own.
Having been to numerous conferences and seminars
over the years this is by far one of the best.
We most only give a few hours to go over the
content Darin is there for a full two days, and
you get to interact with some really great minds
who are attending as well.
Applying just the basic
principles and guidelines you passed on to me I
have been able to get solid gains in not only
peak HP but really stout torque gains and much
wider power spread than anything I ever achieved
before. One of the engines I was working
on at the time we spoke has gone on to set a new
class record at Bonneville, and one of my recent
road racing engines is as fast as any ever in
the class but has a power band a good 2,000rpm
wider than anyone has ever heard of.
Once again I’d like to thank you
for inviting me to your seminar. Even
though I’m not a cylinder guy, or porter I found
it extremely entertaining, and educational.
You’re method of teaching is very similar to
what I enjoy, free flowing where you work from
an outline and go with it.
I first met you in the fall 2007
at Reher Morrison school and could not have been
more impressed. So as soon as you released
information on this school I was all over
booking it. Your presentation at the University
of Northwestern Ohio was equally as impressive.
I realized that I was in the wrong room right
away, I do not have the experience level needed
to apply or use the bulk of the information you
presented. I am not used to walking into a room
and feeling so humbled when anything automotive
is the topic. Now this is not to say that I
don't realize my limitation I just seldom feel
like the least educated and under informed
person in the class room. You are one of the
most polite soft spoken people I have ever had
the pleasure of meeting in this industry. You
always seem to enjoy sharing your knowledge as
opposed to hoarding every little detail you have
learned, that in my opinion makes you one of the
most generous people in racing.
Thank you, thank you, and thank
you! Finally, there is someone to teach what no
one else talks about. When you said that my
learning curve would take a big leap forward, I
was skeptical. You were right and I am now a
skeptic no more..
I have seen many presentations at
places like PRI, the AETC and many other venues.
Your was, by far, the best I have ever seen. You
actually made sense of a topic that has
perplexed me for many years. It’s a very complex
subject matter and you seem to be able to put it
into context and make people understand. Keep up
the good work.
After attending Darin's
class.........well, if I knew what he was going
to disclose/ teach before I signed up, I would
have paid $5000.00 for the course. Darin poured
his heart out about real world race engine
development & technology on some of the most
sought after engines in the racing industry
today. Not just book knowledge, actual data,
formulas and results from years of testing and
claiming world records and world championships
in almost every class of racing. The class was
priceless, the records Darin holds are proof of
his teaching, and his down to earth logical
approach was the most easiest of conditions to
Thanks Darin for all your help.
I went home and took a cylinder
head intake port that I have been working on for
weeks. I have been through no less than three
other ports trying to get the thing to flow.
I now understand how I was going about things
all wrong. I used the calculations and ratios
you gave did the short side exactly the way you
described and the port worked! The first shot it
worked better than the three previous attempts.
It now flows 18cfm more and its smaller and
faster. I can’t thank you enough.
Darin, Your cylinder head /
induction class was very informative. I learned
a lot and Was able to confirm a lot of air flow
info that I had picked up over the last few
First let me say I've known Darin
for many years. Not only is his knowledge first
class, but so is Darin the person. He is one of
the very few people I've known that would bend
over backwards for you! His passion and thirst
for learning, I've never seen duplicated. Now
the class. Weather your a seasoned Professional
or a novice beginner, you must attend. Darin
opens your eyes on the PROPER way of designing
an induction system. He doesn't just give you
"formulas" he gives you real World experience
and knowledge. The knowledge he so willingly
shares with you. This type of info would take
you YEARS to achieve! At any cost for the class,
its priceless! After the class, Darin still
isn't done. If you have questions, he will
answer them. You get home, you have questions,
he will answer them. What Darin has provided for
our sport is priceless. Do yourself a favor and
go, it's an experience I will use everyday in my
