2006 SAE International Motorsports Conference & Exposition
(added 11 December 2006)
SAE paper #2006-01-3631, presented
at the Biannual MSEC in Dearborn, Michigan on 6 December, evaluated
21 crash tests of nine different head and neck restraints. Guess which
product kicked crash lab butt? Click here
for a hint.
A great book on how to begin racing (added
17 October 2006)
We have had a policy of never putting up links to other sites, but we
ran into something that is just too valuable for the new racer to be
ignored. It is a book on how to get started in racing and will save
the newcomer tons of time, money and aggravation. Go
ahead - take the wheel...
Rejects SFI 38.1 Requirement
(added 20 September 2006)
At its annual meeting (August 2006) the Board of Directors of the Sports
Car Club of America rejected a proposal to require that all head and
neck restraints used in SCCA events be "SFI certified". More
info is here.
We've Moved (as of 1 July 2006)! (added
29 June 2006)
Since we are usually out fishing it doesn't really matter where the
office is, but the new phone system is pretty impressive. With 24/7
call notification your off-hour voicemails can even track us down over
the internet. Plus, we now have toll-free calling from the U.S., and
Skype users can call free from anywhere in the galaxy. The details are

Please don't do this; we want you to buy an Isaac®

Helmet Mounting Kit (added 17
months of extensive laboratory testing, we are pleased to announce the
availability of a hi-tech structural adhesive that can be used to attach
the Isaac® mounts to your helmet. This technology is easier than
using nuts and bolts, takes less time, does not have to be kept tight
or maintained in any way and does not, in any manner, affect the
structure of your helmet.
Before you roll your eyes in disbelief, know that this type of adhesive
is used in miltary applications such as air-to-air missiles and various
marine environments. Laboratory testing proves that it is several times
stronger than the loads experienced in a crash test.
Available for immediate shipment.

Article about Isaac® (added
7 April 2003)
Marty Tyler has written an interesting article about the Isaac®
system. Not satisfied with your typical interview with the company,
she also contacted customers and race fans. One avid race fan, a brainsurgeon
who has been seen doing some hot laps of his own, explains why Christopher
Reeve survived and Dale Earnhardt didn't. The link is here.
We have added a Racers' Comments
page to the Web site. Real racers who have used Isaac® systems
in real race cars on real race tracks tell you what they think.
No professional photographs or sponsor logos.
If you are a racer and would like to chime in, send
us your comments for posting.
Want to upgrade you Head And Neck System to an Isaac®? Now is
your chance to trade in your HANS® device. We are looking for a
few specific models, so contact us to see what yours is worth.
The Isaac® product line has expanded once again with the addition
of the Basic model. See the Product Info
page for details.
You know how you can buy a "Demo" car from a dealer,
usually at an attractive discount? The car has been used very little,
has never been crashed and is in perfect condition—except, maybe,
for that onion ring the salesperson dropped under the seat one day when
they dashed out for lunch. Same with Isaac®. We have a handful
of Isaac® systems we have used for track testing (not crash testing!),
shown as demos, or lent to racers for a day at the track. These systems
are in perfect condition, except for cosmetic things liked scratched
finishes or labels that have gotten dirty from handling. They are just
like a new Isaac® after you've taken it to the track a few times.
We have cleaned these up (we even threw out that onion ring) and are
making them available at a 15% discount.
We have changed all helmet mounting hardware to stainless steel.
We have used galvanized mild steel in the past out of a concern for
the racer having to cut the bolts after installation. Cutting stainless
steel is difficult compared to mild steel. Most racers, however, have
access to power cutters (e.g. Dremel® tool), so this should not
be an issue.
Alloy Model of Isaac®
Deposits are now being accepted for the extreme-impact, titanium-alloy
model of Isaac®, expected to be available in the spring of 2003.
This model has a theoretical protection level for impacts up to 150Gs.
The increased performance of this model comes from the extensive use
of a high-grade, corrosion-resistant titanium alloy known as "T64ELI",
or Ti-6Al-4V ELI per ASTM specification F-136. It is pure titanium alloyed
with 6 percent aluminum, 4 percent vanadium and processed in an "extra
low intersticial" manner to improve its corrosion resistance. This
alloy has a very high strength-to-weight ratio and is used in nuclear
reactors, military aircraft and structural biomechnical implants.
The titanium Isaac® is priced at US$3,250. A US$500 deposit will
hold your order. All orders will be filled on a first-come-first-served
Support (Side Impacts)
Initial computer simulations suggested that the Isaac® system
may offer significant lateral support to the head and neck. Revised
computer models, tuned to incorporate the specific shock absorbers used
in Isaac®, indicate a load reduction of at least 50%.
should be noted that this level of protection was attained without significant
loads to the shoulders.
This is consistent with observations made by racers who have commented
that Isaac® seems to support the head during hard cornering, expecially
on rough racing surfaces.
