To all Star Formula
Mazda racers:
In fewer than 30 days since the date of our last bulletin, there have been several
developments which we thought you would like to know. The so called "off"
season is when many decisions are made which determine the plans and course
of the following season's programs for many of us, and we want to give you all
the available information as far ahead of time as we can. There are several
projects and issues which have not been completely worked through yet. However,
we did not want to wait until resolution of each and every item, because then
we might never get any info out! What follows is not in order of importance,
necessarily, so try to sort through to catch the matters that are of interest
to you.
Pro car motors. The Series impounded the motors from the top three cars after
the Mazda Raceway finale and dynoed them again to see if any changes may have
occurred during the season's competition. Series officials, on hand for the
tests, were pleased to find that all three motors were within two horsepower
of each other, and all were about two horsepower better than the dyno records
indicated they were when originally tested and installed in the cars. The small
increase is attributable to the reformulated MS-98 fuel, introduced at Road
Atlanta in September. It is interesting to note that two of the motors (McDowell
and Frisselle) had run 9 races each and one was an exchange motor (Schiavo)
with 3 races on it. So it seems that neither parity nor longevity are problems
at this time.
Also on the subject of pro car motors, we have determined that we can finally
release the ceramic seals for competition in January '05. Testing indicates
excellent reliability with the latest configuration and no loss of power. The
principle advantage of ceramic seals is longer life, therefore more time between
rebuilds. Long term, they are reputed to retain better torque numbers through
the later life of the motor. Please consider carefully whether and when you
may wish to have the ceramic seals installed in your motor. If you are ready
to do a rebuild/refresh on your motor, it probably makes sense. If your motor
is running fine, we would question whether it is a good idea to do a premature
rebuild, to install parts which have the main justification of extending the
time between rebuilds. For those who will make the change regardless, please
make arrangements to have your motor done well in advance of any critical dates,
like Sebring. It is simply not possible to do everyone's motors at the last
minute. We will try to set up "reservations", so motors can be turned
around promptly. We will also have exchange motors available, with and without
ceramic seals, for trackside support. Ceramic seals add about $2000 to the price
of a rebuild, if the motor does not already have them.
Please take advantage of the "competitors page" on the web site www.starmazda.com.
All the latest info, especially servicing and compliance stuff, will be posted
there regularly. It should serve as a good reference during the season. There
is a "free" offer explained there now, from REM surface treatment,
for pro series cars. Those who wish to participate can get 10 pairs of change
gears for the FTR treated for "free", if you agree to run the REM
decals on both sides of your car and cooperate in evaluating the effects of
the treatment. Note: REM is legal for pro cars only, standard FMs are prohibited
from using it. There is also some useful information about a small internal
mod to the FTR diff, to aid in lubrication. This was suggested by Craig Taylor
and approved by Hewland. Drawings are available from us, your dealer, or Craig.
The "factory team" has published the set up sheets from the championship
winner's car there, as well. We are sure some of you will be interested to compare
notes for the various tracks. McDowell's data traces will also be available
there soon. Check out the info on St Pete. It is going to be a very special
event.
IMPORTANT: There have been some reports of joints in the pro car steering column
loosening up (these are the small universal joints most of us call "apex
joints"). Check yours. There are two per car, just above the rack. You
can usually feel any play that develops by grasping the joint through the rubber
boot and manipulating the steering. You should not be able to detect any slop
in the joint. If in any doubt, replace the joint, or joints. Make sure you use
Apex brand joints. These are mil spec joints and very reliable. They should
be available through your Star Race Cars dealer. We are not sure of the brand
of the ones that have been reported suspect. Note: It is always useful, should
you ever experience any part failure, if you return the broken part to us for
inspection. It can help us with evaluation of suppliers and designs. In the
end, you get a better car.
Change in pro car front wing end plates: For 2005, the front wing end plates
will be "trimmed" along the bottom edge to increase clearance from
the ground by 1/2 inch. The four holes, not previously used, paralleling the
lower edge will be raised 1/2 inch, as well. These holes will accommodate installation
of a 1/2 inch by 1/2 inch piece of aluminum angle, which can be installed parallel
to the ground, to offset any aero loss from the reduced height of the end plate.
The purpose of the change is to reduce contact/damage to the front wing main
plane.
Nominees for the Red Line Oil shootout have been determined. Tests in a pro
FM will take place in February at Buttonwillow Raceway. The winner gets a race
in the 2005 Star Mazda Series North American Championship presented by Goodyear.
The nominees are: David Stover (Southwest), Rob Nicholas (East), Zan Smith (Rocky
Mountain), Fabio Castellani (Central), and Kyle Kelley (West). Congratulations
and best of luck to all.
Tire compounds to be used for 2005 North American Championship races have been
set. The following tracks will use the 250 compound: Sebring, St Petersburg,
Road Atlanta (Apr), Mid Ohio, Portland, Road America, and Mazda Raceway Laguna
Seca. The following tracks will use the 430 compound: Watkins Glen, Infineon,
Mosport, and Road Atlanta (Sept). Pikes Peak Raceway will use oval compounds,
620 on the left side and 800 on the right.
SCCA has published that the pro car will be legal for National competition,
starting January 2005, in the FA class. Our reading of the published specs leads
us to believe that only minor differences from the pro specs will be involved:
5 pounds higher weight with driver, minimum wing angle, probably some sound
level adjustments to meet club limits. That is about it. Star Race Cars and
our dealers plan to support club racers in all Star Race Cars models with at
track services. The schedule for the West series' for both standard (including
4 port Renesis cars) and pro cars in 2005 will include:
Feb 5 California
Speedway double regional
Apr 30 Phoenix double regional
Jun 18 Buttonwillow enduro
Jul 8-10 Thunderhill double regional
Jul 24 Laguna Seca regional
Aug 5-7 Laguna Seca regional/national
Oct 30 Buttonwillow double regional
Best 9 results
of 11 races scheduled will count. Standard cars will be scored separately from
pro cars. The two series' will run on the same venues/weekends, but each will
have it's own championship.
Testing and development continues with the 4 port Renesis conversion for the
standard FM. There seems to be some confusion on this subject. Let's try to
clarify what is intended. The 4 port is ALMOST the same motor as the pro car,
but with some important differences. It is not a dry sump motor. The intake
system is much simplified, as is the ECU to run it. The rev limit is lower (6850
vs. 8300). Still, it will need some de-tuning, to be equalized with the unconverted
standard cars at first. Once the majority of the standard cars are converted,
we can take up the subject of "turning up the wick". Meanwhile, converted
cars will have an incredibly user friendly, under stressed, modern motor, with
parts availability assured for the next several years. Our target price for
the conversion, net of the take out motor sale, is about what it costs to do
a regular motor rebuild. Once all the parts needed to convert are defined, the
conversion will become a "kit" for easy installation. The official
SCCA rebuilder for the 4 port motors will remain Daryl Drummond. If you are
interested in converting to the 4 port, and have questions, contact your Star
Race Cars dealer, or us. We have been asked if the 4 port will fit into the
MSR. It does.
2005 Series rules and entry info will be coming soon, in the next bulletin.
Star Race Cars will be closed from 24 Dec 04 through 2 Jan 05. Happy Holidays!
Sincerely,
Gary Rodrigues
