As with any story, there
is
a “short version” and then the rest of the story. Here is the short
version of how we did with the RideTech 33 Ford this summer:
• Battle at the Banks –
didn’t run the car…steering not done
• Nashville Goodguys – ran the car with old hard tires, no swaybars,
and frontend chatter – finished 4th in Pro class
• Midwest Musclecar Challenge –
car ran great, then broke camshaft on
the fourth lap
• Optima Qualifier Texas
– ran
great, top 5 finish overall
• Optima Qualifier Road America – ran great, top 5 finish overall, wore
out clutch
• Motorstate Challenge – spun car
twice, still finished 5th on the road
course, but would not run for autocross
• Run Through the Hills – broke power steering, coil died, but still
finished 8th overall
• Goodguys Indy – everybody was
really close…5th overall
• Scottsdale Goodguys – very close
racing…3rd overall
• Del Mar Goodguys – the 33 worked
great on this track…1st by a lot!
• OVERALL GOODGUYS PRO CLASS and
STREET ROD CLASS 2012 Champion!
And here is the rest of the story
for those who can stand even more of
my relentless drivelings…
At RideTech we use “suspension research and development” as a great
excuse to build hotrods. A couple of years ago we decided to do
something that was a bit more “traditional” looking…something
light…something that would show hotrodders that you didn’t have to
necessarily build a Camaro, Mustang, or Corvette to be cool and go
fast.
Enter
the RideTech 33 Ford. Starting with a Factory Five chassis and body,
the project migrated from a simple “throw it together and go fast”
deal, to a full on 3000 hour racecar/street car/fabrication exercise.
[any of this sound familiar?] The 33 actually uses a lot of used,
fabricated, or otherwise pre-existing components. The 427W engine used
to be in my 69 Mustang [before an oiling problem left the crank laying
on the track at Road Atlanta a few years ago], and the Rankin
clutchless 4 speed transmission was a remnant from the Jasper Engines
NASCAR program a few years ago. The Winters quickchange rearend was
bought new. The 6 piston 14” rotor Baer Brakes were left over from
another project, as was the Holley Dominator EFI system, the MSD
distributor and Digital 6A box, as well as the Racepak dash. We then
spent from November 2011 to May of 2012 fitting the body, fabricating
the double paneled insulated sheetmetal interior, building the seats,
making the stainless headers and oval exhaust system, fitting the
Tilton pedals and IDIDIT tilt steering column, creating a full
stainless rollcage, installing a Fuelsafe fuelcell and fire system, and
making all the little hinges, handles, brackets, and riveted sheetmetal
trim pieces that appear all over the car.
The 33 incorporates
some suspension stuff that I had been wanting to try for awhile. The
rear suspension is a “wishbone” design…2 bottom links and a single “A”
arm on the top to control both lateral and axial rotation. While on
paper the rear roll center seems a bit high, in practice the car is
stable, predictable and fast. I intend to use this design more often!
The front suspension retains the original Factory Five control
arm pivot points, but we built new control arms that were just a little
prettier, with delrin bushings and replaceable balljoints. The biggest
thing we did to the frontend was to change the steering system
completely. The car comes with a manual rear steer rack that is, in my
opinion, just a bit small to get the job done with a 315mm tire on the
racetrack. We installed a Woodward front steer power steering system.
Because it was a complete custom installation we had the latitude to
work with rack location and steering arm design to reduce the bumpsteer
to under .050” through 6” of suspension travel. It is beautiful to
drive on the street…or at 150mph on a rough racetrack!
Another
major variation from the FFR design was to cut the recommended spring
rate in half and build front a rear swaybars. The result is that the
car not only performs well on the track, it rides comfortably and is
very tunable to a variety of track conditions via shock, swaybar, and
tire pressure adjustments. We debuted the car [at least visually] at
the Battle at the Banks event in Salem, In. on May 5th. We didn’t run
it there because the steering was not completed yet. The first driving
event was the Nashville Goodguys autocross in May. With some old, hard
tires and no swaybars, the car did well, but we knew there was so much
more potential.
By the next week at the Midwest Musclecar
Challenge we had swaybars built. We made 4 autocross laps and the car
was just getting fast when the distributor gear on the camshaft died.
After that was fixed we took the car on the Hotrod Power Tour and the
first Optima Qualifier in Dallas Texas. This was also the debut of the
new Falken 615k tires. What a dramatic difference! The 33 ran top 10 in
all the segments and nothing broke! Later in June we went to the 2nd
Optima qualifier at Road America. We did very well there too but wasted
the clutch in the process. Back home to get ready for Columbus
Goodguys.
I spent most of the ridiculously hot summer tuning
and learning how to drive this thing! It was fast, but not as fast or
smooth as I needed it to be. The biggest problems were the explosive
acceleration [light car, lots o horsepower, and a really light carbon
clutch], a front end chatter that I could not seem to locate, and an
obstinate EFI system [or so I thought]. At the Run Through the Hills
event in September we resolved 2 of the problems: the EFI problem
turnout to be a bad coil…it finally died, we changed it, and it has ran
perfect ever since!. The other problem resolved was the front end
chatter. It was bad enough that the power steering slave cylinder rod
broke off. Bad news…BUT the frontend chatter went away! Now instead of
chasing an illusional mechanical flex problem, I started looking at the
hydraulic system. A quick call to Woodward steering [why didn’t I think
of THAT before?] got the answers: the pump was cavitating. Move the
reservoir up, increase the return line size and make sure it flows
evenly downhill to the pump with no dips or humps. Problem completely
fixed!
The last problem that we fixed was the very cool but
somewhat temperamental 5.5” carbon clutch. We replaced it with a
Centerforce DYAD unit just like we had in the 48 Hour Camaro all this
year. What a dramatic difference! It went from a juvenile delinquent to
a refined warrior…and got REAL fast and predictable. NOW I could
concentrate on learning how to drive the thing! We went to Texas
Goodguys and won. We went to Putnam Park to test on the road course to
prepare for the Optima race in Vegas…it was perfect, we changed
nothing. On to Vegas!
We felt really good about the Optima
race in Vegas. The car was good and we were ready. I felt we could run
top 10…maybe even top 5. The crowds at the SEMA show loved the car! The
drive to Pahrump was uneventful [if a bit noisy from all the trans and
rearend gear whine!] The first event was the autocross…we placed 5th!
Next up was the road course…all was going well until the in car camera
fell of the windshield and got tangled up in my feet. The race director
very graciously allowed me to make another attempt. 1:52…3 seconds
quicker than the 48 Hour Camaro last year, and good enough for 12th. On
to the speed stop. I knew this was traditionally my weakest event and
that the competition from the 1200hp all wheel drive, ABS equipped
Nissan GTR [and several other cars] would be nearly insurmountable.
Well, I have no idea how, but I won the speed stop! Now we were in good
position to do well overall, assuming the design challenge portion went
ok. It must have…we tied for 3rd place overall!
So what’s next
for the RideTech 33? Well, now that it’s respectably fast, we’re likely
going to put some pretty paint on it. The original plan of wrapping
that car at the Hotrod Trade Show last March was waylaid by the
dumbasses at the Mutoh Corporation and the Fellers Corporation who, one
week before the show, decided that the project was too hard for them to
do. Nice. Other refinements will be cleaning up some mounting bracketry
and wiring routing, building a hood and hood sides…and changing to air
suspension. Now it’ll get REAL fast! We had a LOT of support throughout
the year on the 33 Ford. Centerforce built us a great clutch. The
Falken Tires are unbeatable, as are the Baer Brakes. Forgeline built us
a really cool [and light] set of wheels. Holley went out of their way
to get this thing to run [even with a bad coil ], Tony Woodward is a
steering system genius, and Sunset Racecraft builds one badass Ford
engine. …and the engineers at Fox Shox made us all look like heros on
the track. The triple adjustment capabilities of our new shocks has
really proven its worth this year! Greg Schneider, Kurt Blackgrove and
Dennis Neihaus at our RideTech shop built a fast reliable, cool looking
33 Ford. It was my privilege to get to drive it every week!
