Bonneville SpeedWeek 2016/World of Speed...Cosworth Electronics Testing
Mike and the
2016 and the Bullett heads for SpeedWeek: Mike Geokan and his creation 24 years after conception. Now it's 2016 and, one day after a serious operation, 100 pain pills in the trash, Mike's checking the Bullett, which is headed for Bonneville to test the revamped engine with new Cosworth Electronics, fly-by-wire throttle, 8800 parameters, and electronic phase anti-phase boost control...Headed for the real Dyno, the Great White Dyno, for testing. Mike stays home to spit nails at the wall.
Here we do an actual flow test of the Injector Dynamics ID2000 fuel injectors on the Cosworth Pectel SQ6M Simulator at 3 Bar and 6700 RPM to verify we have exactly 500HP worth of fuel. We do. We have no intention of melting the motor down. The ID2000's are perfectly matched. We'll dial in a rich fuel curve to start with, then lean it back after our first run. The loads at Bonneville are motor killers.
Cosworth Pectel SQ6M Engine
Management Controller. Cosworth engineers were probably thinking of
quad-cam V12's with 48 valves and dual Fly-By-Wire throttles when they
designed this puppy, and not a pushrod V-Twin with two valve cylinder
heads. It's perfectly at home however, and can control anything,
including wheelies...Not that we are doing wheelies with the Bullett on
the Bonneville Salt Flats.
Last second change of plans. Brother Speed's "Two Bills" Bill volunteers to tow the Bullett Race Trailer with his Ford Diesel and head to most harsh, hot, eye-fying environment...the blindingly bright Bonneville Salt Flats, in spite of a serious eye infection in both eyes. Eyes swollen and beet red. Hey, whatever it takes. Ex Hard Hat Navy diver and a life of working in extreme environments...no big deal.
"Two Bills" Bill right. Mike Geokan center. Halt Hennig left. Walt hauls the Rhino on the tilting trailer we use to retrieve the Bullett after each run at the Salt Flats.
Ride to the Salt
Bryan and Nick Stock ride their chopped Dressers from Boise to Wendover with stops at Wendell, Jackpot, and Wells before the final push to Wendover and the Bonneville Salt Falts. Was it hot? Well, not in the air conditioned trucks, but on the Harleys it was searingly hot. Who rides out to race a bike at Bonneville . No one except Bryan, Nick, Mark and Brother Speed. Rolling Thunder.
Pits Bonneville Salt Flats
Before you can move in and set up your pit you have to go though the complete registration process with the SCTA-BNI which includes a vehicle technical inspection i.e. if you aren't legal then you don't set up a pit. Bring all sorts of money and medical forms. Actually it's the cheapest motorsport on a fee basis you will ever find.
Why is the Bullett in the pits and on the salt? Well it's because of Diana Sterk. Herding hard core Bikers is akin to lassoing feral cats in the darkest beer bar in the middle of a tornado...Not the easiest task. A businesswoman, she organizes the benefits, the social media and keeps the team headed in more or less the same direction. It takes money, resources and organization. Raising money to help wounded vets who were double amputees is not something the average person sets out to do. Diana is not your average person.
Maintenance after testing...new spark plugs, battery charging, cleaning salt off the intercooler, reprogramming the Pectel SQ6M engine controller and making safety checks before you put the bike back in the line.
The salt and track conditions were really bad with ruts in the soft salt...akin to high speed slaloming on snow with the occasional rut that took Bryan on an unplanned journey from the right side of the track to the left side of the track at 190 MPH. Hey, we came here to test the systems and the track wasn't going to be a 250 mph hard surface with good traction. The car guys came up and said you must have to have the biggest balls on the planet to go 190 to 200 MPH on two wheels on this track given the conditions. Many car guys went home after one run. Even the offical that dragged the track damaged his car on the rough course.
Brother Speed's Mark and Shane button up the Bullett for another run. The canopy must be removed for spark plug access. Bryan can sit in the air conditioned cab of Walt Hennig's diesel truck to avoid roasting in his leathers.
Mark secures the
"Alligator" pad that Bryan rests on at speed. Beneath it are 3/8" thick
aluminum plates. The whole Bullett weighs 1000 lbs.
Casey cleans Bryan's face shield. Better in the pits than on the start line.
Red Bull at Bonneville
Way more than 30 years ago
we used to say when racing... "The only women you are going to see will
be tacked to the wall with the staples removed"...Bonneville is the new
exception to this rule. Diana scored a load of Red Bull for the team.
Party...hold the Salt.
Diana brought the crew food while we are waiting in the line.You wait a long time at the beginning of SpeedWeek and, as the days go by, and people leave or blow up, the lines get shorter. This day it was a long wait.
Mark and Walt...Sometimes
there is a spin on the course, a blown motor and debris on the track,
or even the wind comes up too strong and everything is put on hold.
Time to look at interesting iron.
When you get six to eight vehicles from running, we unload the bike and keep advancing it in the line. If you aren't ready when you are supposed to be it's back to the end of the line. Notice the exhaust burn on the fairing.
You are the show at this point. The whole Bonneville world stops for you to do your thing...Isn't that a bit strange in todays world?..i.e. People politely waiting for you to have your moment without intruding.
George: Lawyer..Vintage Bike Club President, Racer, Bullett Starter
George, in the white uniform, absolutely loved the Bullet and we asked if he would like to be our engine starter. That involved actuating the solenoid when all electrical systems were armed and it was time to race. Bryan would give the nod and George would start the Bullet. Like all racers he did his job perfectly. Try that at Indianapolis or F1. Class act.
I was going 190 MPH
and the bike went sideways!
Course on hold and Bryan discussing Bonneville adventures with a Red Hat 200 MPH Club Member.
Off the Salt
We took the Bullett back to our $3,500.00 worth of motel rooms in Wendover to get beer and make adjustments to the Cosworth Pectel SQ6M Fly-By-Wire system after our second run, during which the throttle went into failure mode which was programmed for a 14 degree fixed opening, a fast idle. If you make assumptions you may turn out to be on the ass end of things. We assumed two Bosch 60mm FBW Throttle bodies would be the same. They weren't. In that the Pectel SQ6M FBW system has 167 programmable functions there are all sorts of safeguards built in. Small variances in the dual potentiometers caused the throttle to close.
Simple fix if you know how.
For Tomorrow We Die
Eat Drink and be merry for.....Party Time.
Back on the track...Fly-By-Wire reprogrammed..194 MPH
At 5600 RPM the rear wheel
was going 260 MPH and the bike was 194MPH on the GPS Speedometer. Bryan
was all over the track in and out of the throttle, throwing
of salt. We were running the Pectel programmed boost control which
specific boost values by gear and throttle opening. Here the bike hit
2.3 Bar or about 19 PSI of boost. We made two runs where Bryan hit over
190 MPH but the course was rutted and there wasn't much in the way of
traction with Bryan plowing through soft salt and bouncing through the
ruts at these high
speeds. The ruts would take him all over the track. We learned a lot
and have ample power, in this case, about 380 HP @19 psi and 5600 RPM.
Nothing was hurt and we wait to see if the next events will offer a better track.
Back in Boise...Clean Up
Back In Boise at the Brother Speed clubhouse. Hoses and pressure washers with various openings like the turbo masked off. Shane and Bryan washing the Bullett.
Shane...working his ass off
at Bonneville and also back at the Brother Speed clubhouse. The Salt
eats everything. It's slowly been eating the trailer but we're still
good to go.
Bryan blow drying the Bullett with it resting on the Mike Geokan designed winches that elevate the bike and keep the tires off the ground.
Ready to roll at the next event with the Pectel SQ6M Seven Position Traction Control fully implemented.
Red Vehicle Pass for Pits. Red Arm Band for Crew. Only one yellow arm band. Button for Crew. And a stack of credit card receipts.
Poster Seen at Wendover Post Office
Nick Arias III (Arias
Pistons) was an official on the starting line. He said we seemed to be
having a lot of fun even getting ready to run. We did. Brian has the
yellow arm band and that got him the best seat in the house at 194 MPH.
It's all Rock N Roll.
Big Dogs, Factory Dogs...Big Money Nonetheless
Poteet and Main Speed Demon. New car after crashing the
first one. 420MPH. Tufts on tail were photgraphed at 400 MPH...The aero
worked. Kenny D and Shane T.
Tiny 3 cylinder motor. Honda Factory effort. The rising sun near where the Enola Gay trained. Time Time Time...Honda is a racing company.
2016 USFRA World of Speed 10-13 September
Headed for USFRA tech inspection. Diana Sterk usually has her Canon cameras on the ready, shooting pictures and videos when she's not herding Bikers, coordinating hotel reservations, or running her business. Hell of a photographer. Bright spot on the great white.
To view Diana's photography see below:
You Tube Photo Compilation
USFRA Photographer stopped
by while were waiting in line to tell us how much he loved the Bullett.
Hand made craftmanship in the Bonneville tradition of Sir Malcolm
Campbell and others. We also had a couple from Geneva Switzerland stop
by...Heard the wife speaking French so we asked in French if they were
French..."Non, nous sommes Suisse....de Geneve"...Heuresement nous
parlons Francais. Small world. Genevois a Bonneville.
As you near the start..Here we are about 8 vehicles from our turn..We unload the Bullett. The trailer tilts and Nick Stock sits on the Bullett while Matt Torres guides him down the bike ramp.
Shane and Diana. Sunglasses
and sun block. Bullett headed for the Long Course which is timed
between the 4 and 4 1/4 mile. By the 5 mile marker you were supposed to
be shutting down and there was only a drag as far as the 6 mile. The
salt was thin, but hard, and there were some muddy spots where the salt
had broken through. Bryan and Nick Stock drove down the course to take
a look at it. Monty, the USFRA starter, asked all competitors to drive
their passenger vehicles and trucks down the course before the actual
meet started. The idea was to let people decide if they were going to
run at all and, most likely, what plan of attack they would have on the
Nearing showtime. Umbrella to keep the sun off the Bullett's seat.
Time to roll. Nick Stock
sinches up the D-rings on his dad's helmet. Blue arm bands are for crew
members. Shane and Matt keep Bryan and the Bullett in the shade, and
Mark secures Bryan's leathers. Mark starts the bike when were are given
On hold at the start as the three mile timing light malfunctions. There was a long wait in the hot sun in black leathers and a helmet. Way, way, long.
Crew members like Mark,
Shane, Bill, Matt, Wino, Casey, Nick, Diana and of course Bryan, the
Bullett's driver...all leave things on the plate to go to
Bonneville...bills, obligations, relationships, shutting down
businesses, skipping medical appointments and so on. Alternate reality
in a strange land. Brother Speed.
Bryan was about medium rare in the long wait, so we had him remove his helmet, and Diana applied a cold towel to his neck to cool him down.
161 MPH, Third Gear, Salt Good, Watching the GPS and Tach, accelerating..Then
Bryan was accelerating in third gear at 161 mph, settling in to attack the 4 to the 4 1/4 timing lights, and he heard a loud noise and felt a loss of power so he vectored off the course slowing to 80 mph with the engine still running. He stopped and the engine was idling at our programmed 1300 rpm and a USFRA Course Official pulled up and saw oil coming out of our rear breather vent and told Bryan to cut the motor.
Back in the pits Bryan started to pull things apart to see what was what. We pulled the spark plugs and they were OK. We
then checked compression in front and rear cylinders and it was 175 psi
in both. Next we checked our four top end breather lines and they
dry. We then checked the dry sump oil bag and it was nearly empty.
Bryan started dissecting the oil pump as there was no scavenging and
our jackshaft driven vacuum pump pumped the oil out of the lower end.
Bryan removes the S&S Billet Oil Pump after finding some unknown debris in the bottom of the camcase.
Oil pump removed with damage to the gears and shaft. One scavenge gear cracked when it injested something. Brass valves and fittings are part of the jackshaft vacuum pump setup. Visible are the watercooled cylinders. Stainless steel merge collector to the turbo with ceramic coating. Jim's Fat5 transmission.
This circlip on a seal from the second bearing on the Pinion Shaft facing the cam case came off and took out the oil pump, shearing the key in the drive gears. The lower end filled with oil and slowed the motor and our vacuum pump, driven by the jackshaft, pumped the lower end out the back. Stupid fkking bearing that was put in won't be going back in. No way to fix this. Motor has to come apart and a more logical bearing be installed. Shame because we had a workable race surface due to all the work by Monty and the volunteers of the USFRA.
This is the Bullett's jackshaft-driven vacuum pump
which is connected to the upper and lower ends of the 139" motor. It kept
pumping when the the S&S Oil Pump drive keyway was sheared. Hard
anodized to keep the salt from eating it. No debris got to it.
Nothing to fix so we headed for the Hotel rooms
for beer, Vodka shots, controlled substances, and a Buffet Dinner.
Planning for 2017 begins. It was a good time nonetheless. Great people
and friendship. Another adventure and no one went to jail in Elko this time.
Bryan came home safe which is the most important thing of all. People have
died there recently.
Artifacts Circa 2016
Lucky Buck, 1 Free Drink,
Vehicle pit pass, personal pit badge, crew wristband, pile of credit
card receipts....stuff for the archaeologists to figure out the
religious or ritual significance of in the future. What motivated these
people to travel to this desolate location and give offerings to some
strange deity? What secret rituals did they perform and where did they
come from to begin with? No bones were uncovered. Where were their dead
buried?...All questions which are unanswered. They seem to have come
from many directions. How did they communicate to arrive at the same
time each year? Were sacrifices performed ?....They left straight blue
lines leading to a floating mountain.
Post 2016 Bonneville: Time for New Tires
set of these Goodyear LSR 300 MPH tires was used for the construction
of the Bullett. They became weathered during the long build process and
were cut in half for close inspection of the thickess of the rubber at
the request of Nate Jones Cowboy Tire. Shaving excess rubber was done by Nate
Jones to balance and prep the new tires and to round the front tire for
better handling. This second set was used for the initial running,
gaining licenses for the Long Course, and setting a 200 MPH Record that
stood for 5 years. After spinning the rear tire at over 260 MPH,
bouncing through some deep ruts at 194 MPH, and plus the effects of
weathering, we decided to put on new rubber for safety reasons. You are
looking at $1650.00 worth of new rubber. Our third set. Does get
Bullett is about the only long course (>175 MPH) motorcycle that
actually has legal tires in the eyes if the SCTA-BNI Bonneville
Inspectors. There have been crashes at Bonneville due to tire failures,
and numerous instances of tires chunking with Z-Rated tires running
well over 200 MPH. Motorcycles have crashed and people have died in
other Speed Events...Perhaps with tire failure as one of the factors.
Mike Geokan, some 24 years ago, made the decision to design his Bullett around tires that would be safe. He had no guidance and he was on his own. He was proved to be correct. 45 degrees of rake, a stiff chassis, a long wheelbase, and safe tires to bring the rider home alive.
When you stick a 560 Hp turbo on the 139 CID Bullett Orca Motor the pistons, piston pins, and rings get subjected to a lot of heat and pressure. A lot of people ask what we run and here are the specifications: CP Pistons 4.367" for a 4.375" Bore; Top Groove 0.064"; 2nd Groove 0.064"; Third Groove 0.149". Flat Top with relief for the 2.200" Inlets and 1.800" exhaust valves; 0.927" heavy wall pins with 0.073" wire locks.
cut the skirts for clearance and ceramic coat the piston tops and
graphite coat the skirts. Ring gaps are 0.026" for the Top Ring and
0.028" for the Second Ring; Std 3 piece oil ring. No cylinder head
gaskets or base gaskets with Silver-plated Inconel 600 psi Nitrogen
seal rings on the cylinder heads. We have even run PEEK Buttons on the
skirts. Drop $2,500.00 on the pistons...and more on the machining and
coating. We have had zero issues running high zinc content Brad-Penn
139" Orca motor has been used as a test bed to experiment with new
technologies...electronics, closed loop boost control, traction
control, bearing designs, piston sealing, vacuum pumps, ceramic
coatings, high temperature valves, cylinder head porting, camshaft
design and more.. Somethings have worked and somethings have failed. It
is definitely not short on power as Bryan Stock can attest...His first
words after a 214 mph run...."I want one of those in my Dresser!".
