HSMS HAS ROUGH OUTING
AT BOISE Engine Damage Takes Green Out Early
August 04-16-2009
- Boise, ID - The
38th edition of Firebird Raceway's signature event was a weekend
of way below normal temperatures, huge crowds, record runs, major
upsets and lots of drama. The Nightfire Nationals are Idaho's
premiere motorsport's national championship, and the 2009 edition
was even bigger and better than any year previous. Headlining
the 4 day show was Top Fuel Dragsters and Nostalgia Nitro Funny
Cars. In spite of a grim economy, there were 32 nitro cars on
the grounds and both the Friday and Sunday crowds were bigger
than years past. Most credit the absence of the normally hot
weather for much of the increase.
For Troy Green
and the HSMS team it was less than a good weekend. Historically
the gang has not had much luck at Boise. Unlike Bowling Green
and Bakersfield, Firebird Raceway has not been conducive with
Brett Johansen's tune ups. This year was no different. After
crossing the centerline in his first qualifying attempt, Green
did manage to qualify 6th on his next. But a 6.11 was far off
the pace needed to go rounds.
In years past,
there were three pro qualifying sessions but in an attempt to
give their largest crowd (Saturday) a better show and have first
round of eliminations under the lights they dropped one session..
So, session two was the last chance to nail down a tune up and
jockey for a position on the ladder. It also left the team with
a tough decision that in hind site turned out to be the wrong
one.
Said Green, "To
say we're disappointed is an understatement. We were behind the
8 ball all weekend and things never came together. We'll go home,
regroup, assess the damage and do better the next time out."
Team Manager
Tom Shelar was more direct. "Boise was about the worst outing
that I can remember. We need to get back to a baseline that we
had last year where we could run a 5.80 on any track."
Virtually out
of the points chase, the team will run the Pinks All Out show
at Bakersfield September 12 and pass on the Hot Rod Heritage
race at Sacramento on September 18th. Shelar stated, "We
will not be going to Sacramento. It is better to spend the time
and money on the car and another test session if needed before
the CHRR."

Fuel Qualifying - Session One
Being the last car of the session,
Green got the whole track to himself... and he needed it.
The car was very sluggish
at the hit... the clutch way to soft.
After a terrible 60'
time the car started to drift toward the center line.
Out of the groove and got on
the unusual asphalt strip between lanes Green tried to steer
the car back.
In a heartbeat the clutch finally
locked up and literally tossed the car into the left lane,
Fortunately there was no other
car on the track or this could have been ugly. Said Green, "The
car moved so hard, so fast I couldn't do a thing but reel it
in when it stabilized."
Saturday - Qualifying
Session Two
Green would once again
make a single run.
Once again the car was
very soft at the hit of the throttle.
Another lackluster 60'
time but the car was going straight.
In spite of drifting to the right
this time the car did not make any violent moves to the other
lane.
Staying in his own lane Green
clocked a mediocre 6.11 at 235.54 to land in the #6 qualifying
spot.
Saturday - Eliminations
- Round One
Round 1 was scheduled for 7:00
but actually got underway about 7:45. Green was paired with Mike
McClennan in Mike Fuller's "Forever Young" car. McClennan
had lane choice.
The car was more aggressive on
the bottom end and promised to give the blue car a good race.
At this point Green was hanging
in with McClennan but once again slowly sliding out of the groove.
At this point Green was dangerously
close to the wall but it didn't matter - the engine was a dead
player.
Then the engine burned the #
7 piston and debris from the piston got stuck under the # 7 intake
valve. When it blew up, the # 7 intake valve was not sealed to
the seat letting the ignition spark the fuel into the manifold.
When # 7 is on it's power stroke # 4 is on overlap. The explosion
in the intake manifold blew the # 4 intake valve into the # 4
exhaust valve and that is why the # 4 valves were broken and
the chamber and piston in the # 4 hole were beaten up. Got that
so far?
The good news is the Manifold
designed by Tom Shelar performed exactly as it was designed to
do in this situation. The explosion in the manifold was so big
the burst panel area was insufficient . The manifold is designed
to split if the explosive energy is so big that the burst panel
area and the blower shear studs are not enough to allow the energy
to escape fast enough. ( Scott Kalitta's 's manifold exploded
opening up the engine valley, Mendy Fry in Frank Hedge's car
at Sonoma had the same issue both resulted in a big fire.) The
only fire Green experienced after the initial explosion was a
small amount of oil from the oil pressure gage being damaged.
And they did not put any oil on the track just a small amount
of nitro from the fuel system. Boise Boom
We apologize for the quality
of a couple of these photos but they were obviously shot in low
light and pulled from a video camera.
Oiled in, Green did a masterful
job of keeping the car off the wall and in his lane.
As Great White limped along McClennan's
ride had problems of its own. The ensuing oil down led to a 52
minute clean up and delay running funny cars. There are many
good things to say about Firebird Raceway but their speed in
doing track clean ups isn't one of them.
