Pujo! attacks the track! Then the track counter attacks...

Pujo! finally got a chance to see what a real race track is like. Sadly only I was able to see what Pujo! is like on the track. Initially everything seemed pretty good, but I became concerned about a distinct lack of power. Handling is nice and neutral, braking is excellent, but the power just wasn't there. After about 15 minutes I noticed the temp gauge start to climb, I reduced my speed to right around freeway speed to see if it would cool off, and it did for about a lap, then it began to climb again. I wasn't overly concerned but through my ridiculously padded and insulated helmet (I'm rendered effectively deaf in the damned thing) I began to hear an alarming rattling sound from the engine compartment. Right about this time a '64 Mustang with a dry sump ruptured a line and dumped about 30,000 barrels of oil on the track. Fortunately I'd already slowed to about 30mph by the time I reached the Mustang Valdez oil spill and stayed on the track. Sadly the same couldn't be said of an Acura and an E30 (S**t, those things are friggin' everywhere) some sea otters and about a dozen arctic terns. Once I'd passed the environmental disaster and climbed the hill back towards the paddock, Pujo! decided he'd had enough and passed out by the side of the track. The radiator overflow then boiled over and clouds of steam billowed from beneath the hood. I tried to restart to keep coolant flowing but Pujo! refused to wake up. Once we rolled him back into the pits and gave him a chance to cool off, he restarted normally. Except for the disturbing rattling noise. We figured at that point we had a bad connecting rod bearing. I was glad we brought the trailer. After a 2 hour delay while hundreds of volunteers scrubbed the otters, terns and track with loving hands and Dawn liquid dish detergent, we finished the rest of the day in Bret's Miata and Brent's M3.

The next day Scott and I got to work on Pujo!. Embarrassingly the overheating appeared to be caused by an improperly burped cooling system. There was plenty of water left in the overflow bottle, but the radiator was several inches down. Since I was the last one to drain and fill the thing, the blame rests squarely on me. The lack of power turned out to be from a crack in the accordion hose between the MAFS and the turbo. Most cars won't run at all if that happens, Pujo! simply gets tired. Luckily, the old black car (remember Pugly from way back when we started all this?)had a good one it wasn't using any more. What about the alarming rattle from the engine, you ask? We pulled the oil pan and discovered the chain driving the oil pump was loose and could clatter against the timing chain cover. Thankfully all really simple and quick fixes.

Pujo! lives to drive another day.

Ha! Suckers!

We're taking Pujo! to Pacific Raceways in scenic Kent WA for the Northwest Alfa Romeo club track day on the 23rd. While I was signing up I noticed the "tech form" link. This tech form must be filled out by an ASE certified mechanic. Uh-oh, I thought. So, rather than click the "unregister" button, I figured what's to lose?

Last Friday I drove Pujo! to the nearest ASE certified shop and handed over the form with an explanation of what the car was built for.

"Really." said the man behind the counter "An endurance race for $500 cars? You mean like a demolition derby?"

"Well, I hope not." I replied "Anything short of a Caprice Classic is going to get seriously injured if it hits this thing."

"Ooookay..." said the man.

Seriously, this car has been rear ended harder than Elton John. Rolled, dropped, lifted by a giant forklift. There's Bondo on the roof. I personally do body work on it with a sledgehammer because any lesser tool just isn't sufficient. This thing has survived situations that would make Superman squeal with terror. A Honda or VW would just bounce right off and not leave a mark.

But, I digress...

After a short wait a nice young man named Carlos took my keys and headed for the parking lot. It took him a moment to figure out how to get in over the anti-intrusion bars. He even put a nice, clean paper floor mat on the floor. Two other technicians looked on in disbelief as Pujo! rolled into the shop followed by a subtle cloud of blue smoke. Soon Pujo! was up on a lift for all to see, displaying more evidence of past impacts than your average moon.

Carlos looked at the damage and said, "You race this, man?"

"Yes. Yes, I do." I said proudly.

He looked again at the crumpled floor pans and wrinkled frame rails and then looked at me as though I were obviously dangerously insane.

"F--k.... you're crazy, man." He said, shaking his head.

"Yes. Yes, I am." I said proudly.

Rather than argue with me, he signed off on the car and sent me on my way.

I hope the Alfa guys have a sense of humor.

Pujo! looses his racing virginity

We took Pujo! out some development flogging at an autocross event in Bremerton.
He's such a sexy beast!


We found the handling to be surprisingly good tolerable and at no point did we scrape any of the door handles on pavement. We did, however, notice a bit of rubbing still happening on the back wheels. They make a loud screeching noise when cornering hard. More sledgehammer and cutting work is called for in the rear.
Right full rudder!


This was a unbelievably freaking cold weather event - yes, that is snow in the picture below. It was part of the WWSCC's Winter Slush Series and you can see that we didn't do too poorly. The inconsistent times tell the tale of intermittent fuel delivery, intermittent electron flow, and screechy tire to fender contact induced throttle lifting. The little penalty numbers? Those speak to driving mistakes.
vroooom pop...putt putt pow vroooom

As regular readers of this blog [are there any?] know, we Cheese Eaters are not big fans of snow. This event allowed us to, as they say, get back on the bouncey, unstable french POS horse.
Freakin' snow, always messin' with our shit!.


Our horse showed off its Franco-Bastardly nature by starving for fuel at inopportune times. We believe the fuel pickup in the réservoir d'essence gas tank was bent in the trailer tumble into the ditch on Christmas Day. A frightening drive to the second nearest gas station temporarily resolved the starvation issue. However, we still had myriad a few electrical gremlins interrupting our combustion events. We enlisted the aid of an English driver to assist in sorting some of these issues. Some say his nipples are positive ground points and he speaks fluent reverse Swahili, all I know is he's called the Stig.
in this case, le Stig.


Now that the first event butterflies is out of the Pujo!'s system, we are looking forward to tuning him for endurance racing success. Team Captain Sean is on top of things and leading the way.
Crossing the Alps on a horse is for wussies, I'm riding a lion!
