    Met up with Pokey today for a short blat. The rolling pylons were particularly bad, although strangely only of the motorized variety. Typically this route is full of bio-powered pylons whose idea of sharing the road is to ride 3-abreast in the lane and force you to either risk a fairly blind pass, or settle in for a 25mph drive. As we approached the base of a particularly fun uphill section before the turnaround point, the Blat gods smiled upon us and the traffic finally parted. Woo hoo! With over 400 miles on the engine, I'm starting to use a little more throttle and revs.

    To celebrate the engine breaking the 500 mile barrier today, the break-in oil was swapped for 5w-40 synthetic per SBD's recommendation. This appears to have solved my low oil pressure issue at hot idle. During the subsequent test drive, I made a brief foray into higher rpm, hitting 6500 rpm in second, and using *maybe* 3/4 throttle. The engine feels like it's getting into its zone over 5000 rpm, which is what I was after. Although the plan is to leave the safe, starter ignition map alone until the car gets on the dyno in a couple of weeks, I may do a little data logging in the morning and make inroads on the fueling map at heavier throttle.

    I finally had time to do a little data logging and tuning this morning. On the way home from the baseline run to establish how far off the current injection map is from target, I caught up to a beautiful Miura S that had turned down my street. It's one of my favorite cars, so I carried on past my driveway and followed him for 5 miles until he turned into the local supermarket. We had a short chat after which the phone came out and pictures were taken. (cue Mike or Sean to make the obligatory Stalker joke )

    Had a bit of a concern though when leaving the lot. I nailed it down the access road that leads to the main road, but as I approached the stop sign and threw in the clutch, the engine switched off. It fired back up immediately and continued to run flawlessly, but that's a potential concern.

    The map was unsurprisingly lean, so after looking through the logs I made some changes and headed back out. Much better, and according to the subsequent logs, much closer to target. Taking the car up to 7500rpm revealed it has exactly the character I was after. It reminds me of an old 911, just a hell of a lot faster. No sudden feeling that the engine has come on the cam, rather a relentless increase in power the higher up the tach it goes. Can't wait to get this thing on the dyno to dial in the timing and optimize the injection map.

    John, In 1968 while going to school in Santa Barbara, CA, a kid that lived in the private dorms (Francisco Torres) we lived in Isla Vista, was loaned a Lamborghini Miura S as his "school" car for a short while. The rich little so and so was clocked at some incredibly high speed on the road leading into UC Santa Barbara and a California Highway patrolman gave chase only to lose the kid in our small town. The story goes that the driver and his companion drove into the first open garage in IV, closed the garage door in an attempt to evade the Highway Patrol. Someone called the cops and you guessed it, that same HP officer responded to the call and arrested the two kids.

    They both went to court for something like reckless endangerment or some such thing and the judge sentenced the two students to something like 2 months of weekend lockup so they could continue to matriculate in school. The passenger reportedly complained to the sentencing judge that he had not been driving and reportedly the judge had admonished him that he could have turned off the engine and thrown the keys out the window to stop the recklessness so was guilty by association and inaction. I fawned over that Lamborghini as I only had a lowly red 1964 Triumph TR4. Long story short, I think that the family took back the Lambo and that was my first close up regular contact in the parking lot, on a regular basis for a brief period of time, with what turned out to be one of the first supercars ever put into "production". 12 cylinders of handmade beauty was that engine (3.9L V12).

    Of course, growing up in Southern California, if there were 7 examples of any truly exotic car in the USA, usually 4 or 5 of those examples would be in Southern Cal. It was an amazing time in the burgeoning era of supercars. I was lucky enough to run a Country Club parking lot and the nightmarish stories about lot workers going on joy rides was not completely a myth The only thing is that I didn't realize that some of the original Cobras and other exotics I was parking would become multi-million dollar pieces of rolling history.

    Bob, I used to live in SB. By any chance are you referring to Ward Memorial Blvd? For the rest of you, it's effectively a freeway with no onramps for quite a stretch. Perfect for high speed testing. Not that I ever did that...

    I was taken for a spirited ride in '67 Miura back in the mid 80's. I still remember the howl of the engine as the car approached redline in third gear, and the sight of the triple choke Webers filling up half the view out the rear window. Good stuff!

    For a rare exotic car, it's amazing how many of us have some story connecting us, if briefly, and tenuously, to the Miura. I was a senior in college spending my last quarter of college "studying" abroad, in Italy in 1968. I came around a corner in, I think, Florence and there was a Miura parked between all of the plebeian Fiats and 3 wheeled Piagio "trucks". Time stood still. It was about as low as a Caterham and as wide as the Ohio river, or so it seemed. And the presence and stance and electric neon green color made it such an indelible memory that here I am, 52years later, remembering it like it was yesterday.

    Remember indeed. At the Mexican Gran Prix, 1968 ? The "official car" was TWO white Miuras. I suspect they belonged to the Abed brothers, but who knows. Every time they went around, it was like a low altitude pass by an F-1 car. Wow!

    John, It was likely Ward Memorial Blvd. I never talked with the driver of the car that got caught so my understanding of the story came from hearsay of some of the other IV residents at the twin towers of Francisco Torres that UCSB subsequently purchased and expanded into a 19 acre site. I do know that some of my friends at the time devised a scheme to turn on and off the lights of one of the buildings so that the letters spelled "F*CK" about 7 stories high. It stopped traffic for hours around the building as word got out of our prank. I learned to pick a simple lock during that time but was not much of a participant in the final act. An old high school chum that became an attorney was part of the cadre that pulled off that very funny stunt. IV was a hotbed of learning and excitement along with antiwar protests. Famous folks like Andy Warhol hung out in IV reportedly in about 1969. I was getting so off track and flunking out of school that I returned to LA to get my head right to continue on with college. They were certainly fun times playing in the sand dunes of Devereau School on the Pacific Ocean. Some of my group would get pretty stoned at the time. Thankfully, like Bill Clinton, I never inhaled.

    Kitkat, many of us have only had 1 or 2 degrees of separation from many really cool events and people. I suspect that many of us that have been drawn to seven cars have lots of stories of the very interesting people and events we have experienced along the way. It is that sort of yearning for adventures that lead us to sevens and other fun machines and people.
