Short clip of the race motor idling in Annapolis, MD (summer 2010) a few days before the NE Divisionals (SCCA Solo) in Washington DC.
Cam: .565" lift, 326/315 in/ex duration.
12.5:1 3.1L stroker motor w/ forged slugs.
(Street headers, street muffler, 2.5" kinked pipe.)
3.1L 240Z triple weber carb tuning (w/ new Stahl headers)
A collection of short clips / butt Dyno runs while tuning the
triple Webers on my 3.1L 240Z. Open Exhaust. Unfortunately, I didn't have the
benefit of an O2 sensor / AFR. All in all, I was pretty pleased with the
final results, the new headers have really opened up the head's flow
potential. Sounds good, too! :)
240Z vs. the Ozark Mountains
Some [conservative] horseplay in my 1971 3.1L 240Z before putting my new
race motor away for the winter. This is NOT a performance driving video,
just some fun on an awesome road.
This is first time I've driven the road, so I'm a little more confident
after 3:00. (I found it on Google Earth then trailered my car there.)
Some highlights, since it's not exactly a concise video:
1:55 downhill stretch, crossing Beaver Lake
2:40 more aggressive driving begins
4:00 scared myself a bit
4:40 traffic encountered
5:00 engine vs. open highway
Referenced walk-around video of my L6 motor:
360HP STAR ROAD DATSUN FAIRLADY S30Z WALKAROUND
Come and take a closer look at Star Road's insane L28 powered S30Z Fairlady
that is literally the perfect mix of both the old and new schools. I walk
you around the car, showing you the immense amounts of detail that have
gone into it. It is currently developing a screaming naturally aspirated
360hp, revs to 8000rpm and includes one of the most impressive engine bays
you will ever see including a special custom carburettor/injection setup
that is monitored by MoTec engine management and a full Defi system.
You would struggle to find a better modern take on a classic like the
Fairlady anywhere else on the planet.

1972 Datsun 240Z run. (One last good time before I sold it)
Right before I sold it...
Clicking noise is a leak in the balancing tube (welded day after this
video) Some sloppy shifts due to slack in the rear end and un-adjusted
clutch with cracked clutch arm bracket.
I loved/love this car! So much fun to drive...
untuned and unmuffled idle, 240Z 3.1 stroker
Quick demo of the new race headers (Stahl), at no point does the engine rev
above 3k rpm (despite how it sounds at 1:25). Other coincident upgrades
include titanium valve spring retainers, single valve springs (outer
springs only) that the cam was profiled for, and a crank/damper/flywheel
balance for 10,000 rpm.
And yes, that's coolant on the ground during the idle portion. Evidently I
didn't tighten one of the thermocouple housings all the way. Oops.
Between moving and other logistical challenges, I barely had the time to
get the new race motor installed and minimally operational before sticking
it back in the trailer for 6 months of storage, after which the engine
'71 240Z returns to autocross at the 2010 NE divisionals
First race after weight reduction, new struts/springs and full repaint.
Threw myself into the fire and entered XP at an SCCA Divisional
Championship. Tons of room for improvement, I'll be back next year with
some A6s slightly wider than my current V710s...

Datsun SPL 311 1600 (Fairlady)
By Miguel Caparros
In the early to mid 60's Datsun was the one on the move in the US market
while Toyota was still sleeping. Datsun was taking on the British car
industry head on as it recuperated from WWII. Datsun was one of the
companies that benefited from the leadership of W. Edwards Deming, Who was
chosen by Supreme Commander of the Allied Powers (SCAP) was the title held
by General Douglas MacArthur during the Occupation of Japan following World
War II. I remember the first time I saw an SPL 311 and my reaction to it.
The quality of build seemed much better than the MG, Triumph or Alfa Romeo,
given the fact that much of the technology was under license from US and
Great Britain. As great as the quality of the mechanical aspects were
concerned, the quality of the interior vinyl and plastics left much to be
desire. In spite of that they slowly chipped away at the established
manufacturers with a product of superior mechanical quality and value for
the money spent.
The SPL 311 line finished in 1970 with the Datsun 2000, A car that had to
be taken very seriously as a performance sports car. But it was the follow
up that put the final nail in the coffin of the British dominance, the
Driving impression of the Datsun 1600 from 1968. First thing I noticed was
the size of the car, it felt bigger than an MG Midget but smaller than the
MGB. The controls and switch gear had a quality feel to it and the standard
Am Fm radio was completely integrated into the dash. Also well integrated
was the heating and ventilation levers and switches and they had a light
feel as opposed to some of the British cars that felt as if you were trying
to move a rail road track change lever with a tooth pick.
One stab of the gas pedal and a light pull of the choke and the car started
right up and the choke was not needed after a few seconds and the engine
settled to a smooth idle. The clutch was unusually light as was the shift
the lever. As I took off I could immediately sense that although the
steering was light it did not have the precision of the British rack and
pinion and the ride motion was both soft and choppy at the same time.
Getting on the power made me smile as the little 1600 had power equal to if
not better than the 1800 in the MGB. But it was the great feel of the
gearbox that got my attention. Both precise in movement and light in feel.
Taking it through my favorite set of twisties in Coral Gables It felt good
but not as well planted as an MGB or my own Alfa. But there was no question
in my mind that Datsun had a winner here, specially when you take into
consideration the price.
