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! :)
Triple Weber DCOE's Launch
An old clip of my race prepped high compression L28, during testing with my
45mm DCOE's After a summer of tuning, I determined that my set of 40mm
DCOE's were the best match, and the car was 3 tenths of a second quicker
0-60 with them.
Mustangs for lunch

240z vs Rx7
This was the third session of the day in HPDE3 on April 25, 2010. We saw
this Rx7 zipping around all weekend and finally caught up with it. Both
drivers were testing their limits and it was quite exciting being in the
car and experiencing this "battle" firsthand. Gee-Force Z spider got a good
workout too. Until next time little blue Rx7!

1973 Datsun 240Z, Bahrain
A little vid of my FairladyZ after installing the triple Mikuni Carbs
40phh. She is a 1973 240z with an L28, ported E88 head, Monza Headers,
Shnider Cam, Custom Exhaust and MSD
ignition. It's an ongoing project and more goodies on their way ;)
1970 Datsun 240Z/L28- 7000rpm in first three gears - triple Weber 40DCOEs
Watch for the surprise at the end (!)...didn't get pulled though. See
http://www.youtube.com/watch?v=RjpmkfdnNvI for the same engine with SU
carbs...which is a 1983 F54 L28 w/P90 turbo head, 10:1 compression, 15lb flywheel.
The engines sound similar but the Webers have much more torque than the
SUs, pull very hard in 1st and 2nd and easily to 7,000 in 3rd. I have a
Centerforce 2 clutch now which make changing gears a tick slower compared
to my earlier video however. The car is definitely faster through each gear with solid power to
3.1L 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:
1971 Datsun 240Z Dual SU Powered 2.9L Screaming down the Interstate
This is my "slightly" Modified 71 240Z with bored out Dual SU's and a
2.9LThis Z has run a best time of 12.804 @ 107.26 mph at Rockingham Dragway
on normal street tires. even though it is LOUD, the Exhaust is VERY RESTRICTIVE as it was done with
crush bends instead of Mandrel bends so when I'm at the track I drop the Exhaust with one hanger bolt at the back
of the car and slide it all out in one piece. This run was done with a 3.54
rear end I have 4.11 in it now.
