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! :)
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...
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:
Mustangs for lunch
240z (L28 Triple Mikuni 5 spd) @ Sebring: NASA HPDE3, second session of the day on June 20, 2009.
Starring Gee-Force Z spider :)
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 4-6 weeks of storage.
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 ;)
