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! :)

280Z Triple Weber 45 - First Start
UPDATE - After 3 months of light use, this engine failed. The rockers kept coming off the posts, and eventually pistons made contact with the valves. 3000$ engine down the drain... stay away from ebay rebuilt engines! New Rebello 3.0L has taken its place - See my other videos.

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 redline.
