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! :)

That isn't an A/F gauge to the right of the steering wheel?

[zredbaron240]

It is, but it's nonfunctional. This was literally within 24 hours of assembly, and there was no exhaust pipe (or bung for an O2 sensor). No sensor, no data. I just used my butt dyno.

Awesome!!!!!!!! What has been done to the chassis and suspension?

[zredbaron240]

Chassis - strut braces, carbon fiber hood and hatch.

Suspension - Koni yellow 2-way adjustable race struts, 350/300# front/rear springs, heim-joint mounted and fully adjustable front sway bar (no rear bar due to 4.37 Quaiffe ATB R180), camber plates, steering knuckles, bump steer spacer.

Please tell me what kind of ignition set up that is. That is sweet and clean...

[zredbaron240]

Electromotive XDI. Highly recommended. :)

[zredbaron240]

Absolutely not. E85 is not a performance fuel. From Wikpedia: "Another drawback for E85 is that, in a liter-to-liter comparison, E85 has less energy content than conventional gasoline; 30% percent less energy for transportation by volume." This is why fuel economy and horsepower outputs are both worse on E85.

Such a beast of a machine.

Did you notice a performance improvement with the stahl header and how did it change your exhaust sound? louder?
