Do you think a V-AFC would help on hp and safty?

I sold my 95 NSX to get a S2000 and I would like to make it faster than my NSX. Do you think I would be satisfied with a S/C?
Satisfied? I recommend you test drive one first. I love my supercharger and couldn't imaging driving the S2000 without one.

No. A VAFC can take away fuel. It's not so good at "adding" fuel and on a blown car, this is more likely what needs to be done.
But it helps your power and be more in the safety margin. Dyno proven on mine.

In addition to above questions, what is an acceptable A/F ratio under boost. I have the AEM A/F Gauge and under boost I am running about 13.5-14.0. Out of boost I am running 14.6-15.1
Are these acceptable numbers? Vortech stated that with my Mugen header the car might be running leaner, but I haven't see that.
Those with gauges what are your numbers?

WOT? What does this mean?
Also should the A/F numbers stay the same from 6200rpm to 9k (I have the same gauge as you xviper)?
Finally, anyway to adjust the richness of the engine without an AEM ecu?

It should be pretty steady once the throttle plate is wide open even from lower rpms but especially during the upper rpm range.
You have a Vortech, right? You can alter the a/f a bit by upping the fuel pressure. However, the Vortech FMU is not easily adjusted (unlike the Comptech which only requires turning a screw). You have to take it apart and put in the appropriate part inside that will increase the fuel pressure. It's an educated guess at best and you can get the parts from Vortech. I've never had the need to do this. Perhaps someone who has, can post here and tell you what's involved.

WOT = Wide open throttle
the AF's on a stock PCM equipped car will vary greatly on a wideband when the PCM is operating in closed loop. You'll see 11-17.1 as a normal range. Once you're in VTEC and at WOT the AF's should stabilize and not vary much. Although with the stock boost Vortech and a header, I'd expect #'s in the 13's
There is no adjustment to the FMU on a Vortech car unless you dis-assemble it and replace the internals to change the rate of fuel pressure increase.
