Do keep in mind that when this baby came out of the assembly line, back in '94, all of its young muscles could only muster a mellow 7.8 sec. 0 to 60, according to Jaguar. But now, when tested with all of the features ready, this baby reached 60 mph in only 5.2 seconds, a truly impressive reduction of 2.6 seconds (a whole 1/3 drop) on this, the most popular of acceleration tests and actually a match to the S/C newer V8's. The Unexpected: This is pure magic. Normal driving is radically transformed; a real joy! To make the car more responsive and lively without using full nitrous, I've developed a system that provides a controlled, very short 0.5 sec "pre-push" that starts the very moment that the gas pedal reaches 80% (not WOT on this application), which is enough to sharply reduce the time that it takes the engine to spool up to its best power producing rpm's. The duration of this pre-push (that I choose to keep set at 0.5 sec.) is adjustable from 0.2 to 1.5 seconds (little knob next to the fuel press. gauge). When set on this mode, the car will respond much quicker and only if you ask for it (i.e. you do go to at least 80% gas pedal travel). This, radically transforms the car's behavior because the usually slow rpm build up becomes an instant rpm build up (how's 0.5 sec.), from which point on, the engine, which is already flying, takes over in a purely normally aspirated (NA) fashion, making it really sporty, responsive and fun without having to be flooring it. The beauty of this is that the short duration of the pre-push makes the bottle last forever and, if you do the math, this comes at an unusually low cost (very low N2O consumption) for what you're getting.
