How accurate is that analyzer?

[AJSTANG]

It seems like the analyzer is accurate if you use car weight without driver and rear wheel horsepower.

Tom: For example an 89 LX in stock form is 3050-3100 lbs. Rwhp given a 15% loss in hp would be about 191. Plug these numbers into the analyzer you get 14.67 @ 92. These are typical numbers for a stock LX.

Now your car in current form with rollbar, supercharger and aftercooler is closer to 3200 lbs. Substituting 3200 lbs and a trap speed of 128 mph gives 462 and 523 hp. Using the higher hp number (523 and a weight of 3200 results in 10.65 @ 127. Your 11.1 was with DOT slicks; with ET drags you'd have a 10 sec pass. So the analyzer looks fairly accurate in my opinion using use car weight without driver and rear wheel horsepower.
