I noticed that some of the drag times for the modified (Naturally-aspirated/bolt-ons only) Mustangs were actually worse than or equal to those of the completely stock 'stangs.[sm=smiley5.gif] I was wondering why that was? Could someone explain why this is?

when you start modding the six it doesn't take long for it to get too peppy to launch on street tires without plenty of experience. They spin bad in first with light mods until you add either drag radials or slicks or a tlok or lca's.

You'd have to show me some examples to better explain what you mean. Stock, the 4.0L V6 typically runs the 1/4 mile in about 15.0-15.5, whereas modded NA 4.0L's run high 14's to as low as 13.8 (depending on the number of mods). Plus, some cars are just faster than others because the production gods blessed that combination of parts to work together better than the next car on the line.

I think what you might be seeing is variances in tracks across the country. Those at high elevations will be slower than tracks at sea level. Atmospheric conditions (heat mainly) also affect track times. And the tracks themselves are different, with some being faster due to design, slope, electronics, etc. Although 1/4 mile times are the yardstick by which performance is measured, variances are at play here. The same applies to dyno numbers too.

I had just been looking at the forum official drag times, and the numbers seemed low to me, when compared to the unmodified 'stangs. Thanks for the clarification!
