elevation question

tlrmax · 10-25-2003, 09:20 PM

How do you figure out what a run will be with the elevation at sea level. My fastest time is 15.8 at 94mph. I have ypipe, greddy , race pipe, and cai with a 5spd 99 max. I raced a couple of different taurus sho's and I beat them at the track. They do 16.0. Z28's do 14.5-14.9, mustangs do 15.1-16.0.
What would my time be at sea level?

The conversion table I just found says .9523xET to get your "corrected" ET and 1.0507xMPH to get your "corrected" mph. I would multiply it but the calculator on my computer is broken for whatever reason and my graphing calc is out in my car and it's cold out. Don't put too much stock into your corrected ETs and compare them to other people's ETs on this board, because no one here runs at sea level except maybe the east coast guys.

Your corrected ET is about a 15.0. Your corrected MPH is about 98.5mph which is pretty much impossible with just an intake, y-pipe, catback, test pipe. I have a feeling your track use the old school method of using the true ending MPH in the 1/4 mile and not the average last 60' of the 1/4 mile. Some tracks use the new method and some use the old method. It really doesn't matter because it has no effect on ET and that's what really counts. With the new method of MPH calculation your MPH would be around 95-96mph which is believable. If you ever get a chance and you're in Houston, go to HRP. It's a very quick track and actually sits a few feet below sea level.
