Anyone know the correction numbers for Englishtown?
Times are in the sig, it was 84 degrees with 64% humidity... I don't know what elevation E-town is at, and I don't know the equations on how to convert it...
Can someone enlighten me?

You also need to know the barometric pressure.
They don't bother with altitude correction below 1200 feet. E-town should be lower than that.

Acording to the Airport next to E-town, the elevation there is appox 55 feet. no need at all to do correction, for elevation.
Englishtown, Atco, and MIR are all under 60 feet of elevation. Making them about the best places to race, you just have to accout for the atmospheric condition for tuning.

Englishtown dragstrip is listed as 60'. As mentioned above there is no altitude correction.
To convert to density altitude you need barometric pressure, temperature and humidity.
If you have all the data I'll tell you what the DA was.

That's very low barometric pressure.
For a track that's at 60 feet altitude the density altitude was 2638'.
17.762 at 76.5 mph. Are you sure that isn't a 4 cyl car? Guessing at 3500 pounds car and driver that works out to 123HP or 127HP corrected. A 2.8 should do better than that shouldn't it. At least 150-175hp

Yes, I -can- count. A stock motor with 155k on the clock, exhaust leaks, a horrible launch and the original injectors -will- run those times... Those times are from my first trip to a track, ever.
Stock numbers are another half second lower, with a better launch I probably could have come -very- close to stock times...

Corrected times are
~17.211 @ 79.01MPH
which is the stock times exactly... and as I said earlier, I have more in my car and launch, so thats not bad at all...
