URD S/C 1/4 mile time

[XrunnIT]

I was told that he did some "secret" adjusting to the S/C....

Seems to me that the average is 5-6 and maybe 7-8 w/ teh URD Pulley.

Average yes.

I'm consistently at 6psi, but have dropped down to as low as 4.5 and peaked as high as 7psi.

Jeff here in austin has hit 8psi on stock pulley plenty of times (stock headers). and RedXR in Oregon has also held 8psi plenty of times.

I've run her before and my old truck. I just gotta get the fee for it, but not like you professionals.

IMO...launching hard and spinning the tires is not very benefical.

negative DA

ftw!

Altitude, Barometric Pressure, Relative Humidity, Temperature, all formulated together.

DA in central TX is usually around 1000' (ft above sea level). :top:
