Track question

Track lengths are most likely determined by the track builder or club. Another important consideration
is the scale of track you want to represent.

You can find different track lengths used at different tracks at www.hodragraceregistry.com

I plan on making a track and use this formula to calulate track length.
-------------------------------------------------------------------------------------
1 MILE = 5280 FEET

HO 1/4 MILE = ( 1 MILE in FEET) times (desired scale) divided by (4)

HO 1/4 MILE = (5280*scale) / 4
-------------------------------------------------------------------------------------

With this formula I calculated the following track lengths.
(timed length only, does not include start area and shutdown)

( Blue indicates feet and inches. Unless using a gage that shows tenths of inch, you will
need to round up or down to the nearest eight, sixteenth, thirtysecond, etc. . . )

QUARTER MILE

1/64 = 20.625' = 20' - 7 1/2"

1/75 = 17.6' = 17' - 7 2/10"

1/87 = 15.172' = 15' - 2 64/100"


1000 FEET

1/64 = 15.625' = 15' - 7 1/2"

1/75 = 13.3' = 13' - 3 6/10"

1/87 = 11.49' = 11' - 5 88/100"


EIGTH MILE

1/64 = 10.3' = 10' - 3 6/10"

1/75 = 8.8' = 8' - 9 6/10"

1/87 = 7.6' = 7' - 7 2/10"

In my opinion, this is a question that has divided HO drag racers more than it has unified them and therefore I've come to the conclusion you should pick what makes you happy and not pick on anybody with something different.

Since rail height and width, groove depth, surface material/paint, power supply voltage and amperage, number of taps for power, wire diameter and attachment of controllers all add to the differences in tracks, I again believe we should pick what makes us happy and not pick on anybody with something different.

Ninjatek, I have to question your math on one spot. 1/75 scale 1/4 mile is 17'-6" but 1/8 mile would be half that at 8'-9". Course, I would enjoy racing on either one.
