track times

[DURASPANK]

If car was running 2.52 on a 35' best track. What would it be on a 42'.

This question gets asked once every couple of weeks and it is impossible to give a definitive answer. There are to many variables.

 

[DURASPANK]

I was just lookin fer a general idea. I understand the variables from my drag racing days. I couldn't judge 1/4 times from my 1/8 because I had way to much gear to run 1/4.

Here is another form of explanation to your question. My Current SS car Napalm runs 2.977 on my track, 2.941 on the npwdrl track and 2.886 on our scout track, 2.923 on the APR track and 2.917 on the PDDR track. All tracks are 42' tracks. The car is consistent. It's the variations in track gates, timers, inclines, software and a host of other factors that give the wide range in reported times.

So, Kinser is right when he says there are too many variables to provide an accurate estimation of what your car will do on a different track.

I thought I remembered reading where someone here...maybe Opa had a rough conversion that he had figured out?

Duraspank: To answer your question, "somewhere around 3 seconds. It could be 2.9. It could be 3.1."

Maybe you can get Hurricrane to run one of his cars on your track... /images/boards/smilies/biggrin.gif

That's close enough for me.

From OPA: Kinser is right, too many variables. However, I have a test track at home that is aluminum, but 40 ft. Before each race, I take a 4 runs average. Then I do the same when the cars are returned. The majority of the time, these 2 measurements are extremely
close to equal. On an excel sheet, I create a ratio between home and the league tracks. This ratio changes slightly for different classes. Invariably, by using this ratio on my home track, the predictions for the next race are extremely close. IMHO, I believe this method even accounts for the fact that my track is 1 lane, i.e. no turbulence, and the race track times with 4 car turbulence.

How about a twist on this, since OP has his answer:

Our new Pack track this year was a Freedom aluminum, I assume. The hill had to be "formed" from a flat section, it wasn't pre-bent. So not a Best track, from what I've read here.

The curve appears more "gentle" to me. Not as sharp. So I assume that would mean this type of track should be a bit slower than a Best, if everything else was equal?

Son's car ran 3.12. Think we'd be anywhere close to 3 flat? (Yeah, I know...lots of variables)

If it was a Freedom track it might have been only 40 ft so it would be a little shorter than the league track. Or it might have been a 48 ft track. Sooooooo maybe, maybe not?
The only way to know is to send one in and compare your speed on a common track.

Box Stock is a great start to gauge a track of pro standards!

Exactly! Inexpensive to build and you'll get to see how you compare with everyone else on the live feed!

I have a freedom track and the times read are generally slower than the times on a best track.
2.980 on my freedom will be a 2.945 on the NPWDRL track.

 

[W8NONU]

Which set of holes does the NPWDRL track use for their timer? Depending on the holes, I estimate the times could differ by .02-.04 on a comparable 42' Best Track.

I didn't see this response last month.

So you have a Freedom....it's a 40', then? Because I believe their sections are 8', right? So you can't have a 42' Freedom, I guess.

That was what I was trying to figure out. If the steeper hill on the 42' Best made up for the 2' shorter but lesser hill on the 40' Freedom.

Sounds like it more than makes up for it, at least for you. To the tune of about .035 faster on the Best, according to your times there.

We have definitely left some time on the table. Our car was one I drilled. (canted, using a Pro Body tool and a drill bit to tilt the body in it..not precise at all) Cheetah wheels. Dynasty non-grooved axles polished by my son. 4 wheels, one barely touching. DD4H graphite, Pledge on the axles.
Ran 3.12 on the Freedom. My guess is that it should pick up a bit with Nitro wheels, oil, the new TX axles and a better drill job. We will see.
