Deep Staging

[Theo@BluePower]

Deep staging = effectively "shortening" your 1/4, therefore quicker ET.

Shallow staging = effectively "taking a runup" and starting the timers going with some mph already on board, therefore trap speed increase.

Hope this helps

If one way does a faster MPH from a faster run up, why won't the same way give a quicker ET from the same principle?

[Road Games]

Because the longer you are on the track the more trap speed you generate simple really...

From experience :

Perfect traction = 13.4 @ 102mph
Marginal traction = 14.0 @ 104mph

Both identical stage technique...

[FPV GTHO]

Yes that explains higher MPH. But it doesn't explain the rest.

If you shallow stage, have a longer and thus faster run up to the start line, and thus a higher finishing MPH, it stands to reason that the 402m that you were timed on would be run quicker as well than had you started an inch behind where it starts.

[Road Games]

No it doesn't stand to reason at all...

I've been drag racing for over 20yrs Chris from Bluepower possibly even longer, now i know we all love a healthy debate and to pull all the facts apart in our search to gain further knowledge but...

How about...

Try staging in reverse... by accident ... when the tree comes down you can fly backwards and quickly STOP then punch that puppy through the stratosphere hoping the wheels stay on the ground, for a 13 sumfin at 105mph probably with a 6sec reaction time and a 20m run up ?

Then let us know the results will ya ??

[FPV GTHO]

Why don't we just stick to the facts then and leave the wild theories/conspiracies behind?

If you've got 8 feet to stage in followed by 1320ft timed, what's going to be quicker? 0-1320ft or 8-1328ft?

Wild theories ?

So real world experience doesn't count ??

I thought you would have all the answers already ,after all you seem to be at the track every other week, why not try shallow and then deep staging to keep it real for us

Can you please explain how it shortens the 1/4? Where is the start measured from?

[dieseltrain79]

Doesn't work like that , there is the trigger beam after the 2 stage light beams . Once this is tripped , then the 1/4 mile Et starts .

[dieseltrain79]

Sorry wont let me edit :/

I meant to write , once you leave the 2nd beam that activates the time .

[Giant]

The timer doesn't start until the tire comes out of the starting line beam, So with both forms or staging you still have to break the same starting line beam, so both forms of staging are behind the starting line beam.

Which means both deep and shallow staging runs are timed over the same set distance.

I can see that when you deep stage you start closer to the starting line beam and closer to the finish line beam. But still timed over the exact same distance just with a shorter run up / roll out.

If deep or shallow nets you a better ET I guess thats up to each racers results!

[PepeLePew]

Ok gents, we're still keeping it civil here, lets keep it that way.

[Road Games]

[Giant]

Delete please

[prasac]

it's exactly the same distance no matter if you shallow or deep stage. if you shallow stage, you leave a little sooner to cut a better reaction that's all.

on a clean pass, the best times we have run 60' & 1/4 mile were shallow stage. we are only talking small margins here 1/100th or 2 of a second.

you also need to remember you break traction sometimes going down the track, we have the benefit of data logging with data logging i can track the RPM which tells me if we have seen any tyre spin. it's basically impossible to compare any pass, there is just too many variables.

the way i look at it is like this, you only have so much power that dictates the MPH you run in a 1/4 mile. there is 2 sprinters, both run the same speed of 40km/h, however, one starts 1m back and the one in front leaves just as the other is in line with him. which will get to the line first? they both run at the same speed, yet, one has already started acceleration and has momentum before the other has even left the line.

FPV GTHO, which track gives you 8 feet to stage in? You don't seem to be grabbing the basics here mate. Read Prasac's, dieseltrain's and Giant's posts, they explain it perfectly.

That was a typo, I meant to say 8 inches. My point either way was you were always timed over 1320ft/402m, but you didn't always start at the same point. If you can start the quarter with more speed you're going to finish with more speed. Nobody has disputed that. But a faster average speed over the same distance should also give a faster elapsed time. All other variables being equal of course.

How about you take your own advice record it then upload to YouTube it would get plenty of likes I am sure!

Why ?

I am sure you realise as soon as you back out of the beams the tree resets and a time would not be recorded if you proceeded to continue on...




Just FYI.

[Ibanezteve]

I think prasac's explanation is the best.
All being equal, the car that hits the line with momentum, as opposed to the car that is stationary, will run the quicker time.

Then why did you suggest for FPVGTHO to try it?

[xf1101]

G,day,
shallow stage - quicker et / slower reaction
deep stage - slower et / faster reaction,

No theory just fact, just run with what ever suits
Cheers

[prasac]

the only difference in reaction time when you shallow or deep stage is that you leave earlier for a shallow stage, you can cut a .000 light if you shallow stage or a .000 if you deep stage makes no difference on actual reaction time, only the length in time it takes to break the staging beams.

knowing you shallow staged, you know to leave slightly earlier than you would on a deep stage, it's basic common sense.

[xf1101]

Thats exactly what i said, if you leave at the same point on the tree then the reaction will be different, as well as the et

[Giant]

Only your recorded RT is different due to the shorter roll out, your human reaction and vehicle reaction are still the same.

[xf1101]

No kidding, the only one that matters is the one on the timesheet, doesn't matter how you achieve it,
Cheers

You have 6 inches.Then you red light.

And that 6" allows a 1-2mph headstart.
