PH goes drag racing
A Dial-In Day at Santa Pod gives us the chance to learn about the mysterious world of bracket racing
Don't be too hasty, however. The Nissan was victorious at Santa Pod's Dial-In Day, an event that places as much emphasis on timing and consistency as it does on outright speed. It's not simply the fastest car there that wins, it's the car and driver combination that can churn out run after run as close to a chosen time as possible. So if you have an 18-second car but can hit that time after time, you stand more chance of winning than a car that can sporadically run 12s. Make sense?
It's called bracket racing, a creation originally devised to bring people with varying budgets together to race. By introducing a time penalty on the lights in accordance with the performance deficit, the racing should be super close. As long as the drivers can stay consistent...
Before realising any dreams of winning by an inch or a mile though (the irony being that the Panamera Turbo and RS7 we used are probably quicker than *that* RX-7), it was time for the classroom session. And you thought it was just driving 400m in a straight line. That c-word - consistency - essentially runs through every element of the race to an incredible degree. Take the start, for example. Before the regular lights - a sportsman's tree for this day, with longer pauses between the changes - even come on, there's 'pre-stage' and 'stage'; once both cars have triggered the latter beam then the lights will begin their countdown. But there's 20cm between pre stage and stage, meaning you want to trigger the beam with the same point of the wheel each time around. It's that tight, but if it makes a difference of a hundredth of a second...
Then it's simply a case of launching at the same rpm, managing the wheelspin in an identical fashion, changing gear at the same rpm and crossing the line at the same time, every time. That's the key to being a successful bracket racer, and it's far trickier than that sequence suggests.
Point proven by two chumps struggling in a pair of automatic four-wheel drive cars with launch control. There were jumped starts, failed launch control starts and very slow reaction time starts. There was also the slight issue of the cars running comfortably under 12 seconds (in every sense - 11.7 with a heated seat on is most pleasant) when the rules of the day said no car should go faster than 12.0. Whoops.
What should happen is one qualifying guess run where you record a time that should allow you to guess your 'dial-in' - the time you think you can consistently hit. Ours was then set at 12 seconds, but how on earth do you go about taking just three tenths from a quarter mile time? It proves tricky and I'm way off, recording 12.5. Don't forget as well that once the qualifying runs are done and it's into elimination, jumped starts mean you're out and so does a victory that surpasses your dial-in. No sandbagging, basically.
And here's the joy of bracket racing, because you can be paired against just about anything. In my first knockout with the Audi I'm racing an ST185 Celica and must overcome a five-second deficit. As it turns out the win is reasonably comfortable and I stay in with a 12.7, but that doesn't stop the nerves when you see an opponent racing off with what feels like a huge head start.
The next eliminator is even more nerve-wracking; I'm pitched against an original Dodge Charger that has a dial-in of 16.0 (it later transpires the owner is having some issues), but sounds like the end of the world and looks fast enough to outrun that apocalypse too. Oh dear. In my terror I jump the start and so immediately get disqualified, even though the big Audi proves massively quicker than the demonic Dodge.
It's the variety that proves so entertaining about bracket racing; it's not simply cars of equal performance pitched against each other to find the fastest. There's an unpredictability to it I've not seen in drag racing before that makes it great to watch. This doesn't happen too much what with the actual driving and whatnot, but there are Micras racing Supras, Imprezas against Vauxhall Carltons, Mustangs taking on Volvos and much more, pairings you would just never see. And even with a predominantly novice group, there are some fantastically tight finishes. Which is exactly what you come to watch a drag race for, right?
That we turned up in cars wholly unsuited to bracket racing but left still frustrated at our ineptitude shows bracket racing at its addictive best: even in cars that should have made it easy there was more than enough to attempt to perfect. In a manual car with just two driven wheels the effort - and commensurate reward - of consistency must be off the scale. Which is handy, as there's that Mustang on the PH Fleet now. On green I'm going for it, right?

So in a nutshell a pointless waste of time!

...I'm gonna get my arse handed to me mind you....trust me when the field is separated by a tenth or so then it's not as easy as it looks!....amazing the difference air and track temperature/ humidity can make on even a small car like mine
So in a nutshell a pointless waste of time!
Tufty_B's point makes perfect sense, an electric car must be the perfect choice for consistent starts, providing you can keep the battery charged during the day.

Being consistent in bracket racing isn't simply about running the same time over and over. It's more about the car reacting to changing conditions in a predictable way which allows you to change the dial-in to suit. As we run on alcohol we tend to be affected a little bit less by changes in density altitude than those racers on petrol/race gas but a 4degF rise in ambient temperature would cost us about 0.01 on the ET (elapsed time) about as much as a 9% rise in humidity. That same rise in ambient temp though can often be multiplied in terms of track temperature and we have a 0.06 window from good track to awesome track. It is quite possible to have a really great track at quite low temperatures although below 60degF it can become tricky to predict. Although we don't see it very often, the same happens at the other end of the scale when the track is up over 120degF too. Wind is a hugely important factor too and the same tailwind that causes us to pick up a hundredth of ET would cost us three times that as a headwind.
All these increments of time may seem incredibly small in terms of the piece above about the dial-in-day, but in relation to racing in national events where competition is incredibly tight in the three bracket classes these are the sorts of numbers we deal with. Last year our closest race was won by 0.007s (19 inches) @ 173mph and our #1 qualifying shot at the National Finals illustrates just how close it all gets. Scott Hauser was holding top spot at 0.005 over dial-in so we didn't have a whole lot of room to squeak one in, but in the third and final qualifying run we managed to pull off a 0.001 over to give us the #1 which ultimately gave us the best possible chance at the event win.
Of course there's much more to bracket racing than just this stuff and as I eluded to before, tactics are a significant part of the equation too but that post would be never-ending!
OR are the run times applied to each vehicle not towards the upper limit of its performance? Or do they vary for each run? Take the Leaf. Maybe it can do an 18 at best. Is the time going to be 18, or would it be 20. The article doesn't make that clear, hence the confusion among posters?

This isn't a rabid petrol head post just agreeing that there really isn't any skill to mashing the accelerator on a low powered electric car.
....Chris (the mighty)explained above how complicated/ tactical it can be and how close the racing is. While it may not seem difficult you have to be perfect every time to win...if you think it's easy, then why not come to the Pod and try it out for yourself...got to be a National Champion in the making surely!?

Why don't you open your mind and read my post? I have no problem with the skill involved in drag racing which is significant. What I do have a problem with, and as I clearly said, is doing it in a low powered electric car where you just mash your foot to the floor and leave it there, No balancing revs, no changing gear no worry about wheel spin when you hook third at 150 mph. Just seems pointless doing it in a leaf.
Could you enter an electric bicycle. I'd be dead consistent on one of those even multiple pints down.
Bracket racing is a lot of fun, almost as much fun as bracket drinking when it rains!
