Time trial racing has by no means been extra common or accessible. What was as soon as seen as a steppingstone to wheel-to-wheel racing has matured into its personal scene, its personal venue and its personal tradition.
It’s a spot for large wings, large imaginations and, as of late, large occasions. And people occasions have taken on a novel vibe. As an alternative of each driver for themselves, there’s a group spirit of “Let’s all go quick.”
Time trial racing appears easy: Quickest automotive towards the clock wins. Scratch beneath the floor, although, and complexities emerge. When executed at a excessive stage, time trial is a particular self-discipline requiring a particular method to constantly succeed.
New to the game? Seeking to shave a couple of tenths in a quest for a private file? Some finest practices may help you obtain these objectives.
Examine Your Head
Whenever you begin approaching time trial as its personal specialised venue, it turns into clear that success all begins with the right psychological method. Motorsports is a head recreation as a lot as some other sport.
You might assume the right headspace entails a complete give attention to apexes and exits, however while you begin breaking down the precise self-discipline of time trial, you possibly can spot among the peculiarities of the game.

So sure, you completely have to be dialed in to pushing the automotive to 100% always, however you additionally must be dialed in as to whether or not what seems like 100% within the second is definitely 100%. This implies realizing your automotive’s ultimate situations in addition to realizing when to push, when to again off and when to surrender.
Underneath the Hood
Going quick is normally about making essentially the most horsepower attainable, however time trial racing provides a novel twist: making that max energy when the clock is operating.
Any engine goes to have a candy spot the place it produces its ultimate energy, and we’re speaking about elements that may principally be monitored by way of temperatures. The three most impactful measurements–and likewise typically the best to observe–are consumption air temp, coolant temp and oil temp.
Normally, for peak efficiency, you need low consumption air temperature, average however not too excessive coolant temperature, and oil that’s heat sufficient to guard the engine.

If a few of these elements appear at odds, effectively, it’s as a result of they’re. And if a few of them appear considerably out of your management, effectively, that’s additionally partially true, however realizing how they have an effect on efficiency is a massively useful knowledge level.
The best approach to do that is on the dyno. Many dyno operators present their customer support by making an attempt to provide the very best numbers attainable throughout a session, in order that they’re typically obsessive about permitting automobiles to chill as a lot as attainable between runs to decrease these consumption air temperatures.
However one thing so simple as operating and logging a couple of scorching dyno pulls can present some essential knowledge factors. Possibly your energy doesn’t fall off a lot, or in any respect, with elevated consumption temps. If that’s the case, good for you. That’s one much less factor to fret about. Or perhaps output falls precipitously as soon as at a sure temperature, that means any laps run previous that time are only a waste of time.
Your guidelines would possibly forestall you from making modifications to the automotive to counteract any rising consumption temps, however merely having this data obtainable in actual time–by way of manufacturing unit gauges, a standalone ECU and even an OBD interface–may help you kind a extra strategic plan of assault. Bear in mind, we’re after that one, winner-takes-all quick lap.
On the Floor
Your tires even have a candy spot they prefer to function in. When you’re maintaining a tally of engine temps, you even have tires to fret about.
For many trendy, track-focused rubber–assume right this moment’s 200tw tires–that candy spot is barely above ambient temperature. This implies you’re prone to run one or two–perhaps three–scorching laps earlier than it’s essential do one thing to handle tire temps.
If in case you have R-compound rubber, sometimes they should construct at the very least a bit of warmth earlier than they begin producing max grip, however even that varies. A tire just like the autocross-focused Hoosier A7 is available in far more rapidly–extra like a 200tw tire–whereas one thing aimed on the highway race market wants further warming earlier than delivering max efficiency.
[How to make tires last longer? Heat cycling]
How about including extra problems to the combination? For example, the variety of warmth cycles on a tire can have an effect on its warmup curve. And don’t neglect about ambient and monitor floor temperature, humidity, and even the warmth retained by the tires between periods. Oh, and if you must drive by way of moist grass to get again to your paddock spot, how does that have an effect on issues?

You see the place we’re going with this. As with engine efficiency, there’s typically treasured little you are able to do about these elements, however realizing how they have an effect on your total grip is a big a part of the battle.
That is the place notes and knowledge are available in. Tires at their max grip stage make themselves obvious on a knowledge hint not solely with excessive lateral numbers however with increased speeds within the remaining phases of cornering and fewer falloff at turn-in. If you happen to’re seeing velocity traces that dip below the imply at turn-in, it might be a driver confidence factor, but it surely may be tires beginning to fall off a bit.
So how do you handle tires to your benefit as soon as you already know the place their candy spot is? Effectively, realizing how rapidly your tires cool is a crucial knowledge level. The straightforward solution to decide that is to take tire temperatures after a scorching pit entry; then take them once more after a cooldown lap.
In some circumstances–say, August at Sebring–you could discover it troublesome to chill some overheated 200tw tires with out merely parking the automotive for some time. So until you’re solely making an attempt to get extra seat time, ending a session after a assured flyer stands out as the most strategic method.
It’s About Time
Bear in mind, time trial competitors is all about setting a single quick lap, so having real-time suggestions is a beneficial instrument. That’s why we’re large followers of knowledge methods that function predictive timing shows. Preserving half an eyeball on a predictive timer throughout a scorching lap is as essential as preserving that different half eyeball in your mission-critical gauges.
We like predictive timers that function massive, coloured digits so we are able to primarily give attention to the highway. If our peripheral imaginative and prescient is choosing up inexperienced digits from the predictive show–that means we’re outpacing our reference lap–then we all know to maintain our proper foot planted.
If these predictive digits flip purple, nevertheless, it’s time to start out devoting a small quantity of mind capability to choices about the remainder of that lap. Once more, familiarity and consistency are your allies right here.

For instance, if you happen to’re down a tenth of a second after the second flip of a protracted, 17-turn monitor, there are nonetheless loads of alternatives to dig your self out of that gap. However down half a second three turns from the end line? Possibly again it off and funky your tires and engine so you possibly can assault the following lap.
Or you possibly can sacrifice that lap a bit to leverage the following one. For instance, you possibly can take an extra-wide entry adopted by a late apex on that remaining nook to construct some additional velocity on the following lap.
An alternative choice: Throw away that lap and use the monitor time to higher reposition your self for the following one. Irrespective of the reply, that constant, real-time knowledge provides you intel that may aid you fine-tune your method for that excellent lap.
Placing It All Collectively
your automotive and your self. What’s subsequent for nailing that all-important lap? Communication.
Earlier than you head out, chat with the others in your session concerning methods and approaches. Is the lead driver going to take an aggressive out lap, or will they loaf it and get on the fuel on the remaining nook? Are you gridded with extra highly effective automobiles that deal with poorly or great-handling automobiles that may’t get out of their very own approach?

How will you all let one another know that you simply’re on that excellent lap? A flash of the headlights? Or will everybody have to look at their mirrors and simply understand after they’re being outpaced?
And that raises one other level: On-track courtesy is essential to success. Preserving an eye fixed in your mirror for sooner visitors and adjusting your tempo to permit these automobiles to move at least impactful second is a talent you wish to grasp, as a result of these are favors you’ll need returned when the time comes.
Get on Observe
If this all feels like we’re overcomplicating what ought to be a easy competitors, effectively, that’s simply the recognition of time trial pushing the competitors to the next and better stage.

The essential factor to recollect is that you simply don’t must attempt to interact each single one in every of these methods at your subsequent occasion. Nobody needs to be caught behind somebody doing math on their fingers whereas they produce a four-axis grid of their thoughts cross-referencing their consumption air temps, coolant temp, relative humidity and solar angle.
Nonetheless, these finest practices level out that this self-discipline is extra advanced than you will have given it credit score for, and that’s what makes it enjoyable.
