How hard do you drive on a track day? 90%, 100%, 110%?

Have you any idea how hard your car is working too?

How hard do you drive on the road? 60%, 70%?

Track days are incredibly hard on a car. No problem for an Evo but
bear in mind how much you are stressing the car. Everyone
understands that brake pads wear quickly, tyres wear on the edges
faster than normal but what else?

Think of the stresses on wheel bearings, wheel studs, discs,
suspension bushes, oils, steering joints, engine mountings, brake
fluid etc.

If you are serious about track days and do more than two or three a
year then look at the maintenance schedule of your car. You cannot
expect to do this to your car and then poodle off home and go to
work in the morning, checking only the washer fluid level.

You should think about a service and check over after 3 track days
if they are occurring within a 2 month period. If you regularly
visit the track and cannot bring your car to us then please take
some advice from us for free.

The list below is in addition to the usual tyre and brake checks:

* Change the brake fluid twice a year.
* Change oil and filter every 3000 miles.
* Check the air filter every meeting.
* Clean if cleanable every other meeting.
* Change wheel studs and nuts (if applicable) every year without fail.
* Change transmission oils at the end of the year.
* Inspect discs for cracking and overheating after every meeting.
* Get wheel bearings checked at the end of the year.
* Change cam belt every year (depending on road mileage).
* Check suspension alignment twice a year and all bushes (unless an
off meant this was recently done).
* Check all air, water and fuel hoses and clips for stressing and
chaffing every meeting.
* Check engine and transmission mountings at the end of the year.

Regarding actual track day use, try to follow this advice:

* Take a torque wrench to the track day and check wheel torque after
1st session and then at the end of the session before lunchtime. If
one stud only needs tightening at any time then it is stretching.
Replace immediately.

* Do the last lap of each session a lot slower than the others, let the
whole car cool down.

* Do not switch off immediately on returning from the track.

* Do not put the handbrake on immediately on returning from the track.
It can warp the hot rear discs, because of uneven cooling. Try to
keep the car still with the engine running but with no handbrake or
footbrake. When you switch off the engine put it in gear, do not use the
handbrake.

* Check oil and water levels and temperatures (carefully) before each
session.

Very helpful points! Sayang tapos na yung trackday haha. :D

I always do a cool down lap prior to coming into the pits instead of storming in after a hot lap..it gets everything back to normal operating temps for the car and driver.

I guess if you really are serious about track-driving in general, then better modify your car to help make it last the distance.

Some things to look into would be the hoses. If you can switch to silicon hoses, that would be good, along with your fluids (engine and gear oil, brake fluid, coolant etc.), use the best suited for your car that you can afford.

And an oil cooler too. :)

where do u install the oil cooler? is it for the power steering? or for the gear oil?

RS_Sprint

For the engine oil. :) Although you can put one for both the power steering and the gear oil too.

Cha,

overcooling perhaps ::)

bka mas matagal umabot sa normal operating temp ang engine during morning startups.

so mas matagal kang nka taas ang rpm during idle

Cha,

overcooling perhaps ::)

lubricating oils have an optimum temp of 250-275*F. yes there is a thing as overcooling but less of a problem compared to the other end of the spectrum.

after the cooldown lap, break out the pyrometer and see how your tires are doing and adjust tire pressures as needed.
power steering fluid temp is often neglected and ive seen its effects. ive seen a guy roast his rack after 1 intense day at the track. no pun intended on the "roast" and the "rack"....lol
stay hydrated at all times....cant overemphasize having enough fluids in your system...drivers i mean.

ganon?

kailangan din ba ng oilcooler para sa n/a cars?

where to buy?

What does silicon hoses do that normal hoses cannot do?
