The heat's on: precautions and tips to keep in mind when it's blazing hot!
Some Advice

The scorching summer heat is finally upon us, why we thought it would be appropriate to pull a tip sheet from our Vroom archives for enjoying our karts this summer.

The scorching summer heat is finally upon us, why we thought it would be appropriate to pull a tip sheet from our Vroom archives for enjoying our karts this summer.

The start of summer has brought its typically high temperatures, and just as we like to protect ourselves from heat and sunshine by re-hydrating and applying sunscreen, our karts, too, to counter the extreme conditions, need the care and love they deserve. Let's take a look at some variables to keep in mind to ensure our maximum enjoyment and their on-track efficiency.

CARB

As we all know, carburetion is an essential aspect, always subject to atmospheric conditions, and the extreme heat of summer is no exception. The hot air forces us to opt for leaner carburation. We need smaller chiclés, if our carburetor is thin. 

COOL IT!
In summer, needless to say, the cooling system is vital. Besides checking the conditions of the various ties, tubes and belts, check to see there is always water in the radiator! Make sure the radiator is always clean and free of dirt or rubber from the track which, when encrusted on the surface of the radiator, reduces its capacity to stay cool. Although We do try to have a radiator of minimum sized radiator, if necessary, an additional radiator does solve many of cooling-related problems. In any case, with the outdoor temperature at 40 degrees Celsius, or more, one has to accept that keeping an engine at 45 degrees is impossible. 

WATER PUMP
Still related to cooling system, and in the case of an external water pump, an option is to make it run faster via a larger pulley on the shaft. But don't overdo it, because at high speeds one risks suffering from cavitation, especially with simpler and less efficient pumps.

TIRES
With air temperature over 30 degrees, it's practically impossible to keep a tire within its ideal performance temperature. One measure towards minimizing problems is, obviously, to reduce tire pressure to start with since, as we know, the air in the tire expands as it heats up.

And finally, when the work's all done, and you're safely seated on the patio, a cold beer won't hurt your dreaming of the next big race, will it?
