Do they really test?

DR’s extremely modern test room with state-of-the-art dynamometer brake. The room, air-conditioned and equipped with all the devices to ensure a perfect constancy of testing, is the best any tuner could wish for.

I started attending kart tracks when I was still in baby shorts (what they were called in my time, the same shorts with tribal tattooing so fashionable today…). It’s all changed a bit: karts, tires, engines, drivers … but one thing has remained constant over time: boasting about non-existent horsepower. You declare 40? Okay, so I’ve got 41, because I beat you by 4/10ths per lap. Or: before tuning, your engine was awful, had 38 Hp and now it has 45. Yes, maybe I go around 3 tenths slower, but it matters little: I gained 7 HPs. As a journalist I was away from the world of karting for about 7 years. From gains declared then to today, about 1 HP a year, a KZ should have reached 54 CV. But at Sarno, on the occasion of the last European Championship for the gearbox category, the maximum speeds have remained the same as those of 7 years ago. Which suggests that there hasn’t been all this power gain. So, to understand how a test bench functions, how a test should be performed and how to understand when they’re kidding us or when they’re telling us the truth, we need to keep in mind a few essential factors.

After two months the engines finally came back to roar in the Akoc with the second race held in Macau. The event was attended not only by local drivers but also from Japan, the Philippines, Hong Kong, Malaysia, China and Singapore. On this occasion a female driver returns to the top, after too long a wait: Bianca Bustamante excels in Macau. She dominates in Junior, but loses out in the final by a whisker after a long duel with Xie Wing Lam Gerrard. And the Senior final was also a thriller.
We interviewed Bianca Bustamante, the girl who distinguished herself in the Asian Karting Open Championship and, above all, in the second event in Macau on June 30th. She confided to us how she managed to reach such a high level and run with the boys.
On the weekend of 20-21 July the New York Race Complex located along the Canadian border and the St. Lawrence River in New York State hosted the Gearup F-Series Challenge with Round 3 on Saturday Round 4 on Sunday.

The Circuito Internazionale Napoli will host the Rotax finals in October: let’s take a look at the features of this much appreciated track that in its latest configuration measures 1.547 km.
The data acquisition has allowed us to have some more information on how the kart (and the driver) behave along a lap of the Sarno track. Interesting to note that with the Rotax Max DD2 geared 36/61 (with this engine one replaces the torque of gears of the primary) you get to change approximately 12 times, maintaining the first gear for about 607 meters and the second for about 882 meters.
What does an engine abandoning us show, in telemetry? How can a driver know from the instrument on the steering wheel that something is going wrong? Let’s see what happened in a case of engine seizure.
Although of a shorter duration compared to the past, the summer break is a delicate moment for every driver. Let’s see how to deal with it in the barest minimum terms.
Marco Ambiveri again makes us participants with this compelling and emotional story of his feeling with the 100 engine, exalting it still today as the most engaging engine any kart driver has had the luck to try. An unforgettable sensation.
