Sport Auto “Tuner GP 2018”

KOMO-TEC participation “SPORT AUTO HIGH PERFORMANCE DAYS 2018”

Lap Time 1.07.3

After a two-year absence, the Komo-Tec team was back at the Sport Auto Tuner GP this year. Our models Exige EX460 and a 311-475 with sequential gearbox started in the sports car and Funcar class.

The 311 was at the first test on Friday quite strange from driving. The car was quite unbalanced on the rear axle and was prone to sudden oversteer. This does not necessarily help to get confidence in the vehicle, especially in the fast corners.
Here a good analysis was required which we were able to work out with some ideas to improve driving stability due to many years of experience in motorsport. The previously achieved lap times of 1.10min were unacceptable for such a sporty vehicle as the 3-eleven. So we put the car on the chassis dyno and first adjust the input values.
We deliberately arrived with the Lotus default setting, (axle geo and damper setup), however, had to realize that this is not suitable for Hockenheim short connection

Changes in the area of toe in and camber, especially on the rear axle, brought a significant improvement in driving stability, as well as changes to the dampers and Anti roll bar settings, and in the end the car was very homogeneous and clean, as known from a Lotus.
Thus, speeds of up to 192km / H in the “Querspange” were possible (previously 171km / h) which is one of the absolute top values ​​of all cars tested there. All these measures gave us a lap time of 1.07.3, which is respectable, but still falls short of our expectations. The data recording and test drives gave us a few more hints what to optimize on the 311 especially for Hockenheim small course to crack the 1.07 and later also the 1.06 .. we are off and will tackle this goal again

 

So much you can say … at longitudinal dynamics it is not 🙂
straight through the sequential 7-speed transmission built in by us in combination with the power upgrade to approximately 475 hp, this vehicle unlocks its full potential. In the final race on Sunday we were able to record a respectable 3rd place behind the Corvette and the Viper of the team Geiger Cars. Our Exige was without complaint the whole weekend with lap times around 1.09 on the way, since the Exige for GP sticks like SPA and Nürburgring is tuned for this event unfortunately nothing better to achieve, since both cars were moved by only one driver and we our main attention on the 311 wanted to lay this weekend.
We would like to thank our driver Winny Klein for his driving commitment and his strong performance with two cars this weekend and are very happy that the whole event could be finished without damages or failures of our vehicles

 

Be curious about further events, projects and conversions ….

 

See you on Track

Komo-Tec achieves best lap time at the Nürburgring GP circuit

Started on 22.05.2018

At the KT-Track Event at the Nürburgring (15.05) we were able to set a new lap record, with a time of 2.11.69. So far no road registered Lotus has reached this mark.

We see a real chance to undercut this time when we will start with new tires. The used had already completed 3 trackdays.

“Race Fuel” – Myth and Facts

Started on 27.09.2017

Mystic powers are often attributed to the fuel in the current Formula One. Although the regulations stipulate “petrol station gasoline Super Plus”, the permitted additives from the mineral companies are precisely tailored to the engines of their customers and thus have a significant upgrade in the performance of the Formula 1 engines.

The regulations allow only a maximum fuel quantity of 105 kg per race and a maximum flow rate of 100 kg per hour. This considerably limits the use of additives.

However, “free” fuel mixtures with a high proportion of alcohol, such as it is used on “quarter-mile” races or speedway and sand track races, can lead to considerable increases in performance. Ethanol and methanol are added to the gasoline with a proportion of up to 80%. The oxygen atoms bound in the molecules of the two alcohols cannot be released during combustion and thus do not act as a chemical compressor.

In contrast, nitromethane has free oxygen atoms that act as a chemical compressor. Nitromethane is only added in very small quantities (max. 15%), is very expensive, is subject to the laws of explosives liquids and leads to extreme loads on the engine components.

However, the advantages of the alcohols as fuel also have some disadvantages:

Advantages:

+ very high octane-rate (up to ROZ 160), which allows an extremely high compression ratio (up to 17: 1),

+ high evaporation heat (or actually “cold”) leads to a high internal cooling of supercharged engines,

+ Reduction of the thermal load on the motor components.

Disadvantage:

– low calorific value (only about 50% of gasoline) and thus significant additional consumption, which requires considerably larger injectors,

– the optimum mixing ratio drops down to a lambda of approx. 0.5,

– With high proportions alcohol and gasoline tends to “demix”.

SuperPlus: ROZ 103, calorific value 10.200, heat of evaporation approx. 80

Methanol: ROZ 160, calorific value 4.700, heat of evaporation 270

Ethanol: ROZ 150, calorific value 6.400, heat of evaporation 225
