Kempower-Motorsport and GT3 tuning?

History
The company KEMPOWER motorsport NV has been founded in October 1989
by Ing. JAN KEMPYNCK.
The family Kempynck has been involved in cars since 1918, starting with René KEMPYNCK, Jan's grandfather, who founded his garage in Koksijde Belgium after the world war, working on the very first existing cars, being the only garage in the region at that time. In those years, there were no spare parts and he had to repair all existing parts. He was truly a pioneer in this area.
After the second world war his son, Léon KEMPYNCK, continued the mechanics in this garage. Unfortunately, he died at the age of 36 years after being seriously ill. But even in this short time, he was well known in the country as well as abroad for his excellent service, expertise and fine mechanics. In 1946, he started to mechanically tune engines with great success. He had also the skills of a very good racing driver and was asked by a factory team to drive in Le Mans. At that time, autosport was very dangerous. Therefore, his father René did not allow him to race.
Jan KEMPYNCK was only 2 years old when he lost his father. Due to the fact that he could not learn the job from his father, he was super motivated to learn everything about cars & automotive technology.
Jan first studied mechanics, then electricity and proceeded to the high school, where he graduated as "Industrial engineer in Automatisation", after which he also specialized in autotechnics and finished school at the age of 23.
But earlier on, at the age of 16 in 1971, he already developed a first electronic ignition system and helped several, renowned tuners to tune the first electronic injections. This was unique at that time, the elder tuners doing 100% mechanic tuning. Jan's occupation in both mechanics and electronics still is very uncommon.
He was actually the first chip tuner in the world, starting by modifying the first analogue BOSCH D-jetronic ECU's, followed by the L-jectronics and the digital Motronics.
He worked several years at Bosch, expanding his knowledge on the Bosch management systems. In addition he worked a lot on dyno's to set up the cars, including doing so for a lot of renowned motorsport departments and tuners. In 1989 he decided to start up a new company, under the name KEMPOWER (KEMPYNCK & POWER). Striving for perfection, he invested highly in test facilities. He was very successful in building race engines as well as in performing road tuning. He developed race engines and cars intensively from 1989 until 1997, such being 80% of his job with 94 championship titles in 8 years. This experience led him to do more and more road tuning successfully, which is now 90% of his job.
Tom KEMPYNCK, Jan's son and the 4th generation in Automechanics, wants to continue in the discipline of tuning. He finished school as Bachelor in "Electronics - Industrial Computer Techniques" followed by his Master of Science in "Automotive Product Engineering" and a second Master of Science in "Motorsport Engineering and Management", also at Cranfield University in UK with success. He is now working with Lotus Engineering Ltd in Hethel, UK as calibration engineer in the Powertrain Department.
Tom has also the same superior race driver skills as his grandfather Léon, with more than 80 podia. In 2012 for example, he became 2012 UK vice-champion and 2012 UK rookie of the year in endurance karting.
He will learn the tuning expertise from his father under the motto 'Knowledge is power and a part of KEMPOWER"

We can state that the KEMPYNCK dynasty carries the passion for cars in its heart, while power rushes in its blood.

I've done a quick Google but can't seem to find anyone that's had this done on their GT3. Maybe Mr. Ramsay will have some info on this...

there is alternative solution for 997.1 GT3 owners

out of the bespoke 911uk works departs, we have developed the 911uk GT3 R edition, I can review some details of the power delivery system that we have developed in conjunction with propulsion specialists from the USA, in the picture below



please email me for further details

Am I the only one who saw that and thought that it would be perfect if you were going to something like LeMans or the N24... :?:

(yeah - probably)

I think you might get less stuff thrown at you if it was on the back of an Opel Corsa :floor:

There's no free lunch. What this kit will do is massively reduce the driveability of the car as it will optimise for power & torque much higher up the rev range. This is fine if you understand that it won't like running much below 4K rpm so it will become something you actively avoid driving unless you are on a track.

Eliminating the variocam reduces the flexibility of the engine, there's no getting away from that (that's why Porsche came up with it in the first place).

The power hike will be at the expense of torque & it will probably be quite a peaky power delivery too.

Nick, you will not lose power at the expense of torque. Power is torque x 2Pi x rpm. What is likely to happen, is that you will make a truck load more torque too, but chances are you will shift it higher up the rev range. Whether that is a bad thing or a good thing depends on your gearing. Thus you use a gearbox diagram and a power/torque curve to make up your mind.

Your statement that it may not want to run below 4k rpm is also slightly inaccurate. If the area under the curve is bigger for both power and torque, then regardless of the presence of VARIOCAM, you will have more of both under almost all rpm.

I speak from experience where we managed to get a 5.4ltr engine, which is factory rated at 350bhp/500Nm at 6000/4200rpm to make 500bhp/620Nm at 7000/5100rpm. No loss of driveability, but zero chance to pass emissions at "standard" idle speed of 775rpm. At 1000 it passes, though...

Laslty, nothing really special about the mod - BMW ///M engines use VANOS - and most real race engines would have it deleted too. Have not seen any of the Z4M GT3s cangarooing around the paddock either.
