The next generation of Intertechno Lambada

The Lambada Pulling Team from Zwolle, in the Netherlands have built their V8 Hemi powered Modified Tractor called ,,Intertechno Lambada´´ newly during the last winter. After 3 years with the same Chassis, they decided in the fall of 2017 to built a new improved Tractor for the 2018 season. But what´s new and improved on the next evolution of the Intertechno Lambada? From the first view around the Mod not very much, but behind the technic of the Tractor there were made a lots of improvements during the last winter. The Dutch Team built the same chassis, but they moved the crossbox a 70mm more to the back. This means the back engines are more to the rear end for a better balance. They also changed all the little brackets in the chassis for a better performance in the driveline. Also after 5 years with the silver / grey paintjob, they decided to go a new way. They switched to a orange / grey look. Orange is the colour from one of their bigger sponsors called ,,Toplenzen´´.
The new Intertechno Lambada received a new homemade Domex wedge frame with a homemade chrome-moly rollcage, a self built steering with components from a small road car, new homemade steel wheelie bars and a Ralph Banter built Rockwell rear axle housing from the USA.
The USA approved rollcage and the completely Rockwell rear axle were took over of the old Intertechno Lambada. The new Domex frame rails and all the engine brackets were laser cut and bent by their sponsor Tosec BV. from Zwolle, in the Netherlands. Tosec BV. also has laser cut the brake discs of the new ride.
The rear axle has a a billet aluminium differential with a Rockwell ring and pinion gear, a billet aluminium center section and leight weight magnesium planetaries carrier housing by Joe Eder (Eder Motorsports) with special made CAT planetaries. The billet center section and the diff were manufactured by Humpco / GMS Hi Performance Machining in Hamilton, Ohio, USA. Bennie Vreeman of Vampire Gears from Neede, in the Netherlands did the special made CAT planetaries for the rear axle.
To keep the Tractor in bounds, the rear axle received a single wheel brake system with Engler Machine & Tool brake calipers, own constructed brake discs and brake pads from the company called ,,Vekoma´´ (also a small sponsor of the Team).
The drivetrain has a Humpco reverser with a special built Vampire Gears driveline between the reverser and the crossbox and a Banter crossbox from the USA. They have two different crossboxes for the Mod. One crossbox ist built for 3 engines and the other one is built for 4 engines. Those two components are the oldest parts on the new machine. The crossboxes were built in the year of 2000 by Ralph and Dave Banter, but received some new bearings during the last winter check.
The rear fenders were made out off carbon fiber by a company in Germany. After 5 years the Team replaced the old fenders by new ones. The new ones also got a completely new design and colour sheme. The new design was made with the help of Kees Vreeman (Vampire Pulling Team) and MW Design from Schijndel in the Netherlands made the paintjob on the new fenders. Ed van der Hoek from the Cloud Nine Pulling Team made the paintjob work on the new Chassis.
For a good traction on the European Pulling tracks they purchased a set of new cut Firestone Puller 2000 HP tyres with polished Northern Sheen aluminium rims by CM Pulling tires in the USA. At the 3rd Euro Cup round in Made, the Netherlands they tested for the first time a set of new Mitas Powerpull tires on the Tractor. Both new set of tires were cut by Hans Heesakers in the Netherlands.  
The new Intertechno Lambada is powered by blown BAE V8 Hemi engines on methanol fuel. The Lambada Team driving with 3 of those BAE Hemis in the 3.5t / 7700lbs. Mod division and with 4 in the 4.2t / 9260lbs. Heavy Mod division. The power plants have a BAE billet aluminium engine block with Darton sleeves, a 4.5´´ Winberg billet steel crankshaft with MGP billet aluminium rods and Diamond billet aluminium pistons, Veney alcohol cylinder heads with Manley valves, Dan Olson Racing exhaust headers, a Com cams billet camshaft from the USA, a billet SSI 14-71 supercharger with a carbon fiber scoop, a Sassy Racing dual fuel system with a Sassy Racing fuel pump, a homemade aluminium sheet metal fuel and oil tank, a RCD oil pump and a Racepak IQ3 data logger.
The two aluminum sheet metal tanks on the front end of the tractor are for the dry sump lubrication of the front engines. With the Racepak IQ3 data logger they can measure the rpms, the intake pressure and the oil pressure of all 4 engines.
Since many years with the same engine combination, they switched over to a different cylinder bore in 2018. The engines have a bigger bore with 4.440´´ inch and they have changed the intake manifolds to get more air into the engines. The Dingerinks also changed the nozzles in the fuel system to get a higher pressure.
After all the technical insight what are the hopes of the Lambada Team after those improvements? 
The Team hopes and they have seen that already this year, that they had a better balance especially in the Unlimited class with those changes. With all the new small plates and brackets, the driveline stays perfect in place and the new Mod can put all the horsepower to the ground.
With the bigger bore in the engines, the crew hopes to have more horsepower than last year.
Things that the team didn´t know, but what they know now are the big engine failures in 2018. The big damages also were sometimes bad luck.
Füchtorf, Germany was the start of the Euro Cup season. They made nice passes in the Mod class, but in end of Heavy Modified class a rod broke in the front right engine. Back in the Lambada workshop, they found out, the problems were the bigger pistons with more compression and the wet sump oil lubrication system wasn´t good enough anymore for the front motors. The Dutch guys worked 3 weeks to rebuilt both front engines on dry sump lubrication system.

At the next event the other front engine blew up, after only 20m. Later they found in the workshop, there was missing a o ring in the suction part in one of the a new oil pumps. This was the result for another broken power plant. After those lubrication problems, the Tractor ran pretty good during the mid of the season. But in the end of the season in Great Ecclestone, England they junked again one of the expensive engines, but this time the crankshaft broke. They found out the crank was more than 100 runs old. Before the EC the spare parts stock was pretty empty in the workshop, their biggest sponsor Bertus Boer (Intertechno) helped them for the EC with engine parts and from Egbert Dros (Simply Irresistible Pulling Team) they got an older BAE spare engine block. With those support Willem Dingerink won on his 72nd birthday the 2018 European Championship title in the 3.5t / 7700lbs Modified division. But a few hours later in the Heavy Modified class, another engine went broke and again a broken crankshaft. After the EC in Alphen, the Netherlands, the Team found the problem why the crankshafts after 100 runs broke. With the new bigger pistons and the higher compression, the crankshafts were claimed much higher than they believed, that´s why the cranks broke so early. Because of those troubles, all 4 BAE Hemis will get a completely new crankshaft for the 2019 season.
The Lambada Pulling Team will compete in the Dutch Grand National Championship (Modifieds and Unlimited division) and in the Euro Cup (Heavy Modified) next year.
