Hello my name is Ruud Visser. I’m from the Netherlands and your team runs this Scania 164L 560 Truck Puller. In short some of the specifications: ECU system: Adaptronic e1280s Engine: DC1601 V8 15,6liter 32Valve Max RPM: 2900 Estimated Hp: 1600 Diesel Injection system: Ported standard BOSCH pump injectors. Turbochargers: 2x HX60 Holset running @ 4bar or 58PSI. Charge air cooling system: Intercoolers placed in water tank. Gearbox: ZF Rear axel: DAF Max weight including drivers: 9500Kg 100 meter pull in about 10 to 14 seconds. Truck pulling must be popular in the Netherlands as we run more than 50 trucks in different classes. For those living close to or in the Netherlands on 3 September we have the biggest truck pull event in Europe in a village called Almkerk. We run the Scania 164L 560 in the Class 1 Super Sport 9,5 ton with is the top level of the competition. The smallest engines in our class are only 13L or 793 cubic inch and the biggest is close to 18L or 1098 cubic inch and they are domination the class for many years. Aldo the large difference in engine displacement is a lot, the performance of the engines is not that far apart due to the fact that some team run on traction and massive torque @ low RPM and others go for speed having a smaller Rpm range. The second difference will be the fuel system and volumetric efficiency of the smaller modern engines. The DC16 Scania engine: Scania still makes the most fuel-efficient engine as far as I know and that shows. The only modifications we made to the 630Hp as standard engine so far where fitting two HX60 turbochargers with a good aftercooler system, some small modifications to the liners and we increased the fuel pressure a bit and fitted an aftermarket ECU. Being a modern diesel engine with electronic fuel injection you can do a lot more than using a conventional fuel pump. On start-up we don’t have to spool-up the turbochargers as we use a combination of post injections and fuelcut to boost up things without overshooting the max RPM. Also when we got the Pulling Sled moving it can happen that the need for engine power drops very fast giving a boost drop as well. Ones the Sled digs into the ground you will need all the power and boost resulting in a RPM drop. The way I programmed the ECU is to reduce torque by retard the injection and if this will overspeed the engine we start cutting fuel on half of the cylinder still maintaining most of the boost pressure this way. Keeping the enginespeed under the max of 2900Rpm is mandatory as 2901Rpm will be disqualification. The framework: A lot of afford is made to the framework of the truck to stiffen things up. We have done this so the truck goes straight over the track and the framework dos not bend under the massive torque lifting both front wheels @ the same time. The advantage is also that the change that the truck starts to jump on the rear wheel is a lot less preventing damage to the drive train. The disadvantage is that we have to mount the engine in the original place and in a Scania that very up front in the framework so the truck is frond heavy. To compensate for this we have the smallest cabin fitted in from a truck with a 6 line engine and rebuild the complete underside to fit the V8 engine. Also the intercoolers are behind the cabin not only bringing more weight to the back but this will also make it easier to service. Setting the truck up for a run: The set-up is a combination of tyre pressure and shifting the weight of 1500Kg from the rear axle to the front of the truck to prevent that we lift the truck to far from the ground and reduce traction as the angle between the sled and the pulling hook giving less downward pressure on the rear axel. As we can only use truck parts we use a ZF 16 speed gearbox and we only use 4 gears in total.

thats awsome to know that there is pulling in more country's than just america. thats some pretty cool stats and programming u have. sucks they limit ya to 2900 rpm though

I think 2900Rpm will do as for all the teams it’s just a hobby. It’s not like you can bay upgraded parts as we have to custom build all the parts for these engines.
Two only teams have support by the manufacturer of the engines.
The second thing is that a lot more needs to be done safety wise if you want to go up in Rpm.
Than we need to fit protective material around the clutch and so on.

Personally I think setting these roles makes a more competitive.
Last year the class 1 truck had a 10,5 Ton weight and many teams where damaging the drive train as the power went up every year so this year we went down to 9,5Ton.
The second thing was that it was very hard for the sled to stop the trucks on some tracks as we run on traction.
This year the speed on the track has going up a lot with makes is more spectacular but the down side is that the front wheels are coming hardly from the ground.

you run innercoolers under water ?

Yep the intercoolers are submerged underwater and the tank is places on the back of the cabin. We go in to the cooler with over 250 degrees centigrade discharge temp and come out with about 30.

The last even in Eerde Holland was very wet so we did a bit of mud resoling trying to throw the dirt over the sled.

The Dyno testing on the Scania 164 did work out having a lot more horsepower than before and we were able to get the fasted speed on the track making the full pull look like a easy job compared to the other trucks.
In the super final we did have bad luck blowing up the injector controller so we came less than 50cm short to become second.

Next event will be Almkerk The biggest European truck-pulling event with 50 trucks competing

man i love seeing the flames from the stacks. good job.

Today we had a demo run in Cromvoirt Holland on sand track.
We have asked the sled operator to start the pull 10 meters before the normal track so we had more space in case we did go to fast on the full pull line to stop it all.

Most demo’s are run with a shorter sling between the truck and the sled and this will give more traction and wheelies.
For me it was the first time that we had to run with a short sling and man the amount of traction this gives and the acceleration you get from the start. We where running one second faster than all the other compeditors runing a 11.3 seconds on a 100 meter pull.

Onboard

Last demo of the year 2010. Yesterday we had an indoor event in Etten Leur.

This time we had a very short indoor track of about 55 meters and we had to be careful not end up in the bar on the end of the track, it also look like they moved the beer to a safe place. LOL

As we run indoor there was a exhaust gas cleaner installed on the sled and the big fan that runs this unit was power by a generator on the back of the sled. Later on when we had to do our demo run the generator powering the filter system broke down so we rook the special stacks off and went for it, Ow man the pure sound of a V8.

I did my part as co pilot on the Scania 164 having a look at the gauges. And the first run went like creasy so fast as the sled was not able to slow us down so Martijn lifted the accelerator a bit to slow it all a bit down and after apply full power to lift the truck a bit more.

Our second run did not go as planed as the electrical hi pressure fuelpump was not working and we did not have full power, dam last place and one more thing to improve on the agenda for 2011.

We are slowly getting out of our winter sleep and last weekend we had our first demo with the Scania 164.
In Holland we have two organizations that run a semi truck pulling championship.
We have the NTTO 8,5 ton class and we run our truck under the VTN 9,5 ton class.
On this demo event we had two semi’s trucks out of the 8.5ton class and 4 semi’s trucks out of the 9.5 ton class.

Scania 164 and the Iveco from Rino Rocket where the only ones the made it to the superfinal.
In the superfinal we had a floating finish so you go as far as you can.
The national champion 8,5 ton NTTO Rino Rocket went just over 104 meter.
Martijn de Bekker with Scania 164 made a perfect run and whet a bit over 105 meter and won this event.

Interview with driver Martijn de Bekker. Sorry all in Dutch but it will give you some idea how we run things over here.

Some you tube movies of the last pulling event in Boekel the Netherlands.

Last Sunday we had the last demo event before we enter the competition events.
We did make some changes to the engine management system that mode the engine a lot stronger.
@ the moment we are at the max of the turbochargers and it’s time we did get billed wheels for the 2x HX60 we are using.
Also we are well on our way with the development of the bigger injectors.
The plunger house is ready and now we are looking into getting bigger nozzle made and tested.
We are using a P type nozzle with a 8 hole symmetric spray pattern and so far we did find nothing that comes close to what we need as most of the big stuff is asymmetrical mainly used on pro stock engines for tractor pulling.

Picture of the Blue Fox sled. To bad he did not have the breaking force to stop us.


The last project I did was on the Cummins QSB engine range so all models 4 and 6 line with a BOSCH or Motortron ECU fitted OEM. In this case we build and ECU system for testing engines but it can be used for truck pulling as well as the ECU system is open base, same as on the Scania 164 that we use for Truck pulling.

The first podium place is a fact after our first event for the points. We manage to get a 3e place on the clay track with loads of traction.



We still working on getting bigger injector made but so far we did find some more HP in the existing set-up.
Last year we were struggling to keep the engine in the upper RPM range and we are still short of low end power compared to the 18 liter German manufactured V10 for Mercedes and MAN but we got the speed and traction to come close in general performance.




We also discovered that the lower gear ratios no longer work as we hoped due to a stronger engine hitting the RPM limiter like silly so there more work to be done there as well.
