New engine build Scania DC1601 for our semi truckpuller.

@ Leiffi I don’t know where you want to go with this but making more than 1000 wheel Hp on a rolling road I find a it a mad job knowing on some projects you got more than 600Hp left and over 800Rpm more before the speed governor kicks is and what is the dyno break can not hold? Last time in Greece with the D12A Volvo engine we had our hands full getting to grips controlling the power and wheel speed and this dyno had two breaks in it fully loading one break attempting to hold speed with the second break and cross your fingers when the pedal goes to the floor.
Rolling road great for making numbers but not so great for getting data and making changes that work well on the track. I can do an engine set-up a lot faster if I have 2Km of straight road so I can make the same runs time after time. For most project we only use a rolling road to set begin of injection @ part load even as most rolling road can not handle the power or are not willing having a risk of damage to there rolling road. Just a bit of reality. bif

I was just asking if you have seen same kind of dip in graph when maxing out this type of dyno ? There are 2 other similar dynos here but I haven't heard they have this kind of problem, maybe they just have not dynoed any high hp engines, I don't know. MAHA says max tractive force is 25kN, I don't think we had that much at those speeds.

No did not see this before but seen some other funny stuff on dyno system like freezing screens and break load jumping al over the place and yes 25Kn and any thing over on a MAHA and its game over with the load reading.
 
Power weekend made where we had two pulling events.

Friday evening 9.5Ton VTN semi truck pulling where we end up in first place along with 2 other super final candidates. Problem was lack of time so we where unable to run a pull off.
The pulling sled under estimated the track conditions so we had no problem getting a full pull.
Currently we are back in second position in the championship but number one is still 10 point upfront so we got some work to do.

Small comment on the two videos. The two pulls looks to easy and we did not even use full engine power even in the super final but a lot of team where struggling to get it even moving it up to full speed as they where plowing the track over 4”deep throwing clay all over the track.

Herlev from Finland with the Volvo Titan. Second run he had bad luck as the plug for the ESD came out of its socket closing the air intake shutter under full power resulting in a game over for the turbocharger.

Saturday NTTO event was the first time we run the semi in 8.5Ton configuration with the hook 9 Cm further from the ground.
Big question was can we maintain traction with 1000Kg less weight on the rear axle. Seems we got the traction part working but ended up next to the track and I think one of the knives from the sled not working very well and did all this. OK next time we hope better luck, bit of trail and error help to understand future problems a lot better when we want to run the 8.5Ton NTTO championship next year as well.

takes about 5 minutes to change from 9.5 to 8.5Ton in weight.

Have bees some time that I posted something. Flat out on work.

Still holding second place in the 9,5Ton supersport VTN championship but we are working hard to get a better balance if we want to run 8,5Ton NTTO as the truck is to heavy on the back lifting the truck way to far of the track.

Over the last weeks I was working on a standalone ECU system for the DELPHI F2P injection system to run a test engine.

The specifications are impressive with almost 2900Bar or 42060 PSI injection pressure.
Looks like soon we are going to do a DAF/Paccar MX13 race engine with this system. Holset VGT turbo that is original on this engine will be replaced with a BorgWarner turbo and external wastegate.

Pulloff from last weekend still going strong holding second place in the championship.
Always something new in semi truck pulling land. This time a very hard clay track and a pulling sled that was not able to put his knives into the track so only way to stop things is to apply a lot of weight on the front of the sled and the truck that can make some steed and correct tyres will win the pulloff. Well we got the speed and power to launch hard from the start line but not the traction so we did get second place but gain a lot of point as number 1 and 3 in the championship did not get the balance needed to stay on the track.

How to lose weight in 30 seconds. 9,5Ton to 8,5Ton conversion. Team has been working hard to transfer more weight to the front if we run a 8,5Ton configuration with the hook further from the fround so the sled pull the semi read harder down making the truck wheelie way to easy.

Finally yesterday fist place first time this year and now only 8 point behind the number one in the championship so with only one championship event coming up it will be a all or noting and a bit of luck to gain the points needed and become champion but for this we need a first place and the current number one team need to end up on number 4 position.
Our second place in the championship is very secure. All we need to do is hoop up drive some meter and gain 25 points and that will do as we got a lead of 38 points on the number 3 position.

Finally running great after changing the weight balance for the 8,5Ton NTTO pulling events.
The semi is now going straight on the track and we got the balance we want resulting in a 3 place in Meerkerk and 2 place in Alphen.

Tomorrow is the last VTN semi truck pulling championship event in Almkerk. This is the bigger event in Europe with only semi trucks in 3 categories. Standard semi trucks. Hobby sport and super sport trucks pulling on two tracks.

We current hold second place in the championship with only 8 points behind so we still have a change to win the championship and we will try something radical this year.

Last NTTO truck pulling event. 3 place still need to get some more experience on balance running the semi in a 8.5Ton configuration.

3 Points short to become champion but we did get first place in Almerk and get a lot of very happy fans.

Running NTTO 8.5Ton configuration helped us to get better understanding how we can handle traction and we did apply the same settings on the 9.5Ton configuration giving the perfect balance just getting the front wheel off the ground.

Now it’s time to do our homework and start calculation loads of data and come up with a stronger engine for next year and in the same time start building the new semi puller named the Manne van Janne 3.

Sometimes you have to make a sidestep so we went quick and dirty with the diesel injection on this 3,4Ton SuperSport tracktor. Old school injection pump and we even did some data logging on how the combustion takes place slamming in a load of diesel. Very interesting and some things can be used on hi pressure diesel injection as well.

New diesel project in progress where we going to install a AIM G-Dash for warning indication and 8 menus of sensor and ECU data can be selected.

AIM G-Dash will be part of a Euro 6 DAF/Paccar off road race truck with a MX13 engine.

30.000 views. Thanks for visiting my topic.:thankyou2:

Last pull of the year and great clay track for testing. Traditionally we start making changes on the engine after the championship events.

We made some changes on the camshafts and set the balance of the semi truck in a way that we get maximum traction so the engine will go low in RPM after the start and on the end of the track.
And easy way of finding out if you taking in more air is to look for the point the turbochargers will go into surge as the compressor will no longer be able to pump a low volume of air.
The turbo RPM will jump up a bit and the boost pressure will drop rapidly.
We gained about 50RPM so with this number we calculate the extra air mass that the engine will swallow.
