this is a great thread subscribing

Today we did some testing in Loosbroek and yes we made some progress.

Last year we had hi drive pressure running a 1.10A/R turbine housing to get to 4.5bar boost pressure.
We also notice that the balance pipe that link the two exhaust manifold together was getting very hot indicating a lot of exhaust energy is trapped there so last winter we removed the balance pipe and installed 1.25A/R turbine houses and 4,5Bar boost and very easy spool up of the turbochargers. The only thing that’s is still open is the drive pressure as I did not get a good reading from the sensor.

In Holland we run two semi truck pulling championships. Our Scania V8 is a Super Sport truck with no limits on intake restriction and a RPM limit of 2900 and we also have the HobbySport and this is a lot closer to a standard road going semi truck.

The HobbySport are limited to 2700RPM and have an inlet restrictor of 75mm to limit the poweroutput.

This is one of our latest projects where we replaced a Holset HX60 80mm billed and installed a BorgWarner S400SX3 179182 with a 82mm billet compressor wheel and gain 300 RPM more compared to the Holset HX60 before the turbo drops it’s pressure in the low RPM.

We use the T4 to T6 flange adapter on this truck as well and great thing is not only is it easy to install sensor in the flange adapter but it also prevent that the exhaust manifold flange bent open due to hi EGT.

Nederhemert test day. We did get complement from the FPT (Fiat Power Train) R&D engineers as they support the Iveco tuckpulling team running a cursor 13 engine and they visit our country ones a year for fine tuning the Iveco engine.

Isn't there a lot of air restriction where your intake air reduces from 5" down to the air shut off? Kind of defeating the purpose?

Couldn't you find a larger guillotine shut off?

They are limited to 75mm inlet restrictor.

My bad read that quickly.

Carry on...

Bit of Off Road Fun:pop:

Some pictures from last week 2 day off road rally event where the Toyota ended up in 3 place in class. Being a rally driver my self this car drives very well and it dos not feel like a off road rally car as the steering is very direct.

It looks like we underestimated the power of the 3L commonrail diesel engine as it was tuned to hi temperatures specifications reducing the power output to a very save level.
We did not dyno the engine after we replaced the IHI turbo for a Garrett VGT Turbo and went from 2400 RPM max power operating range to 2900RPM hitting max torque @ about 1600RPM now.

This is something I want to share. New truckpulling team Green Bull with a SISU truck and a CAT C18 engine.

Nice! Caterpillar is where it's at. There's definitely some cubic inch and power to be made there!

What kind of cubic inch is the Scania you run? The C18 is 1106 cubes!

Our Scania V8 only has 15.6L or 952.9 cubes but a lot more head flow area compared to a 6 Line engine but yes we have to do a lot more thinking to get the performance level as some bigger engines. LOL.

The smallest engine in our class is only 610 cubic inch but you can say within the competition we have teams that set a goal the beat other teams or get to a position knowing they can not win a championship but this all behaves it self like one big sporty family.

The Volvo 6 line 16L or 976 cubic inch engines seem to get popular this year so competing for top 5 position will more challenging this year.

That's how it is in our class everyone is just there to have a good time. I pull a small cam Cummins, 855 cubic inch. Not much of a power house but it's a good time.

:woohoo:not the best choice for big power. Weak heads, block, head gaskets, liners, crappy injectors. C15 seems to be a little better.

What I've been told from sim pretty reputable people, the 3406E, C15 and C18 use the same block, same head between the C15 and C18. The crankshaft and cylinder liners are the only difference between the 3 motor models.

As far as I know liners pistons connecting rods and crank are different and can be problematic due to the bore stroke ratio so is it a good power house? Time will tell but the good thing is they have loads of options to modify things in the supersport class as long as your not compounding turbochargers and exceed the max engine displacement.

@ Lieffi. How is Herlevi doing as he was not very competitive last time and will he be in Made this year?

I think these guys can help you out... http://www.cyclone-machine.com/products.php

There are a few guys in the Ohio area that pull mechanical Caterpillars that are supposedly motors that came out of a road tractor. That would mean they would have to be a 3406 (B,C,E), C15 or C16. The only way I can see them competing with the 1150 cubic inch KTA and the 998 cubic inch V8 Mack is using C18 guts. There are a few of them that are not only competing with the KTAs and V8 Mack, but are dominating them. I feel the KTAs reign is over!

This truck has a Caterpillar of some variant in it:

Both of the red and yellow Peterbilt's are using Caterpillar motor:
https://www.youtube.com/watch?v=DzkP6Q2_z4M

The red and yellow petes of the walkers are still 893 cubic inches. Some of cyclones engines are using a 5.7" bore but still use either the 6.5" or 6.75" crank shaft.

Walker's are still running 893 cubes, huh? Not that I don't believe you, but they are doing pretty damn well being 250 cubes smaller. I'd be interesting to see what would happen if they ran C18 guts.

Maybe there all running 893 yet?...

Do you know if Cyclone is building on Walkers and Hoffa's truck? How about Giulitto's truck?

Because at that level the displacement doesn't really matter, that's like saying that they shouldn't be winning as much as they are because they are running a single turbo against the multi charger trucks.

Those engines would not be reliable at the rpm they turn if they were using the C18 crank due to the rod to stroke ratio as tall boy mentioned above.
