Quote from Eclipsed :Of course it's slower that XRT - the 300kg weight difference influences performance more than 30HP engine max power difference. Cannot comment on power curve though.

Yes and no

Yes, because short distance sprints and cornering the XRT has a natural advantage

No, because the XRT shouldn't be gapping a GT-R after 160km/h.

and also no, because its not a 30hp difference, more like 50. R33s were consistently dyno'ing over 300whp stock during the BEST MOTORing years.

The actual power curve is pretty accurate IMO, the HP and TQ figures from Nissan come in at those exact RPM's. The RB26 is a short stroke, big bore engine so it has the tendency to rev higher and having less TQ compared to other turbocharged inline 6 engines like the 1JZ/2JZ or N54/N55

Please update engine power, it's slower than XRT....

I understand you used the factory rated power, but Nissan under rated the actual number because of Japanese law at the time.

Here is a better explanation

My company won't let us bobtail unless we get clearance from regional manager. They would rather makes us haul an empty trailer instead because it "looks like we're doing bad"

why does engine have 0.1 bar of boost? redline should be higher to compliment that power curve

Quote from UnknownMaster21 :AI Cannot drive this car properly. can't change gears regardless of any setup ( unless it is short, but then they lack speed anyway for different reason )

thats because the engine makes power past the peak HP point and redline, so AI still thinks there is room to go. Ran into same issue years back when i tweaked FZ5. LFS AI won't shift until 500rpm after max HP rpm. Example, if car makes max HP @ 7000rpm, then redline should be at least 7500rpm for AI to shift, for a good reason since the power curve still holds some of that hp

Quote from Jake_Blasted :Thanks man, I made some tweaks and changes to the engine. Let me know how it feels now!

freaking great! good job

Awesome mod, i was waiting for something similar to what i deal with at work.

Engine power and torque numbers look good, but they are way too high in the RPM scale. these engines usually redline at 2000-2500 with full torque at around 800rpm.

Bring engine idle down to 500 rpm. the torque doesn't come in until 1500 rpm which is very high for 12 litre engine.

Best way to do this is to bring the cam timing down.

Quote from Flame CZE :

I don't know what the real turbo pressure should be but surely more than that Big grin

turbo diesel engines usually run crazy high pressure, 2-3 bar on big rigs easily, however diesel engines and their operational characteristics are extremely different from gasoline engines and so far, our editor is too simple for these differences.

For example, a factory 2022 Ford F350 6.7 Turbo diesel here in the US runs roughly 40 psi of boost which is almost 3 bars. Horsepower is 450, torque is 1280 nm... something you can't do in the editor unless you set the pressure at 0.3 bar lol.

The good part about having to run super low boost when recreating a diesel engine in the editor is that the turbo will spool super-fast which is another characteristic of a diesel engine. Those fords will build 3 bar of boost in a blink of an eye. Turbo lag is nonexistent in large diesel engines, it's too small to be noticed.

Quote from Flame CZE :You're right about the max RPM. The real bus has max RPM at 2300 RPM.

I couldn't get the power & torque just right, that's true, but this is the closest we could get Big grin If someone could help me out with getting the curves right, feel free to contact me Smile

Realistic target values:

Power: 148 kW @ 2100 RPM
Torque: 742 Nm @ 1300-1400 RPM
Redline: 2300 RPM

https://barringtondieselclub.co.za/scania/scania-ds11.html

I based this loosely off this 11 liter engine, with less power for this application since the one here is more recent (90's) If the specs you provided are realistic, that means this engine was originally naturally aspirated because the max torque @ rpm is way too high for a turbo 11.9 liter engine. I made one based on the specs you provided as well. Try them, tweak them to your liking.


EDIT:

http://www.kamim.sk/doprava/technika/karosa/700.php

Based on what i've read, the original 1982 bus used a N/A LIAZ ML 635 engine (which explains why i couldn't get the power figures close with turbo) and that a turbocharged variant didn't come out until 1987.

Torque should be coming in a bit lower in a 11.9L engine, and shouldn't rev more than 2500 rpms, i don't know the exact specs of this specific bus and the engine it's using, but i drive trucks IRL and that's usually the characteristics of engines this size.


I love the mod, and you did a great job!

I tried looking everywhere with no avail, but how are you guys accessing the "rotate" buttons under this menu. I have damn near ripped every gray hair off my head by now trying to figure this out lol.

There is no "Upper Control Arm" in the back of the P3 Volvo cars like this one. you have a rear subframe with 1 lower control arm. here is the suspension diagram from V O L V O

Edit: My terminology is also incorrect, the LCA is referred to as a "Trailing arm" (10 in diagram) while the arm that swings up and down with the hub attachment is the actual control arm (8)

Quote from tommer :I have updated my mod with your engine. I gave it a brief try and it felt nice.

Glad you liked it, I had several opportunities to drive 335s in the past 6-8 years and it's a thrilling experience.

^yeah it should be a 3.0 I6 turbo.

Should be something like this, based on the M340i which is close to FZ5 in performance.

Quote from gebinto :Add more power!

Horsepower is OK, the torque just needs to come in 2000 rpm sooner lol

Scawen, is it possible to make ballast weights for "truck" vehicles exceed 200kgs? something along the lines of 5,000kg? or maybe make the ballast a % of total vehicle weight like gross/net?

Just trying to haul actual loads on [TC] lol
