car is very slow with 100% accurate specs

The real world top speed for the car is ~90 MPH, but I can only get it to 60 in RoR
I made the car 100% accurate, with correct horsepower, torque curves, transmission ratios, and weight
I've also decreased the fusedrag to 0, so that shouldn't be it
Any help is appreciated

probably ror being ror.If I remember right the pajero had option for real life hp in truckfile but that didnt drive good

also the torque curve you have going on is funky its making 0hp at higher rpm

that's intended, i'm trying to simulate an old rpm governor, instead of what I assume to be a basic electric limiter
the max rpm irl is 4500 (at least with the I6, idk about the V8)

maybe try increasing the final drive, or maybe increase/ decrease the ratio on the final gear.

that would honestly be a last resort if other stuff i do doesn't work, just so i can really keep this very accurate
i'll either try to increase wheel friction, decrease engine inertia, or both if i have to

and thats probably what breaks it :/ ror is picky when it comes to that

but the thing is, the car is at max torque when it reaches 60 and can't go higher
i might try removing my custom governor but i don't think it'll work
 
I guess it's not ideal but might be worth sacrificing the realistic values for realistic performance

As for why it's not achievable when it should be, I don't know. I had this problem myself but it was caused by fusedrag.

You can check what the problem is by adjusting values (one at a time)
- your fusedrag is not defined or defined wrong (remove, compare, add, compare)
- you're running out of grip (add friction to wheels)
- you're running out of power (add HP to engine)
- you're running out of gears (add extra final gear or increase RPM limit temporarily)

replace the 1.9 in the fusedrag to 0, that'll help!

I got it to go 80mph by changing 1.9 to 0

So I guess that means that even if you change the fusedrag itself to 0, the width still affects it
I haven't seen a lot of wheelspin, but how fast are you able to go if you increase the friction

1.9 is the width of the car, 0 after the airfoil name is the actual fusedrag

The fusedrag area coefficient is before the airfoil name as per the Truck file format. This gets your vehicle to 83 MPH:

Code: 
fusedrag
49, 56, 0, 0, NACA0009.afl

Setting the width to zero is actually a common trick used to help reach the desired top speed. You'll need to further tune your engine/gearing to achieve a higher top speed.

I thought I understood the docs pretty well, but I guess that's one exception
I'm just confused as to why it said airfoil name twice, both before the coef and after it. But yeah, fixing that gets the car to a good speed.
Now I have to increase wheel friction because as a random steam review for BeamNG put it simply, "The car slides like it's on ice"
