Does it matter? Only reason I see for giving internal engine specs is as a justification for a particular power/torque curve.
If you didn't know the the size and number of cylinders for each car in LFS, would it make a difference as long as the power/torque curve is realistic/reasonable for that particular car?
I wouldnt think so. Compare a VW 1.8 8-valve and a 16-valve. Both are the same bore and stroke. The 16-valve makes more power in stock form, but driving a similar car, take a Scirocco for example, with both engines back to back there is a noticable difference- but like you said it is all about the powerband and the power delivery of each engine. The 8-valve has a very flat, broad torque curve, with a little extra bump right around 5500 rpms. The 16-valve is a gradual increase in power delivery until about 5000 when it starts pulling hard until 7000 rpms. Both engines are easy to model in LFSTweak and feel accurate in the Gti. LFS's engine system is quite accurate in most accounts, if you get the hp and torque in the right rpm range, it should feel pretty darn close to the real engine, nomatter how many valves it has.
It makes a huge difference if you drive the LX6 and tell me it pulls like a 4 pot then you deserve to be shot :chairs:
I hope the devs do take this kind of detail into consideration as a twin cam engine will obviously behave in a very different way to a pushrod engine. I think this so long as the torque curve looks right mentallity and generalness of engines in LFS is concerningly like Racer.
There's an enourmous number of variables involved with a R/L engine I've never known 2 engines (even of the same type) to be alike. There are always little differences.
I've recently been trying to model my new car, a Pug 306 D Turbo. It only revs to about 4800 and peak torque starts at 2400 and stays flat until 4500. it's been quite a challenge to model, since there's no graph available (Somebody need to do something about that)
You can get reasonably close but it would be nice to have a slightly more detailed engine model. It's gonna be tough tho! i'm pretty sure it's gonna be complicated to code, however simple the model.
