GearCity 1.18 Progress

[Frankschtaldt]

Stuff like revs being less than half realistic numbers and turbos still not behaving realistically.
I will have a bit of time to sink into it in the morning but with the quick fiddle I just had I get the feeling I'm going to have a pretty big list of suggestions.

Which valves are you choosing and which turbos? The valuetrain effects RPMs, so be sure to compare apples and apples. Also turbo now has 4 stages. Stage I is pretty weak. The larger stages give a bigger boost.

Also note, the RPMs are no longer readline, it's Peak Power at RPMs, but that being said, I did match up stats for a few dozen engines between 1920 and now. So if you think it's off, you'll need some hard data to prove me wrong.

I take back part of what I said, RPM's aren't too low. I'm pretty sure I was making a 2L I5 (in 1950) using a T head but I must have been using a 2 stroke or something because it was peaking at about 1500rpm. It's not behaving that way now so I must have done a booboo in my tiredness. I will say though that I think SOHC and DOHC might actually be revving a little too hard.

As for turbos, I'm not talking about the amount of power they give (though I do believe they are still too low, but I haven't seen stage 4 yet so not sure) but how they produce it.
In almost every real life engine that I have seen that has been released to the market in a natmo and turbo version, the turbo gains more torque than power and peak power output arrives at a lower RPM. Your turbo's do exactly the opposite.

Some examples:
natmo then turbo
Ford Barra 4L I6 - 195kW@6000/391Nm@3250 vs 270kW@5250/550@2-4000
38%more power vs 41%more torque

Hyundai 1.6L I4 - 103kW@6300/166Nm@4850 vs 150kW@6000/256Nm@17-4500
46% more power vs 54% more torque

Porshce 3.8L flat 6 - 294kW@7400/440Nm@5600 vs 383kW@6000/660Nm@2-5000
30% more power vs 50% more torque

BMW N52 vs N54 - 190kW@6600/310Nm@2600 vs243kW@5800/450Nm@15-4500
28% more power vs 45% more torque

There are a hand full of exceptions but they've been very carefully engineered to get around the natural behaviour of a turbo which is to lag at idle, push really hard under power at low to mid range and then peter off again at high revs.
