There are only a handful of issues of realism in this game, all of them can easily be fixed. Things like having the ETK i series ABS work the same as the SBR4, or having a DCT car still be able to stall and shut down, however one of the weird things was that no matter how big the turbo psi was, the torque curve would still peak around the mid revs. Now, for some cars and turbos this is ok and realistic, and since i know that each torque curve is manually drawn i wouldn't ask for too complex simulation, but that being said, the point about adding a bigger psi limit and a bigger turbo to a car is that it moves the peak torque backwards into the redline, giving you a much more angled torque curve without having to play with the cam timing (another thing that would move the peak torque into the limit). Since we are on the subject, sometimes turbos just heat up a little bit too quickly. Since there's already oil coolers and improved radiators for engines, why not a way to improve on the cooling for turbos? or be able to add a bigger or smaller radiator?
Older cars will not have as advanced safety features including ABS (yes this is realistic). Also turbo cars usually make their torque in the middle of the rev band in lower psi applications such as the average consumer car, this is because they continue making power after peak torque due to the relationship between torque and rpm equalling HP. Your ideas based around the angled torque curve are due to the turbo not being spooled and unable to produce a useful amount of exhaust pressure to spool the turbo and make boost. The torque curve below is a good example of this, if i sit trying to spool on the brakes, the car will not take off until around 3500-4000 rpm as its unable to produce any boost --- Post updated --- Turbos also have a line in their jbeam which controls the heat it starts overheating, you can easily raise this number, disabling the effect of the turbo overheating. Radiators also have a variable for their size.
I think you misunderstood me. ABS have changed through the time. ETK I series has the basic IRL ABS. The ones that would release the brakes when it detects brake locks and re-engage them. However, as time goes on, more and better ABS have come out allowing for a much more precise control and not always having the brakes lock up before activating. Sometimes i think i am imaginating, but sometimes it feels like if the game uses the same ABS for all cars regardless of age. As for the turbo, that's not what i meant. Open up the torque curve for any car with the stage 3 turbo and play with the wastegate function. You could have the wastegate set to highest and yet the peak torque comes up at the mid range, never at the top, which would be more realistic. The game seems to treat all turbos like if they were low psi.
About the ABS this is probably the case from your perspective but i'm sure if you accurately recorded wheel speeds and brake input they would be much different between the cars. However you cannot tell this when playing because i am fairly sure that you do not have force feedback on your pedals. On the turbos i sort of agree with you now, but not with the statement about the torque, most cars will never make peak torque at high range of the torque curve as they always continue to make power past it. The cars in this game also do not make very much boost or very much power when you start to get into boost above 40-50 psi, the car is basically turbo reliant however, this is why you see small engined drag cars running antilag. Not sure if you will now what i'm on about in this next bit but it should make sense. (cant remember if value is exhaust factor or exhaust power, not important though) In the turbo part of an engine jbeam there is a small table which contains RPM, efficiency and exhaust factor, in this case ignore the efficiency column. Anyway the RPM is self-explanatory but the exhaust factor column defines the multiplier given to the exhaust factor determined above, this determines how much exhaust power is given to the turbo which then determines how quickly the turbo will spool. the problem with this is that when changing the wastegate boost pressure these values do not change which leads to the torque and power staying in the same spot on the torque curve but basically being raised to accommodate the extra boost.
That looks like an easy fix, but i am sure the devs have their reason to leave it like that. Still would want the peak torque to be on the late end tho. Maybe with some cars you would be able to reach higher speeds that way.
Which cars are you referring to? As I said before, the cars in this game do not have boost high enough to be boost reliant to make power. If you really want to make the cars turbo reliant, go into the engine jbeams and simply have the exhaust power value (not the ones in the table). It will basically give the effect of being unable to spool at low revs making the torque basically shift higher in the rev band.
Any car? With high speed to reach you face a dillema. You want to go full throttle and go as close to the redline as possible while also maintaining torque. With some cars that lack torque at the very high end you would be limited on the speed by a few miles. Even tho this doesn't apply to it, the SRB4 for example has terrible high end RPM torque and even if you shorten the gearings you might lose speed (the car doesn't redline at 6th gear) because there is not enough torque to take it to the same top speed as before.
