Are they actually upto scratch or are some down on what they would or should(as I wouldnt actually know myself lol) likely achieve in reality??

Reason I ask is, I just brought the turbocharged Mini and done every upgrade(which only leaves custom gears and suspension and lsd) I did to the supercharged version I brought ages ago and it's slower despite being turbo and having a tad more performance standard :odd:..

Supercharged = 302hp/6800rpm 39kgfm/4900rpm 1004kg 143mph roughly
Turbocharged = 262hp/6200rpm 32kgfm/5700rpm 1030kg 137mph roughly

Only 2 cars I've compared, but not alot give the option for both forced induction to have a comparison really...

You wont be getting a yes or no answer. It's going to depend on the car, the upgrade, which real life upgrade you compare it to, etc. Basically, "it depends".

Important things first:

AUP
You will not use “textspeak” (“r”, “u”, “plz”, etc.) in your messages. Decent grammar is expected at all times, including proper usage of capital letters.

This is in the site rules you agreed to when you signed up.

Onto the question. In reality, working out how much power a car requires to do a given speed is just a function of its drag (drag coefficient and frontal area) with a tiny bit of weight thrown in. Since drag increases with speed by a square, the power required increases with speed by a cube - 10% (1.1 times) more speed requires 33% (1.33 times) more power.

In your above example, the cars are more or less identical in terms of their shape and weight is an infinitessimal factor, so we can regard them as being roughly the same car for our purposes.

The turbocharged version has 262hp and can go to 137mph. We'll take that as being the aerodynamic limit - as fast as it can go with that amount of power. The supercharged version has 302hp - that's 40hp more and an increase of 15.3% (1.153 times). We would expect it, therefore, to be able to go 4.9% faster (the cube root of 1.153 is 1.049). 4.9% faster than 137mph is 143.6mph.


Close enough, I'd say.
 
lol someone edited my post??

The turbo is slower which is why I question the outputs added to the game..

My typing wasnt bad enough to edit like that lol, far worse typers on here..

But anyways you gave a fair point, just seems strange how the figures turned out given turbo's suppose to be higher...

Lol yes they did. See above. Does it break the rules? Yes. Sort it out - capitals for names, the start of sentences and the personal "I". You agreed to these rules when you signed up.

The turbo is slower when fully modified because it has less power in more-or-less the same car.

The turbo may have more power as standard than the super, but you're modifying them and the super has more power fully modified, it seems. Try them both as standard and you'll see the most powerful car will be the fastest.
 
Your post was edited because you can't seem to find the shift key, or punctuate properly. Sentences end in one period, not two, and they start with a capital letter.

Are you asking why the turbo'd car is slower? Or asking why the turbo provides less power?
 
didn't know top speed was the question.

eta - I'm confused. Are you asking why a car with less HP is slower in this case?
 
I believe he is insinuating that the Turbo should be faster. A product of the fast and furious culture that has no clue about performance mods, just movies for reference. It all depends on the car, and motor. Some motors are better with a supercharger, some with the turbo. Also the cars themselves and their drive train also play a factor. Can the drive train handle a sudden rush of power you can get from a turbo, or will it fair better with a constant more level surge of power throughout the rpm range.

The amount of power your car gains from modifications in GT5 is just like the car sounds......completely made up by a synthesizer. As shown above the computer does calculate the performance increase properly given the correct top speed, but what the computer can't do is understand that irl and other games you can twin turbo a Vette or Viper, even make a muscle car have 1000hp. Accept that whatever PD gives us is what we get and we shouldn't gripe a bit....lol.
