Classic car related question

Royale with Cheese

Ok may sound like a stupid question but I was just curious...

So I was playing test drive unlimited (a computer game I know but stick with me here). In the game you can drive various types of cars past and present. They don't handle realistically but they look identical to their real life counterparts, exterior and interior.

I've never done this in a real car for fear of blowing the engine up but in the game as in any computer game, when you start the race it will put you in neutral on the grid and you can get the revs up as high as you want. The car won't move off until it says go as you're not in gear.

On nearly all cars when you get the revs as high as they can go it will bounce back and forth from 7000 to 8000 or so. In the classic cars, certainly the ones from the 70's and back, when you rev as high as you can it will just get to 8000 and stay there.

Assuming this is true in real life, what's the reason for this?

I'm going to guess that they are simulating a rev limiter. On modern cars the computer will stop the driver from revving the car too high, and will cut back on the revs. I presume that to model the classic cars, which have no limiter, they just let them rev up to the max (but it looks here like they didn't code different max values for the different car).


I think

Cool, I figured it was something to protect the engine that was missing from the older cars.

8000 revs isn't the max on all cars by the way, just the figure I gave. Every car is different and I think apart from handling everything else is realistic enough so the rev count should be.

If the car is with carburators u only need a little thing in ur ignition system

A little thing to do what?
