actually i would like a proper rev limiter too, it gives these cars more realistic feeling, i don't even think they sound now that they have a rev limiter at all!
it's like: wrooorrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.
Sounds like that, it's not realistic at all.
it should go like wroooootoootootootoootootototootootootootootootoo.
(funny)
And in racing cars like xrr and so one would have a racing limiter, like real fast misfiring sound, wrototototototototototototototototototo...
