yes they can.
so we've established that the best way to make a vtr hit 60 in 2nd is to raise the limiter! lol. would that mean ur guna burn ur engine/gearbox etc out even quiker ye
depending on how high your RPM limit is set will determine what needs upgrading.

the engine manufacturers are not stupid. they've put a limit in for a reason which is to prolong the life of the engine. Increasing the limit by even a small amount and allowing the engine to rev to those amounts will wear out it exponentially not linearly.
i.e. the life of the engine is reduced quite dramatically (on a large mileage scale).

the ONLY 2 ways to increase gear speed is to
A)fit a longer gearbox
or
B)raise rev limit

or to narrow it down further, the only way to hit 60 in 2nd on a vtr is to raise the rev limit
lock ban delete.

if so saw one of these on a vid of a supercharged clio v6. they do look shit hot...
also found it cheaper here... :... http://www.potn.co.uk/-_c618_4518_4522_p1615009.htm

so for the sake of showing of to ur mates about how fast u can go in second its not really worth it, it seems andys quikshift kit is best for making ur sprint time quicker

standard position is fine, but the standard cold air feed is restrictive at higher speeds, as is the filter (although filter has more to do with keeping induction noise down). replace both and you're laughing. using the term 'forced air induction kit' is a common mistake, as said the only way to physically force air into the engine is to compress it by super/turbocharging.

blowing up your engine in front of your mates is never cool. then again so is showing off how slow... sorry 'fast' a vtr is.

lol you want a sequential gearbox for 100quid ? no it makes the throw between gears a lot shorter that's all

not really, plenty people have 16v engines with a 7850RPM limit that have done lots of hard miles without any problems, if you do frequent oil changes then it will be ok.

so they leave it ramped up at 7850 for a long duration of time and it hasnt gone boom? i doubt it. It'll wear the engine far quicker fact.
They'll only be up there for a brief amount of time. and then they'll realise there is fock all torque at that region anyway...

As sean sed it just shortens the throw between gears but deffinately worth it imo, if your into 0-60 sprints that is!!

i dont mean sitting on the rev limi.
and with peak power at around 7600rpm on 708 cams thats where the rev limit needs to be, it doesn't get raised for no reason!!

how was it measured mate?
never mind, he's taking nonsense. to hit 82 in 2nd on 15" wheels he'd need an 8500ish rev limit, on 17" wheels he'd need an 8000 limit (assuming power to get there). tuned vts's dont run that high a limit.
