Rev Limiter

[Blair]

may be wrong place to post...

raising the limit to 8K in a V...possible at all??

pointless or not

forged or not??

cheers

on a stock turbo, its pointless. they run out of puff at about 6.

it is however possible, but id recomment getting stiffer valve springs first.

i had my old one at 9k on the dyno, and used to rev it out to 8500 almost every time i drove it.

[Guest Enzo]

he has a tdo4,

i would not recomend it to be honest, im pretty sure the glanza is 7400 or there abouts,

after about 7500 the you start to get 'float' which requres the use of uprated valve springs as rick said,

[Blair]

thanks boys...

uprated valve springs - idea for prices: parts and labour and where would do this??

@Rick what set-up would you have??

@Enzo...whats this float thing?? :S i'm gonna have a look see to find out more on this

cheers

[Guest Enzo]

here is a perfect vid showing valve float.

to sort it uprated valve springs from the likes of cruise is whats needed. check the forsale section they arnt cheap.

Good vid

cheers man

vid shows it spectacularly!!

found some cruise ones @ £215...so you're right, not cheapo

once fitted is it just a case of having it mapped to 8/9K or do I need uprated head gasket etc??

my thanks again for all the info dudes

[Guest Enzo]

it really would not be advised on standard internals on a tdo4 at a bar, rods have bent at 8k

you really need to lighten, balance and forge to do it properly when your talking about boost and high revs.

[Blair]

was thinking of going down that route, but wanted to know the first steps involved.

superb for all the info
