Turbo questions

[nissanzx]

hi i am kinda new here in fullboost and i want some help answering some questions see i always liked how a turbo function but there is something bothering me. see we know small turbos have a lesser lag than a big turbo and a small turbo boost up sooner (on low rpm) and big turbos boost at high rpm now how can a person make a big turbo start boost at low rpm (like 2000 rpms)? is there a way to do so and if there is ,is there more than a wayto do so ?
how can you control the boost of your turbo? is that the function of the ((turbo timer))?
i would be very greatfull to who answers this questions

Well buddy what u need is a boost controler or bleed valve this will help your turbo spool up quicker

[turbo mike]

sorry tommy26 a boost controler or bleed valve will only increase boost levels
it wont make it achive boost earlier.smaller trim comp/wheel,exhaust/wheel
smaller a/r turbine/hsg,or evan a vnt are afew of many ways to achive

A boost controller CAN help the turbo spool a bit better, but thats just fine tuning. It won't make a day and night difference - the mechanical actuation used to control boost is not an exact thing. As you get closer to full boost, it will start leaking exhaust through the wastegate port with a partial opening - slowing the rate the boost climbs.

A boost controller can help things out a bit by potentially tricking the wastegate from opening until it really needs to open -a bit of tweaking is usually needed to get it just right though.

so u dont need to change the turbo, only a boost controller will do the trick.

how biger turbo do you refer to? because puting a boost controler on a 1000hp turbo isn't gunna make it cum in @ 1500rpm say 2 3500/4000rpm. where turbo mike is correct by takin say a .84 rear off and replacein it with a .63 will make a big diff but it wont rev up as hight(makein power) as the .84. and a bleed valve will make it slower but the amount slower wont be noticebul. due to your leekin boost to gain more and it has to compansate for that lil bit.

anti lag setup, or nitrous will spool large turbos, better still, twin charge it
