max boost

[323_mazdabator]

hey guys i have just done a bpt conversion and am wondering if i get a boost controller what is the max boost i can run on the factory computer? is it worth buying a a boost controller? all help is appreciated

the stock computer should cut fuel at approx 14psi ( or 1bar ). It may vary slightly depending on your intake setup.

Yes it is worth getting an aftermarket boost controller. You will find that even with a small boost increase your car will seem to be much faster because the boost will come on much quicker due to a slight bleed off.

If you do install an aftermarket boost controller for the sake of your engine don't install an overide switch. If you do then label the button SELF DESTRUCT

u speakin from Experience =P lol

or just seen it happen to someone else =P

what is an overide switch? i was thinking of getting a turbo smart dual stage...
has anyone heard of turbo xs brand controllers? if so what are they like?

[Cosmo Dude]

An override switch lets the turbo over boost, it's intended for short bursts of extra power.


Most people I've known to have them tell you it's only for emergencies or extreme cases but end-up using them for green lights.

I think its also known as 'Scramble Mode' on some controllers. It closes up the solenoid, blockiing off the actuator and forcing the wastegate closed

in simple terms, i forces the turbo to boost as much as physically possible

And as a result.


KABOOM !!!

[Dogo]

no its more like

OWCH!!

from when boost cut hits and the car jolts painfully

then why do it?

[Adam]

U mean its a bit like NOS? In the fact that its a s**t load more power over a very small space of time and will do wonders for ripping your engine apart?

Not all the time. On my Apexi AVCR I have a Scramble button. You set the extra duty you want it to be.......So you can set it to jump to 20psi from 17psi for 5 seconds (you can set the time too). Give you an extra boost :) I don't use mine

[Cosmo Dude]

EBCs have a +ve side. They will reach max boost quicker as the wastegate only begins to open close to the boost setting, vacuum only will start opening the wastegate earlier than an EBC.
