Boost controllers

[croat]

I have a dual stage boost controller (turbo X's) and will be hopefully getting it in the car soon.

What do you people think is better (taking money into account) a dual stage boost controller or Electronic Boost Controller? Cause i am thinking of selling and buying a EBC due to the "spiking" issue... How does this work?

[ed]

my personal preference is EBC as the spiking is not as big/sudden as bleed valves, having said that, there are many people who are happy with a bleed valve.

I prefer my Blitz EBC, holds boost very stable, plus i have 4 settings I can choose from in-cabin.

I was told that when your car nears redline spiking occurs and can make the boost level raise heaps. If this happens can it stuff up your turbo or engine?

yup.. thats the one.

EBC just is more efficient in opening the wastegate at the exact PSI, meaning that its not likely to let the boost creep up too much past the setting you give it. Generally with an EBC you can safetly run more boost and hence more power assuming everything else is working ok.

Thanks heaps... what is the best EBC to get and how much do they various brands cost? Do Apexi make one?

[ed]

yeah apexi AVC-R....rice rice babeeeeee

try and get a dual solanoid unit.

Blitz Spec-R is one that comes to mind...

GReddy Profec A (2nd hand only)

just a few off the top of my head.

Is the apexi one any good? how does it rate to the others? I love the look of them!

aside from the consistency factor, having the in cabin control is the best. you wanna give it a hit all you do is turn a knob and the car is totally different. it rains, you turn it down and avoid your rear end snapping out (to an extent)

Spiking occurs when you change gears.. not towards redline.

eg..

you have set your bleed valve to 10 psi.

you take off in first and red line it.

you shift in to second and slam on the gas. the boost flies up and for a slight moment, it over boosts to about 12psi and then drops back down to 10 and holds it there..

the point when it hits 12psi for a fraction is what you call BOOST SPIKE.

this is due to the way that bleed valves control the wastegate.

Electronic boost controllers provide a more smooth wastegate operation and therefore you don't get SPIKES.

has nothing to do with overboosting at red line....

I don't think there's much wrong with the AVC-R except for price, rice and the fact it only has dual mode operation.

and that it is old technology and has been around since 1998.

I love the apexi's rice gear, it matches with the rest of the blue in the cabin... Can someone post up a pic or link with the Blitz EBC... Are those "in cabin" settings just higher or lower boost settings?

[MrGTST]

I have an Apexi AVC-R and havent had any problems with it.. You effectivly get 3 settings as you get two programmable and of course off... So effectively you can set it up to low, med and high ( that is what mine is set to do )

Very happy with AVC-R... No Regrets...

But at the end of the day its your choice...

arent u also able to set boost to rpm on the avc-r?? i was initally considerin gettin the blitz i-D which is smaller and a lil cheaper but to get the extra functions such as temps a/f power readouts and setting boost to speed (which i dont see the use of) u have to buy the blitz power meter.

[T0nyGTSt]

Scramble mode lets you set boost to rpm/gear.

I thought scramble button lets you overboost by x psi for n amount of time???

the trust E-01 is the new kid on the block and looks to be a very capable unit.
