Powerfc Tune And Boost?

[evil_weevil]

Hi guys,

Getting my car tuned late next week, and so far its just ya 33gtst with "basic mods" using a turbosmart single stage boost controller (flick between standard 7 and its meant to be set to 10psi but spikes 50% of the time!) and Im thinking - should I ditch the turbosmart b/c and go back to the normal solonoid to prevent the thing from spiking and causing issues, or as its being tuned (2-3 day tune) will it be alright?

At the moment the car is running like crap and I just cant wait for the tune to stop all these bugs.

But my main concern is boost. is 7psi stock going to be sufficient? Or should I use the turbosmart b/c and just keep it at the one setting?

Or somehow rob a bank and buy an EBC for minimum 500?

Cheers guys,

Chris

You want EBC-- those profec spec B's are 390 to your door step!! look in trader section!!

Otherwise see what the tuner says!! Buy another cheap bleed value and if there any issues with your turbosmart while tuning, ask your tuner to use the new bleed value and see if that works..

If its still spiking, get a ebc..

But see what your tuner says first..

I got my eboost 1 for $550 brand new. U might be able to get one cheaper second hand or off ebay. Its got 3 boost settings which is perfect since my cars main priority is road use, but the 3 preset settings u can jump between at the press of a button makes its easy if u wanna really give it a boot or take it to the drags. I've got mine set at 8 - 10 and 14 psi. I cant see the point of spending the extra money and getting an eboost 2 with the 8 boost settings unless your cars just for drag racing since its got all that extra jazz in there to take care of that kind of stuff.

profec hey?

I'll look into that !

I'll also keep an eye out for the eboosts.

I'll give the tuner a call tomorrow, tried this arvo but wasnt in.

If you already have the PowerFC, the add-on EBC is under $400 delivered too from nengun

[Birnie]

Profec Spec II - $385 delivered

PowerFC Boost kit - $365 delivered

How good is that !!!

Maybe I'll get one for that price

[evil_weevil]

as in the powerFC boost controller option?

I think that would most likely be the best option for me.

[evil_weevil]

SOLD!

[Birnie]

Yep..Super stealth !

[evil_weevil]

delivery though - that will be my killer - as in car goes in friday week, will it arrive by then?

is it worth the risk?

[_8OO5TED_]

delivery from nengun in a week? Dont like your chances, but you never know!

[evil_weevil]

Matt, thats what Im thinking too man

[justin911]

save $400 and get one of those $22 bleed valves.. alltho i think there like $35 or so these days.. Its like 10 times better than a turbosmart or gfb bleed valve. plus its so cheap you cant go wrong by testing it out

[_8OO5TED_]

it will take a week to confirm a purchase and transfer the money, especially with a weekend in between. you are gonna have to get something local champ. perhaps loan a good working bleed valve from someone until your nengun purchase comes in?!

If you aren't running too much boost, it probably is best just replacing your bleeder.

I'm on 12psi and PowerFC.

It fluctuates but i can't tell from the driver seat.

Here's the curve......

Slide performance can get me the Greddy profec 2 thingy for a great price...3-7 days delivery.

Still think Ive left it too late d'oh!

[Munkyb0y]

why dont you go with the turbotech bleed valve ($22), and set your desired boost using a boost guage. then the tune will be right for your boost setting, and you can use whichever boost controller you want later, just set it at the same boost level.

Dont be rushed into a EBC just because of your tune next week. Get a turbotech for now and worry about your EBC later. EBC's cost quite a bit so you don’t wont to be rushed into a decision solely based on delivery times.

I have a spare turbotech if you wanna borrow it for a month or so as I have recently upgraded to an greddy e-01 so I can pull the chics like Paul Walker. PM me if you wanna borrow it

Hey Chris!

You will not get the benefit of the electronic type!!

Save your money. The $20 one works fine for up to about 12psi or more.

Or even a small orifice piece that you replace your solenoid with will give you steady 10psi (If the right size bypass hole). It's bypasses enough air to maintain 10psi..

Only when you upgrade the turbo consider a more elaborate boost controller.

I already had the Power Fc installed so all that was needed was to get an electronic solenoid hook it up to the standard solenoid plug then attach the signal & actuator hoses.

Then attach a MAP(3bar) sensor to the input on the power fc.

Haltech sell the solenoids for about $120

Then dial in your levels on the hand controller duty cycle & pressure.

& make sure u have the correct cable/loom
