I found a good cheap boost controller for $22!!!

[Cubes]

Are you sure you didn't install it backwards?

I will be going an EBC once I get a decent turbo on it.

[TokyoTaxi]

It WAS installed correctly :uh-huh:

All I can think is that since I'm running 1.2 bar ( 17.4 psi ) and I've got a HKS GT25/35 is that the boost pressure rises too fast for the spring pressure to hold accurately / smoothly.

I kinda knew it wasn't going to work on my car before I even got it, but since it's already been sold to someone else and I only lost $10 on the deal it was worth a try.

Oh well, EBC 4 me I guess

[Oosh]

Yeah, I'd say in your case a higher spring tension is probably necessary, for those looking at electronic variants make sure you give the Jaycar IEBC a good look in, far cheaper than name-brand stuff and arguably more effect once setup (i'd love to see a comparo though) however you DO have to build it yourself and set it up on a dyno for optimal results.

FAT32,

Be sure to get a decent ebc that monitors boost levels and adjusts duty cycle to suit.

Something like an AVCR or Blitz SBC-iD.

:confused: I was just going to get one of those GReddy Profec B Spec 2 jobbies. No good ?

HI FAT,

Did you have it installed after the solenoid? If this is the case you will get symptons that you describe. It must be installed before the solenoid or bypass the solenoid altogether.

The controller should suit application as high as 25 psi.. If you are running less than this then the controller will handle the pressure with joy.

I think FAT said it was on an HCR32 GTST so he doesn't have a standard solenoid.

Hey Mark,

Essentially, it was connected to the boost pick-up point ( a fitting bleeding boost directly off the pipe leading back into the engine ( after the intercooler )) and the outlet of the bleed valve went directly to the wastegate actuator. I don't have a boost solenoid anywhere in the mix.

Does that make sense ?

[Cubes]

Fat32, if the setup is prone to dropping boost as you are running the turbo at the limit it will be benifitial to run a ebc that monitors the boost and adjusts the solanoid in real time.

Simple ebc's where you dial in a knob or duty cycle percentage don't cut it.

Depends if you really want that extra 15rwkw from pushing the turbo just that little bit more.

If its not the case and they turbo can supply the amount or air required then I would say the bleeder you received was a dodgy item.

[simark87]

HEy Fat,

Cubes has already picked up on it but pm or email me your addy again and Ill send you another barb to try. I have a feeling the one where the ball sits in may be faulty. Sometimes they have a scratch or flaw where the ball seats and it wont seal properly, letting pressure through know matter how much you tighten them. I check them all individually but its possible one may have slipped through. It should not have an issue at all with 17 psi..

If your using external wastegate dont go with the profec b spec 2 as tey such with external gates. Go a hks evc

I have a boost controller which is worth zero dollars.

its called a drill

[jrdsports]

hi guys

I bought one of these and held test's against the main ones on the market.

We used a Dyno for the test, the test car was a 02 wrx.

We sell the PowerUp MBC by the way.

Test Results.

Turbotech, Slight boost Spike mid range of about 1.43psi @ 16psi.

2.12psi drop off at 7600rpm. Quicker spool than standard by 200rpm.

Adjust not very accurate at all, takes a while to set up.

Price Good.

PowerUp MBC

Slight Boost spike mid range of about 0.98psi @ 16psi

1.70psi drop off at 8200rpm. Quicker spool than standard by 700rpm.

Adjustment alot more accurate / Hs Dial.

Price: Afordable

GFB

Slight Boost spike mid range of about 1.22psi @ 16psi

1.95psi drop off at 7900rpm. Quicker spool than standard by 800rpm.

Adjustment alot more accurate.

Price: Afordable

Turbo Xs MBC

Slight Boost spike mid range of about 1psi @ 16psi

2.10psi drop off at 7600rpm. Quicker spool than standard by 500rpm.

Adjustment alot more accurate but need allen key.

Price: Fair

Turbosmart

Slight Boost spike mid range of about 1.30psi @ 16psi

1.85psi drop off at 7900rpm. Quicker spool than standard by 700rpm.

Adjustment alot more accurate and easy.

Price: Higher than the rest.

Basically there all close, but we believe money for value the PowerUp unit has a slight edge. That is why we use and sell them

G'Day Mark,

Thanks for the offer but one of the guys from this forum has grabbed the valve out of my hot little hands and fitted it to his car already so I no longer own it

The thing is, if I screwed the adjuster in ( not all the way of course ), the boost would hold but would not release pressure and she'd over-boost to about 1.5 bar ( 22 psi ). Backing off the adjuster 1/2 a turn at a time made no difference until a point where I'd backed it off another half turn and it then only made 0.5 bar ( 7.5 psi ). I pulled the valve off, chacked the ball and the seat, checked the fittings for obstructions and all was fine. I reinstalled the valve and tried it again with almost the same results. :confused:

I removed it alltogether and re-installed the bleedvalve that was fitted before and it all behaved per normal.

"Maybe" it has something to do with the HKS wastegate actuator I'm using which is preset to not open until 0.9 bar ( 13 psi ) ????? ( internal wastegate on this turbo ) Maybe it and the valve don't like each other :chairshot

Anyway, no harm done and it was worth a try

[TokyoTaxi]

FAT32

If your using external wastegate dont go with the profec b spec 2 as tey such with external gates. Go a hks evc

HKS GT 25/35 w/internal gate on mine. Profec B Spec 2 OK for this ya recon ??

[nedb]

FAT32 - how much power does 2535 make on a RB20? When does it start to spool where on the RPM range do you get 1 bar?

[INASNT]

HKS GT 25/35 w/internal gate on mine. Profec B Spec 2 OK for this ya recon ??

Could be but theres alot of fiddely setting to play with with the profec b

[simark87]

Do you like jrdsports subtle way of trying to claim the turbotech is not as good as his powerup??

What he doesn't realise is that a few members have discarded the powerup and atomics and similar for the reliability of the turbotech!

What a joke, 12 pages of comparisons and then he posts that to try steal business. No evidence to support those figures, no evidence that the testing was even done! I find it hard to believe the guy would buy every boost controller on the market just to test them so he can make that post.

The powerup gets listed on ebay and bidding frequently ends with NO bids yet the turbotech sells 30 a week on ebay.

As a matter of fact I just got an email from a guy who recently purchased a powerup dual stage thats can't even hold 14psi!! It drops right back to 9 psi!!

This is his message cut and pasted right from the ebay email system:

Question from travfleur

Item: Turbotech manual turbo boost controller (4560217549)

This message was sent while the listing was active.

travfleur is a potential buyer.

"Hi, I currently have a power-up dual boost controller. Ive wound it up to 14psi but my car seems to lose boost once it hits 14psi back to around 9psi. Are you saying this controller your selling will fix this problem ??"

I have PM'd jrdsports about the tactic to try get some business but I doubt someone who goes to such a length just for a dollar cares much.

Reviews and over 400 sales and building speaks for itself..

Thanks everyone for your support and postive comments

Cheers

Mark

Until i see boost graphs, I wouldn't give it the time of day, and even then without an INDEPENDANT reviewer any claims one way or the other wouldn't hold a great deal of water.

simark87 keep doing your thing, majority of people on here are smart enough to ignore that sort of post, and as you say there's 12p of positive discussion here to back you up.

[CEF11E]

agree. Pfttt.

this pretty much prooves its a pile of sh*t

"GFB

Slight Boost spike mid range of about 1.22psi @ 16psi

1.95psi drop off at 7900rpm. Quicker spool than standard by 800rpm.

Adjustment alot more accurate.

Price: Afordable"

we all know a normal bleed valve will not spool up quicker than a controller with ball/spring operation.

pretty silly way of advertising a competing product. he could of atleast researched his compatition before trashing it!

Also

unless i see graphs i dont belive it either as i have personally tested, and infact i was the FIRST person on SAU to try this product and i compared it to a GFB and ithe turbotech was much better.

the guy selling them is the one trying to stake a claim in somone elses thread. Thats called Hijacking.

c. I THINK IT SHOUL BE A BANNABLE OFFENCE!!!! selling skyline owners dodgy products!
