Guest INASNT Posted May 21, 2003 Share Posted May 21, 2003 After a bit of research i have narrowed it down to 2 ebc which i am gonna upgrade from the shitty turbosmart 2 stage bleeder I need some comments as experiences with either unit good/bad and features.

turbomad Posted May 21, 2003 Share Posted May 21, 2003 I can recommend the Profec B, on the dyno with the boost displayed digitally in remained within 0.1 of a psi to the set limit. The low setting is good for situations where a bit of wastegate creep is needed eg. in the wet or heavy traffic, you won't get full boost at light throttle, but in high there is no wastegate creep at all as I can have 12psi at less than 30% throttle.

predator Posted May 21, 2003 Share Posted May 21, 2003 ProfecB gets good wraps compared to the more expensive units around. One of the mags did a comparison somewhere, i am sure you can find reference to it on the net. No rice factor but it does what it needs to well.. the "sharpness" knob is a useful one in my car.. basically how it was explained to me is that it it controls how tightly it holds or releases the wastegate. To me if i turn it to "sharp" it seems to spool up a little faster and "crisper" if that is a correct way to describe it... so i play with it on the road and adjust 25% either way depending on what i want. Seems to do that, however can also be used to reduce spiking or boost dips on the dyno Link to comment https://www.sau.com.au/forums/topic/16426-trust-profec-b-or-blitz-dual-sbc/#findComment-337283 Share on other sites More sharing options...
DREMEN Posted May 21, 2003 Share Posted May 21, 2003 I have been recommended Profec B by many people So thats the one I will be getting Its just a shame that it doesn't have a digital boost read out built into it, then it would be perfect Link to comment https://www.sau.com.au/forums/topic/16426-trust-profec-b-or-blitz-dual-sbc/#findComment-337539 Share on other sites More sharing options...
Jay95R33 Posted May 21, 2003 Share Posted May 21, 2003 I've seen a Profec B installed in the ashtry of a R33 GTS-t !!! They are that small - I love the stealth thing. Plus making them stealth means there's less chance of your car being broken into Anyway - a bit off topic - sorry Link to comment https://www.sau.com.au/forums/topic/16426-trust-profec-b-or-blitz-dual-sbc/#findComment-337587 Share on other sites More sharing options...
predator Posted May 21, 2003 Share Posted May 21, 2003 yes, stealth is good..you can tape up the LEDs and stick it anywhere.. its not like u need to adjust it that much anyway. u just set a low boost point, high boost point, which one u want selected and leave it be.

Guest INASNT Posted May 21, 2003 Share Posted May 21, 2003 no1'c going to give the blitz a good comment? i was actually leaning towards that 1 Link to comment https://www.sau.com.au/forums/topic/16426-trust-profec-b-or-blitz-dual-sbc/#findComment-337767 Share on other sites More sharing options...
rob77 Posted May 21, 2003 Share Posted May 21, 2003 Myself and 3 other guys in perth have the blitz sbc type s, its got 5 boost settings as opposed to only 2 on the profec, it reads boost in bar so it acts like a boost gauge, unlike the profec. Quite simple to fit and setup, holds my boost at 12.5psi very well except when the valve timing kicks in and it drops to 9psi, but thats something to do with my ecu.

turbomad Posted May 21, 2003 Share Posted May 21, 2003 Pred, the BALANCE knob is actually to adjust the boost from rising or falling as rpm rises, so starting from the middle point if boost rises with rpm turn the knob towards the SHARP side and if boost falls with rpm then turn towards the MILD side.

rob77 Posted May 21, 2003 Share Posted May 21, 2003 gonna run more than 20psi of boost? if so you need the dual solenoid, if not dont bother with the extra expense.

hungry6 Posted May 21, 2003 Share Posted May 21, 2003 i'm using a blitz dualsbc for a few years now, at fiirst no one really knew how to set these now after trial and errors and tunning and details from net. once it is set up properly it is a devastatingly accurate and powerful controller. nothing else i've used comes close. it has digital boost reading so u can get rid of the 50mm guages and , it has a max boost memory and a few other nice function.

Gester Posted May 21, 2003 Share Posted May 21, 2003 I'm having a problem with mine. It's just started ticking. I took it to the mechanic he said it was just the solenoid ticking but that its not set optimally and apparently alot of power is being lost and more fuel is being pumped to compensate, due to it not being setup well. What kind of settings should I run on the blitz ebc? I think I have it set at 50 gain and .8 bar it gives 12psi on a analogue meter. Also since this was in my spool time is alot longer a bloody excel can beat me over 30m heh. Even if you have a different setup what kind of settings do other people use for optimum performance?

MRK25T Posted May 21, 2003 Share Posted May 21, 2003 I've got a profect b on my car Inasnt, i've just posted the dyno graphs in the thread about my powerFC problem that you've been reading. It has the boost on it and as you will see it kept dead on a single boost figure.

SeriesIIGTST Posted May 21, 2003 Share Posted May 21, 2003 For what it's worth, I've just fitted a Spec S Blitz DSBC and so far, i'm blown away with the accuracy. Also love having the peak boost and real-time boost readout as i'm not one to go putting guages all over my car.

Gester Posted May 21, 2003 Share Posted May 21, 2003 What kind of settings are you using SeriesIIGTST? I'm lost on how to use it. heh I just dont have much of an idea. When you start getting into Gain and Ratio I get confused. What type of boost are you running on your S2? I run 12psi dunno how I set it but thats what a seperate boost gauge reads.
