Supra_Nish Posted April 4, 2005 Share Posted April 4, 2005 Found a very good price on one of these, but not sure if its the spec s or the spec r. Apparently according to seller on the front it says: "Dual SBC dual Solinoid Boost Controller". Am i right in thinking this is the spec r? Also, if it is a spec s, is this suitable for the supe? I plan to run around 1.4 bar at some point. Thanks in advance! Pic attached. Link to comment Share on other sites More sharing options...
imi Posted April 4, 2005 Share Posted April 4, 2005 Mine doesnt say Spec R or S either....perhaps its an older model.. Link to comment Share on other sites More sharing options...
Supra_Nish Posted April 4, 2005 Author Share Posted April 4, 2005 Hmm TBH i'm not fussed if it is a new/old/spec s/spec r model, just want to be sure it will work up to and past 1.4bar. So assuming worst case, and it is a spec s, does anyone know whether it can do the job? Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 4, 2005 Share Posted April 4, 2005 yeah the blitz EBC's are cool Link to comment Share on other sites More sharing options...
D3xt3r Posted April 4, 2005 Share Posted April 4, 2005 If its dual Solenoid its good to go. The Spec S is Single Solenoid which I wouldnt take for anything over 1 bar. Link to comment Share on other sites More sharing options...
Supra_Nish Posted April 4, 2005 Author Share Posted April 4, 2005 Yeah after much googling found the spec s can only handle up to 18 psi. A little too close to the limit for me. No visible markings between the two, as far as i can tell the main difference is the size of the solenoid. I'll see if he can stickhis head under the bonnet! Thanks guys, much appreciated.

GeordieSteve Posted April 4, 2005 Share Posted April 4, 2005 Would it do any damage using over 1bar on the spec S? Link to comment Share on other sites More sharing options...
Supra_Nish Posted April 4, 2005 Author Share Posted April 4, 2005 Would it do any damage using over 1bar on the spec S? I'm really not that technical mate. All i know is its intended for use up to 18psi, i guess maybe past that the solenoid can't handle the pressure/do its job properly? Link to comment Share on other sites More sharing options...
GeordieSteve Posted April 4, 2005 Share Posted April 4, 2005 Don't see why it would make too much difference but I creamed a turbo a few month back with a spec S at 1.2/1.3bar Link to comment Share on other sites More sharing options...
Jake Posted April 4, 2005 Share Posted April 4, 2005 I plan to run around 1.4 bar at some point. 1.4bar? Not on J-spec ceramics I hope. Link to comment Share on other sites More sharing options...
Supra_Nish Posted April 4, 2005 Author Share Posted April 4, 2005 sounds ominous, perhaps it coudn't control the boost and let it spike to something nasty? Though they seem to have some warning features built in which should have cut things down. Link to comment Share on other sites More sharing options...
Supra_Nish Posted April 4, 2005 Author Share Posted April 4, 2005 1.4bar? Not on J-spec ceramics I hope. No on hybrids. Even then 1.4 is a loooong way off. 1.2 is likely the max i'll take them to but would rather have the flexibility at a later date. Link to comment Share on other sites More sharing options...

Gazboy Posted April 5, 2005 Share Posted April 5, 2005 I ran 1.1 on the MR2 with the single one, no probs, had a 1.2 bar overboost too. I'm getting a dual sol one next month for the Supra (was thinking of the T/G profec E01 thingy, but it just screams "break into my car and pinch me").

lpher Posted April 5, 2005 Share Posted April 5, 2005 Ive spoken to Dusty at MVP and he clearly states that the Blitz SBC Spec S can handle 30psi / 2.1 bar... Anyone else care to shed some light on this subject? Link to comment Share on other sites More sharing options...

Anyone else care to shed some light on this subject? I've seen the figure 18psi as being the recommended upper limit on various websites. i.e. http://www.jscspeed.com/universal/boostcontroller/blitz_dualsbcs.htm Whether these are proven limits, or the tuners own recommendations i dont know. Happy to be proved wrong as the spec s is much cheaper. Anyone out there with a spec s def running more then 1.2 bar? Link to comment Share on other sites More sharing options...
normore1 Posted April 6, 2005 Share Posted April 6, 2005 If it's truly a DSBC (Dual Solenoid Boost Controller) then it should contain a dual solenoid actuator. Unfortunately it appears that Blitz marketing choose to replace the SSBC (single solenoid) by pairing the DSBC controller with a single solenoid actuator under the hood. The only way to tell the difference is to visually check the solenoid. The single consists of a solenoid (similar to a VSV) in a brass frame while the double is enclosed in a larger plastic housing. The good news is that either will control boost up to 1.5 BAR. The only supposed advantage of the DSBC Spec R is faster response. Link to comment Share on other sites More sharing options...
lpher Posted April 6, 2005 Share Posted April 6, 2005 I actually ordered this a while ago from Dusty at MVP, but fear ive ordered the wrong unit... But i am a bit reluctant to return it...(mostly cause it will takes ages to get it in and out of customs etc, here in Norway) until i get it confirmed that it wont hold 1.2 Bar. As this is the absolute max im going to using. (its my everyday car) I got a breif answer from Dusty that it can hold 30psi / 2.1 bar...as i stated earlier in this thread...but as i got the merchandice today...i had a look in the manual...and it says that the Spec S is not recomended for large turbos, twinturbo and sequentiali setups... So naturally im a bit worried here normore1: It seems your right regarding its name...the box it came in says "BLITZ Dual-SBC Spec S" ...and its packaged with the small, single solenoid yes...(the one with the brass frame) Link to comment Share on other sites More sharing options...

So naturally im a bit worried here QUOTE] The single solenoid probably isn't suitable for a large single. As far as twin setups the manual is refering to twins in parallel configurations with two wastegates like on a V6. For the Supra the twins act in sequental mode and look like a single when they go parallel. There is only one wastegate so the system works.

That makes sense ...in it goes then i guess Me and a mate are going to install the DSBC and a FCD this weekend...and im needless to say really excited about how it turns out Link to comment Share on other sites More sharing options...
