clint84 Posted December 20, 2012 Share Posted December 20, 2012 Hi all, I have a question regarding the Blitz 'spec S' DSBC boost controller. Has anyone with a standard twin turbo used a spec S instead of the recommended spec R to control boost. If so, i would like to know how it performs or if it is safe for the sequential turbo setup. I am just hesitating installing the spec S DSBC into my car because the manual states that the spec S is not recommended for 'high boosting sequential turbo setups'..So my question is what is meant by 'high boosting'. If anyone could provide some opinions/advices it would be much appreciated. Cheers Clint Quote Link to comment Share on other sites More sharing options...

I'd go with what's recommended. Quote Link to comment Share on other sites More sharing options...
Alex Posted December 20, 2012 Share Posted December 20, 2012 Not the most helpful terms in the manual :-( OEM boost levels are rarely over 1bar...so at a guess I'd say its probably ok on bpu. If the actuator unit is the same on both then it's a processing/control limitation...which means it won't have the finesse and flexibility of the R system. It may also be the pressure sensor is lower spec so it cannot read above 1.5bar. The latter makes most sense for a reason why its limited. But where the limit is is up for discussion unless someone can find those details. Quote Link to comment Share on other sites More sharing options...
SPG Posted December 20, 2012 Share Posted December 20, 2012 Is the Spec S not a single Solenoid BC as apposed to the Dual Solenoid used in the Spec R Quote Link to comment Share on other sites More sharing options...
TBDevelopments Posted December 23, 2012 Share Posted December 23, 2012 yes same kit totally different solenoid. you can actually upgrade to a Spec R from the Spec S in the future if you needed to as its only a solenoid swap, but blitz do ask a premium for this upgrade Tim Quote Link to comment Share on other sites More sharing options...
