ima_slap_joO Posted January 7, 2012 Share Posted January 7, 2012 Hi, just wondering if there is a was to lower the standard boost level on the rb20. Since the car had exhaust and fmic fitted the boost has increased to 11psi at the lowest point, is there any way to lower this further?

Truffles Posted January 7, 2012 Share Posted January 7, 2012 (edited) Hi, just wondering if there is a was to lower the standard boost level on the rb20. Since the car had exhaust and fmic fitted the boost has increased to 11psi at the lowest point, is there any way to lower this further? There's no way to lower the boost below the standard actuator point (7psi at the actuator). why don't you want 11psi?

stig mick Posted January 7, 2012 Share Posted January 7, 2012 The stock r32 wastegate is 10psi Bit with a full exhaust it will usually got to 11-12psi So no you cannot lower it Why would you want to?

Truffles Posted January 7, 2012 Share Posted January 7, 2012 The stock r32 wastegate is 10psi You're right, my bad. Thinking rb25 actuator. Link to comment https://www.sau.com.au/forums/topic/387438-decreasing-boost/#findComment-6178470 Share on other sites More sharing options...
stig mick Posted January 7, 2012 Share Posted January 7, 2012 All good OP you could by an rb25 wastegate and stick that in instead that would lower your boost Link to comment https://www.sau.com.au/forums/topic/387438-decreasing-boost/#findComment-6178480 Share on other sites More sharing options...
mad082 Posted January 7, 2012 Share Posted January 7, 2012 as above, no you can't. but then there is no real reason to. it is perfectly fine to run that extra 1psi of boost. it won't cause any problems.

iruvyouskyrine Posted January 9, 2012 Share Posted January 9, 2012 If you want to run less boost just drive accordingly. Link to comment https://www.sau.com.au/forums/topic/387438-decreasing-boost/#findComment-6180397 Share on other sites More sharing options...

markdem Posted January 9, 2012 Share Posted January 9, 2012 place a spring over the actuator countering the effect of the internal spring. there is always a way Link to comment https://www.sau.com.au/forums/topic/387438-decreasing-boost/#findComment-6181384 Share on other sites More sharing options...
