parko Posted February 13, 2011 Share Posted February 13, 2011 hey guys,wonder if anyone could shed some light on what i can do to raise me boost pressure.i fitted a new RB CT9 turbo not long ago, along with a manifold,induction kit etc., and putting the decat on today but it will only boost top a max of 0.24 bar according to the boost gauge and turbo timer. running great just not boosting as she used to i have a japspeed manual boost controller i can fit but have left that off as i am not sure if i want to fit it, heard the manual BC's aint great but cant afford a EBC just yet.any ideas on why its boosting so low? could it be on a default setting or anything or more lightly to be mechanical?also what bar could i reliably run at with a blitz induction/ dual turbo timer, zisco compact mani, RB CT9, japspeed exhaust, autobahn hoses, rocker breather soon to be catch can, no fmic though so i am not sure what to run it at. any suggestions would be very helpful!Thanks GuysParko Quote Link to post Share on other sites
GT Phayer Posted February 13, 2011 Share Posted February 13, 2011 i had a low boost problem and it was a slight spit in an intercooler pipe doubt this is whats wrong with yours but thought il suggest it to check all hoses and piping Quote Link to post Share on other sites
Stulet-GTT Posted February 13, 2011 Share Posted February 13, 2011 Are you useing the standered actuator???I put the standered actuator on to my hybrib when i first fitted it an it would only boost about .2, once i got an adjustable on there i wound it up to .8 Quote Link to post Share on other sites

Socks Posted February 13, 2011 Share Posted February 13, 2011 the stock actuator will just allow the wastegate to open matey... get yourself a HKS jobbie and remember it wants to be tight on the connector so u have to put a bit of pull on it to et it on and go from there dont let it worry u, easy fix Quote Link to post Share on other sites
parko Posted February 13, 2011 Author Share Posted February 13, 2011 oh would you recommend fitting a fuel pressure regulator if i am winding the boost up a bit? Quote Link to post Share on other sites
