gurteen0 Posted April 30, 2016 Share Posted April 30, 2016 Evening all I just put on all the bits for a bpu set up but boost is sitting at 0.7/ 0.8 mark I've done fcd, plugs, decat, Full exhaust, filter, just wanted to know if I've miss something along the way any help would be great oh it's a tt manual by the way Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted April 30, 2016 Share Posted April 30, 2016 That's actuator pressure. You need to fit a boost controller, to raise the boost Quote Link to comment Share on other sites More sharing options...
gurteen0 Posted April 30, 2016 Author Share Posted April 30, 2016 Oh okay thanks mate I thought by all the bits that it went above the psi than u use the exhaust restrictor to bring it down to 1.2 Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted May 1, 2016 Share Posted May 1, 2016 No, the restrictor ring helps to stop the turbos over spooling bud You can achieve your desired boost level, by carefully selecting the right sized restrictor gasket. But, it would take a fair amount of trial and error, so most folk just fit a 2" restrictor gasket, and use a boost controller to raise the boost. By using an electronic boost controller, you can also play around with the gain setting, to help the turbos spool faster Quote Link to comment Share on other sites More sharing options...
ianhid Posted May 1, 2016 Share Posted May 1, 2016 Yep, j-spec without the ring will just run away past 1.6bar, at which point you're driving a grenade... Quote Link to comment Share on other sites More sharing options...

If it's a j-spec then increasing the diameter of the hole in the restrictor ring will make the exhaust more free flowing, which will raise the boost pressure. On a j-spec I'd use a restrictor ring to cap the peak boost pressure at 1bar then use a good quality electronic boost controller to then raise the boost to 1.2bar. If it's a UK spec it will need a boost controller to raise the boost pressure. Quote Link to comment Share on other sites More sharing options...
gurteen0 Posted May 1, 2016 Author Share Posted May 1, 2016 (edited) It's a j spec I've put a whifbitz 2" rr on it Edited May 1, 2016 by gurteen0 (see edit history) Quote Link to comment Share on other sites More sharing options...
