abtin90 Posted October 25, 2014 Share Posted October 25, 2014 A lot will depend on the compression. Are you running a standard engine or have you lowered the compression with either a thicker headgasket or TT pistons? Link to comment Share on other sites More sharing options...

Mk4Gaz Posted October 26, 2014 Share Posted October 26, 2014 Probably best starting with a 7psi spring, and then using a boost controller to raise it to your desired boost setting. I don't know what boost level most folk run, but I'd assume more than 7psi Link to comment Share on other sites More sharing options...
champwhite4l3x Posted October 26, 2014 Author Share Posted October 26, 2014 Would i need to buy like 3/4 springs for when i go mapping then? Link to comment Share on other sites More sharing options...
Morzy2k5 Posted October 26, 2014 Share Posted October 26, 2014 No,if you fit a 7psi spring as said above..and then fit a boost controler that will adjust boost accordingly...no need to keep opening the wastegate and messing about with the springs.

Mk4Gaz Posted October 26, 2014 Share Posted October 26, 2014 All the wastegate spring does, is set your minimum boost level. Using a boost controller will then allow you to go up from that Link to comment Share on other sites More sharing options...
