dat240zg Posted May 11, 2005 Share Posted May 11, 2005 Alright...I'm needing a little input from the wastegate gurus here. I'm in the process of purchasing a TiAL 38MM wastegate and need to select my spring (.4 .5 .6 .7 .8 .9 AND 1 BAR ). I know that everyone has their opinions, so I'm hoping that some of you will share yours with me. My current setup is L28T, stock electronics, TB upgrade, IC, T3/T04E, 450cc injectors, ProfecB II, etc. Any thoughts? Bryan Dat240zg Quote Link to comment Share on other sites More sharing options...
Clifton Posted May 15, 2005 Share Posted May 15, 2005 Go with the stiffest one you can safetly if you plan to run higher boost with 100+ octane. If you run a 8 psi spring, and turn it up with a boost controller it will have a difficult time holding steady boost at higher rpms if you run over 18 psi. I tried it. I ended up running a 1.2 bar spring as I will never run less than 20 psi. Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted May 16, 2005 Share Posted May 16, 2005 Since you are still on the stock electronics, I would probably go w/ a 12-13 psi spring, so maybe a .8 or .9 bar. I imagine you will be running a boost controller of some sort for higher boost levels. Quote Link to comment Share on other sites More sharing options...
