onephatz Posted June 9, 2005 Share Posted June 9, 2005 I'm running a 280z with a stock turbo motor w/intercooler, w/dsm450's, w/ megasquirt. problem is that my manual boost controller doesn't respond fast enough and I end up spiking to above 21psi. mega squirt doesn't like this and tells me so in a very bad way when it happens. I want to be able to run 15-20lbs of boost out of the turbo but if i set the controller to high it spikes about 21 and we have problems. if i set it where is doesn't spike over 21 it settles down to around 12lbs which is unaccpetable to me. I have an extra wastegate acuator and was wondering if I could take it apart and add a bigger spring to have the faster response and not have to use the boost controller. it's the stock t3 turbo with the stock wastegate actuator. thanks jesse Quote Link to comment Share on other sites More sharing options...
Clifton Posted June 9, 2005 Share Posted June 9, 2005 Use a stiff spring to pull on the WG flapper. A small bracket and threaded rod is all that is needed and a spring. It is more reliable and dead accurate. Quote Link to comment Share on other sites More sharing options...
VinhZXT Posted June 10, 2005 Share Posted June 10, 2005 What type of MBC are you using? The bleeder type or the ball & spring (hold boost and release) type? Quote Link to comment Share on other sites More sharing options...
