kidsen336 New Member 11 Member For: 9y 8m 10d Posted 24/07/15 01:41 AM Share Posted 24/07/15 01:41 AM Hey guys picked up a ba ute with bf motor and drive train bout a month ago and m having issues making good power. It has all supporting mods to make easy 350kw but only just pulled 300kw seems that boost cant be increased over 15psi and bleeds back to 12psi it has a eboost street ebc. No matter how much we wound into it on the dyno boost would not increase. Im thinking actuator cant hold the wastegate closed. Any other idears guys any help would be appreciated.Sent from my SM-G900I using Tapatalk Link to comment Share on other sites More sharing options...

I gather he was trying to fix the same issue. it has stock turbo with stock actuator ive been told the flapper mod has been done. All I can think of is that it hits 15psi n the gate opens cus the stock actuator cant hold any more. And since it does this at 55% on the boost controll and even when wound to 99% nothing changes the actuator has to be the problem. The eboost controlls boost under 15 psi perfect so its working fineSent from my SM-G900I using Tapatalk Link to comment Share on other sites More sharing options...

I want it to hold 17 to 20psi right through rev range and make 350+kw wich will b easy if I can sort this boost increase issue.

Skids4kids in the mid....not the bum like some Member 609 Member For: 11y 10m 3d Gender: Male Posted 25/07/15 11:37 PM Share Posted 25/07/15 11:37 PM Having the port larger on a stock actuator means the actuator has even more force on it at same boost due to the larger flapper having more gas pushing against it.
