why doesnt the supra wastegate work like other stock turbo cars?
most other turbo cars will boost uncontrollably if you pull the pressure line that controls the wastegate. like over 30 psi!
but on a tt supra you only get 18-21 pounds of boost if you pull the pressure hose depending on weather conditions.
im still trying to figure it out, but i think it has everything to do with the weak wastegate actuator for the stock turbos. can someone explain why the stock wastegate behaves this way?
im asking because I am having a hell of a time getting my HKS EVC IV dialed in.
basically the evc wont make max boost (18-21 psi) unless the evc boost solenoid is completely closed. the only way to do this is by setting the evc to 30 pounds of boost. which will only make about 18-21 because it is pretty much doing the same thing as pulling the wastegate hose by sending no pressure to the wastegate.
i was wondering if anyone has figured out a way around this?
is there a way to modify the stock wastegate to function as on other cars?
i really want to take advantage of the extra functions of my EVC IV but cant do so unless I can get it dialed in properly.
any suggestions are appreciated.
thanks
