hodge Posted February 16, 2006 Share Posted February 16, 2006 I have an electronic boost controller fitted but it is only funning the front turbo is it possable to get a second boost control valve and to run the second turbo and piggy back it the the 2 wires on the original valve so I can control the boost pressure on both turbos.

Jake Posted February 16, 2006 Share Posted February 16, 2006 You only need it connected on the one turbo anyway. Adding another would achieve nothing. Link to comment Share on other sites More sharing options...
hodge Posted February 16, 2006 Author Share Posted February 16, 2006 Does it matter which turbo its connected to. My idea was so I could raise and lower the pressure on both turbos. Well lower mainly. Have you ever took your car anywhere for work done and you just know they have been out in it thrashing it about thought if I could turn the boost right down sort of a valet mode if you know what I mean.

Jake Posted February 16, 2006 Share Posted February 16, 2006 You can't connect it to the second turbo. Your car only has one wastegate, which is on turbo #1. When the second turbo is boosting its automatically at the same boost level as turbo #1. Link to comment Share on other sites More sharing options...
Steve Posted February 16, 2006 Share Posted February 16, 2006 Also you can not lower it below stock levels Link to comment Share on other sites More sharing options...
hodge Posted February 16, 2006 Author Share Posted February 16, 2006 Fogive my ignorance. Ive only had my supra about a year and have just started with power upgrades. So if both turbos run off the same acturator am I still right to still block off the centre pipe on it with my boost controller solnoid vbetween the top actuator pipe and conpressor housing.

Jake Posted February 16, 2006 Share Posted February 16, 2006 The boost controller is plumbed in between the top of the actuator and the first turbo. The hose that goes to the bottom of the actuator needs blocking off too. Link to comment Share on other sites More sharing options...
hodge Posted February 16, 2006 Author Share Posted February 16, 2006 Does the actuator have 2 or 3 hoses. Link to comment Share on other sites More sharing options...

If your worried about garages thrashing your car. record the millage and tell them that its not to be driven without you being there. Sounds harsh but that what I have done and works fine.

Chris Wilson Posted February 17, 2006 Share Posted February 17, 2006 You can't lower the boost with a boost controller down from the wastegate spring pressure, it's a very common misconception, so save your money. Take it to a garage that won't thrash your car around! I don't actually LIKE driving customers cars, so you'd have to explicitly TELL me to drive it! That's not to say I CAN'T thrash it if you really want me to, but there's little need unless you have some odd, specific problem. Link to comment Share on other sites More sharing options...
_Rob_ Posted February 17, 2006 Share Posted February 17, 2006 Also you can not lower it below stock levels sorry to hijack, but is that true? just wondering cos it sounds like a good idea. whats the science behind, how come it wont go lower than stock?

Chris Wilson Posted February 17, 2006 Share Posted February 17, 2006 They will only bleed off boost to the wastegate, fooling the `gate into thinking boost is lower than it really is (so boost goes UP). Probably the commonest misconception about boost controllers there is. Link to comment Share on other sites More sharing options...
Ian C Posted February 17, 2006 Share Posted February 17, 2006 Boost is controlled by the wastegate bypassing the exhaust flow around the turbo. When the wastegate is fully open, that's the maximum amount of exhaust gas it can bypass and the resulting turbo boost pressure is your minimum boost. The boost controller raises boost by making the wastegate open less and therefore bypass less exhaust gas, but it can't make it open wider than "fully open" so it can't lower the boost. -Ian Link to comment Share on other sites More sharing options...
tango Posted July 25, 2006 Share Posted July 25, 2006 The boost controller is plumbed in between the top of the actuator and the first turbo. The hose that goes to the bottom of the actuator needs blocking off too. What happen or different if the bottom of actuator is not blocking off? cheers Link to comment Share on other sites More sharing options...
