	| Toobs wrote on Sun, 21 August 2005 17:02 |    Your idea's seem reasonable OC but how do you plan to control 3 throttle bodies? 
What if you replaced T1 with a wastegate with the boost feed coming from where you have R1? 
Maybe chuck in another wastegate with the spring removed instead of T2 (read: massif 1 way valve!!!) 
 
  |  
  
 
well... T1 and T3 are connected... since they basically just control the volume of the SC.... which by default can also control the pressure... i think this hooked to to a snazzy EBC (ie the ones that have RPM/TPS/Boost mapping) and a wastegate actuator, would work very well. i guess in theory this is basically what a wastegate is.. so yes   .. i was thinking throttle body for reduced flow restriction, but a wastegate, if properly sized would also work.. 
 
T2 is effectively a one way valve... and it may well be better to actually use one, if it could be made reliable enough.. there have been suggestions before of using a massive old AFM as a one way valve!! that could work too! 
 
thing is, none of this needs to work exactly.. since there is still the pedal conrolled throttle/s at the manifold, all this garbage is just a boost control system... and what's a few psi between friends    i guess in the long run, all this is meant to do is to stop and boost DIPS during transitions... 
 
i'll have to look into wastegates and actuators more

Then maybe you could invest in 1 x fly by wire throttle body for your T3 position and let the ECU control it. 
 
Seems like a lot of work for what you plan to achieve though... why not just bolt on your massif turbo and then use nitrous to get you going.  
  |  
  
 
well... i guess thats what the EBC will do... linear control of boost via the T1/T3 actuator...  of course if the ECU can do it also.. saves buying some colour screened crapp electronic box   
 
yes it is a lot of work... but no-one seems to have bothered to go down this path because it is "too complex/difficult"... i reckon i might just be the person to bother.... at least in theory
