1. it will add some wieght.... my best guess would be less than 20lbs
2.it would add some complexity, but very little. The most complex part of the system would be the boost actuated exhaust "brake" in the down pipe.
[ http://i23.tinypic.com/1624jex.jpg ]3. No it shouldnt cause any une.ven load to the turbos.. as the exhaust manifolds would share the same amount of pressure and the intake tracks will have to join to join to prevent uneven boost pressure in the intake manifold.
4... ^^
5. The only part of the aft turbo exhaust that needs to be messed with is the passenger down pipe.. thats where the exhaust brake is placed that stops the flow and prevents the turbo from spooling.
6.It may... since only one turbo works for the majority of the time, but if i were to set up the boost limits, the passenger turbo would start spooling with the driver side turbo has hit 6-8psi. Which for turbo's the size of what you'd be running to make this setup worth while, they shouldnt be working very hard at all.
7. I dont see why it would heat the coolant any more than normal.. the turbo's dont work much outside of "normal". Here again this would be somthing that would have to be tested.
8. Boost control would work as normal. Internal waste gates with actuators than work like they do as they did.
9.From what i understand....
The benefit would be much larger than "normal" turbos that spool sooner than smaller "normal" turbo's...
I.E. GT2871RS's if setup in a single turbo configuration, that turbo would probebly hit full boost by... 3-3500rpms?? ( i honostly dont know)
but it would kill the engine in the 5K+ rpm for it would be too small, but as a pair they probebly wont spool till, 5-5500rpm's?? But would roxors in the 6k+ range, but they're almost too big. So the one turbo would spool very quickly in the 3K range and after it is well into boost, the second turbo would come in to give it the higher rpm flow that it needs.
Now thats just an example, if it actually worked that well the turbo size could be increased even more...
The supra's they're biulding the kit for will run a pair of 61mm turbos, where one is alittle small for that engine but two parallel would kill also. I hope that makes sense :eek:
10. it would be impossible to give actual numbers, for this is all just in thorey, but picture a stock TT power curve that doesnt curve, if setup right it would be a smooth seamless power arch much like that supercharger dyno....
