Contour Enthusiasts Group Archives Forums Modifications Forced Induction Did he say twin turbo?

You see.. Compressor maps are for the compressor side of the turbo . .. Thats the other side. The side the "compresses" air. Im talking about the side that power the compressor side. The turbine housing. Even with a high a/r like .82 or so your still going to run into flow restrictions. 2 exducer bores are going to flow more then 1. Less TIP is good. Its not like these cars need anymore torque then they already have anyways. IHI`s like the ones found on the probe 2.2L would go great with these engines and would flow probably better then a t3/t4 with an a/r like .82 but without the .82 `s high boost threshold. Not to mention 2 waste gates to put air away and closer turbo to head design instead of piping it all together into one turbo. If spliting up exhaust pulses isnt benificial then why do turbo`s have dual imputs into a single turbine housing? Its the same concept by using 2 turbos. The energy doesnt get as "washed" out.
