Hello VolvoForums, I am on the verge of buying an S80 T6. But have found out something that I was unaware of... The turbo set-up is sequential. Someone on here also said the turbos were of different sizes!? I had planned on modifying the car, but some of what I hear conserns me, and I am new to Volvos, and I cant find any schematics of the car. I see some people do have boost gauges, and Volvo parts sites sell Blow Off Valves, so I assume people turn up the boost on these S80's?! Wut do you all do? Run two controllers one on each waste gate? Is this set up like a the Supra set up?

 

Both turbo's are the same size.
You should be able to go bigger if you can find the room.
It only has one Electronic boost control valve so both should work the same time.

 

TY for the info! So the ECU wont act up with manual boost controllers?

 

Plus, does anyone make a piping kit for this car?

 

I haven't tried on the S80 myself to answer 100% for sure. But I wouldn't think it would if you hooked it up properly.
Make the computer think it is still connected.
I have never seen any piping avalible for it as of yet.
