Im running twin to4e's on my car, just got the car up and running and this is the issues.



when I have the car running, and the IC piping connected, I the turbos start to blow air through the intake inlet on the turbos, causing oil to go with it, when I take the greddy elbow off I can feel the air pumping through the pipes and the turbos start to suck air in again and work normal. its almost like its soo much air for it to handle so it gets backed up

it sounds like something is causing your throttle plate not to open the proper amount. what happens at higher rpms?



btw, i run two to4e 46s and never had a similar problem so it probably is just a setup issue.

Either the compressor wheel to compressor housing clearance is really off, or you're running into some funky resonance in the intake piping due to the twins running.



Got pics of your merge after the turbos?
