[JamiesTSI]

To help spool up a large turbo would I want to retard or advance the adjustable exhaust cam gear? Thanks.

Thanks for the info guys. Anybody have a good number to retard for Web street grinds?

On a side note did anybody read the latest issue of Turbo? On page 28 they talk about "considerably" advancing the exhaust cam. Is there a different situation with their set up that has them advancing there exhaust cams and DSM's retard theres?

It is a SR20DET engine in a 240SX

I've heard degree it about *2 for 272's. Thats for more low end torque.
