Q

Yellow DV Spring [AC017]

A

The Yellow DV spring that is included with many of our popular DV kits is really meant to be a "Street" spring.  The spring is soft enough to quickly get rid of surge/flutter on fast spooling sensitive turbo systems, especially MAF cars, but you do have to be careful with how you apply it.  It is meant to help improve day-to-day driveability.  At times, it may even help on-throttle surge by being soft enough to keep the valve slightly open at the initial onset of boost at low rpms.

 

Port A+B:  It will hold boost to 45-60 psi in both push and pull

Port B only A to atmosphere:  It may limit boost to 20-25 psi in either push or pull.  If you find that this is the only configuration that works with your setup, then you'll need to apply more pre-load.

In any road racing, autocross or rally condition, it is recommended to use the standard spring.
