what PSI is high boost defined as in mustangs?

 

Depends on the model and modifications really. My Cobra see's 20 lbs in the cold weather and 18 on hot days. On a stock GT or Saleen, 10 lbs is the very most you want to go because you can and will bend and break rods. On a PI mustang with forged and balanced internals... I would say 15-16 lbs before you over throw the valve train and or float a valve.

 

thanx danny

i think ill just keep it at 10psi (when asp gets finished makeing it for me)

BTW you still got a TB laying around

 

Nope... no TB's here. Sorry.
