turbo 400 line pressure

[karolko]

I am about to get a turbo 400 built for my GN and i was wondering if you guys could shed some light on this for me and others wondering the same thing.

I have heard 40 psi and i have also heard 60psi.

Could someone explain which is better and also how to determine the maximun pressure allowable on the thrusts before damage begins to occur.

Thanks alot,

Adrian

The 40-60 psi you are refering to is the converter charge flow pressure measured in the converter cooler circuit. Teh range you specified is generally OK. Any more is a waste and can potentialy wear the crank thrust bearing.
For actual line pressure measured in the drivers side plug in the case, you can tolerate anywhere from 160-200 PSI in a manual VB and t-brake application. I personally like it around 200 PSI. More is not always beter. There is a lot of discussion in this forum on these topics and would be worth doing a search.
