I have an 87 TII engine, and i just turned up the boost, but, the funny thing is, i was hitting 10, 11, sometimes 12 psi without hitting a brick wall or even going lean at all. How do you know if you are hitting fuel cut. I do NOT have a fuel cut defender. Thanks alot.

 

generally you should feel an almost cutting out feeling with a sharp noise that goes along with it.. Don't find out the hard way, that turbo is on death's door at 12psi...

 

I was told that fuel cut was at 8.5 psi.....

im running about 9 right now. No lean outs, goes pretty good. even if it does creep to 11 lbs, it doesnt cut out or anything.

 

you should feel a fuel cut... no fuel in the rear rotor is somewhat noticeable... ever driven a car with a blown motor?

 

Hmm, nothing like that. What could be different about my car? Does jspec computer not have a fuel cut? I KNOW for sure it has no fuel cut defender. At about 9lbs and over, i notice that i dont gain power anymore, but i dont lose it. Im pretty sure im driving the compressor out of its efficiency range at that level. 8 lb seems to do just right.
