i've been told by a couple people that if you turn the pump up too much that it is hard on it,and it will eventually go bad.is there anything to this,or is it bullshit?is there anything you can do to one to shorten it's life?

 

I, too have heard something along those lines and have a few buddies with 12v's that want em turned up a bit but are worried about hurting things. So lets get some clarification before i go tweaking things.

 

AS YOU CAN SEE IN MY SIGNATURE I HAVE ALREADY,I JUST WONDERIN IF I SHOULD EXPECT TROUBLE.

 

as long as you get fuel to the p7100 it should be fine, if you don't keep goop fuel press thats when they start to blow up ... ask me how I know

 

HOW MUCH PRESSURE IS IDEAL?

 

bosch says 17-22 at idle and 25-35 at 2500 rpm with no load on the motor. when I finish my engine build Im gonna run 40 psi all the time with my air dog 150

 

"blow up"? Dave you talking about sticking a rack?

As for too much FP. Jamie Wood on here is running 40 PSI at idle and 80 at full throttle with no issue. Ive see dyno graphs of hp at 40 and hp at 80 on back to back runs they had 1 - 2 more hp.

 

no I ment blow up ... as in I removed the dv and was picking pecies of the #5 plunger out with a pair of needle nose pliers. I'm not 100% sure how it happened cuz I had no fp guage at the time but I think my fuel press was low and caused the plunger to heat up expand and blow up.

 

OUCH!!

 

yep took it to a pump shop and the worker there said he never saw a pump go like mine did, I ended up buying a new rebuilt pump. this turned out to be a $1200 mistake that will NEVER happen to me agian
