maxing fuel pressure gauge bad?

[mike1999]

I actually have two questions:

first i only bought a 100 psi sweep fuel gauge when i installed my turbo kit now when its floored the gauge maxes out is this going to damage the gauge any?

and two in higher rpms the boost creeps 5 psi up to 10 psi and its only supposed to reach 5 or 6 psi is this going to damage my engine?

thanks

Yes it can damage your motor, expecially since its a N/T. Port that turbo to see if it helps or you can run an external wastegate. Are you on stock internals? If so I would not run more than 6psi. Also since your running boost im guessing your completely tuned right? If not I would not boost anything at all.

well its a hahn turbo system and they told me that i am going to get 6 psi if im lucky it has a 5 psi actuator on it which came with it. its a big 16g no real tuning except fuel pressure really because my bumper was getting covered in carbon so i leaned it out a little other than that though there arent really too many dynos around my area sooo thats probably not happening too soon. horsepower wise would the boost creep give me any gains, i would imagine it would but im no expert at 17.

It will give you more power untill it blows up

mmmmm thought so..... how would porting the turbo help with boost creep? I also dont have a catalytic converter and i have a highflow muffler

boost creep is the result of the wastegate being to small to flow enough exhaust "around" the turbo as flow increases. So by porting the wastegate it flows better and is no longer a restriction. I hope that makes since to you.

yes perfect sense thank you for the clarification
