08 1441 Fuel Pressure Increase
« on: January 07, 2009, 10:05:53 PM »
Is there any HP gains or any advantage to increasing the fuel pressure for a 08 1441 Busa? If so, how much should it be increased for best results?

No need unless you are running out of fuel hp gains i dont see any.  The higher pressure might help some with atomization.

I ALWAYS up the fuelpressure FIRST.

It helps with atomization and if the PC fails you can "limp" home on fuelpressure alone.
I dont know what I am talking about but I do know that I am right :)

How do you increase and what do you increase to? Do you increse the stock fuel pump or what?

You crush the regulator ever so slightly. A few members here on the site will do it  :thumb:
