Fuel Regulators

[Waldo]

hey would a SArd rising rate fuel regulator do anything on a stock r32 rb20 fuel system........would i expect any power gains or anything

You mentioned stock fuel system, what other modification's have been done to the car ? Power gain's none. This depends on the boost pressure that you are running aswel to determine rich or lean. Low boost you won't need regulator as the stock system can handle it fine. Anything over 12psi you need to start upgrading parts.

Eg:

You really need to upgrade you'r fuel pump first before a regulator as the new pump alone will up the pressure. Then the regulator can be installed

You can expect it to run rich, meaning you'r fuel guage will go down twice as quick

I agree 12psi + u need a rising rate and pump if you want it to last....

U could do a dodgey and not use either but the rising rate reg looks sweet with a little gadge hanging out the side also. I use sard as malpasi was a little touchy in my last sky.

The sard one was litle 30 bucks more but worth it as it took far less time to set...
