Thread: Gaining HP through fuel pressure

I was reading a article on a Honda boy site and noticed they recieved a gain in HP with a simple fuel pressure adjustment. Does that work the same way for our cars? If so how much should I raise the pressure? What kind of gains (if any) will I recieve.

eh what kinda numbers are they reporting they are gaining? adjusting your fuel pressure can give better fuel pressure and allow you fuel injectors to reach more whp without needing bigger injectors.

but as far as gaining hp i doubt its anything impressive.

Adjusting FPR is a key point in tuning. Now just by bumping up the FP does not mean it will be automatic HP. There is a lot more that plays into it that just that.

also you are going to need a fuel map that is going to be 4 bar if you are looking to upgrade to 4 bar, you cant just adjust the fuel without having a map that is going to be at hte right fuel pressure, if you do, do that you will end up with a really rich fuel map

Honda = MAP
Nissan = MAF

'Nough said.

fixed that for you.

atomization?

whats the site u seen this at?

If the engine was leaning out a fuel bump should show you some gains

In the SR20DE N/A game is kinda different, the last time I hooked a wideband to a stockish car the A/F at WOT was around 11.8, you could even gain a few hp leaning it out close to 12.7 or something

^ is this na or turbo
