idea: DIY fuel upgrade?

[WazR32GTSt]

ok so i am a big fan of the DIY concept. why pay $500 when you can whip something up yourself?

so i have this idea...

the concept of this forum is to bring these ideas together. and thankfully there are people here who can tell me to put these ideas back into my head and sit on them as they know what they are talking about...

so i have an R32gtst with 3" turbo-back, FMIC, rb26 cams, filter, 12-13psi, and remapped ECU

running that boost i keep thinking runnng lean might just be around the corner with the stock fuel pump

so i though of this:

is is possible to buy some sort of inline 'tap' ($2) from an irrigation supplies shop (eg kmart garden) and chuck this into the fuel return line. then slightly close the tap so that only 70% of the max flow rate can get back to the fuel tank?

from what i understand this should increase the pressure slightly in the intake line thus helping to prevent leaning out...?

would this work?

other repercussions? (ie starvation at the fuel pump? somehting else?)

just an idea...

cheers,

Warren.

It can only work if the pump can supply the flow to keep it at that pressure.. you are also going to increase the fuel right through the range.. so it will run rich and horrible off boost..

Best to just upgrade the pump, or T in two if you want a cheap way..

Well Wazza, you should be on the inventors... pattent that baby and spend your days in the arms of sexy babes.

Ever noticed when the tap is turned on at home, the initial pressure is higher than once it is running. That is because when the tap is off you reach line pressure. This is more obvious when you are on the end of a small pipe as the water slows to a trickle after the tap has been open for a short time.

What you need is "Constant" pressure, and enough volume... A fuel reg will adjust your pressure when you are at WOT (wide open throttle) or idle to the same level... OEM 2.55bar, then step to 3.05, and 3.55.

Now put the gardenea catalogue away and buy a decent fuel set up to compliment your already substantial investment.
