Fuel Starvation solution
Just wonder what all yeah guy use to stop fuel starvation.. For racing
I don't really want to go down the route of a swirl pot and I'd like to keep the busa fuel pump
What the best way to solve it baffled tank, sump in the tank, etc??

Cheapest route is to keep the tank full.
You may be lucky with some clever baffling but depends on how hard you corner and how the busa would react. Probably just kill power mid corner.
Swirl pot is really the only proper solution. This can be either in the tank or external.

Hi
In my kit car i used a standard steel tank modded slightly by drilling loads of holes along the bottom, and welding a very shallow oblong
"funnel" type base to the bottom of the tank with circular metal ring welded to it, this lead to a 2003 GRSXR1000 fuel pump that bolted
to the ring (sealed with a large "O" ring, the gsxr pump has its own internal Sump as you can see from the picture, after i installed i
never suffered from starvation again. and it had a integral fuel gauge too
Some people can never handle the truth and always try to shoot the messenger instead of taking an honest look in the mirror (its always easier to
blame another than to face reality), but secretly they wish they could grow a pair and be the messenger !!!

You say busa pump, in tank one ?
I run a in tank zx10 one and have no further problems, prior to that I ran a busa external pump had had intermittent starvation problems, even with a
swirl pot which as now been ditched also.

our standard tanks do have a baffle plate built in them.
if you are getting fuel starvation i would fit a swirl pot
thanks danny

its quite bad, if i get down to half a tank I suffer from it ...
maybe the swirl pots the only answer
Turns it into an expensive job
low pressure pump,
high pressure pump
swirl pot
fuel regulator
fuel filter,
Tank modified
and wiring for the lot too

It's your call, I had lots of starvation problems, I thought it was an injector problem at 1st but it wasn't, exactly same as you also 1/2
tank made it worse throwing a red herring.
I purchased a zx10 in tank pump, had a small sump made in fuel tank, run a direct feed to fuel rail with no return, had zero problems since and I
regulary do 1 hour plus stints on track.
Your call, trust me it will work.

a sump in the tank might be the right option first

with afew of our cars we have made a swirl pot with the hayabusa pump built in it.then it save you the cost of regulators and other things.but then
you would need a different tank so its up to you
thanks danny

think i found the a solution
EFI Fuel Pot / Collector
For car installations using fuel injection, Rilltech has a custom fuel pot available to ensure you get every last drop of fuel in your cell. Even
fuel cells with collectors can have as much as a gallon of fuel left in them when fuel pressure starts to become erratic.
This pot ensures that does not happen. A small rotary scavenge pump keeps the pot filled from the fuel cell, and a high pressure pump feeds the
engine. This pot can accept stock Suzuki/Yamaha/Kawasaki pumps, and many aftermarket pumps internally, or you can plumb the output of the pot to an
external fuel pump
just need to add a lift pump
