surge tank

[Dangermouse]

Whats the advantage of having a surge tank?, and how does it vary depending on the size of it?

[mokompri]

stops fuel starvation occuring during hard cornering and acceleration

there is no advantage in having a larger or smaller one, you just need to make sure the low pressure pump feeding the surge tank outflows the high pressure pump feeding the injectors, so that in effect there is always fuel in the surge tank

500ml-1L will be fine

it also helps when you have an empty tank and take a corner real hard!

so in effect it really is only sutible if you are running bigger injectors, turbo gear etc.

if your just riding in a stock turbo, the advantage would be minimal, or does it still help?

nothing to do with bigger injectors and other mods.

If you drive your skyline around a track or do any mountain runs. As you get lower on fuel. The fuel that is in your Fuel tank splashes around more and more with each turn or sudden hit of the acclerator you do. If you get really low and then hit the gas all of a sudden your fuel pump is sucking in air not fuel.

What a surge tank does is gives a compensation for this time.

Normal fuel pump fills up the surge tank. That is now its job

Surge tank feeds your new external fuel pump that is feeding the engine its fuel.

You go hard around the turn. Fuel in fuel tank gets pressed hard against the wall, Fuel pump can't get any fuel to your motor. BUT the surge tank is nice and full with 1L of fuel in it. You take off and become the next king of the track.

Its not a necisity. But if you do let your fuel drop below say 1/4 and you are at a track day it will help.

hope that helps

Yup, I'm running stock turbo with every other mod bar the turbo and when I corner hard on with semi compounds at Philip Island my car choaks and spluters. Time for me to invest in a surge setup.

[GRUNTN]

truly these things are a piece of mind not realy a mod and think all should seek

[adznight]

Piece of mind? No I don't agree there, when you starve a cylinder and melt something becuase your getting surge I bet you wouldn't think that but I do agree that it's a very unnecessary mod unless you require it as it provides no performance benifits.

[GRUNTN]

well i thought u might have tough internals but with stock turbo, fuel system - a surge would b n/a - adzmax r u running stock injection may b thats why she splutters out of corners- if not think the surge is 4 u

I don't think the tank design on the GTT is to good. The GTR's have a small internal surge tank.
