Fuel Surge

[grepin]

Anyone had any problems with fuel surge after fitting a Bosch 044 to a R33. Happend about half a tank under track conditions. On the track is the only place I have really had a problem.

Cheers.

what exactly is fuel surge? what does the car do? and are you sure its fuel surge? what other mods have you done?

Racing around the track with a full tank no worries. Got down to about a half a tank and when hitting hairpin corners hard motor splutters for a moment and picks up again. Acceleration in a straight line no worries. Mods include standard peripherals including fuel cut defender. Tried turning boost right down still surged.

If it only happens when you are taking hairpins on half a tank, then by fuel surge, you mean it all sloshes to one side of the tank when you take hard corners?

and it still does it at low boost, which should eliminate the fuel cut defender as the problem...

does sound strange. is it possible for the pump pickup to become exposed to air if you dont have a surge tank? (ive never seen inside a tank) Coz thats what it sounds like, only happening when you corner...

Ive just had fitted an 044 myself, but have yet to take it for some punishing corner work. But with my old pump, i used to rip around the hills on empty and never had any probs

hope you get it sorted, any big tuning house should be able to tell you why its doing it.

hey, an adelaide boy. Me too. Go to RPM Performance centre or Tilbrook's. They'll sort you out for sure.

whats your car look like? maybe ive seen it around?

I can't figure out how the pump would affect fuel surge one way or the other. If you're getting it, just buy/install a surge tank. Simple solution
