Stuttering at Spa?

[cantfind1]

Question for all of you that have done Spa.

Coming out of Stavelot and running along Courbe Paul Frere towards blanchimont in 4th gear foot flat to the floor the car is stuttering, change into 5th foot flat to floor and it will then hesitate again.

Only doing it on this particular stretch?

I was thinking fuel starvation but with just under half a tank i was still getting it to occur occasionally.

Any thoughts?? anyone else experienced this?

I got that in exactly that place, assume was fuel starvation, with me went away if I filled up.

had it once there (but only when car was older)

also at Sears (Snetterton) and Coppice (Donny) but once again only when car was over 50k miles :smokin:

My lovely motor car only has 41k on it now :-)

Ah good to know, well not good, but at least its a common fault.

I have already replaced my fuel pump, filter and pressure regulator, so I think it s time to look for some sort of upgraded pump.

Seems the OEM one, even when new, is not up to the job, must be something to do with long sweeping turns?

Cantfind1 - consider using the oem as a riser to a litre swirl pot then a proper pump from there.

You clocking it then shim :whistle:

Yeah have thought about the swirl pot idea, any clues as to where to find out about this setup? Or who can do it?

Any race shop mate, Simpsons, steels, intersport, thorny etc etc. I would use Simpsons personally but a lot depends on geography.

Cheers Nathan, will talk to simpsons they owe me a favour!

[northernjim]

could it not just be the fuel pick up line in the tank having been dislodged??

might be worth looking at before buying a pot and extra pump:beer:

I had it when down to just over 1/4 tank, only seemed to get it coming out of sharp corner with slight incline.

Tried to leave half tank minimum and had no issues.

If others are suffering I reckon its poor baffle design.

no stuttering, and no remap.:thumbs:

Have found my solution!! Well CA found it.

I already have a spare pump so the cost for me will be reduced quite a bit.

But this is a pretty good solution to a problem that most of us have. And its OEM!!
