scofffers may scoff all they like but the man putting big horsepower to the wheels with his turbocharge 8 in Puerto Rico is doing so after modifying his fuel system with a better pump and a return line. just FYI

There have been reported cases of fuel starvation on the track when the tank was less than half full.

They do suffer fuel starvation around the tight race tracks. I found at Winton if I had any less than 1/2 tank it would hesitate around tight corners.

I dont think this can be blamed on a returnless fuel system though. More to do with the baffling in the tank.

Not because it is starvation. It is to protect your vehicle.

Besides fuel in fuel tank, we have what? Yes air!

If the fuel tank is half empty. The G force of the car under corner may put some air into fuel lines and just may be it will have some advert effect> it just bugger the fuel injectors and stuff. I am not sure the detail but it is common practice - may be it is a myth. But I read somewhere in Jap magazine recently - they still tell us to do it in recent models.

So long as you haven't got to the keg yet, don't worry about it.

Mind you, I have to laugh at the fact that guys carrying 20 excess kgs always seem to be the ones buying up the carbon fibre bits for their 'rides'. :p :D

No myth, I experienced this on track at Watkins Glen, last run, didn't bother to refuel and was at 1/4 tank. With approx 1G load on right-handers caused this annoying behavior. Seemed to happen on long sweepers more than tight turns...so like 1/2 way through a 1/2 mile bent-to-the-right straight run @100+ it would occur consistently as well as selected tight turns. I think it normally takes a certain length of time to starve enough fuel to cut the engine.

No urban (track) legend this!

That sounds like potential results of fuel starvation to me :p

Be nice, occupational hazard, worked for a brewery for 11 years...and I like carbon...preferably the black bits on bbq chicken.:p

Oh and on Loc'sk question, for us mortals for whom fuel starvation is likely to be due to a hurricane induced oil shortage rather than high speed...sorry you lost me.

It's the sway bars i reckon, not a serious performance defect but can do better.

An the fact the bloody windows don't roll up after the passenger opens the door!:D
