Today at an autocross meet the car was doing great. EXCEPT that after a sharp curve there was a delay in getting power, with he engine running lean. We were running a half tank or less to save on weight and it was suggested that the problem was fuel starvation after a sharp turn.
Having looked inside the tank it don't seem so awfully likely, but it does fit the symptoms. Driving back on country roads I went across several 90 degree bends, and the same durn thing happened! (IMG:style_emoticons/default/hissyfit.gif) Any thoughts?

ok, so is that a fuel accumulator?? where do you put it? Upstream or downstream from the existing fuel pump? It works with fuel injected set ups, yah?

A fuel accumulator is a small tank (1 quart or more) fed by a low pressure pump drawing from the tank, with a return line that goes back to the tank.
The return fitting is at the top of the tank so it stays filled at all times.

The primary fuel injection system draws fuel from the bottom of the accumulator and returns the excess back to the accumulator.

That way the high pressure FI system never sucks air unless the fuel tank is totally empty.

It is well worth the investment if you're chasing trophies. (IMG:style_emoticons/default/first.gif)
