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? |

I would start with a new higher volume FI pump. A fuel accumulator requires a tank and a secondary fuel pump. There should be no need for an accumulator at your HP level. You should also replace the pressure regulator.
Also make sure your supply and return in the tank are not reversed. Do you have this problem with a full tank? BTW, I'm running a single pump in the front and a +300hp turbo motor and don't have this issue. |
