Possible fuel or electrical problem?

j&sracing · 8/6/12, 12:42 AM

We are looking for advice, help or a point in the right direction. The car runs like a scalded dog during hot laps but it starts fading in performance as the night goes on. When the car is rolling around the track, if I press down on the throttle it dies like I've hit the kill switch then goes back to an idle when I let off of the throttle. We are running a hilborn injection with down nozzles and a waterman fuel pump with a vortec distributor/built in coil and mag. Any help would would be greatly appreciated...on here, the message board or by phone.

Thanks for the help,
Shawn Miller

Tank vent, hi-speed bypass and or idle bypass leaking, barrel valve too lean? All cause similar pictures, how's it run under full throttle? Bob

If I can keep the RPMs about 4700 it will run like its just ben built below that it just falls on its face and slowy shuts off

Thanks for the help guys. It was a combination of leaking barrel valves and the pill. Not to point any fingers but it does help when the pill is placed back in the car.

Thanks again,
Shawn
