I just picked up a blown alky motor and am questioning the fuel system.
I have made 2 partial passes in the car and it was either running out of fuel or hitting the rev limiter, scaring me, and lifting. Wish I knew which but never looked at the tach and it does not have a recal. The motor is pig fat and all the plugs have had none of the cad melted, so I am hoping I just was hitting the rev limiter, but now I am also questioning the fuel system.
First the pump is a hilborn PG-150B that I know nothing about other than when you look at the hex input shaft it is slightly twisted. Trash or fix and flow?
Second it has a short #10AN line from the tank to the pump and out of the fuel shut off valve is a 6AN adapted to 8AN with 8AN lines to the enderle cube. From what I read I am guessing I need a bigger line from the tank to pump... what about from the 3 way valve to the cube?
Based on this web site and running the tune up calc it looks like the motor needs approx 4 GPM at 8000 rpm. http://www.fuelinjectionenterprises.com/
The motor is a 400 cid, 12 or 13:1, running around 10-12 lbs of boost.
