To me wmhjr you seem to agree with my conclusions....
I said :
"My theory is that I´m using up fuel on the straights, in the turns the bowls are very low, causing fuel to slush away from the jet´s and therefore the bog appears to be in the turns, But in reality it is just low on fuel."
I should have clearified more. When on the motor I am using up fuel in the bowls. Not so much to do with the straights, only I´m on the motor more. This was happening in the straights too, it would run out of oooomph but first in turns the bogs started happening.
My fuel system w stock pickups, and that red pump that flows 20gph @ 7 psi is not supplying enough fuel. At 600hp I´m using 60gph (Very approx). It is clear to me the pump is not strong enough.
I´ve decided to run a black billett holley 12-125, the "new" billet one that is internally regulated, and run 8an lines to carb and debating on 3/8 (cheap) or 8an all the way to carb. It flows 140gph @ 7 psi.
As for pickup in the tank I probably have the smallest line, a 1/2" pickup would be best for sure. Might make a small sump in the rear with 8an instead of the $150 fuel sending unit.
If I´m reading you right we do agree on this ? The culprit beeing my fuel system is to small for what the engine needs.
Now the big question, how many gph is a holley 12-125 able to suck out of the tank with a 3/8 or 5/16 fuel line ? Not enough Is my guess...
Low on cash right know, so will probably do the pump and fuel lines first, and then if problem doesn´t go away, l´ll have to do the homemade sump.
