Car bogs in the corners, road race.

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.

Btw thi happened with fuel bowls real low and full over the glass. Same symptoms...

Can you post a summit link to the race style float ?
What does that float actually do compared to stock ?

And jet extentions, I don´t see the reason for running them if not dragracing? As lateral g will make the fuel go to the side of the bowl, I don´t see how moving the pickup of the jets back and forth would help ? Not saying, just asking..

I can't at all agree with your conclusions. Here's why.

If you were simply "using up all the fuel on the straights" then even in the straights, at some point you'd lose fuel and the problem would start. I believe it is statistically so improbable that you would end up running the bowls out JUST at the time that you enter a turn (even when the straights are of different lengths) that it's frankly impossible for me to consider. Add in your initial comment about it happening when you "do donuts" and that IMHO totally disproves the theory that long straights are simply consuming your fuel.

If you're using stock lines (meaning probably 3/8 at BEST with multiple restrictions) and a stock pickup, and you're running a strong 502 at 600hp, you're in bad shape. That's way insufficient for that combo.

It's still just a guess, but with such a restrictive fuel system for that combo you could be starving the bowls all the time when you're on the motor. You can't see the sight glass when you're in the car and pushing it. Could be that when you're under load, no matter what the floats are set to the small line and weak pump/location can't supply enough fuel, causing low bowls, then causing starvation at lateral loads.

At that power level, I would replace your fuel line with 1/2"/-8AN, replace your sending unit with one from RobbMC which can handle -8AN, make sure you have dual 3/8" supply at a minimum to the carbs, install an Aeromotive 13205 deadhead regulator (if you don't have a regulator) and either put a RobbMC 1043 pump or a rear mounted better electric pump. For non-FI applications, I'm personally fond of RobbMC mechanical pumps, but that's a personal preference. Once you've done that you know that short of a sumped tank, your fuel delivery to the carb is rock solid and then it's just air bleeds, jets, and float adjustments.
