Default Coping with fuel starvation

While running at Atlanta Motorsports Park this weekend I ran into the fuel starve issue, long and fast left hander followed by a fast right. As soon as the car transitions to the right, fuel cuts for a good 3-4 seconds. After the fuel settles, power gets back to normal.

During the fuel starve I kept the gas pedal down until power came back. From reading a bit more into it it sounds like this could be dangerous for the engine and a risk of blowing things up for running lean.

I'm not ready to install a surge tank yet, so what is the best way to handle the situation and prevent damage, aside from slowing down ? Would letting off the gas and press the clutch in to lower the revs help? The right hander is followed by a longish straight so I'm not worried about upsetting the car more than it already is...

Thanks!

you could try bringing gas with you so you always start the session full of gas

Agreed.

Unless this happened w/ a full tank which I doubt.

Happens when 3/4 tank or lower. I don't mind filling up after every session, but I was wondering what is the safe way of handling the event when it happens.

well abruptly lifting mid-corner isn't safe for you or the car, so just remember to be smooth if you do decide to lift.

another solution might be that hydro-mat thing holley made that replaces the fuel sock

Lifting won't upset anything as the fuel is already cut

Does the ECU know if there is actual fuel in the cylinders if the gas pedal is pressed but the pump is pushing in air? Disengaging the clutch and bringing the RPMs down quickly would help prevent damage I suppose but that might actually upset the car

Do you have an aftermarket fuel pump?
