PM me if you want details on my fuel system and how to solve this. Surge tank isn't the solution.

If surge tank isn't the solution, it would be really helpful to be shared with the community as that is the only viable solution I (and many others) are aware of.

Yes, however, I don't have time to do a full write up at the moment, so I would prefer to discuss it in private to avoid any group confusion. The experience and education level on forums vary so much, I don't want to be responsible for someone making a mistake while trying to do a massive fuel system conversion without a proper write-up.

Fair enough. I should have said the surge tank is the only plug and play type solution I am aware of. Certainly massive changes can be made.

So has anyone thought about installing some sort of drop in baffle balls?

Essentially plastic whiffle balls that would not displace much volume but would get jammed up in the middle of the saddle during high g corners and essentially create a barrier to the fuel sloshing to the other side.

It seems like this is used in other applications successfully. Also it would be fairly simple to do as you would just open the fuel tank and drop them in rather than a complicated surge system/fuel cell and there's no risk of deterioration over time like there is with foam.

Something like this but the size of ping pong balls:

or this in the golf ball or baseball size

Edit:

So apparently wiffle ball plastic will dissolve in gasoline over time, but the tank itself is made of high density polyethylene (hdpe) so I figure it must be safe to use HDPE baffling. My idea is to get some quality HDPE hollow balls and drill some holes in them. Any thoughts?

Edit 2:

I found a patent filed by Goodyear in 1965 for this exact idea. https://www.google.com/patents/US3349953

We install a lift pump in place of the siphon tube in the passenger side tank which helps a ton. Eventually even that wouldn't cure it but our car pulls 2G so it may work for most people.

What happens on the boosted car is that the bigger fuel pump or higher fuel demands can empty the oem surge faster than it can recover. It doesn't recover fast enough on the track due to fuel sloshing so your siphon system isn't working 100% of the time.

It is hard to say but you need to go to Auto Machnique. So, He can identify the problem and solve it.
