What problem were the DH cars having that your pump/pump+module fixed?

 

[KPM Fuel Systems]

The DH was experiencing starvation/ surging issues on high speed cornering when less than 3/4 of fuel in the tank.
The KPM fuel module completely rectified this issue eliminating starvation/surge at any fuel level down to an empty fuel tank.

These are pretty bold claims to make, considering you assume absolutely no liability for damage as a result of using your product.

Im kind of curious as I didnt know this to be an issue on the Dark Horse today?

Ive seen a ton of track videos and not once have I ever seen someone run into this issue.....I would think the Dark Horse owners would be up in arms if this was happening- dont see any threads on it here as well?

The fuel surge issue was mentioned here, in Misha's video:

Start at 14:54

It’s shocking how many people don’t know this has been an issue on every s550 and s650 besides the gt500 that had dual pumps. Besides the weight it’s the biggest complaint to have with mustangs.

It's an issue.

So how does this help with the issue?

I thought the fuel starvation occurred because of the shape of the tank, and the fuel pump being on only one side?

Here is the shape of the S650 fuel tank (sorry if that was your totaled car). As you can see, there is a steep "hump" in the middle. In high G force corners, the fuel when, say, half full, may end up all on one side of the tank, away from the pump.

Now, I know some solutions use two fuel pumps, but this looks like just one high volume pump supporting up to 800 horsepower?

What am I missing that makes this deliver fuel when coming out of a 1.2 G sustained turn and then getting gently up to full throttle again, but all the fuel is over on the side where the new KPM 800HP fuel pump is not?

This looks like a relatively inexpensive solution, but I would like to know how/why it works?

So there is some sort of line running from the non-fuel pump side to the fuel pump side.

KPM advertises a full "canister" at all times. Maybe that is enough fuel to keep the engine from starving during sustained high G force turns? Or maybe they improved the suction to pull fuel to the point that it keeps up with the exiting of fuel through the pump and out to the engine? The second part seems highly unlikely, but I would love to hear more about it, how it works, basics, what they changed, and the result, what it will and won't do. Maybe it simply increased the amount of fuel in the canister to the extent that on most race tracks this is no longer an issue?

If anybody knows, please chime in.

I took a DarkHorse driving class at Ford Performance in Charlotte. We didn't have any issues, but maybe they already had it sorted out.

I think they keep the fuel tanks close to full.

This type of fuel pump I believe actually holds some fuel in there "at the ready" like a holding tank. Anytime fuel passes by, it fills the holding tank. The fuel is actually pumped from the holding tank.

The 2013 Camaro SS 1LE I owned had a fuel system with multiple pickups in the tank to eliminate this issue, can't believe Ford has gone this long with this problem. Should be mandated they replace the fuel pumps under a TSB with this setup.

 

[Junkyard Dog]

I think they keep the fuel tanks close to full.

When you do an HPDE track day, though, you will burn through more than two tanks of gasoline for the day, so it is really difficult to keep it "full."
