Anyone know if Ford/Multimatic disclosed the Fuel tank size? 100 or 120liters?

I am hoping for a larger tank than the GT500. At the Daytona Speedway, running a 5.2 L supercharged engine (with the foot on the floor) fuel starvation symptoms begin in about 16 minutes. I expect fuel flow to be similar to that of the GT500 and it will require a larger tank or a tank with some means of using all the fuel without starvation. Part of the problem (I believe) is the saddle in the tank to accommodate the driveshaft.

The 5.2 supercharged engine is very thirsty.......

I figured I should probably change the e-mail responses so they aren't coming from my G-mail. :LOL: Had to test it out.

Confirmed this morning it's the same 16.0 gallon fuel tank as the regular S650.

Unless they figured out a way to utilize everything down to the last gallon in that tank under WOT, that's going to be a problem. I can post a video of me at Daytona where I began sucking fumes so to speak at 16 mins

Edit to add:
At 16:14 you hear a loud hiss followed by a loss of power. This problem plagued me all the way through the rest of the session. This is not a one time problem. It is a common occurance. And yes, the tank was full starting out.

I belive there were some guys in the 350 section over at M6G that figured out a better crossfeed system for the fuel tank that alleviated a similar problem. I hope the folks at Ford and Multimatic have this one covered.

Generally hate modifying stuff, especially this car, but catch cans work as a practical matter. Finding a tasteful solution might be tough.

As you my know, not a good idea to fuel starve with a boosted engine.

What's a liter?:p

On a serious note, are they running a fuel cell in the GTD?

I would expect not, as there is more inspection and maintenance needed for the foam and bladder of a fuel cell.

Stated above, by DBK, confirmed, same tank as GT500.

If you read the above thread, it’s the 16gal normal Mustang fuel tank that’s in question.

Right a fuel cell would be way better from a pick-up and capacity standpoint.

Ok the size is confirmed but the follow up question is dual pickups or some trick cross connect to extract all the fuel without starvation. Basically run 30min on any Track in USA.

How much fuel is left in the 16-gallon tank after 16mins of running?

I can't say exactly, but less than half and more than a quarter. The Audi Club Daytona was cancelled this October, so I probably won't get to run unrestricted like that until the next Audi Club event. Other clubs that run Daytona don't have an unrestricted class and have point bys and slower, more restricted environment (which does increase endurance).

There was a similar issue with the GT350 where people were complaining that they always had to start with a full tank, because once they got below half a tank, they would have similar issues. The solution that they came up with was to add a second fuel pump for the drivers side saddle of the fuel tank. There might have been a better crossfeed system set up, I don't recall. However, running a forced induction car under very high fuel flow circumstances will lead to the same problem unless they engineer around the problem.

I found the article. The solution begins on page 4, and is wrapped up by page 5. You can see from the video, after the 16 min mark, there was no more foot on the floor driving. Anyway, the link......

T,
Thanks for the link, great background and info. I’m going to be with a member of FP next few days, will get their thoughts. If public will share but as you know sensitive to items not released by MM/F or deemed secret.

Again, I’m sure they’re aware and will address it.

A fuel pressure gauge on the digital screen and manual switch (labeled, reserve tank) at minimum.

IMHO, the 16 gal tank is about as small as it gets in any Track focused car, you better be able to use all of it or real close to all.
