I was here when we had to replace parts while the car was on the dyno. The hard piping system is also supposed to be on your list of parts to change for next season. That is because they do not allow the entire system to flex. At that power level there is a ton of excess stress on the OEM rubber parts when there is a harder material present leveraging its transferred kinetic energy. Thus, the reason that you want to avoid adding hard pipes for a build of that caliber.
Ford is NOT using anything anywhere near this setup at all whatsoever on the new GT. As per usual we cannot share our insider information, BUT if you happened to read the thread a few weeks ago where someone brought up this topic I made sure to emphasize the fact that the GT is going to utilize a completely different set of "system
S". The emphasis that I placed went completely unnoticed.
Adding something like a
standalone fueling system like a megasquirt for example is not practical for a street car. That is what the OP is talking about! Stay on track. There is not a way for a STREET CAR to upgrade its fuel system. There is no way to add an in tank upgraded fuel pump like you can on a Gen 5+ Camaro. There is no in line solution like there is for a C7 Corvette. There is no bolt on pump that you can add like on the Raptor trucks, and even in this example we are the ONLY solution for this modification. Changing out the LPFP is going to do ZERO for you. Changing out the HPFP is going to do ZERO for you as well, because the real issue is that there is a metering system that bases the car's fueling output from how quickly it can measure the revolutions of the last lobe of the camshaft. This "meter" is an internal component that cannot be modified to allow for faster readings. There is for lack of a better word a plunger that rests on that lobe of the cam, and the HPFP delivers fueling based upon its movement. There is no way to increase the "plunger" travel either.
@White Beast, sweet looking pump...it really is.
We have already explored that option, and the same goes for "better" injectors. We have looked into larger fuel rails too. The problem with respect to like a larger rail is that if you deplete the supply in the rail you have now starved the engine and are asking for turrible things to occur. Is that worth it for a street car, of course not.
That is the thing to remember here guys, the OP is asking about his 4400lb family sedan. It is not a grand touring car.
They are not equal.
Don't get me wrong, is it amazing that we can exponentially magnify the capabilities of this COMPLETELY unassuming family hauler? ABSOLUTELY!
For what it is the platform is on another universe! To think that a little 3.5L transverse turbo car can run with its Euro sport sedan competitors is amazing. Nobody can argue that!
