So ZFG Racing, what's next for the go fast?

[Combatvet]

I got walked down by a new Shelby F150, so I need to be a bit faster.

What's the next go fast upgrade for my '25 ST. Already have the usual bolts on's. DP, Exhaust, Intercooler, tune.

I need Mo Powa!

Depends on your tune. If you want to go partially or full ethanol (if you haven't already). Next comes upgraded fuel system/injectors, and then upgraded turbos. There may be some details in between, but that's the gist of it.

Well... I would tell you to not feel too bad. He may have close to 780 HP in that truck.

True. I don't think weighing 600# or so less is even enough to compensate for that.

 

[SugarMouth]

Bit faster? E50+. Faster more efficiently? Turbos.

 

[Gadgtfreek]

I wouldn't sweat that, honestly. Tuned 3.5 F150's are fast, and that is a whole other machine lol. Might as well throw built 10R transmission too.

 

[UNBROKEN]

My 2016 F150 would have beat probably every ST on the planet.
A stock Shelby truck is pretty easy for an E50 tune. 775 is at the crank on those so rwhp plus the added weight makes it a fun fight. Once they start modding they make more power very easy…not much you can do after that.

A full bolt-on Explorer can easily run in the 500–550 whp range, depending on the dyno.

The number one limitation is the fuel system, which can barely support an ethanol blend between E30 and E40 (I still don’t know why they call it E50). If you want higher ethanol content, you need to upgrade the fuel pump and injectors. On the F-150 platform, the engines are both DI and PI, so they can make about a quarter of that cost just by improving the fuel system, while on this platform you have to budget close to $5,000.

The other two limitations are the transmission, which is rated at around 600 lb-ft of torque and is already at its limit, and the turbos.

Anyone aiming for 600 whp should expect to spend around $10,000, just to put a number on it.

Shelby Trucks are blown 5.0's not the 3.5.

If it was a regular cab , those are 10sec trucks and from the move they are deadly with the 10spd.

These cars have no issues with E50.

I understand that, thanks.

The point was, the 3.5 tuned is already fast, and then I noted the Shelby was a whole nother animal. I looked hard at the lowered and whippled F150's before the ST, decided to spend the $60k on more room.

A simple tuned F150 with a 3.5 is damn near as fast as a tuned ST. And Ive seen numbers where they are faster.

many people maxxed out injector in E35 blend u can running E50 but less power in stock injectors

I guarantee most are making more power on E50 than E30 or 35. There’s countless dyno sheets out there to substantiate that and even the most uncalibrated butt dyno can feel the difference. My own car is 2-3/10’s quicker.

So, if I made 557 on E35~E32, are you telling me that I still have room to make more power, even though I ran most faster than expected? An 11.48 full weight?

Yep, with the factory fuel system @E50 it will be figuring out which is more beneficial, boost or timing. Sounds like timing from what you are saying.

I think key work is most. Peter for example, before upgrading his fuel system obviously, was running around E40 because fuel system were maxed out. Obviously he was a lot faster than others, but some find better results closer to E35-E40.

I would be curious. Different platforms respond differently. I have very limited experience with ours. Some take 90% advantage of E at 50-60 in terms of timing advance. If you are E32, I would be curious if less boost at E50 would be beneficial.

For vehicles I have played with in the past, I found if I could run the turbo within efficiency range at E30 I got good results.

E35... Peter (Maxed Out)

Im curious how you're "only" running E32 on an E50 tune and seeing big results. ZFG's 93 Octane Tune is good for up to E30, so it perplexes me a bit. Those numbers also seem pretty high if your mod list in the signature is accurate.
