Need some advice

[COYOTTMach1]

Hey guys new to the coyote platform. Been into the LT1s and LS1s for quite some time. I sold my 427 22 na maro 10 speed and came across a killer deal.

I found a 2021 Mach 1 manual with 9k on it 4k on the build. Its a gen 3 i have all reciepts on it as well. The previous owner put in boundary oil pump gears and crank pulley. Has a Hellion sleeper twin turbo system, 4 into 1 header option, 62/60 turbos. It has the 1050x injectors and w400 fuel pump in it. Resonator delete and digipower dual 3in cutouts as well. It was tuned by Lund using hp tuners and made 764 whp on pump and with 50:50 pump and vp 110 made 945 whp. The car with closed cutouts made 854 with them open gained 90whp where it got 945 whp.

The car is my daily driver and i am very happy with it thus far. But i want to know if im pushing it to hard? I drive pretty calm on the streets with some spirited driving just on low boost 5.5-6psi. To be honest ive not even tried high boost yet which is set at 12.5psi. The car is used for daily driver and some fun here an there with a few roll race days at the local track using a weld s77 drag pak. Was wondering if i should look at getting a better tune by someone like palm beach or wengerd? Seen a few articles where palm beach has been able to get over a 1000hp on pump gas on a stock sealed gen 3 same turbo system with some fore fuel system upgrades. Been looking into a fore system as well. Sadly i would love to have a flex fuel sysyem like my gm had but was told ford doesnt have this yet. There is just one E85 station here so dont want to be limited to having to fill at that one station. To bad there isnt a on the fly tune switch to go to 91 to e85. Maybe in the future.

Would just love to get some suggestions even if its your good leave it alone haha. Thanks guys excited to be a part of the coyote group so far very impressed!

You have a few options for flex fuel…..but they generally involve self-tuning using pcmtec. I’m running stock-style flex-fuel on both of my personal vehicles using ford’s oem logic.

That sounds like a killer ride you have there! I sure do wish I was making that kinda power.

You mentioned doing some drag strip roll runs. Any chance you can see what it does from a dig at the strip next time you‘re there? I’d love to hear how it sixty-foots and what it does in the 1/4.

First, if you watch the PBD video some VERY VERY important caveats.

1) The car that made over 1000 rwhp on pump gas was a 9.5:1 compression car. So unless you're planning on an engine rebuild, there's that.

2) Ken fully admits in the video that "is it safe?" Doing 1000 rwhp on pump gas sitting in dyno conditions is different than out and about on the street. He even goes on to admit that while they've done some 900 rwhp GT500's, he kinda implies that leaving it at 1000+ rwhp on pump gas is a ??????

If these forums have taught us anything, it's trying to find the edge of performance on pump gasoline usually ends in carnage.

As far as flex tuning, several tuners now offer PCM tech and "user selected" flex tune (meaning a workaround where you select the tune profile that matches the fuel alch%). Pretty close to true flex fuel.

It's questionable the car made 945 rwhp on just 12.5 lbs of boost. It's not TOTALLY out of bounds absurd like some of the early ESS thread claims, but it's more likely the car was making more boost than that to reach 945 rwhp.

Assuming the car makes something around 440-450 to the wheels in it's current flow components N/A, that would mean that theoretically, you'd need well over 100% adiabatic efficiency to make 945 to the wheels on just 12.5 psi. Not a huge deal, just FYI. Not questioning the 945, but typically we see higher boost levels to make that power (even with turbos).

For the last part of your post, reliability comes down to how the mechanical arrangement of the car is setup and the tune, but also in how you use/abuse it.

A car that sees redline sparringly and only full WOT rips at nice cool conditions will live a lot longer on the ragged edge than one that's ripped back to back to back heat soaked, or ripped for 1/2 mile extended runs or dogged in high gear at low rpm with 3 friends in the car uphill on sticky tires. How you beat on it gets a vote.

If you want to abuse your car or have it give you everything it's got, anytime, anywhere in any conditions, I recommend NOT having it live on the edge. Conversely, if you want it on the very edge of what it can do, I'd avoid back to back to back hits and I'd pay very close attention to IAT temps and I wouldn't try to do pulls with the chassis loaded, etc.

There are a few tuners using PCMtec. They have a can-bus flex system that uses a sensor to give real time E% and computer tuning, like the GM system. I really don't like Lund but I know they use PCMtec software. I think Wengerd also uses this system.

Thanks all that took the time to respond so quickly i appreciate it. As for lund i messaged and he said that there isnt any flex options. So theres that i did message Wengerd and he feels theres more in it. I do not take it wot often let alone into boost to much. I do an occassional 1st through 3rd pull and its fun. As for the roll races its only 40mph start point and its 1/8 mile. We dont have much in the way of good tracks here they got rid of the one drag strip we had.

I have IATs as one of my main readings as well as cylinder head and afr. As for the 945whp heres the dyno graph with the cutouts closed and open. Also here the low boost as well. It was on a dynojet thats known to be pretty accurate but whoever knows.

 

[COYOTTMach1]

Some reason the graphs are loading, i can send them to someone if that helps dont know why the others loaded fine.

I didnt see anywhere in the article that this was a 9.5 built motor says low mile gen 3 that they changed the oil pump and crank sprocket. Maybe i missed it https://frontstreet.media/2020/04/1...makes-1047-rear-wheel-horsepower-on-pump-gas/

But really thinking of letting Wengerd do the tune i dont know much bout coyote tuners. I heard lund is really good but when i started looking around i saw Wengerd was the one most recommended.

 

[Angrey]

Thought you were referring to this car:



If they made 1047 on pump gas with no change in compression and without some other safety mitigation (like an ass load of meth injection) then it's a ticking time bomb.

In the video you hear Ken say, he's comfortable sending the car out the door at 900-950 (on reduced compression) but over a 1000 is probably just begging for detonation in the real world.

But I'll defer to John Urist and his expertise over mine.

Sweet ride, great looking car. Just my very humble opinion, this is your daily and if it is your only vehicle to get you back and forth to work or whatever you do to make a living, I'd be very cautious with this set up. A lot of power has been engineered into your car, but long term reliability engineering has taken a hit. As others have stated, lots of boost, high compression, and pump gas = big bills. The other thing to consider is what if you get a bad tank of gas.

 

[COYOTTMach1]

Oh i agree with you all im not looking for big power over a 1000 right now. That will come later after i save up get the aluminator 9.5 and then maybe ill turn it up an try to get more. I am more asking if you think its ok the way Lund has it running. They spent several hours on the dyno tuning it. It does feel great maybe just let sleeping dogs lie and enjoy it the way it is. Powerwise im very pleased i mean like i said havent even tried it on 50:50 mix of pump an vp110 and the 12psi boost.

 

[HKusp]

If you're not adverse to letting Wengerd look at it and tell you what he thinks, do it. He's a straight shooter.

 

[mejohn50]

OP, here's a good breakdown of what PCMTEC brings to the table for flex fuel.

Bottom line: it *can* be done like on GM, you just need a sensor and CAN-bus adapter programmed and installed correctly, and you need a tuner willing to tune it.

I would talk to a few different tuners and see if any of them offer what you are looking for. I am sure you will find someone that can do what you want to do with flex fuel.

If you’re happy power wise, it’s running good, and you haven’t even put it in high boost, I’m not sure why you’re considering a change. Sounds like an awesome ride, just enjoy it!

 

[GL95]

Flex fuel is possible, not sure why anyone told you it wasn't.

 

[COYOTTMach1]

Would really like flex fuel if i can get that figured out at least i could use E85 from time to time as well.
