So now for Johns. 700 miles on the FTE now, 24-25psi, 3rd gear pull up to redline.

Also we ran it with and without the Gturbo chip, its got 20+% more power with the chip hooked up.

So the numbers are a bit lower than we had hoped. However what we got is around stock specs but not at the crank in a lab environment. We got it at all four wheels in a real world environment.

Now that we have some numbers I can also contact Gturbo, give them the numbers and have a chat about it.

What I can tell you all is real world driving, this Cruiser is impressive. Since we upped the boost, when you do a hard pull in 1st the front end if the Cruiser literally comes up an inch or two. I also chirped all four shifting into second on a real hard pull. Something I have never experienced in a full time 4wd 80, even v8 swaps. It also pulls big steep grades at highway speeds like a champ, 1/4 throttle at 70mph no probs with plenty of power to spare.

So there you go, the numbers. In my opinion the dyno doesn’t do it justice, the videos don’t do it justice and unless you have driven a FT/FTE 80 with 20+psi you really have no reference point or feel for how this Cruiser performs.

Cheers

This is a huge win, nothing more. Those numbers aren’t unimpressive by any stretch and drivability is truly the only thing that matters. This is such an impressive truck in every single regard.

The term “lifer truck” has never been more applicable.
 
Ian I think that’s great usable power and will provide a great long service life. I would be very happy with that!

The dyno runs all look in line with what I have seen. Most 1FZ’s I had on the dyno were between 125-130awhp and 180-185ft/lbs, so with the diesel you’re making 58% more hp and 80% more torque and getting better fuel mileage. I would call that a win!

No worries and thanks for your input. I was just hoping to see 250-300 and around 500ftlbs. It may be with a part time kit in it.

Like I say drivability is what matters, that and EGTs. Both are real good.

Cheers

That was my take away. We have same day comparison to a really strong 1FZ 80 series and the numbers are substantially higher. Time to change the oil and ship it back to Florida.

Agreed, these trucks really seem to suck up a lot of power. If you quoted engine power and torque the numbers would look huge. But really who cares about the numbers it’s how the truck feels when you’re driving it that matters. This truck will pull any hill at speed, go further in the back country and last a lot longer than just about anything out there. I wouldn’t let the pursuit of more power ruin a great thing. Just run it as it is. Just my $0.02 as I get older. Lol

My words exactly!!! As I said, it’s a work of art and probably drives like a dream.
 
Power looks to be in the right range for its purpose.

There are plenty of useless high horsepower car builds languishing in garages with zero real world functionality, not The case here.

Enjoy! If schedule permitted, I would have to drive that one back, the long way home.
 
Just trying to recall, did you guys have a stock fuel pump and injectors? If so I reckon you are about the correct numbers for where those components can take you fuel wise.

For comparison sakes, my HDJ79 made 240rwhp and 770rwnm. 2wd. That was on 33s. Same transmission ratios and gear ratios. Smaller gturbo but I ran out of fuel to go anymore.

Nonetheless, imho the best 80 on mud, and very probably the best 80 in the US. Congrats guys been an epic journey 🍻

You'll see close to that with 30 psi and fuel to match 🥳

At 25 psi and front driveshaft pulled, CDL locked I made 205 and 442 ft lbs, 1HDT with all the goodies and 4th gear pull, H151 transmission, so I'd say it's making about the expected power.

From my calculations, drivetrain loss on an 80 is around 40% which seems high but repeatibly accurate.

+30 on the injectors. It smoked a touch under hard shifts at 16psi, now, nothing at all.

@SNLC Do you know what the AFRs were during the run?
 
No, we don’t have an o2, currently.

Cheers
No worries, just would be interesting to know how she's keeping up with the fuel 😎

Also notice how balanced the power is compared to the 1FZ.

Torque and hp peaks within 300ish rpms. Not the case at all with the 1FZ. Obviously petrol vs diesel so not a very good comparison, in a big heavy 80 though the diesel is perfect.

I wonder if that has to do with the pull being in 3rd gear or the ramp rate of the dyno or something because we typically see max torque at approx. 1800 rpm and max power at 3400-3600 rpm, 4th gear pull, and have found ramp rate between 5-7 km/h per second is necessary for a diesel because we want it to load up and make boost asap.

I'm trying to find @Indestructible 47 dyno graph to confirm because it was the last FTE we ran.

For what it’s worth, I’ve consistently seen about 10-15% less on Mustang dynos than I have on others.

Chirping all four on second shift says it all!

Congrats guys. She’s a hell of a rig. Can’t wait to see it in person.

I was going to say the same thing. Every mustang dyno I've ever run me Evo on returned 10-15% lower numbers... and every shop that runs a mustang always calls their dyno the "heartbreaker dyno".

I’m going to have something like a local 80 series get together since you and everyone else I know around town drives an 80.
