yeah that is what i thought that one turbo spins up first and then the second spins up some time after it, idk if all twin turbos are designed that way but i know some are, a smaller and bigger one.

Inline 6 is big bore all stroke. More tq m8

Inline 6s are beast at towing.

That's why Ram uses Cummins inline 6 turbo engines in their HD trucks

I'll stick to my V8 TRX. : )

What’s the point they barely get better mileage than a v8 and won’t last as long

HA! I woke up to my typo. Smartass Miscers.

Yeah but they're half a Ferrari. A v8 is just 2 chitty honda civics stuck together.

What does a Ferrari have to do with a Ram truck conversation?

It requires the same amount of air and fuel to produce that 500hp regardless of cylinder count

The difference is the smaller displacement will be under a ton more stress doing it, meaning far less efficient & more prone to failure
Anything under boost is a ticking time-bomb

All of these small engine turbo designs are breaking fresh off the showroom floor


Imagine trying to move around a 7,000lbs truck with a 4cyl; autism















We literally had better fuel economy in the 90's than we do today due to the ever tightening EPA restrictions

These 500hp I6s are just an exotic v12 cut in half. They are using all the same tech to make that power. These big conglomerates share technology and manufacturing space.

Turbos are for 2 things.......throwing as much boost down the throat of the strongest V8 you can afford to make it the fastest it can be before bending a rod or lifting a head AND Big Diesels so they can have the torque to pull a house off it's foundation.

and nothing in between.

We hit vehicle singularity about a decade ago.

Nothing new actually matters.

A lot like cell phones.

Oh this one has a blah blah engine so that...erhm...so that....you use it especially to...uh....go places.

You go places with it.

Similar to your 95 Honda accord, you go places in it.

Oh and it can carry a payload of blah blah and go so fast with it....but, uh, we all know you're gonna use it to bring foliage to the dump and move a couch.

2jz will decimate all

Ahhh. Ok. I see what you were saying.

ROFL Sure it does. Maybe if you only count freeway miles. Once you add in all of the idling at stop lights and stop signs it's more like 8MPG. And that doesn't even count the supercharger.

Love the engine but hate having to buy high-octane

Do you have to? I thought a lot of newer engines would stay in tune with different octane ratings. Just won't give full power on lower octane.

The Ford solution is called an Octane Adjust Ratio (OAR) and the strategy controls access to three distinct load (think boost) limiting tables which we can for the sake of discussion call Low (93), medium (95) and high (97) octane tables. and an infinitely variable ignition system that reacts directly to the inferred octane and runs advance appropriate to the load table it is running in.

So, under very strictly controlled conditions the system will try to increase spark advance itself (Yes - This engine self tunes) in order to improve engine efficiency to the maximum your fuel will allow. More advance effectively reduces heat, improves fuel economy and lowers emissions, these are the O.E's main goals. As luck would have it for us enthusiasts, this also improves power.

As long as the engine responds positively to the advance added, with no knock, the strategy has proven that it currently has decent octane fuel and it moves towards its higher octane tables, unlocking both additional advance and additional cylinder load as a base. It then runs this new higher base setting and repeats the self tuning process periodically when certain criteria are met and it does so until such time as it has advanced to its full load and ignition tables 100%.
If the engine knocks badly at any time, it will move the other way, towards its low octane tables, thus lowering load and ignition advance allowance. It’s position between these blending tables is indicated by the OAR Figure which will be somewhere between a best of -1.00 (High-97) and a worst of +1.00 (Low-93) A middle position is an OAR of 0.00 (95)

You guys are retarded.

It’s Y6. Pistons come down in the shape of a Y. Next level engineering.

In b4 it's in the shop every other month

Has anyone asked why we need 500-600hp in a half ton?

We bitch an moan about the bloat in price but keep stuffing screens and bigger engines in, it's way past what anyone needs a typical half ton truck for. Why cant we get an overbuilt 300 horse engine, focus on mileage and reliability instead of headline horsepower numbers.Every commercially produced million mile truck engine in use.

So gen Z can tow their tiny home around.

91 is required if you want to see those performance numbers and fuel mileage especially in the hot summer months. I'm familiar with the concept of variable timing but I'd never run 87 in a FI engine. It will run like hell.

These TT6's STOMP normally aspirated V8's in torque. Just look at the torque curves of any of these modern FI engines. 90% peak torque (425'ish foot pounds) comes on at 2300RPM, and peak 475 foot pounds at 2850 - 6000RPM. Where as the 5.7L is only 410 foot pounds from 4000-4400RPM.This motor has an individual turbo per 3 cylinders, Ford Ecoboost V-6's are the same way. They are parallel turbos, not sequential turbos like you are thinking.Even the Standard Output 3.0 whoops the old 5.7L, let alone the 3.0HO. In the Grand Wagoneers, the 3.0 HO Hurrican motor TROUNCES to the older SRT 6.4 powered Grand Wagoneers.

And before you try hard V8 guys get your panties in a wad, I have put over 110K miles on my 2014 and 2020 6.4L Jeep SRT's over the last 9 years, and have almost 80K miles on my 2020 Ram work truck.

This new Hurricane motor is legit, and should be REALLY nice once they utilize it with a hybrid system.

No thanks, I will strap a turbo to my own inline 6 incher and watch me fly.

POS that will have transmission problems by 50K miles like most Dodges

Except they use ZF transmissions not their own pieces of crap they use to use

A mild hybrid just has an electric motor to provide power for a split second when the engine start/stop at idle kicks in.
