MITSASH*TTY TRITON 2.4MIVEC Can it pack a punch👊🏼 Modifieds signature package gives these small cube motors hope 🫡 surprisingly these come up exceptional, either reliable gains they actually produce some very healthy gains in power & torque 💪🏼💻📈

N70 1KD HILUX 3inch exhaust only mod 🧐 what’s efficiently available power & torque wise and what sort of gains to expect 💻📈 PLENTY 🫡

200series PRO SERIES PACKAGE 🫡 All the Y62 patrol owners hate this package. Double to torque of your inferior petrol 5.6ltr V8, more than double the fuel range after this package too 👋🏻 nothing like some Friday bants, nothing like stirring a Y62 owner up. They be jumping in here defending them selves while filling up for the 4th time this week 🥲 Toyota. Enough said.

2WD RC COLORADO 4JJ1 RIPS 330hp / 700nm once we dialled in the Staunch little build 💻📈 Asking for a hard cut to be HARD Pops and Bangs 🍆

This is the limit of the the stock HP3 but the better thing about these, the high pressure pump setups to that compared to the 1KDs is that they are setup with a 1:1 Ratio with the motor. Able to deliver more efficient rail pressure earlier in the rev range than a 1kd setup really helps these make more power BUT we are still at the limit of this stock pump. A lift pump has been pre installed which is the minimum requirement once running a +30 or any high flow injector 🫡

Tapped out at peak 1500usec on injection open time. This was the limit of rail pressure also as anymore on time seen a dip in rail pressure logs not meeting target.

For this little setup it’s beyond impressive on the street, with 3rd roll ons not being a problem to break traction. Great sleeper build. That will shock plenty cars on the street to be walked by a diesel let alone a P plater 😳

ZD30CRD HAS THE PIN BEEN PULLED 💥🤯 let’s dive into what can truely be achieved, what weak points they have. MOST of all where’s the LIMIT 🫡

1KD N70 HILUX out of high pressure fuel pump 289hp / 657nm 🫡 With a large set of injectors the next limiting factor on your 1KD is the HP3 fuel pump if your wanting over that +300hp / +700nm, not only is it just about rail pressure. It’s what comes with a high pressure fuel and understanding what rail pressure does to a built high flow injector 📈

With a large high flow injector we want to shorten that open time (on time), with that we want rail pressure to back it. With low rail pressure or a pump that can’t supply enough rail pressure at certain RPM’s your limited on the MG/S 💻 what this means is at 1800bar we maybe able to deliver 180mg/s with let’s say 1100usec of open time. With the ability to go to 2100bar and run that exact same open time of 1100usec we can now deliver 220mg/s (example) 📈 that’s a lot more fuel with the same open time and only charge being rail pressure.

Now we a running more fuel, higher atomisation BUT NOT only are we getting more fuel with less open time. We are shortening the open time of the injector so much we are now advancing the timing with out advancing the timing 🧐 SOI (start of injection) BTC remains the same yes but EOI (end of injection) IS NOT, this in affect creates a advance timing all dependant of how short or shorter the on time is reduced and only advancing EOI. So sure a high pressure fuel pump that delivers rail pressure where we want it is great. But there is a bigger picture than just RAIL PRESSURE 📈

Fuel system in a diesel is king and always will be. You can lack in turbo and make more power than the guy with more turbo but less fuel system. This is the Modified Standard 🫡💻📈
