🔧 2025 FORD EVEREST V6 DIESEL SORTED THE REDLINE WAY 🔧

Just finished up this Next Gen Everest V6 and it's a different animal.

What we did:
✅ Manta Turbo-back exhaust
✅ Intercooler + transcooler kit
✅ Custom Redline tune

The numbers:
📊 Stock: 235hp / 613Nm
📊 Tuned: 266hp / 684Nm

That's a 31hp and 71Nm gain - and it's not just a peak number chasing dyno queen either. Check the graph: gains the whole way through the rev range, holding an 80-100Nm advantage over factory from start to finish.

The intercooler and transcooler combo sorts out the factory heat soak issue these V6s cop under sustained load - towing, hauling, hard driving, whatever you throw at it the power stays consistent instead of falling off when it's working hardest.

Paired with that 10-speed auto, this thing sits right in the powerband and just goes like it should've from the factory.

Bulletproof, safe, built to last the life of the car.

Got a Next Gen Ranger, Raptor or Everest diesel & petrol? Come see us - we'll build a package around exactly what you need it to do.

2025 D-Max 4JJ3 in for the full treatment a few weeks back 🔧

Supplied and fitted a GSL Fab 3” turbo back exhaust to get this thing breathing properly, then backed it up with a custom everyday tune tuned in-house on our Mainline dyno. Good reliable get up in it without going silly, exactly what you want in a daily/tow rig.

We also threw in a transmission tune to sort out the gear hunting under load. Anyone who’s towed with a new D-Max or BT-50 knows exactly what we’re talking about, constant hunting between gears is a factory annoyance and it’s an easy fix when you’re in there.

Dyno proven results:
155hp / 499nm stock ➡️ 201hp / 660nm tuned
That’s a 46hp and 161nm gain, all verified on the dyno.

Free shipping applies on tune + exhaust packages, manta exhausts only.

REAL FEEDBACK FROM REAL CUSTOMERS

2021 200 series Landcruiser benefiting from one of our custom transmission calibrations paired with a emissions compliant tune from a couple weeks back. If you’re using a Toyota to tow with an auto, come see us. Engine and transmission tune packages are $1700 drive in drive out. Any diesel, we can tune for economy and more power.

Dyno tuning by itself starts at $1300, we can also multimap but only as a package with turbo back exhausts and transmission calibrations.

Towing has never been better 🤝

Hi everyone, our phone system is currently down today. If you have anything urgent please come by the shop we are open as usual.

We apologise for any inconvenience, we hope it’ll be fixed by this afternoon.

Bit of a shout out to one of our major local supporters, that help us so much in short time frames that shouldn't be possible, with things that we shouldn't be ruining lol.
Redline Automotive and Engineering Brant and the guys continually doing everything they can to keep us on the track in (way) short notice when we need top tier engine machine work done locally! Thanks team, between you and Warspeed Industries engine support, we get to do some cool stuff! You need machine work done right in Darwin, Redline is the only call to make. Can't recommend these blokes enough. Don't say Brody sent you but 😂💙

Another 80 Series in for a custom tune, this one a 1HD-FTE converted to FTM mechanical pump. Just to be upfront, we’re not fans of the FTE to FTM conversion — the factory electronic pump timing and pressure is superior, so you won’t catch us doing these conversions ourselves. But if it’s already done, we’re more than happy to get in there and tune it properly 🔧

This one rolled in stock, running the factory CT26 turbo, making 129hp and 361nm at the wheels. We fitted a Boost T, wound the boost up to 18psi and spent time dialling in the fuel delivery. Ended up with a solid 172hp and 469nm — that’s a 33% jump in power and 30% more torque 📈

AFRs held at a safe 16.7:1 coming on and 21:1 under boost, keeping EGTs in check and the engine protected long term. Reliable power, done right, on our in-house Mainline dyno 💪

Got an 80 Series that needs sorting? We’ll get it running strong and keep it reliable. Give us a call on 08 7918 1433 or drop into 31 Tannadice Street, Winnellie

🔧 2025 Mazda BT50 – Tow Tune Done 🔧

Got this BT50 up on the Mainline for a proper tow tune last week, exactly what the customer was after - safe and emissions compliant with solid gains across the board.

Power went from 158hp to 191hp, that’s a 20.9% increase, and torque climbed from 518Nm to 645Nm, up 24.5%. Theres still a lot left in these things but the customer asked for not too much in it. Like always we tune how you want.

Worth mentioning the converter was unlocked down low on both runs so the torque figures are inflated by roughly 60-80Nm either side, real world gain in punch and mid range pull is exactly what this thing needed for towing duties.

We ran out of time to get the transmission tuned while it was in the shop but it’s booked in next week - these BT50 and D-Max boxes really benefit from having the shifting sorted alongside the engine tune. They hunt gears like all hell while towing.

Everything verified live on the dyno before it left. This is the kind of work we do day in day out here at Redline, Darwin’s home of serious tuning capability, and yeah we still race real cars out at Hidden Valley too 💪

We got some more testing knocked over this weekend in the new car.
Little mistakes here and there but improving every run, we’ll be back again to run our first full passes in it at the next meeting 👌
