1.4L 68HP Van to 200HP+: A Turbocharged Adventure
Got a humble 1.4L 68HP van and dreaming of pushing it past 200HP without swapping the engine? With some bold imagination, a massive turbo, a nod to Volvo’s engineering, and a willingness to embrace a never-ending project, it’s possible! Here’s how this underpowered van was transformed into a torque-hungry beast, with some extra details on the build and its quirks.
The Setup: Big Turbo, Big Dreams
To achieve this power leap, the van was fitted with an oversized turbo (relative to the 1.4L displacement) paired with a large front-mounted intercooler. The turbo is dialled up to a whopping 42 PSI of boost. An external boost controller gives the driver full control over boost levels, allowing for fine-tuning based on driving conditions or mood. However, with great boost comes great lag—boost only kicks in hard just shy of the rev limiter, making the power delivery a bit like waiting for a rocket to launch.
The Volvo-Inspired Power Pulse Magic
Enter the Volvo-inspired Power Pulse system, a game-changer for taming turbo lag. This setup uses a high-pressure air tank (up to 200 PSI) to blast a controlled burst of air into the exhaust, spooling the turbo much earlier than it would naturally. The result? A noticeable reduction in lag and a surge of torque where it’s needed most.
How does it work? A button on the gear shift triggers the system, releasing compressed air from tanks mounted in the rear of the van. On a dyno run, the technician activated the system at 3,000 RPM with a limited charge, and the results were impressive: the turbo spooled significantly earlier, delivering a meaty torque curve that transforms the driving experience. Without Power Pulse, the van would be a laggy mess; with it, it’s a thrilling, if unconventional, ride. However its possible to activate the system at any RPM and vary the amount of air delivered.
The large intercooler keeps intake temperatures in check, but sustained high boost requires careful monitoring to avoid high inlet temps.
The stock drivetrain wasn’t thrilled about the newfound power, so a heavy-duty clutch was installed to handle the torque.
Absolutely! The Power Pulse system makes a tangible difference, cutting down lag and delivering power more predictably. The dyno graph tells the story: with the button pressed at 3,000 RPM, torque comes on strong and early, making the van feel far more responsive than its 68HP origins suggest. Peak power? It’s comfortably over 200HP, though exact figures depend on boost settings and fuel quality (premium fuel is a must!).
Is It for Everyone?
Nope. This setup is a labour of love, not a daily-driver solution for those without at least some skills to fix the vehicle themselves. The turbo lag, even with Power Pulse, requires patience and skill to manage, and the engine’s lifespan under such stress is anyone’s guess. Maintenance is intensive—think frequent oil changes, constant boost leak checks, and keeping an eye on EGTs (exhaust gas temperatures). But for enthusiasts, the thrill of transforming a grocery-getter into a turbocharged monster is worth it.
Why Do It?
It’s a wild, budget-friendly project! If the worst happens and the engine grenades, a replacement 1.4L can be sourced cheaply and swapped in easily. The van’s lightweight chassis makes it a perfect canvas for this kind of mad-scientist build, offering go-kart-like fun with the right driver inputs. Plus, the looks on people’s faces when a small white van smokes them off the line? Priceless.
Is the vehicle going to win an award for the worlds most reliable vehicle? No
Is the vehicle going to win an award for the most finished project? No
Will the engine blow up with the high boost? Quite probably
Is there room to improve? Yes
Where next? A more sophisticated power pulse system to increase low end torque.
Why use Llandow Tuning?
We’re up for whatever project you’ve put together. We aren’t a one size fits all off the shelf map kinda place. We don’t use Davinci or WinMAF like our less skilled competitors, we don’t operate a load of agents or run a "file service" and devalue our brand by doing the whole OTS thing.
We’ve never been a reseller of another tuner let alone a franchise.
We don't offer flash tools or "training courses" on how to plug in a flash tool in to a car to unsuspecting idiots dreaming of being tuners that then go around in vans peddling OTS sh*t.
Whether it’s a motorsport vehicle or a fast road car I’d like to think in our 21 years of doing this kind of thing we have at least some skills to help.
