427hp. Through the front wheels. And all of it usable.

MK7 Golf GTi in for stage 3.

Work carried out:
*IS38 turbo supplied and fitted
*New HPFP after the original shaft seal failed and let fuel wash into the oil, pulling the fuel trims rich

Now the intercooler. The customer supplied their own for us to fit. It didn't fit. The finish was rough, no internal air guides, and not a single bit of branding on it anywhere. A cheap copy sold at a serious markup. And it cost them more than the Direnza MVT we ended up supplying, which actually fit, and flows and cools correctly. Paying premium money for a worse part is the worst of both worlds.

Then onto the dyno for stage 3 calibration on Simos18, with our full set of extras that make a real difference on these FWD cars:
*Switchable maps across 3 power levels
*Switchable pops and bangs
*Boost by gear
*No lift shift (manual box)
*Advanced traction control tuning, a big improvement on a FWD stage 3
*Rolling anti-lag

Result: 427hp and 565nm, made on 99RON with octane booster.

Anyone can chase a big number. Getting it down through two driven wheels without lighting them up is the hard part. That's what the traction control tuning is for, and it's why this GTI drives as clean as it does.

If you want a stage 3 that's actually usable, get in touch 🏁

Summer's here and your A/C should be doing more than blowing warm air at you. ❄️

Air conditioning re-gas, diagnostics and repairs — all under one roof in Sheffield.

Our service covers the lot:
• Full re-gas — refrigerant recovered, system vacuum tested, recharged to spec with fresh oil and UV dye
• Diagnostics & leak detection — if it's losing gas, we'll find out where before we fill it
• Repairs — condensers, pipes, compressors, seals, sorted in-house
We handle both R134a and the newer R1234yf, so whether your car's a modern daily or an older classic, we've got you covered.

Not just for comfort either — a healthy A/C system clears your screen faster in winter and keeps the whole system lubricated.
Ice cold in one visit. Book yours in 🏁

125,000 miles. Down on boost, clogged up, and juddering at low speed.

This 420d xDrive left a different car.

The full job:
• Replacement turbocharger + exhaust manifold repair
• Walnut blasting + swirl flap delete kit
• EGR and EGR cooler delete
• Stainless downpipe
• Stage 1 engine tune
• 8HP transmission tune - faster shifts, better lockup strategy
• 8HP45 gearbox service, transfer box service + calibration
• Engine oil service, new rear shocks and top mounts

On the dyno: 176.8bhp / 348Nm before. 208.5bhp / 406Nm after. And that's against a healthy baseline. We ran it after the mechanical work, so the gain over how it arrived is bigger still.

Ramair replacement filters — available for every intake kit.

A foam filter is there to improve intake airflow and efficiency, but they don't last forever. The foam deteriorates over time, and once it does you're giving away the very gains the kit was fitted for. The photos show the difference — same style of filter, a few years apart.

We can now supply the correct replacement filter for any Ramair intake kit. Not sure which one you need? Send us your kit part number, or just a photo of the intake, and we'll match it for you.

Two options:

• Posted straight to your door
• Supplied and fitted here in the workshop

Get in touch to sort yours 🏁

Wagner Tuning Competition Intercooler Kit installed on this beautiful Toyota GR Yaris.

Toyota’s aren’t common in our workshop, but when track friends need track parts, we’re more than happy to supply and fit.

If you need performance parts for your car, get in contact. We’re suppliers for both big and small manufacturers of performance parts, with more than just those listed on our website.

Wagner is undoubtedly the highest quality solution we offer at JBM, with OEM-level fitment and the performance to match.

The intercooler is designed to improve charge air cooling and reduce intake temperatures under sustained load, making it a popular upgrade for tuned and track-driven cars.

One of our customers’ Audi S3 8V got some good upgrades and is now Stage 2 ready: Direnza intercooler, Trackslag downpipe and Cobra Sport cat-back. They’ve already got an intake done with upgraded intake elbow, so they’re all set.

Although the cat-back isn’t mandatory for stage 2, it sounds brilliant and will help extract some extra performance.

If you want to keep costs down, intercooler, intake, elbow and downpipe get you there. Pick what makes sense for your car and budget.

You don’t have to use the same parts seen here. Pick your own combination. We are suppliers for:

• Direnza
• Wagner
• Airtec
• Milltek
• Scorpion
• Trackslag
• Cobra

Unsure what to go for? Message us and we’ll point you in the right direction.
