Infinit Performance UK 🏁 Home of the World's Fastest McLarens

20/07/2026

After a break from half mile racing in the UK, we’re back and what a way to return.

Our Stage 4 McLaren 765LT recorded the fastest pass of the entire weekend, running 204.6mph in the half mile. 🏆

What’s even more impressive is this was achieved on low boost. The data shows there’s 210mph+ in the current setup, so now it’s time to turn it up and see what it’s really capable of.

This isn’t a one hit wonder, it’s a properly engineered package. Featuring a fully built engine and gearbox, Dodson clutch upgrade, upgraded fuelling, M-Tuner ECU calibration, motorsport traction control and boost by gear strategy, it’s built to put power down reliably while still driving like a road car.

A huge thank you to everyone involved in making this happen and to the organisers for another fantastic event.

204.6mph on low boost. Time to turn it up. 🚀

Not every knock means engine trouble.

This Stage 4 McLaren 765LT came back to us with a front end knocking noise. After carrying out a full diagnosis, we traced the issue to a failed front shock absorber.

With the car running upgraded Powerflex suspension bushes, it behaves differently to a standard setup, so it’s important not to jump to conclusions or replace parts without diagnosing the fault properly.

A systematic approach saved time, avoided unnecessary repairs, and got to the root cause.

Performance modifications change how a car behaves, which is why accurate diagnosis is just as important as quality tuning.

Don’t miss the sound check at the end 🔊

One thing a lot of people underestimate is just how much of a difference a downpipe makes to the sound.

This DNWA RS3 has just had our Stage 1+ package. While you’ve been seeing more of our McLaren engine builds lately, the RS3 isn’t going anywhere. It’s still our bread and butter 🔥

Water m**h isn’t just about chasing power. By reducing intake temperatures and increasing knock resistance, it allows for safer, more consistent performance. As a bonus, the unburnt fuel can create natural flames under load and not the artificial, mapped in flames that put unnecessary stress on components. 🔥💨
