I've owned my 2018 Superb 280 L&K from new, and I thought about changing it last year, but there was nothing I fancied (in my price range).
Since I love the car, I decided to stick with it, but looked into getting a bit more power out of it.
After shopping around, I went with a couple of local businesses here in the North East of England. Firstly I went for a turbo back custom exhaust system - 3 inch bore, sport cat, back box (and hence valve) delete, and large central silencer. It's a bit loud for me (actually it's more the resonance), so I'll probably get this sorted in the future.
Next, I got a Forge Intercooler, Ramair Induction Kit and Forge Muffler Delete fitted. Then it went on the dyno.
I ended up with 396bhp / 526Nm (graph attached), which was pretty much where I was aiming. It was a relatively warm day when it went on the dyno, so on a colder day it possibly could have done just over 400bhp.
Unfortunately, just before Christmas, my stock turbo went up in a cloud of smoke. Since then it's been in the garage, where they've mainly been waiting for parts.
I've now had fitted a new Garrett Powermax Turbo (Stage 1), and upgraded HPFP, with it ready to go on the dyno next week. I'm hoping for about 480bhp, but time will tell.
The biggest delay they've had though is in trying to source an upgraded LPFP. They initially thought a Golf R / Audi S3 one might fit, but this proved incorrect (hence my question to you earlier).
They're going to map it with the stock LPFP in place, but if this proves to be the bottleneck, I wanted to better understand my options.
