Hello, I have a 2011 n55 6mt car and want to make 500whp reliably. Just put a new motor in it with 50k miles and did king bearings. Car has inlet, outlet, catless downpipe, Vrsf street exhuast, turbosmart bov, 7.5in race intercooler, bms intake. I also just put a xclutch organic clutch so it can hold 800tq. I’ve seen that pure stage 2 or slightly bigger turbo kit like bigboost is an option but I just love the sound of the big turbos like 6266. What turbo kit and fueling would you guys go with looking at dg autowerks top mount or speedtech bottom mount. Keep in mind my motor is stock.

Check out 4n motorsport bottom mount n55 kit (it's listed under the n54 section on their website). I'd like 500 whp on 93, I think this kit with a BW efr 8374 could probably do it. Looks like a great option but I haven't found many details yet. I'm waiting for some guinea pigs to try it first out and report details on the forums👍

Also, pure just launched the pure 750 for n55, but not many details on the forums yet.
There’s an (EWG) M135i in the UK that has done a 5.51 second 100-200 on E50 plus meth’ with the Pure 750, so they can move!


Edit: It was an Instagram story annoyingly, but it’s on the Dragy leaderboards!

Dang. For comparison, what ballpark is the fastest 100-200 PS2 you've seen?

Pure says the pure750 spools 400-500 rpm's sooner due to the cast manifold, but sooner than what? Sooner than PS2? Or sooner than 750 prototypes they tested that didn't have the cast manifold?🤷‍♂️ I'm really anxious to start hearing some PS2 to 750 comparisons..

An oldie, but a goodie.

I’m happy to be corrected, but I don’t think an N55 PS2 has broken into the 5’s for a 100-200. Mid-6’s is damn good going for a PS2 from my understanding.

I’m assuming than the PS2? That would make the most sense. The PS2 (V3?) is also a 9 blade compressor, so it would make sense that they are comparing the 7+7 from the 750 to that. I agree it’s a bit ambiguous though.

Edit: Peter did a 6.26 second 100-200 at one point, I think on E40 plus meth’.
