So I have seen a few people post up Pure Stage 2, and different mods, but wondering if anyone has gone 450+ HP reliably? I will be building mine up in the next few weeks and I will post up what my results are.

To start with, I have an ER Chargepipe, ER Catless Downpipe, BMS Intake, Wagner FMIC. I run and approx. E30 blend. On a Mustang dyno, JB1 on Map 1, I am 336 HP.

In the order process, I will be adding a Pure Stage 2 Turbo, Fuel it PI plate, Fuel-it Stage 2 LPFP, and considering a small addition of Meth to assist cooling (I am in AZ, and summer ambient will be 100+ every day).

Who else has a seriously modded F10/N55 car? What have they achieved?

Hey, you're local! There is a person on the forum who has a low 11's 535.

This week I also pulled the stock rims, and I had put on those M5 Stock Wheels (20x9 et34 front and 20x10 et 34 rear) that had been powder coated black. It's time to get off the stock config and RunOnFlat Tires (Dealer replaced previous set) and get something that will hook up better. On my 336HP I could brake those away at will and they were a bit slick on a hard launch.

You're right I think that is an N54.

Have you seen the speedtech turbo kit? Not sure if that works with a 535 though:

I believe their kit is only for 335i at this time.

I have to give Props to @Steve@Fuel-It! , he has been a great resource for me to bounce ideas off on what would be the best way to go. Soon it will be coming together. I was hoping to be ready for NFZ in a few weeks but that will be too close.

Those wheels look great Alan.

I've got a couple things done :) I don't know exactly what I'm making though, and I still have a ways to go with the tune before I'm maxed out. If you trust Dashcommand I'm making 460hp / 535 tq. I'm still on straight 93 pump.

I've seen and appreciate all the build threads you have posted. I didn't know if you had run it on a dyno yet to see what it was making or on the track. Are you adding supplemental fuel?

No, still on stock fueling system. I intend to explore limits incrementally and upgrade as needed. @Alex@abrhouston and I are working on a dual HPFP solution for N55 cars to push them well into tranny-killer territory without resorting to port/meth injection silliness.

I'll run it on the dyno when the tune has eeked out every drop available, until then the numbers would only represent wasted money.
