Wanting to max power, expected gains?

So as title suggest, I'd like to just see what other's experience is with my shared platform and what the highest/expected gains are

I drive a 2014 428i xdrive with an n26

If I were to go full bolt on, say max out everything I could with out touching internals, new turbo, the lot

What am I looking to get power wise? And on another note, what's my mpg go down to?

Wow that's not a lot. I guess I'm expecting a little more from what I've seen

Depends on fuel. I think pump gas is 280 whp max, ethanol mix 300 whp max. Wouldn’t expect anything more than these numbers.

No matter what you do there's only so much you're going to get out of an N20/26. If it was only 170HP bone stock like a Toyota Corolla there would be a lot of room for improvement, but it's not.

Yeah that makes sense. I've got 93 luckily in my town as well as my state for the most part

Thanks Mike!

I'm a little confused though, what is PWG and EWG?

And I have an n26, would that lower the top end by a significant margin?

PWG is pneumatic wastegate (older models)

EWG is electronic (newer models)

Got it ok, that's a little more what I was expecting. So what does it take to go from 300 to 382?

Full bolt ons, larger turbo (MHI, pure stage 2, hexon turbo). Otherwise you might be able to get really close with FBO and a 100% e85 tune.

FBO:

Catless downpipe
Axle back exhaust
GFB+
Turbo inlet
Intake
Chargepipe
Turbo to intercooler pipe
Intercooler (Wagner comp 2, Evolution raceworks, ATM, CSF, turner Motorsport)
Tune (bm3, JB4)

custom tune.

Good luck.

Something to be aware of is when you aim to go further than 350whp, it's advised to change rods and bolts minimum as the rods and bolts are known to let get above that range. It's the nature of the motor having full torque available below 2500 rpm.
