Default I may be making a comeback- so help me out - 01-10-2017, 10:38 AM

Im about to buy another DD beater car, and i thought to myself, a 335xi nearly perfectly fits my criteria
-cheap
-AWD
-not too far out of style

So ill probably take my brothers E92 335xi 6MT off his hands

Whats the latest and greatest for best usable HP? I will NOT be running meth, just 93 octane

Im thinking:
JB4 (of course)
Air intakes
Turbo Inlets
**'s




whats a realistic HP for such a setup?

Add a fmic to that list and you could prob see around 400-410awhp with that setup on pump 93. add e85 mixtures and things could be pushed to 450-460awhp. then again, a lot depends on what type of dyno you use and other variables like temperature, ect ect.

Stock frame....lol as in upgraded stock frame or "oem from the factory" turbos? If upgraded stock frame, there are a couple of cars that have dyno'd over 500whp on straight pump 93. One that comes to mind did so on regular 15t size rb turbos.

It's rough on 93 only. Maybe 475whp? You can make more but it gets a little sketchy long term.

No E85 access? With the new port injection kits out that is the go-to fueling. Then no issues up to 600whp on hybrids.

No, you guys are smoking crack. Stock turbos and 93 octane. You'll see about 400 whp at most, and that's because inlets will allow the turbos to peak at around 18-19 psi. They add more head room, about 2-3 psi more on stock snails.
Torque will be a little higher, low 400s. But that's plenty for an AWD DD. You will enjoy it.
If you decide to experiment w e40 you can get to 450 whp on that set-up.

Exactly, stock snail, no matter how you tune it, the whp will drop off like a rock past 6k rpm. Sure, inlet will squeeze out a few more psi at the top end, but the most you can make reliably is around 400whp.

That is figuring hybrid turbos. Subtract 20-40whp for stock ones on 93. Pretty much all the hybrids can swing 600whp on E85. Some up to 700whp when you start to break factory pistons. If you want to spend more money on a flex fuel sensor (not much more work to install if already doing PI) then the JB4 can can adjust its mapping based on your actual mix.

For just 93 I think you won't be thrilled with the platform but if you have something that can at least use E85 when you have access, it's the sort of power you're used to.
