Can anyone tell me approx how much hp im pushing?

2011 bmw 335xi
Pure stage 2
JB4 Map 5
93 octane
Injen intake
VRSF Catless dp
upgraded chargepipe (forgot what brand)

Thanks guys, i'd appreciate it I just put the turbo on last night so im wondering how much im at.

Jb4 only map5 no back end flash?

I got around 355 whp modded and 265 stock on a mustang dyno. My car was on Canadian Chevron 94 which is prob same as 91 in the states.

If u get a custom mhd tune, you should hit 380 whp?

pretty sure im at more than that tbh, and no, no back end flash yet.

I think 420ish whp is the max on normal 93 fuel or so for the PS2 Turbo.

If you can afford the PS2, don't cheap out on tuning.

If you don't know what you are doing get someone to either A.) Create a custom BEF for you. or B.) Get a custom MHD tune.

Don't spend $2500 on a turbo just to watch your car go down the drain because you were to cheap to properly tune it and log it.

You probably aren't much more than FBO if that right now. JB4 stand-alone boost targets are low.

Since map 5 has variying boost target and I don't know what your timing looks like combined with the fact that you're a Xdrive car I would say about 390 awhp.

[Unknown_Car]

You should be about 420-450whp on ps2. Add some e85 and get a custom map 6, and you will easily will be over 500whp.

You're leaving a ton of power/throttle response/smiles on the table.

Please, please get a custom BEF at the very least - otherwise you're pretty much throwing money in the garbage.

6MT or 6AT?

If you don't know what your peak boost is at any given RPM, we really are just completely guessing...

My N55/PS2 makes 500whp at 23.5psi @ 5700rpm. With much losses through the AWD/6AT drivetrain. For reference, at 20psi, it makes 450whp @ 6100.

On a RWD 6MT platform, 560-580whp could be attainable.

Mods: ER fmic, ER cp, vrsf Catless dp, fuel it PI, ps2 + inlet + dv upgrade, stage 2 walbro 525 lpfp, intake, occ.. etc.

It being a mustang dyno.. id say it’s probably 420ish AWHP on 93. Maybe 500ish AWHP on E85.

Why are you finding dead threads and bumping them with this?

Question of the day is: Did Allen ever get the BEF?
