    Yea i get ya with the stock turbos. Basicly boost is resistance to flow and creates heat. The stock turbos at some point just become hot air pumps and that's where they get band-aided with meth.
    Would a set of upgraded turbos cause more of the same or could you run a set of stage 2 turbos and get close to the performance im lookin for minus the meth?

    Hybrids on pump gas won't make 450awhp, if that's your ultimate question. Stock frame turbos of any kind wont make that on pump gas, the bottleneck on the exhaust side is too severe and you don't have the octane for aggressive timing. Now you won't need a ton of octane, some E85 would get you there. No "need" for meth to make those numbers.

    You'll make 449.4awhp with that setup so no.

    Hahaha I know just not quite ready for that yet. Waiting for more data on some of the new turbo options although i'm pretty sure some of the newer options I will no longer consider after doing some reading. Need to save up some $$ though but possibly next spring/summer

    My guess is the pump is on its way out... Speaking of that do you know the part number by any chance?

    Next question... Does anyone make a single kit that works with the awd cars or are they only rwd so far?

    FFtec does. In fact the only 335xi with a single turbo replied to you in this thread (idspeedskater)

    450whp on an XI recipe on the cheap:

    1) BimmerBoost flash (free)
    2) Intake (BMS DCI)
    3) Downpipes of choice (I like BMS for price/quality ratio)
    4) Intercooler of choice (VRSF 7" is the cheapest good one)
    5) Hybrid turbo's of choice (RB/VTT stage 2/ASR)

    Now for pump gas ONLY- you may want meth.

    My suggestion: E85
    6) Gas cans so you only have to drive the 50 miles on occasion. It's not that bad since you really just need a mix.
    7) Walboro in-line fuel pump to assist in E85 use

    Extra's you might want to consider, but not explicitly necessary for your goals:
    8) JB4 or Cobb (JB4 is cheaper and makes things much friendlier tuning wise, Cobb is great for protunes)
    9) Chargepipe and divertervalves/BOV
    10) Oil catch can
    11) Better clutch
    12) NGK spark plugs (1 step colder)
    13) Intake valve cleaning
    14) Obama sucks bumper sticker (You're in the east coast that should piss off everyone staring at your bumper as you pull away)

    If you do all the work yourself and catch a few deals you could probably get everything including the optional for around $5,000 not including the clutch. Or you can spend more on fancier products. Good luck.

    @V8Bait, no one is going to hit 450awhp on BBF without a piggyback. Cobb is currently the only flash capable of putting up those numbers.

    Because of ultra secret cobb only tables? I love Cobb... I had one for a few years before a friend "borrowed" it... but I can do the same tuning in Tuner Pro that I could in ATR it's just more annoying and lacks shiny factor and decent logging (the BT logs are meh).

    I recommend Cobb for anyone that doesn't want to get a piggyback because open source is only good for those that wouldn't be asking, but what you said just isn't correct :-(

    What's up with the Cobb crusade lately. Because Vishnu is out we need to do tunerwarz 2.0?

    450awhp has been done and even more 460-465, but it stresses stock turbos. It could be fine for daily driving and occasional bursts, but serious racing for a few laps could kill the turbos.

    Could it be because Bimmerboost flash needs just a cheap cable...

    Not secret tables but because of proprietary logic. You're not pushing past 18.5psi with any other flash options out there.


    You're also not hitting over ~430whp on anything but a unicorn dyno. ~470whp dynos are put out there for advertising purposes and nothing else.

    You can make 450whp on 18.5 psi with rb turbos just fine with the right fuel and setup, this isn't a stock turbo thing I didn't think. Ok- maybe he'll be a few short, and he won't be smashing 500whp, but it's gonna be close. Hasn't this been done on dynojets for a while now? Sure dynojets are more unicornish than mustang dynos but it's not like they shoot glitter after every N54 finishes a run...

    I know he's an XI but he's also MT so he shouldn't be that far off from a typical auto dyno. Maybe an extra few percent loss, it's negligible. 430-460whp is what I'm used to seeing at 18.5 psi, automatic XI's round out the bottom and RWD 6MT's cheat our way to the top of the queen chart. Although most I've seen have been stacked and 19+psi is much more common I guess, maybe it's late and my memory is off. Wouldn't be surprised.

    Yes, RBs should get there. I was thinking stockers for some reason.

    Because i havent seen a single OFT, BB push more than 14psi past 6k rpms. Sorry, but you are not going to hit 450awhp even on RB's with that low of boost. Wedge was trying to increase boost in the upper RPM's, as was Shiv with his OFT E30 maps, but they failed. The only way OFT and BBF users are currently making power (without piggyback) is to run 16* of timing on a mild boost curve on E85. Until i see OFT/BBF users keeping at least 16psi past 6k rpms, i see a bleak future...

    I challenge any OFT/BBF flash only user to prove me wrong.

    You piggyback guys really don't observe much do you Click here to enlarge

    Care to show me a non Cobb flash tune that can push some decent boost up top? Do you really think Cobb and BBF are equally capable?

    That may be correct, but not too relevant since the best results come with piggy & flash combo. Iceberg, who is one of the 460awhp guys, hits more than 14psi at 6000RPM easily with the piggyback, so he has no need to hit it flash only. Btw. the peak power is made before the 6000RPM.

    I wish I had the time to accept that challenge! I don't see why it's not possible, I've put a few very mild tunes on friend/family cars (less aggressive than Shiv's stuff, I wasn't a huge fan), and things seemed to react as expected. For high boost curves I don't know personally since I use a JB4 to target boost, but I don't understand why it would be overly difficult other than you'd probably need to delve into the PID tables, which I like to stay out of for the most part. But now I'm talking out of my ass since I've never tried to target that much boost past 6k rpm considering I shift there anyway.

    I can tell you that us experienced ATR uses attempted to help the BBF/OFT crowd run more boost when they began experimenting, didnt work. The tables you massage in ATR don't have the same effect on tunerpro/native DME. It rather quickly becomes obvious that Cobb did a lot more than just table discovery, they truly do have custom logic on the DME.

    I think BB and ATR are basically the same in potential... Cobb does have altered boost logic for a select few that has advantages.

    I'm a piggy-back stacking kind of guy. I'm not sure that I've ever really had any issues pushing big boost (for stockers anyways) numbers past 6krpm.


    Oh gosh darnit - I have datazap logs that I can't post until I have 5 reps. I never realized how much I've been lurking on this particular forum. How the crap do I share these?

    On E85
