Hi, I am new to bmw's but not modding and not new to high Hp cars.

So I am working toward a couple stages...
Car is a 2008 335i coupe manual.

1st stage is 600+ WHP ( W/ 91 OCT & meth would be preferable ) and my 2nd stage next year after taxes will be single turbo and 700+ WHP
Here is the current mod list:

* MHD tuner
* JB4
- Precision Raceworks N54 Ignition
- Spark plugs-N20 spec
- New LuK dual mass flywheel
- New LuK 550i/335is clutch
- Frankenturbo F21b's
- Lines Racing stainless steel dual 2.5" exhaust
- 3" catless down pipes
- VRSF 7" intercooler
- VRSF charge pipe
- TiAL 50mm blow off valve
- Fuel-It! Stage 3 bucketless in tank pump
- Custom oversized Oil cooler w/Mocal 180t-stat
- Dual catch cans for high and low PCV
- N20 3.5bar map sensor
- New index 12 injectors
- Snow Performance Stage 3 boost cooler
- Snow performance water/meth flow gauge
- Snow Performance Fail safe
- Snow performance 2.5 gallon tank
- AEM water meth pump/filter
- Pro-Meth direct port water meth system ( 1 injector per runner and 1 in charge pipe.
- Burger Tuning clutch delay valve delete
- Burger Tuning clutch pedal stop
T-urner Motorsport street engine mounts
- ECS tuning street trans mounts
- M-Factory Limited Slip differential
( alot more mods that have nothing to do with power )

My question is what will I need to add or change to make my first goal of 600whp ... keeping in mind that anything I add from this point I don't want to have to upgrade AGAIN to make the 700whp.

I was thinking of a HPFP and/or flex fuel setup.... not sure if its needed to make 600whp though.. I don't want to buy anything that is NOT needed to make the 600whp, so if PI is needed for 700 but not for 600whp then I will wait on that till I start the single turbo project. But if I have to buy for example injectors for 600whp, I want them to be large enough to suooprt 700whp so I do not have to buy another set to make 700.... ( hope that helps get my point across )

Any suggestions or thoughts would be great.... I have searched and searched but soo much info is out there and none seems to fit my current setup, or i have just missed it in the huge info download that my brain has been doing.

I bought the car with its current set up so please no frankinturbo bashing, I know they are a nono. ( at lease thats what I read )

Thanks ahead of time...!!

S3 LPFP & Inlets/Outlets?
Everything else looks good, how are logs?

you suggest changing the stage 2 LPFP to a stage 3 for 600whp?
would a hpfp be better idea ?
No logs for me yet, it was lightly tuned by wedge tuning before I got the car and is going to be dyno tuned on 3/13.

Depends on the octane you're running, but I usually see people upgrade to a S3 after 550whp. I don't think you can hit 600whp with only a s2 lpfp. HPFP upgrade such as VTT shotgun would be a good choice to secure the rail pressures. I would only use meth for its cooling properties at this point. I don't run meth, but others may have different opinions than me.

This is your stage 1 lol? In that case I must be at stage .4, I'm jealous!

Reconsider your 335is clutch and flywheel - you'll need something stronger to handle your power goals.

[Torgus]

you pick the shittiest turbos available and stock flywheel and clutch? you need a real clutch upgrade and flywheel #1 or you will have the fake misfires issue.

If you are going with running that much meth why all that snow stuff vs, an HS4 that has it all built in and designed to work?

So does your car already have this all installed or are you planning on running this? If it is all installed just go dyno, your post is confusing.

I did not pick anything. ( just bought car like this with ALL of it already installed).
My question is simple.
My short term goal is to hit 600whp. I want to know what I need ON TOP of what Is already installed. I will be going to a single turbo next tax refund season and trying to make 700whp. SOOO if I buy anything to put in now it needs to work with the 700whp goal as well, I do not want to buy twice.

So it seems that the suggestions so far are :
1- upgrade the clutch
2- go to stage 3 LPFP

This should be enough to hit 600whp???? ( if the worst turbos in the world will do it )



I come from the Subaru STI world and am trying to get the Idea of what is NEEDED to get to 600whp here in BMW land.

If you go single, you may want an intercooler upgrade. Have you done logs/have access to logs? If IATs are going north of 120, you might want a bigger stepped intercooler.

For your single setup, you'll also want different o2 sensors, mac solenoid/boost box, if your single kit doesn't come with those bits and pieces. I've also read many people have overboost issues due to 1) having insufficient vacuum hosing diameter 2) wrong BOV spring weight.

Thats not really the question, at lease not as simple as that. ITs MORE along the lines of .... Is my set up good enough or if not what needs to be changed. I do not want to get tuned on the dyno and hit 550whp when I could have added a few more correct parts and hit 600.
Please read THEN bash
Again I am only seeing that I prolly should upgrade to a stage 3 LPFP and upgrade the clutch.

Side note: I really do love that smiley smacking the other. makes me grin

If that is your current mod list all you need, in theory, is a different clutch and flywheel and a tune on a dyno and you should hit 600whp. You do not need more low pressure fueling as you are not running PI.

Just fix the clutch, tune, and dyno. Fuck FT claims you can make 600whp on 93 so if you believe his lies you don't even need DP meth(you do and you will)

Awesome, thanks for the info Yeah I have read NOTHING but bad reviews of these turbos... I just hope they don't take my motor out with them when they go

[N54Society]

Why are you going with Franken turbo and which FMIC? Also, as others stated, you will burn through that clutch/flywheel setup quickly at those power levels. I felt slipping at close to 480whp/500wtq on e85 (mods in sig) with a 335is clutch and single mass flywheel in some instances for brief moments. Sold the car before it got worse.


Edit: Just read that you bought the car with these mods. Never mind on the turbo question.

[Jeff@TopGearSolutions]

You're going to need upgrade the clutch to at least Spec Stage 3+ if not a Twin Disc.

[JM98]

The difference between a reliable 600hp and 700hp is about 10k. Definitely something to consider when looking at your goals with this car.

Question:

I have upgraded to the Stage 3 LPFP ( dual walbros )
Would adding a Flex fuel sensor and running a E85 mix be worth it ? When will I max out the stock injectors or stock HPFP?
Maxing out the stock injectors or HPFP with E85 is my concern. I already have PI meth injection and want to keep it.
