Should I go with twins or a single for this power goal? I wont be running e85 so I need some help with picking fueling mods. Do I need PI at this whp? Also, should I run meth or not?

Between single or turbo upgrade is not the issue. The fuel is. Your going to struggle to hit those numbers on just pump gas with no Ethanol.
Maybe meth would help but I am no expert with meth kits.
Have your purchased a 335i yet?

No sir, simply planning and looking at options and figuring out what I would like to do. Would I need PI at this hp level?

Not enough octane on pump. If I was stuck with pump fuel I would run port meth with like a 80/20 mix to keep the octane high.

What are you planning to do with the car and what kind of powerband do you want?

[Tyc0]

I plan to be hitting somewhere around 500 with RB twos on pump, but I've been told that's about as far as I can go without higher octane. So you will definitely need meth to get above this number, but once you have it you can probably go farther than 550..just depends how much meth you want to spray(how much money you want to spend)

Following. Would like 550whp to with twins with no E85 (No E85 at gas stations). Figured meth but it seems expensive for the 100% safe systems...

Didn't look like he needed meth

[mike@x-ph.com]

twin-turbo for the extra tq

[Rube]

what about fuel delivery? Would you need at least a dual intank pump with 1 of the pumps operating off a hobbs switch?

I've got a meth system on my mini Cooper S..... although the tune doesn't require meth to be "safe". From the experience I've had with my meth system, I would never want a tune that required it for extra fueling purposes. Over the last few years I've had a pump die on me, solenoid valve stick, fuses blow, etc,etc........any one of those things would have been bad news if I was running that in my 335i for extra fueling. It would have went way lean, probably done some damage to the motor.

Meth systems just add more components that can fail.

But then how much WHP are you adding if you tune isn't around the meth? But yeah I agree, for example if a injector clogged up the engine could go. That's why I'm not really into the meth.

Probably none....or very little. It's more to cool the intake charge down on hot days (the top mount intercoolers on those heat soak really bad) to keep it from having a bunch of timing corrections, and bump up the octane a little bit for when I can't find 93 fuel. It actually does what it's supposed to...most of the time.

Highway monster. Mostly top end power

I don't have access to e85 in Canada. Meth is the only option.

Oh ok... I guess no other solutions to no E85? Guess I could get some from time to time.

Single turbo then. For what its worth. Not saying it would be the safest setup but recently with a 6466 they hit 670whp on 94pump gas. So 550whp with a single turbo on pump is doable. With the correct turbo size of course.
I would recommend checking out other forums such as SS for more info on ST setups though rather than here.

[Hirammguzman]

Im pushing 556whp on the dyno.

This is the mod/upgraded/maintenance list
Vrsf Chargepipe
Tial BOV
ARM 7” Intercooler w/ Upgraded Hoses
MMP Catless Downpipes
SSR DCI
XHP Trans Tune Stage 3
BMP Stage 3 Dual Walbros 450s w/ Boost Ref Harness & Hobb Switch
E85 MHD Custom Tune
N20 3.5 Bar Tmap Sensor
VRSF 2” Inlets
NGK 97506 Gapped to .22
Precisión Raceworks Coil Plugs
VRSF Oil Catch Can
RB Turbo Upgraded PCV
TD04-19T Upgraded Twin Turbos (EBay Turbos)(Still running great after 12,000 miles :0 )
BMP Port Injection kit W/ AIC 6 Controller
Precision Raceworks Feed Fuel Lines
Rear tires (265/40/19) (Michelin PS4 S’s)

I abuse the car on the daily , just make sure you do all maintenance beforehand so you won’t be left stranded. With this installed, you’ll gap many people
