Have a 2010 335i. Mods are:
Vrsf front mount.
Vrsf catless downpipes.
Cpe charge pipe.
Bms dual intakes.
Walbro 255 inline fuel pump.
Alpina flash.
Custom BPC Tune.

Car makes 380/420 currently.

What would the car make if converted to straight e-85?
What would be needed to convert and run safely?

These are your mods. Vrsf front mount is what, an fmic? Size?
E85 straight with your current mods, maybe 30hp. Fbo, 75 hp.
You want in order to add power
7" fmic
Inlets
Better tune Youll be 450 rwhp here

Stage 2 Turbo upgrade add 50
Outlets add 25
LPFP add 50 with e85
Fuel rail add 50
Bigger turbos or single
Built motor.

More than this requires better than stage 2 turbos. Doing the improvements out of order will not get you the same gains. For example, outlets will do zero gain without turbos as they improve air flow, but the stock outlets have plenty of flow for stock turbos. Only with bigger turbos do they become restrictive. I've done all the above except built motor which is next.

The e85 will make some additional power without pi but you'll do much better with gains if you follow my order of improvements. Theres also little things thst need to be done after fbo. Extra tuning, hobbs switch, fuel lines, etc, etc ,etc.

[Fundguy1]

Currently planning built motor.

Thinking about
-rear camber rods

Rb inlets, vtt outlets, lpfp, fuel stuff etc are the additional mods you have vs. me and obviously a tune then correct?

Ok gotcha. From what I can from you just changed the pump.

I have the 7'' vrsf FMIC.

I guess I need to add inlets. What are those?? Lol.

When you say "better tune" it that with the e50 mix and inlets to hit 450rwhp?

I told BPC I wanted a conservative tune on 93. I know there dyno reads low aswell so I'm happy with 380/420 although I don't really know what they should make with my mods and 93 through a auto.

This is my DD so I do not want to go crazy, no aftermarket turbos or built motors. I'll keep that for a vette.

[Camonly]

FYI this is a awesome thread. Thanks for all the info for the newb dumb domestic owner.

[Fundguy1]

Lots of brands of inlets. Heres one.

Why would you want a conservative tune but also want e85 race gas? 450 is what fbo and a good tune do on pump gas.

Car would make about 420hp/500ftlb

Your inline pump that you currently have will be enough to support e85.
It might struggle with e85 but you only need the octane of around e60 to max out your stock turbos.

All you currently need is a custom tune.

Less than it would make on E60.

I wanted a conservative tune on 93 since it's 93. Hotter, detonation, I beat on it daily and it's my DD. Which is why I want e85, more power, colder, higher tolerance to detonation can run more timing =safer power. And it's cheap.

[screaminfast]

I made 400/450 on a mustang dyno with the mods in my sig, running 10 gallons e85, the rest 93. I upped it to 11 gal e85 now, but i might only gain some torque from less timing pulling on the dyno.

You definitely want inlets/outlets.

You won't be pushing it on a hot tune on 93. The turbos would go before the engine. E85 is more expensive than 93. Yes its cheaper by the gallon, but you get less mpg and in the end you spend 25% more per mile.

DFW:

93o $2.70/g
e85 $1.99/g x 1.3 (30% factor for e85) = $2.59/g

It's really a wash in TX (it will be different in different states due to state fuel/road tax variances). But if you want to know the cost factor just multiply your e85 cost by 1.3 and compare it to your local 93o costs...you'll be within spitting distance of the end result (cost wise).

But the REAL value in e85 is coming. Get a good, conservative MHD 93o tune. Get a good e85 MHD tune. Then here in a few weeks/months when MHD and Motiv release their full flex fuel tune you can load both into one tune and have the care extrapolate between them via ethanol percentage. I.E. true flex fuel.

[Fundguy1]

Thats what im doing. Flex setup next.
