Vf Supercharged On E85

[JohnEastvold]

I have a few leads out as far as fuel systems go and they all come back to what drew had originally mentioned to me. Add a second fuel pump and have a hobs switch so it only turns on when needed. For me i would probably set it to turn on around 5/6 psi. I dont run lean till 7500 and thats at 7/8psi.

Interesting. Are they suggesting adding a Walbro in addition to the the stocker?

Going to give to give this a shot. Twin 450 and a hobs switch on id1000's

Awesome. Looks like the stock top assembly but with two pumps. Does that drop right into the fuel tank?

Who'd you get it from if you don't mind me asking.

A guy i know knows a guy whos done this. Hes getting me it. I can honestly say i dont know much more than that hahaha. Will post up results and more as i find out!

This should be good for stock rod bending or stock ring breaking power.

Do the stock piston ringlands usually give out on these motors at high horsepower? I haven't really seen that on this forum, only rod bending

[pbonsalb]

I think there is an example of it. Or maybe it was the ringland.

[JohnEastvold]

Just aiming for around 650-680whp and around 450tq

I mean I've seen blown engines on bone stock cars, ive seen stock block supercharged m3's handle good power with no issues also. Just the gamble for playing with power. I put down 590/430 on a dynojet SAE. 620/435 STD. Its a good amount of power but that extra push shouldnt hurt it. The key ive seen is just dont hammer it down low. Up high doesn't bend rods as much as flooring it down low. My max tq is around 7200rpm i believe. When its fueling is fixed it should move to around 7500rpm and max ho should move to around 8000-8200 from the 7600 its at now.

You don’t make any boost down low so there isn’t enough torque to bend rods down low. I think it’s just a function of light weight parts for high revving that aren’t designed for big power. A few chasing big power have broken these motors. Somewhere runaround 600/400 seems to be the safe limit. With the E85 you will hopefully be ruling out detonation as a problem.

Yeah the E85 is what im counting on to help against detonation

Been following this post for a minute. My favorite part.. OP does whatever he wants. Everyone tells him this is coming, this is going to happen, but it's his car, and only be knows what he wants, and his finances. GO FOR IT!

Thanks yeah if i wanna do something ima do it. Ive been running it lean like this since november and no issues minus spark plugs coming loose due to my improper installation lol. I raced my friends gt500 with e85, tune and pully making 600+whp and around 650tq and i beat him at my 600whpand 430wtw running lean. The cars doing great. I just know there is more she can take. If it blows then so be it. Rebuild it stronger or just get a different car all together. To me this is fun haha.

Why not turn it as soon as boost starts, so, in theory, you aren't ever straining the current pump?

You should drop the E85 use and run straight 100 until you install a fueling system that can support the additional volume required by E85. You're losing power by running it lean, and creating unfavorable conditions - you'd be better off dropping the boost and would probably make more power with less boost and the proper fueling. We target around 12.2 for safety - if you wanted a custom tune that ran a leaner mixture, you'd also see better results.

We have a customer in Colorado running 10PSI at 7K plus feet with the smallest supercharger pulley I've seen - stock motor. He runs 100 OCT and pulls 155-160 in the standing mile which is very impressive. At sea level he'd be at ~15 PSI.

I commend your bravery, but there is a fine line you are walking. It's not a question of if it's going to blow but when. Focus on providing the fueling it requires for these boost levels, and you can reduce that risk drastically and enjoy it for longer.

Thanks! After i get the fuel pumps and injectors in could we discuss a custom dyno tune? After the fuel system is in were going to take it straight to the dyno and see what if does. Could probably arrange to rent if out if you can do some custom remote tuning? I really am aiming to try and take full advantage of E85.

15 PSI with V3-TI?

Radium Engineering has something coming for us. Not sure if it's tested for a M3, but it's listed as a hashtag

well i got some GREAT news thansk to imgmotorsports! they sent me this link today from fuel-it...

http://www.fuel-it.com/bmw-e-series-...-lpfp-upgrade/


drop in fuel system for E85. i emailed fuel-it. told them my set up (10 psi on e85) and they said it is set up for that exact purpose. i would just need to drill in 2 holes on the top hat and be good to go. has optional hobs switch for 4psi. looks like ill be going this direction!

[M3PR]

Nice!! will go with this pump also. I have a ess 650 and really want to do the e85. subscribed

Did you get this installed? How's it working?
