R56 E85 for r56 owners?
E85 for r56 owners?
I have a gas station 1 mile for my house that has e85 and want to run it but I don't know what our stock injectors can flow or be jetted to flow , and what our ( in my case my jcw) fuel pump will flow ? Does anyone have the answers for this? I'm guessing a wali 255 pump will be needed. I'm hoping someone on here has done this I ran e85 in my srt4 and loved how it pulled under boost!! And it's a dollar less a gallon here so it saves on my wallet! Let me know thanks for reading my post!
The R56 has the Prince motor made by PSA. 1st gen had the tritec but not the same as SRT4. If BMW is freaking out about e15 they damn sure dont want you running e85. They are European and are not meant to run on any kind of ethanol.
Granted our internals stroke and bore are all different so that would play a huge factor! I just want to utilize the stock turbo and make the most power I can until my warrenty expires then I'm going with the gt28r turbo and suspension goodies in hoping to get into circuit racing !! I used to just love drifting my trans am ws6 and going straight but this car has made me a believer in going around corners!!
That's what I needed to know thankyou for the answer to my post! If you have any good infor you feel I need to know just send me a message! I do a lot of mechanic work so don't dumb anything down but as with all things mechanical every engine is different so there's a lot to learn about this motor still and I've never worked on one!

There is a lot of useful info on here to help you just beware there are a lot of tards here that don't get it and will nay say just about everything. Just search and you can find some good info.
Even it were feasible to run E85 in our cars, the price difference is not such a big deal when you figure in the decrease in gas mileage.
I've used E85 in my wife's minivan, which is made to run on the stuff; our gas mileage dropped by 30%.

Any names on here specifically I need to be aware of ? I know shops that are known for working on them and I can always call them but I like communicating on here with people I will be doing events etc. With
All the gas in my state has up to 10% ethanol but my SA has never blamed the gas on my cars various engine related issues. I sure hope the only thing I can even buy out here isn't ruining my car
Running e85 in a gen 2, especially considering how expensive the high preassure fuel pump is, is Ill advised...
It has been done on gen1..with 550cc inj instead of 340's.....and 2 different tunes for when youbswitch fuel....The volume needed to be pumped chages due to to the lower btu content of the fuel...more octane, yes, but lower btu's, more more volume is needed, and since the mini computer cannot adjust on the fly....you need custom Dino tunes...
So not worth...it will cost $$ to set up, void you warrenty, and you will be the first to try...heck, not even sure anybody has done it on a gen2....

I caused quite a S**T storm on here when I brought up running my R53 on E85. Everybody here seems to be totaly against it, its like its some sort of devil fuel to them that will distroy the motor, eat the engine block, and melt the fuel lines.
Truth is unless your fuel system is up to the task, you CAN royaly mess things up, but it can be done. It is verry important to have every part of the fuel system able to work atleast 50% harder than it does stock! On average you need 30-40% more fuel running E85 because of its lack of heat. Heres a short list of what you WILL need to change to run it reliably:
Fuel pump- 255 lph or higher, possibly external for ease of instalation.
Fuel injectors- At a minimum of 40% higher flow rate over stock, Might be a problem I havent seen any injectors avalible for the R56.
Tune- It is an absolute necessity that the car be tuned on a dyno by someone who has experiance with E85. Tuning regular fuel and E-gas is totaly different, AFR values are NOT the same as even 116oct race gas.
Fuel pressure regulator- In most cases you will want an adjustable regulator for ease of tuning.
Some NAM E85 MYTHS:
E85 will distroy your engine- NOT TRUE, the lack of tuning can, but E85 will NOT eat valves or any other metal part of the engine. (This was an arguement I found on here a while back.)
It will decintigrate your fuel lines- SOMEWHAT TRUE BUT, MOSTLY FALSE. E85 still has petroleum aditives to counteract alchohol's effects on rubber. It will litteraly take more than the life of the car to see any bad effects on rubber, or even the polyurithane fuel tank, as long as it is kept in circulation. If the car is being stored for 3 or more months without running, it can cause more rapid deterioration.
The savings at the pump arent worth the decrease in MPG.- That depends on the user and the purpose of the car. For daily drivers, it will even out and you WILL end up paying about the same as using 91-93oct. For track day, and weekend cars it will save you a bundle. At the track Ihave seen race gas as high as $11.00 a gallon, E85 is normaly around $2.00 a gallon, and they are the same octane rating! You do the math on that one. Or for an occasional use car, you will have all the power of race gas, but still only use a tank over the course of a weekend.
All in all, E85 is great for gearheads with track and weekend use cars looking for MAXIMUM power (Most cars when tuned properly for E85 see 20-30 more HP than a 91-93 tune alone.
). But for a daily driver its really your call.
Hope this helps, sorry for the long @$$ post but, you asked.

I have successfully run on E85 here in the UK, with a set of larger injectors and a tune to suit, and the engine loved it.
czar are the gains in the same ball park as what you would expect on a R53?
As I have not done any testing on the W11 engine from the R53 I can't honestly say!
However that said, the gain for the N14 engine, were very good indeed, BUT it's far from easy!
It's not just a simple case of swapping injectors! you need to look at fuel delivery too.

Thanks guys you have been a great help! I was expecting to need another fuel pump and 40% bigger injectors mainly because I had to do the same on my Audi tt and my srt4 just some engines don't handle it well was hoping for some answeres like you all gave me maybe I will wait until I upgrade my turbo cause then I will need all the goodies you just listed lol
Also the big problem is not the fuel pump and injectors you need to get different o2 sensors because you will burn those up or at least that is what I have heard from people putting e85 in their MINI.
this is not true, a correctly operating O2 sensor simply reads the oxygen content, and has no problem with E85 as your chosen fuel.
