2008 135i - AT - FBO (without meth) - JB4 - Pump 93
Stock 2011 5.0 with the new Coyote motor.

The outcome was as follows:
From a 40 roll, all 3 of us went. Myself and the 135i immediately put 2-3 cars on the 5.0 all the way until about 110 where we had a solid 4-5 cars on the 5.0 and then we all shut down. The 135i put 1 car on me before shutting down. This was done one more time to ensure consistency and the outcome was the same.

!Disclaimer! The above was conducted in Mexico.

I have JB4 with DCI...I run map5 AutoTune how would I add E85 combined with 93 Pump? Will it make a difference? Whats the best ratio of E85/93 Pump? What map would I leave it on?

They are much faster on E85 (there are several running 10s on E85 that I've seen).

I've go no doubt you did what you did, but don't let a local occurrence extrapolate into an assumption about how they all are. The N54's turbos do NOT flow enough air to keep up with a FBO 5.0 running the same gas. Just a fact of life.

maybe it's different here lol. bottom line they can't hang with me here. Oh well.

AK 335i · 11-03-2012, 10:33 PM

I'm not taking anything away from 5.0s they are bad ass. 5.0 will beat n54 just the same as n54 will beat 5.0. with both slightly modded its a grip and drivers game in the 1/4

And when I go to a muscle car shoot out and I'm the only non muscle car amongst 30 or so gt500s 5.0s and Mopars I seriously doubt they all suck at driving

with jb4 and dci only on 93 my best was 13.33
I put in 4 gal E85 to a full tank of 93 and ran 12.43 and 12.53
just keep on Map 5. 25% E85 will be fine with no headaches.

not with 20-25% E85 on map 5
If you run higher mixes you may have to tune out fueling issues

so basically more power if I leave it 20-25%, any known motor issues with E-85?

E85 for our cars is basically cheap race fuel. High octane, and also ethanol has a cooling effect in the combustion cylinders. My car loves it.. I run 25-30%... have been for months. Too much more E85 than say 40% and you'll probably run into fueling issues that you wouldn't get with race fuel.. but 100 octane race gas is what... $8 a gallon?

A 5 liter V8 and a 3 Liter I6 will never be apples to apples. Stock or otherwise.

can I leave the E85/93 Pump mix in the car or does it all have to be used up if the car is going to be sitting in the garage for a few days?

relax. it will be fine. I don't think I'd leave it sitting for a month.. Maybe I would? With that low of a mix you have nothing to worry about.

You are fine. Just mix in 2-3 gallons of E85 with your next fill-up of 93, switch the JB4 to map 5.

GTstunna612 · 11-04-2012, 11:43 AM

yes I will try it out

1000klr · 11-12-2012, 02:29 PM

ill chime in on this one because ive owned both...

my 335 was jb4/dci/dp and could only run a 13.26@105

my 5.0 with jon lund tune/steedaCAI/offroad xpipe/roushaxlebackexhaust 12.71@113

the bmw had more power low end but the coyote motor kills it up top

Something must have been wrong on your 335i, that time is barely better than stock?

injector on cylinder 5 did go out about 4 months down the road but had nothing to do with this run. if you're not running meth or larger turbos these n54's are not powerhouse's up top.

they spool low end and make awesome torque but thats no good at a track

While I do agree that N54's with stock turbo's aren't really powerhouses up top, they certainly do hold their own. Here is a run of my friends 135i with just a tune, fmic and downpipes and still on stock runflats:
