Been pretty busy lately, but I wanted to post up a dyno of my car running on straight e85 from the pump, this is from about a month ago on a dynojet. Power delivery feels awesome and thankful I have a diff!

N54 135i 6MT
My mods:
BMS DCI
Procede V5 Rev 2.5
ProcedeFlash
Vishnu/FFTEC Inline booster pump
Vishnu/FFTEC ethanol sensor
AR Catless downpipes
Agency Power Midpipes
Berk axleback
Spec 2+ clutch
Steel SMFW

No Meth
Stock Intercooler
Stock Charge Pipe
Stock Diverter Valves
Stock Turbos

Ambient temps were around 60* I believe. Dyno'd in 4th gear.

OMG... That is sick bro. Nice numbers. Congrats...

[E90Company]

Well done!

[Ænema]

Nice, any baseline numbers?

Unfortunately not, but from what I hear, stock n54's put down around 270-280whp on this exact dynojet.

congratz. nice results. gotta love corn power

[RimasRS]

FTW no more words

but stock IC and no even meth...

[Mangler]

How many back to back runs do yo think that FMIC will handle, 1? maybe 1.5? That should have been your first mod.

[Lunatic Fringe]

Nice results. You've taken your car to several airstrip events, correct? How does the power hold up with the stock intercooler?

[The Ghost]

Nice run buddy!

I'd like to see a log of your IAT during a 1-4 gear run or two. There is a huge diff in IAT with a FMIC. You'll get much more consistency.

Just curious, what RPM do you shift at? That's a boatload of TQ down low.

When you run straight alcohol as fuel, the importance of charge temp is greatly diminished. In fact, most alcohol burning drag cars don't even have intercoolers because the cooling effect of the fuel (when it vaporizes) is so strong. This is not seen in datalogs which measure IAT before the in cylinder cooling event. And it's really the temp in the cylinder that matters.

Tq falls off a cliff but theres nothing you can do about that. Peak numbers are pretty incredible for no meth and stock intercooler. Very nice!

[WLF]

Great numbers ... i wish you had a dyno graph for yr car stock

[Continue5]

Are you telling us that we can get numbers like this with mods like that after the open source software has been released? (july 4th?)

Btw may be you have some dyno numbers used with 50/50 mix, or 30/70???

Is that a serious question?

Exactly. In cylinder temp is the most important metric that matters in this case given the fuel involved. Leave it to all the know-it-alls to think differently though.

Charge pipe is on the way, intercooler is next . This was the first time my car had ever been dyno'd before, I wish I would have done a baseline in the past, or at least a pull on 91 Octane, but I'm happy with the results so far, and as far as how many pulls I can do before I start to see a dip in power, when it was ~65* outside, I did 6 pulls against a cammed/tune/headers 2012 Camaro SS, pulled about 3-4 cars by 120 the first 5 pulls, then on the 6th, he started to catch me, so I did notice a little bit of a drop in timing, but I'm hoping I'll be able to sustain the boost a little better with the charge pipe, as well as reduce IAT's for peace of mind with a FMIC. Thanks for the feedback guys!

Agreed...but even then, the DME will be inclined to pull out timing if it senses CATs that it doesnt like. Even assuming in cylinder temps looks great thanks to the ethanol. On repeated pulls I gotta think an upgraded FMIC would be of benefit. Regardless, that type of wtq on stock turbos is incredible.

Dmacc what type of peak boost are you seeing? You must be spinning those things pretty good.

I short shift around 6100 RPMs, 500tq at 3000rpm feels like a kick in the pants!
