N55 FBO dyno results

[M135]

A few weeks ago we headed out to Cincy Speed for a small dyno day with some friends.

Weather: 77 degrees with humidity around 78%
Car: 2011 135i - 9,500 miles - 6MT
Mods: JB4 beta firmware (did not update before dyno), Map 7, BMS DP, BMS intake, ER charge pipe, ER FMIC, 4 gallons e85 w/rest 93

Map 5 - 350/409
Map 7 - 369/432

I plan to go to the final release of the new firmware and add e85 wires soon.

nice numbers man!

[ParkNuts]

Holy crap that's a lot of torque. Is your car very consistent on the street? I'd think with all that boost it might hit a little too hard and uncontrollably. Also, do you have much boost drop between shifts or can you grab each gear and be in boost pretty much instantly?

Yes, this is in my normal street trim. I have some street vids vs. a FBO meth n54 135 I will post later. I do lose boost during shifts and can't wait for BMS to add no lift shift to the jb4

I also can vouch that street drive ability is lacking. In the rain on my DPE wheels (summer tires) with DTC on it hydroplaned into a curb and bashed my wheel bad (hence the stockers in the Dyno vid)

Great numbers again man! I can not wait to see what she does when the weather breaks and we get back up there.

Still think you need to add meth and race to see if you can hit 400whp!

[M135]

Thanks bud, I agree. I want to do race gas first and then see what I can do with meth, then both

You could go ahead and get both...
1 pull map 0
1 pull map 7
1 pull map 3

Or spend the extra $40 and get 2x pulls!

DO IT!!!

Can you expand a little on how it's lacking? Is the throttle too sensitive? Boost hits too hard? Maybe turn down lagfix? Ever throw it into map 0 for easier driving?

Sorry for so many questions. I have a dct car but my tranny is giving me too much headache so I want to get into a 6 speed car and I'd like to know a little before I get into modding a 3 pedal version of my car.

[M135]

Lacking as in rolling in 1st or 2nd gear and laying a bit into throttle will send you sideways in a hurry. It as fun as hell to drive when you want to have fun, but you have to be conscious of it all the time.

I have not put it into map 0 for easier driving as it really is not my daily driver.

Thanks. Dyno vid of the actual pulls are in the first post, and here is me and trickcruiser going at it http://www.youtube.com/watch?v=oAaE9BR0YZ4&feature=youtube_gdata_player

Remember he is n54 FBO with meth

[Golden3ye]

I would have thought those numbers would have been higher for full bolt on. What are the numbers for a FBO n54 minus meth

[M135]

It's tough to nail down a hard FBO n54 dyno number with no race gas. I am seeing in my Google searches of n54tech, BMS website, and 1addicts anywhere from 378/385 to around 410/420

BUT....Terry's dyno with WW meth is here:

I think I need to get a meth kit and hit the dyno to nail down a 400 number for the N55

One thing you have to remember is that every dyno is going to read differently. The reasons are temp, humidity, calibration, operator, and so on...

Here are the numbers that I have for reference though.

My N54 335i - JB4 18ohm - FBO - Downpipes - Cool 70 day - 93 octane
Map 2 - 370/380

My N54 135 - JB4 18ohm - FBO + Meth + 93 octane - 80 degree day
Map 3 - 50add - 401/433

My N54 135 - JB4 G5 - FBO + Meth + 109 - 80/90 degree day
Map 3 - 75add - 433/473
Map 0 - 293/299
