1M Power vs 135i N54
Hi
If the 1M and the 135i N54 are identical engines and exhaust (most of it) except for the folll known differences- 1. Rear axle different on the 1M 2. Radiator fan different on the 1m 850w versus 650W Fuel pump, turbo's,internals, oil cooler, FMIC etc all the same, why is there so much of a difference in claimed power increases between the 1M and the 135i N54 on a tuned flash? For example, if you look at what AC Schnitzer claims in respect of the power they produce with a 1M versus a 135I N54 it is substantial, and this applies to other tuners such as ESS as well. ANyone know why this is or is this just marketing? I would have thought the end result would be the same if these two cars in stock form and are tuned with a stage 1 flash alone?... This shouldnot be much different with an full exhaust set up as well.. ANy thoughts... |

Here's a bit on it from another post(take out the spaces): http://www.[Admin Notified].com...563#post197563 If the link isn't working, click quote and get the link info there or you could read this: Further driving experiences with this car, all I can say is that I really want a 1M... Also I googled this but didnt find any results, but Jeremy stated that BMW is using the Alpina motor in this car...lower compression, forged internals etc. He said his source in Germany confirmed it and just by looking at the standard tables in the DME, BMW left a LOT of room to move up . Fueling is still the limitation we think, only futher testing will see how far this goes. Also Alex from Gintani was there, I didnt even realize it was him until my friend informed me later on. Both of them are standup guys, I dont think there is enough good I can say. Last edited by Matt@Camber-Toe; 09-27-2011 at 06:15 PM. Last edited by UsualSuspect; 10-24-2011 at 06:48 AM..

1M's push more boost from the factory than a 135i (12-13psi compared to 7-8psi respectively), so that is why they make more power in stock form. Tune both, and I guarantee they will output similar power.

First of all, this exact topic has been discussed a hundred times.

A while ago, I think someone found out that the clutch and flywheel (and crankshaft and piston rings and a bunch of everything else supposedly "upgraded" for the 1M) are the same parts as on 2010 N54 cars. However, I think some of the parts were upgraded between 2008 and 2010, such as the flywheel, so in a sense it is still "upgraded" from the 2008 N54 cars.

I think I hears somewhere that the inlet manifold was different on the 1M too. TBH an N54 with the BMW PP has the same output as the 1M in the real world. When I had a "Stock" dyno done (with the BMW PP exhaust) I ran 312BHP when I had FMIC and the BMW PP added I ran 346 BHP. That's more than the 1M. Now I have the GIAC map too and rune 400BHP

I have not seen Yuchi's dton runs...
Also cannot see JHOOPS2 post. There seems to lost of speculation regarding what is perhaps upgraded on the 1M but nothing certain. Basically most tuners I have looked at like ESS, ACS etc state substantially more power to be made on a stock 1M with a flash versus a stock 135i N54 with a flash. I thought the two cars would make similar power as a end result with a stage 1 flash as there seems to minimal difference between the two.The only difference on the cooling is the 850w rad fan vs the 650w rad fan and the clutch/flywheel which cannot make a 40 hp additional gain. The oil cooler (at least our spec vehicles) are the same. The may very well be some different internals but the power difference shown by various tuners for these vehicles are substantial, thus just wanted to know how come... myabe they just tuning it more agrressivley as they want it to be stronger than the 135i with a tune.. |

There is no speculation...they are both N54B30 engines...except one has the ppk and a more aggressive tune from the factory...

Ohh and also a clarification. The 1M has 30 HP and Tq more than a 135. Dont include the overboost numbers when comparing the 2. The overboost is a 10 second cast or whatever with a long cooldown of a few hours I think (to put in Warcraft terms. So in reality the difference of the tune is 30...not 70 gagillion as you 1M boys like to think. |

Just remember I am comparring a stage 1 135i vs a stage 1 1M (both std excpet for tune) not stock vs stock. I am looking at the end result of the two cars tune. |

Are you talking something like a jb+ that nets like 30-40 hp? Well ofcourse they cant have that power out of a "stage 1" 1M. Try comparing JB4 or Procede numbers to these "stage 1" 1M. Youll se that theyre both the same at about 380ish hp. |
