I really don't want to ruin your thread, but honestly, shouldn't your 399 crank hp's perform a little better than this? Over 2 seconds slower 100-200 km/h is much, really much. Think about how long distance a car in 200 km/h will manage to travel in two seconds... My car has 435 crank hp's, and believe me, those 36 hp shouldn't make a two second difference in such a short speed range... Btw, the only differences in bolt-ons between our cars is that I have catless UR 2,5" DP's vs your catted AR 3" and that you have an AR oilcooler & Forge DV's vs my stock ones... Anyway, I wish you good luck with the Giac stage 2, which hopefully will make your car perform as it really should! |

For the time being I can't really judge about fuel consumption, but they certainly are a lot better also at giving me a smooth ride than the stock 17" RFT I had on at the beginning of this year. Alpina_B3_Lux

hi Marcel,
was a pleasure to read your tread(s)! I choose a different route by upgrading the suspension first with 18" semi slicks. Tranforms the car. if you want to feel how it drives, come to the NS tomorrow or friday, I'm there what are your plans regarding the diff? you've the same problem as I do I guess, welded... I'll ask my shop here tomorrow what they can do. will keep you posted if you want. cheers, from another Marcel |

I'll be upgrading to a Quaife diff next spring, as Tony already wrote in his post I'll make a trip to the UK and will leave my car at Bird's for two days (at least that's the plan), where they'll install the Quaife and the M3 suspension bits (and maybe other things, but that will have to be determined). And yes, I guess I also have a welded diff and will have to get a complete final drive unit, but well that's the way it is. I'll go to Bird's as I wanted to visit the UK anyway and they've got the best reputation for these installs. Keep me updated on what you'll be doing! Alpina_B3_Lux

I had several laps where I didn't see anybody. First time that happened. I have to check regarding quaife. The DKG has a completely different ratio. Changing it with an other complete final drive would mean a big shortening of my gears, which I do not want. They DKG already has quite close gearing. I am checking for other options as well. My shop near the NS offers "Lamelle" difs. Let's see when I receive the details. By the way, the power kit doesnot provide enough cooling. It is less warm, but today the oil still went up to 135 degrees, and this with outside temperatures of 12 degrees... So I will need to get myself the VK oilcooler to finally resolve the issue completely. |

I'm not surprised that without an additional oil cooler you see the temps still going to high on the track. I already assumed earlier on that an additional separate oil cooler is more efficient than a bigger water cooler - I can only assume that this solution may have been too expensive or complicated for BMW to offer (although then again Alpina offers it as an option...). If you track the car regularly, you may want to think about the ar design oil cooler that provides even more cooling. The only disadvantage is that it partially blocks the air intakes behind the grille, which is why I'll probably go with the STETT CAI in the near future. Well, I didn't do the mods myself, it was all done at a garage so I wouldn't be that much help to you! You can acquire all components of my modifications on the aftermarket, though, so if you would like to go down the same route it shouldn't be too complicated. Alpina_B3_Lux

would be fun, looking forward already! Now first a long dark winter....
not sure about a second oilcooler, as it is blocking airflow. With the VK one the temps should really be no issue. I was also thinking, that the oil temp is such a big issue, as I have DCT which is probably (almost sure) using the same oil for cooling, the same for the active steering... changing air intake is a "no-go" here in Switzerland. The Swiss TüV (MFK) is a PITA. A drop-in is the only thing you can do here (legally). |

Awesome writeup. When I picked up my E92, the first mods were: B&M SSK, round shift knob, CDV and coilovers. This made the car a lot more fun to drive. Handles before power.

Installation of it is scheduled for 19/20 February, along with the M3 suspension mods (front and rear) and Hartge sway bars. I haven't updated this thread for a while - although I've the catless DPs, secondary race cats and UUC short shift kit installed for two weeks now - as the current weather conditions do not allow me to properly test everything. As soon as I have done that (maybe I'll also find the time to do some datalogging with the BT tool) I'll write up an additional review of those mods. Alpina_B3_Lux

Looks like the long dark winter is coming to an end!
But you will love snow with the Quaife! Looking forward to review of how the ceramic coated DPs compare to catted version.
