Thanks. I don't want anyone to spend any money they don't want to. I do want out community to be educated so you can decide what mods best fit our needs. There is no question now on how the stock IC performs on the real roads and there is no question on how well the Active Autowerke Intercooler performs now either.

Good information. Will you be doing any extended runs? Back-to-back WOT are great, but I want to see how the I/C impacts a 30-60 minute track session in 90F ambient temps.

Bubbles, thanks. I have no plans on doing long track events. That is not my cup of tea. The back to back long gear pulls tells us this IC takes a very long time to heat soak. The stock IC basically heat soaked after multiple long gear pull.

T-bolts do look nice and function well, but with these tiny turbos they are probably way overkill. Both the IC and the passenger/driver side piping all have lips so the provided clamps should hold up quite well. If they showed I would update them for looks. |

Great review, and numbers. It really appears that the stock intercooler is useless at anything higher then stock boost, and even then might be questionable.

Mike I think you are spot on. The stock intercooler is really a very poorly functioning part and I think the testing shows it must be in the top 3 items replaced on the car.

Perhaps tbolts would be overkill... But my driver/passenger side connectors and couplers did not come preassembled like yours, and I was having issues with coupler fitment and hose length during my install.
I popped a hose (which actually came loose off the passenger side coupler) and when I went to address the problem found that I had a boost leak from that area as well. I also noticed another clamp had worked it's way down and OVER the coupler's bead instead of behind it. To correct the issue, I had a new coupler fabricated for that side (and the opposite coupler rebeaded), and went ahead and got new silicone hoses from turbohoses.com as well as replace all the clamps. I'm not necessarily blaming the clamps but the oil that accumulates in the intake tract may have played a role, and nice quality clamps never hurt. And correct me if I'm mistaken, didn't the code3/spearco come with tbolts? I believe the helix also came with some really nice clamps as well... In any case OP, great review and data you've presented here! Anyone who goes to the AA FMIC would be very happy with their purchase :-) |

You probably won't to be honest. I may at some point in the future, but only if I get some new parts like an exhaust. The reason is the intercooler has two purposes:
1. Cooling the air from the inlet to the outlet side 2. Pressure loss We know the pressure loss is about 1 psi less than the stock IC, so essentially you can up the boost now by about 1 psi and the turbos will work the same amount. We know the pressure loss is less and the AIT decrease is around 40 degrees F, so we have all the data that is needed. You will see people argue on this forum with dyno numbers but ask Helix or AA or Spearco or RPI and they will tell you the data I am providing shows the results. It must produce more power now because of the results I showed. Now I can run more boost and get more power out of every pull. The dyno is more a function of the fan than anything else. The air goes across the intercooler in real life as a function of your speed. On the dyno it is essentially constant, so my tests show it does produce more power without any argument. When comparing IC's you need to look at pressure loss and AIT drop to compare. |

I am actually a little disappointed with those results. The best IC's on the Market usually only see around a 10 degree rise in IAT's over a full 3rd gear pull and they use Garret Cores, which that is not.
Obviously still much better than stock though. |

Nah... No need. Popped that hose after a good 10k with the FMIC.
I noticed I had a good amt of oil in the endtanks though and I'm not looking forward to cleaning that out LOL! |

Some people that were asking about dynos probably don't recall the dynos that I did.
Here was my review with dynos: http://www.e90post.com/forums/showth...0106&highlight I had JB2H at the time. This was a great review!! MUCH more detailed than mine!

CanadianTSi, this was a rise of 35 on full long gear pulls. The AIT rise over ambient has more to do with the turbos on this car than the intercooler. The intercooler is doing a very good job.

I definately agree the stock FMIC is a major weak link in our N54's and there are several great options out there to upgrade it. I think anyone will notice a significant performance improvement when they upgrade. I was really suprised how much difference I could feel. Also cutting is no big deal. I was a little discouraged at first when I realized how much I needed to cut for my 135i, but after I was finished it looked clean and it was nice to get the plastic that is partially blocking the intercooler on my 135i out of the way. I used a $3 mini hack saw for the cutting and it worked great and my bumper stayed on the whole time. The dremel cut-off wheel was not usefull for me. |

Good thinking! I should have tried that. I gave up after about ten minutes of using the dremel cut-off wheel, I kept breaking the wheels and it seemed to take forever to cut. Luckily i had the mini-hack saw which worked suprisingly well.
